Description

Technical Field

[0001] This invention relates to the field of heat shrink tubing inspection technology, specifically to an integrated device for online detection of foreign objects inside heat shrink tubing and for cutting and connecting tubing. Background Technology

[0002] The general production process of heat shrink tubing is as follows: first, the polymer raw materials and additives are mixed and extruded, cooled, then subjected to radiation cross-linking, followed by heating to expand and cooling to set the shape, and finally cut, inspected and packaged to produce the finished product.

[0003] During the extrusion molding process of heat shrink tubing, residues inside the extruder may mix into the tubing, affecting its performance and leading to poor quality. Because foreign objects inside the tubing vary in size, they are sometimes difficult to identify accurately, resulting in inferior tubing reaching customers and causing complaints. Furthermore, manual inspection is inherently costly, and the inability to promptly address foreign objects can disrupt production. Therefore, a device is needed to perform online detection of foreign objects inside heat shrink tubing, automatically removing the affected sections and reconnecting them to ensure production quality, reduce manual intervention, and keep pace with production.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1) This device can be integrated into the downstream of the heat shrink tubing expansion process. A traction mechanism guides the heat shrink tubing throughout the device to complete various processing steps. First, the traction mechanism automatically detects foreign objects inside the heat shrink tubing. When foreign objects are found, a sealing mechanism seals the foreign object section. Then, a cutting mechanism automatically removes the foreign object section. Finally, a flipping mechanism and an adhesive applicator bond both ends of the heat shrink tubing together. After foreign object removal, the heat shrink tubing can proceed to other subsequent processes. This device achieves full automation of the entire process, including foreign object detection, sealing of foreign object sections, removal of foreign object sections, and re-bonding of the heat shrink tubing, without manual intervention. This automated online detection and handling of foreign objects inside the heat shrink tubing reduces labor costs, improves detection efficiency, and matches production rhythm.

[0024] 2) When there are impurities or foreign objects inside the heat shrink tubing, the thickness of the heat shrink tubing will change. This device can detect the slight thickness changes of the heat shrink tubing through a displacement sensor, so as to detect small foreign impurities, improve the detection accuracy, and ensure the production quality of heat shrink tubing.

The flipping mechanism assembly includes... Two independent flipping mechanisms 4 are respectively the first flipping mechanism and the second flipping mechanism arranged from front to back along the travel direction of the heat shrink tubing.

[0064] Example 2

[0065] See Figures 1-16As shown, this embodiment of the invention provides an online pore-clogging detection device for heat shrink tubing, including a front traction mechanism 1 that provides traction power to the heat shrink tubing and a mechanism housing 9. One side of the mechanism housing 9 is fixedly connected to the front traction mechanism 1. Inside the mechanism housing 1 are a detection traction mechanism 2 for detecting foreign objects inside the heat shrink tubing, a sealing mechanism 3 for sealing the foreign object section inside the heat shrink tubing, a flipping mechanism assembly for flipping the heat shrink tubing, a tube-cutting mechanism 5 for cutting the foreign object section inside the heat shrink tubing, an adhesive-applying mechanism 6 for bonding the heat shrink tubing, and a rear traction mechanism 7 that provides traction power to the heat shrink tubing. The flipping mechanism assembly includes... Two independent flipping mechanisms 4 are respectively the first flipping mechanism and the second flipping mechanism arranged from front to back along the travel direction of the heat shrink tubing. The tube cutting mechanism 5 and the adhesive applicator 6 are located between the first flipping mechanism and the second flipping mechanism. The detection traction mechanism 2 and the sealing mechanism 3 are arranged sequentially between the front traction mechanism 1 and the first flipping mechanism. The rear traction mechanism 7 is located behind the second flipping mechanism. The heat shrink tubing 10 can pass through the front traction mechanism 1 and the interior of the mechanism housing 9 in sequence. The detection traction mechanism 1 includes displacement sensors 2-7 for detecting changes in the thickness of the heat shrink tubing.

[0066] In a specific embodiment of the present invention, the mechanism housing 9 includes a main substrate 9-1, a mechanism cover plate 9-2 located above the main substrate, and a substrate support located below the main substrate. The mechanism housing 9 is provided with an electronic control component 8. A front traction mechanism 1 is provided on the front side of the mechanism cover plate 9-2, and a material dropping frame 11 is provided on the rear side.

[0067] In this embodiment, as Figure 3As shown, the front traction mechanism 1 mainly includes: a first traction base plate 1-16, a first limiting roller assembly 1-1 placed at the front end of the first traction base plate 1-16, a first motor 1-3 placed on the first traction base plate 1-16, and a first driving roller assembly 1-2 placed on the output shaft of the first motor 1-3; a first driven roller assembly 1-4 placed on the first traction base plate 1-16 through a first driven roller connecting component, wherein the first driven roller connecting component includes a first swing arm 1-5 and a first cantilever pin 1-6, that is, the first driven roller assembly 1-4 is placed on the first traction base plate 1-16 through the first swing arm 1-5 and the first cantilever pin 1-6, and is located above the first driving roller assembly 1-2; two rollers 1-7 are placed on the first traction base plate 1-16 through a roller connecting component, wherein the roller connecting component includes a second swing arm 1-5 and a first cantilever pin 1-6. The first traction base plate 1-16 is composed of a rod 1-8, a first shaft 1-14, and a first bearing 1-9. Specifically, two rollers 1-7 are mounted on the first traction base plate 1-16 via the second rocker arm 1-8, the first shaft 1-14, and the first bearing 1-9. The first bearing 1-9 is fixedly mounted on the first traction base plate 1-16, and it is rotatably connected to one end of the second rocker arm 1-8 via the first shaft 1-14. The other end of the second rocker arm 1-8 is fixedly connected to two opposing rollers 1-7. The two rollers are located behind the first active roller assembly 1-2. The second rocker arm 1-8 is positioned between two limiting pins 1-10. A first detection plate 1-12 is mounted on the second rocker arm 1-8, and two first sensors 1-11 are mounted on the first traction base plate 1-16, located behind the first detection plate 1-12. The front traction mechanism 1 is mounted on the main base plate 9-1 via a first connecting plate 1-15. The front traction mechanism 1 of this device is connected to the rear end of the heat shrink tubing expansion process. Because the expansion process at the front end continues, the first motor 1-3 will continuously traction the heat shrink tubing. However, during the subsequent sealing and cutting processes, the rear traction motor will stop working, causing the heat shrink tubing to accumulate at the front traction mechanism 1. When the heat shrink tubing is piled up, the tubing will sag, causing the second swing arm 1-8 to sag. After the first sensor 1-11 detects this, once the plugging and connection are completed, the rear motor will accelerate the traction, gradually straightening the heat shrink tubing. During this process, the roller will drive the second swing arm 1-8 to rise, triggering another first sensor 1-11. The rear traction motor will then decelerate until the front and rear speeds are balanced. This process controls the continuous and normal traction of the heat shrink tubing.

[0068] In this embodiment, as Figure 4As shown, the detection traction mechanism 2 mainly includes: a first base plate 2-17 is provided on the detection base plate 2-11, and a third active roller assembly 2-1 is placed on the first base plate 2-17 through a third active roller connecting component.

[0080] In this embodiment, some basic components used in each mechanism, such as electrical control components, driving roller components, driven roller components, gear components, heat insulation components, etc., are used. The so-called components mainly include the component itself and its related connecting components. Unless otherwise specified, the connecting structure components and connection methods commonly used in the field of mechanical design are adopted and will not be described in detail.

[0081] The specific working process of the online tube shrinkage and hole blockage detection device in this embodiment is as follows:

[0082] Preparation: Place the adhesive tape 6-3-3 into the adhesive tape holder assembly 6-3-1 and fix it in place. Pass one end of the adhesive tape 6-3-3 through the third shaft 6-3-14, below the pressure top piece 6-3-12. Use the fifteenth cylinder 6-3-9 to push the first pressing head 6-3-11 to clamp one end of the adhesive tape 6-3-3, leaving about 10mm of the tape exposed.

[0083] Adjust the width of the first limiting roller assembly 1-1 and the second limiting roller assembly 7-15 to match the width of the heat shrink tubing 10. After the heat shrink tubing expands, pass it sequentially through the first limiting roller assembly 1-1, the first active roller assembly 1-2, the roller 1-7, the third active roller assembly 2-1, the cold pressing base plate 3-4, the pressing base plate 4-7, the first movable base plate 5-3-1, the second movable base plate 5-3-2, the pressing base plate 4-7, the second limiting roller assembly 7-15, and the second active roller assembly 7-1 into the material drop frame 11. Close the mechanism cover plate 9-2 and start the equipment.

[0084] 1) The heat shrink tubing circulates throughout the device: The first cylinder 2-14 on the traction mechanism 2 drives the third driven roller assembly 2-10 to press down, and the sixteenth cylinder 7-11 on the rear traction mechanism 7 drives the second driven roller assembly 7-7 to press down. Subsequently, the first motor 1-3 drives the first active roller assembly 1-2 to rotate, the second motor 2-4 drives the third active roller assembly 2-1 to rotate, and the sixth motor 7-4 drives the second active roller assembly 7-1 to rotate, thus tractioning the heat shrink tubing. The traction speed of the second motor 2-4 and the sixth motor 7-4 is determined by the position detection of the second swing arm 1-8 by the first sensor 1-11, and automatically matches the traction speed of the first motor 1-3. After the traction speed of the first motor 1-3 is adjusted, it maintains a constant speed for traction.

[0085] 2) Automatic detection of foreign objects inside heat shrink tubing: The principle for detecting foreign objects inside heat shrink tubing is that the thickness of the heat shrink tubing may have a certain tolerance variation under normal circumstances. When the thickness change is gradual and within the normal tolerance range, it is considered normal. If the thickness suddenly increases and decreases, and the change range exceeds a certain proportion, it is considered abnormal, and it is determined that there is a foreign object inside the heat shrink tubing. In this device, when there is a foreign object inside the heat shrink tubing, the thickness will change abruptly, causing the third driven roller assembly 2-10 to move upward, thereby driving the detection plate 2-9 on the sliding base plate 2-13 to move upward. The pre-pressure stroke of the displacement sensor 2-7 will decrease, thereby detecting the change in displacement. At this time, after determining that there is a foreign object inside the heat shrink tubing, the second motor 2-4 and the sixth motor 7-4 stop rotating and pulling.

[0086] 3) Sealing the foreign object section of the heat shrink tubing: The second cylinder 3-1 moves the second base plate 3-2 forward, placing the heat shrink tubing 10 between the lower heat sealing assembly 3-14 and the upper heat sealing assembly 3-15. The fourth cylinder 3-9 drives the upper heat sealing assembly 3-15 downward, and the fifth cylinder 3-12 drives the lower heat sealing assembly 3-14 upward, thereby heating the heat shrink tubing 10 for several seconds. Then, the fourth cylinder 3-9 drives the heat sealing assembly 3-15 back to its original position, and the fifth cylinder 3-12 drives the lower heat sealing assembly 3-14 back to its original position. The second cylinder 3-1 moves the second base plate 3-2 backward, and the third cylinder 3-6 drives the cold pressing top plate 3-5 downward, cold pressing the heated section for several seconds. The third cylinder 3-6 drives the cold pressing top plate 3-5 back to its original position, completing the first sealing process of the heat shrink tubing 10. Then, the second motor 2-4 and the sixth motor 7-4 rotate again, pulling the heat shrink tubing 10 a certain distance before stopping, repeating the previous sealing action to seal the impurities between the two sealing sections.

[0087] 4) Automatic Cutting of Foreign Object Sections from Heat Shrink Tubes: The second motor 2-4 and the sixth motor 7-4 rotate, pulling the heat shrink tube 10 and positioning the rear end of the first sealing section of the heat shrink tube 10 at the cutting position, specifically at the interval between the first movable base plate 5-3-1 and the second movable base plate 5-3-2. The ninth cylinder 5-3-3 moves the first movable base plate 5-3-1 upward, and the tenth cylinder 5-3-4 moves the second movable base plate 5-3-2 upward. The seventh cylinder 5-2-9 simultaneously moves the first pressure-cutting plate 5-2-10 and the vacuum suction cup 5-2-11 downward. The first pressure-cutting plate 5-2-10 fixes the heat shrink tube 10 in place, ensuring it does not move during cutting, while the vacuum suction cup 5-2-11 holds the heat shrink tube 10 in place. The eleventh cylinder 5-4-1 drives the first blade 5-4-4 to move back and forth, cutting the heat shrink tube 10. After the heat shrink tubing 10 is cut, the seventh cylinder 5-2-9 retracts, causing the first cutting plate 5-2-10 and the vacuum suction cup 5-2-11 to move upwards. The vacuum suction cup 5-2-11 will hold the heat shrink tubing 10 and move it upwards. The fifth motor 5-2-1 drives the second suction tube base plate 5-2-8 to translate via the second drive gear assembly 5-2-2 and rack 5-2-4, so that the vacuum suction cup 5-2-11 will drive the heat shrink tubing 10 to translate a certain distance. At the same time, the second motor 2-4 rotates, synchronously pulling a section of heat shrink tubing until the second cutting plate 5-2-13 is above the cutting position, at which point the fifth motor 5-2-1 and the second motor 2-4 stop rotating. The eighth cylinder 5-2-14 drives the second cutting plate 5-2-13 to move downwards, pressing the heat shrink tubing 10, and the eleventh cylinder 5-4-1 drives the first blade 5-4-4 to move back and forth to cut the heat shrink tubing 10. The eighth cylinder 5-2-14 drives the second cutting plate 5-2-13 to move upward. The fourth motor 5-1-4 on the linear module mechanism 5-1 drives the tube pressing and suction mechanism 5-2 to move backward, the vacuum suction cup 5-2-11 releases suction, and the sheared heat shrink tube falls onto the blanking plate assembly 5-5 and slides out of the equipment.

[0088] 5) Automatic bonding of two heat shrink tubing units using adhesive tape: The first pressing head 6-3-11 clamps the adhesive tape 6-3-3, and the fourteenth cylinder 6-3-5 pushes the adhesive substrate 6-3-6 to the left end, thereby pulling out the adhesive tape 6-3-3. Then, the sixteenth cylinder 6-3-17 drives the second pressing head 6-3-18, and the upper pressing head 6-3-19 clamps the adhesive tape end. The fifteenth cylinder 6-3-9 drives the first pressing head 6-3-11 to move down, thereby releasing the adhesive tape. The fourteenth cylinder 6-3-5 pushes the adhesive substrate 6-3-6 back to the right end.

[0089] The fifteenth cylinder 6-3-9 drives the first pressing head 6-3-11 to move upward, clamping the adhesive paper 6-3-3 again. The linear module mechanism 5-1 drives the adhesive paper suction mechanism 6-1 to move forward through the translation substrate 5-1-8. The vacuum suction plate 6-1-2 moves above the adhesive paper 6-3-3. The twelfth cylinder 6-1-3 drives the vacuum suction plate 6-1-2 to move downward, and the vacuum suction plate 6-1-2 sucks up the adhesive paper 6-3-3.

[0090] The thirteenth cylinder 6-2-1 drives the second blade 6-2-8 to move back and forth, thereby cutting the adhesive tape 6-3-3. The sixteenth cylinder 6-3-17 drives the second lower pressure head 6-3-18 and the upper pressure head 6-3-19 to release the adhesive tape end. The twelfth cylinder 6-1-3 drives the vacuum suction plate 6-1-2 to move upward, and the vacuum suction plate 6-1-2 sucks away the cut adhesive tape 6-3-3.

[0091] The linear module mechanism 5-1 moves the adhesive paper suction mechanism 6-1 backward via the translation substrate 5-1-8, positioning the vacuum suction plate 6-1-2 above the heat shrink tubing 10. The twelfth cylinder 6-1-3 then moves the vacuum suction plate 6-1-2 downward, attaching the adhesive paper to the heat shrink tubing and connecting the two ends of the tubing together. The vacuum suction plate 6-1-2 releases its suction force, and the twelfth cylinder 6-1-3 moves the vacuum suction plate 6-1-2 upward.

[0092] 6) Flip the heat shrink tubing and apply adhesive tape to both sides: The ninth cylinder 5-3-3 moves the first movable base plate 5-3-1 downwards, and the tenth cylinder 5-3-4 moves the second movable base plate 5-3-2 downwards. The sixth cylinder 4-13 pushes down, and under the action of the spring 4-9, the upper pressure plate 4-8 moves down, clamping the heat shrink tubing 10. The third motor 4-1, through the first driving gear assembly 4-3 and the driven gear 4-4, drives the flipping plate 4-6 to rotate 180°, thus flipping the heat shrink tubing. Repeat the previous tape application process. After tape application, the third motor 4-1, through the first driving gear assembly 4-3 and the driven gear 4-4, drives the flipping plate 4-6 back to its original position. The sixth cylinder 4-13 pushes up, moving the lifting plate 4-12 upwards, which in turn moves the upper pressure plate 4-8 upwards, releasing the heat shrink tubing 10. The processed heat shrink tubing can either fall into the material drop box or be directly connected to subsequent processes.

[0093] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
