Description

Technical Field

[0001] This invention relates to the field of sealing technology, and in particular to a processing apparatus and method for ultrasonic sealing of an insulating heat shrink tubing structure. Background Technology

[0002] Ultrasonic sealing technology has been widely used in the sealing of materials such as insulating heat shrink tubing due to its advantages of high efficiency, cleanliness, and reliable connection. Traditional ultrasonic sealing devices typically use power components such as cylinders to apply a constant pressure force directly or indirectly to the workpiece. During the sealing process, an ultrasonic generator causes frictional heat to be generated on the contact surfaces of the workpiece until they melt and bond together.

[0003] However, in practical applications, it has been found that this constant-pressure sealing method has certain limitations. First, during the sealing process, as ultrasonic energy continues to act, the sleeve material gradually softens and melts, and its physical form and mechanical strength undergo dynamic changes. If the applied pressure remains constant, there may be a situation where the pressure is relatively insufficient during the material softening stage, which cannot ensure that the molten material fully fuses and forms under the optimal pressure. This affects the sealing strength and appearance consistency at the sealing point, resulting in unstable sealing quality.

[0004] Secondly, the level of automation and intelligence of existing equipment still needs to be improved. After sealing, the judgment of product quality mostly relies on manual visual inspection or simple mechanical limit judgment. For defective products, manual identification and sorting are usually required, which not only increases the labor intensity of operators, but also affects the overall production efficiency and process continuity.

[0005] Therefore, we propose a processing device and method for ultrasonic sealing of insulating heat shrink tubing structures to solve this problem. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings mentioned in the background art by providing a processing apparatus and method for ultrasonic sealing of an insulating heat shrink tubing structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A processing apparatus for ultrasonic sealing of an insulating heat shrink tubing structure, comprising: Pressure self-reinforcing structure: includes two cylinders, a pressure plate and a right sealing plate. An arch plate is fixedly connected to the top of the base plate. Both cylinders are fixedly connected to the right side of the same arch plate. The output ends of both base plates are fixedly connected to the same left sealing plate. The pressure plate is slidably connected to the right side of the left sealing plate. The right side of the pressure plate moves against the left side of the right sealing plate. The self-testing structure for sealing the tail includes two second touch sensors, two built-in slots, two side blocks, and a baffle. The two second touch sensors are fixedly connected to both sides of the same right sealing plate. The two built-in slots are both located on both sides of the same right sealing plate.

[0008] Preferably, the left sealing plate has an internal movable groove, and two trapezoidal columns are fixedly connected to the left side of the pressure plate.

A nickel alloy high-expansion metal sheet is bently connected to the opposite side of each of the two square plates on the same side. A low-expansion metal sheet of alloy is bently connected to the left side of each of the two nickel alloy high-expansion metal sheets. A connecting block is fixedly connected to the right side of each of the two nickel alloy high-expansion metal sheets. The pressure plate is fixedly connected to the right side of the two connecting blocks.

The left side of each of the two low-expansion metal sheets of alloy is movably abutted against the right side of the corresponding first touch sensor. The two first touch sensors are electrically connected to two cylinders.

[0009] Preferably, the top of the base plate is fixedly connected to two support plates, and the top of each of the two support plates is fixedly connected to a side plate. The right sealing plate is fixedly connected to the opposite side of the two side plates. The inside of the right sealing plate is provided with a sealing mold groove. The pressure plate movably abuts against the inside of the sealing mold groove. The right side of the baffle is fixedly connected to two toothed plates. The inside of each of the two side plates is provided with a first rectangular groove. The two toothed plates are slidably connected to the inside of the corresponding first rectangular groove. The right side of each of the two toothed plates is fixedly connected to two first springs. The right ends of the two first springs on the same side are fixedly connected to the inner wall of the corresponding first rectangular groove. Gears are rotatably connected to both sides of the right sealing plate. The two gears are meshed with the top of the corresponding toothed plates.

[0010] Preferably, guide posts are fixedly connected inside the two built-in slots, the two side blocks are slidably connected to the outside of the corresponding guide posts, a second spring is fixedly connected to the right side of the two side blocks, the right ends of the two second springs are fixedly connected to one side of the inner wall of the corresponding built-in slot, and a row of thorns is fixedly connected to the bottom of the two side blocks, with the two row of thorns movably abutting against the top of the corresponding gear.

[0011] Preferably, two positioning posts are fixedly connected to the right side of the left sealing plate, and two circular grooves are provided on the left side of the right sealing plate. Trapezoidal disks are slidably connected inside the two circular grooves. The right ends of the two positioning posts are movably abutted against the left side of the corresponding trapezoidal disks. Third springs are fixedly connected to the right side of the two trapezoidal disks. The right ends of the two third springs are fixedly connected to the right side of the inner wall of the corresponding circular groove. Ejector plates are fixedly connected to the opposite side of the two trapezoidal disks. The two ejector plates are slidably connected to the inner wall of the same sealing mold groove. Two grooves are provided on the right side of the inner wall of the sealing mold groove. The right sides of the two ejector plates are movably abutted against the inner wall of the corresponding grooves. Both ends of the U-shaped post are movably abutted against the left side of the corresponding trapezoidal disk.

[0012] Preferably, a frame is fixedly connected to the top of the base plate, an elliptical guide rail is fixedly connected to the bottom of the frame, four clamping plates are slidably connected to the bottom of the elliptical guide rail, two controllers are fixedly connected to the top of the elliptical guide rail, the two controllers are electrically connected to two second touch sensors, two guide plates are fixedly connected to the top of the base plate, and the collection frame is slidably connected to the top of the two guide plates.

[0013] Preferably, a power supply is fixedly connected inside the right sealing plate, and an ultrasonic generator is fixedly connected to the output end of the power supply. The ultrasonic generator is located on the right side of the sealing mold groove, and a heat sink is located directly above the power supply. The heat sink is fixedly connected to the top of the right sealing plate.

[0014] This invention also provides a method for ultrasonically sealing an insulating heat shrink tubing structure, applied to the aforementioned ultrasonic sealing apparatus for insulating heat shrink tubing structures, comprising the following steps: S1: Set up a defective collection box on the left side of the elliptical guide rail, then start the elliptical guide rail and clamping plate. The clamping plate clamps the sleeve to be sealed and moves it to the top of the baffle before releasing it. The device pauses to wait for the sealing operation. Then start the cylinders on both sides to drive the left sealing plate to move to the right. Under the push of the left sealing plate, the right side of the sleeve abuts against the left side of the right sealing plate, and the inner walls of the top of the sleeve fit together, thus completing the preparation work. S2: Turn on the power to start the ultrasonic generator. Its high-frequency vibration causes intense friction on the sleeve contact surface and instantly generates local high-temperature molten material. At this time, the high temperature generated by the ultrasonic generator is conducted to the second rectangular grooves on both sides through the pressure plate, causing the nickel alloy high expansion metal plates on both sides to bend due to heat, which drives the pressure plate to move to the right. Under the condition that the pre-pressure remains unchanged, the thickness of the sleeve is reduced due to the melting at the top of the sleeve. The rightward movement of the pressure plate can achieve automatic pressure compensation, thereby ensuring that the pressure at the top of the sleeve is sufficient during the sealing process. S3: As the ultrasonic generator continues to work, the temperature rises further. The pressure plate continues to move to the right and enters the sealing mold groove. At the same time, the positioning columns on both sides abut against the left side of the corresponding trapezoidal plate and move to the right. This drives the ejector plates on both sides to move to the right until they abut against the inner wall of the corresponding groove. At this time, the sleeve is close to the right side of the inner wall of the sealing mold groove. When the temperature continues to rise to a certain value, the low expansion metal plates of the tile alloy on both sides begin to bend and eventually trigger the first touch sensors on both sides. This is used as the criterion for determining whether the sealing temperature meets the standard. S4: During the sealing process, the left sealing plate moves the spiral column to the right. The two ends of the spiral column abut against the left side of the corresponding side block and push the side block to the right. At this time, the serrated spikes at the bottom of the side block are not engaged with the gear. If the sealing is qualified, the movement of the left sealing plate at the standard sealing temperature will cause the two side blocks to abut against the left side of the corresponding second touch sensor. The second touch sensor then sends a signal to the controller. The controller restarts the elliptical guide rail to move the clamping plate normally. At the same time, when the first touch sensor is triggered, the two cylinders start again and move the pressure plate to the left. At this time, the serrated spikes mesh with the corresponding gear and drive it to rotate. Then, through meshing, the toothed plate moves to the right, driving the baffle to move to the right in sync. At the same time, under the action of the third spring, the two ejector plates move to the left to eject the sealed sleeve and make it fall into the collection box, completing the qualified product collection process. S5: If the end cap is not qualified, that is, due to the sleeve being too thick or the placement deviation causing the left sealing plate to move too far to the right, the side block cannot reach the second touch sensor. Then the second touch sensor sends a signal to the clamping plate, the clamping plate re-clamps the unqualified sleeve and moves it to the left side of the elliptical guide rail for release, so that it falls into the unqualified collection box.

[0015] Compared with the prior art, the present invention provides a processing apparatus and method for ultrasonic sealing of an insulating heat shrink tubing structure, which has the following beneficial effects: By utilizing the physical properties of low-expansion metal sheets made of tile alloy and high-expansion metal sheets made of nickel alloy, the problem of insufficient pressure in the middle stage of sealing was solved, thus improving the sealing quality. By utilizing the self-reinforcing pressure structure, the ratchet teeth on both sides and the second touch sensor are used to realize the self-detection function of the pipe end, thereby improving the working efficiency of the device. The automatic ejection function of the end-cap sleeve is achieved through the cooperation of the trapezoidal disc, positioning column and ejection plate, which improves the automation of the device and reduces the labor of workers.

[0016] This invention is reasonably designed. Through a pressure self-reinforcing structure, this device overcomes the defect of insufficient pressure when the material softens during the middle stage of sealing due to the constant pressure of the traditional cylinder, and realizes the adaptive adjustment of pressure. Through the sealing self-inspection structure, it realizes the automatic judgment and sorting of the casing sealing quality, the automatic collection of qualified products and the automatic transfer of unqualified products, which significantly reduces the intensity of manual labor and improves the working efficiency of the device.

[0026] In this embodiment, a frame 13 is fixedly connected to the top of the base plate 2, an elliptical guide rail 1 is fixedly connected to the bottom of the frame 13, four clamping plates 12 are slidably connected to the bottom of the elliptical guide rail 1, two controllers 11 are fixedly connected to the top of the elliptical guide rail 1, the two controllers 11 are electrically connected to two second touch sensors 45, two guide plates 23 are fixedly connected to the top of the base plate 2, and the collection frame 24 is slidably connected to the top of the two guide plates 23.

The heat sink 41 is fixedly connected to the top of the right sealing plate 4.

[0028] This invention also provides a method for ultrasonically sealing an insulating heat shrink tubing structure, applied to the aforementioned ultrasonic sealing apparatus for insulating heat shrink tubing structures, comprising the following steps: S1: Set up a defective collection box on the left side of the elliptical guide rail 1, then start the elliptical guide rail 1 and clamping plate 12. The clamping plate 12 clamps the sleeve to be sealed and moves it to the top of the baffle 2603 and then releases it. The device pauses to wait for the sealing operation. Then start the cylinders 22 on both sides to drive the left sealing plate 3 to move to the right. Under the push of the left sealing plate 3, the right side of the sleeve abuts against the left side of the right sealing plate 4 and the inner walls of the top of the sleeve fit together, thus completing the preparation work. S2: Turn on the power supply 42 to start the ultrasonic generator 43. Its high-frequency vibration causes the sleeve contact surface to rub violently and instantly generate local high temperature molten material. At this time, the high temperature generated by the ultrasonic generator 43 is conducted to the second rectangular grooves 35 on both sides through the pressure plate 33, causing the nickel alloy high expansion metal thin plates 3504 on both sides to bend due to heat, which drives the pressure plate 33 to move to the right. Under the condition that the pre pressure remains unchanged, the thickness is reduced due to the melting of the top of the sleeve. The rightward movement of the pressure plate 33 can realize automatic pressure compensation, thereby ensuring that the pressure at the top of the sleeve is sufficient during the sealing process. S3: As the ultrasonic generator 43 continues to work, the temperature rises further. The pressure plate 33 continues to move to the right and enters the sealing mold groove 5. At the same time, the positioning columns 36 on both sides abut against the left side of the corresponding trapezoidal disk 52 and move to the right. This drives the ejector plates 54 on both sides to move to the right until they abut against the inner wall of the corresponding groove 53. At this time, the sleeve is close to the right side of the inner wall of the sealing mold groove 5. When the temperature continues to rise to a certain value, the low expansion metal plates 3503 of the alloy on both sides begin to bend and eventually trigger the first touch sensors 3501 on both sides. This is used as the standard for judging whether the sealing temperature meets the standard. S4: During the sealing process, the left sealing plate 3 drives the loop post 32 to move to the right. The two ends of the loop post 32 abut against the left side of the corresponding side block 44 and push the side block 44 to move to the right. At this time, the serrated spikes 4403 at the bottom of the side block 44 are not engaged with the gear 46. If the sealing is qualified, at the standard sealing temperature, the movement of the left sealing plate 3 will cause the two side blocks 44 to abut against the left side of the corresponding second touch sensor 45. The second touch sensor 45 then sends a signal to the controller 11, and the controller 11 restarts the elliptical guide rail 1 to drive the... The clamping plate 11 moves normally. At the same time, when the first touch sensor 3501 is triggered, the cylinders 22 on both sides start again and drive the pressure plate 33 to move to the left. At this time, the serrated 4403 meshes with the corresponding gear 46 and drives it to rotate. Then, through the meshing connection, the toothed plate 2601 moves to the right, driving the baffle 2603 to move to the right in sync. At the same time, under the action of the third spring 55, the ejector plates 54 on both sides move to the left to push out the sleeve with the end sealed, so that it falls into the collection frame 24, completing the qualified product collection process. S5: If the end cap is not qualified, that is, due to the sleeve being too thick or the placement deviation causing the left sealing plate 3 to move too far to the right, the side block 44 cannot reach the second touch sensor 45, then the second touch sensor 45 sends a signal to the clamping plate 12, the clamping plate 12 re-clamps the unqualified sleeve and moves it to the left side of the elliptical guide rail 1 to release it, so that it falls into the unqualified collection box.

[0029] In the specific implementation of this embodiment, firstly, a defective collection box is set on the left side of the elliptical guide rail 1. Then, the elliptical guide rail 1 and the clamping plate 12 are started. The clamping plate 12 clamps the sleeve to be sealed and moves it to the top of the baffle 2603, and then releases it. The device pauses to await the sealing operation. Next, the cylinders 22 on both sides are started to drive the left sealing plate 3 to move to the right. Under the push of the left sealing plate 3, the right side of the sleeve abuts against the left side of the right sealing plate 4, and the inner walls of the top of the sleeve are put into contact with each other, thus completing the preparation work. Then, the power supply 42 is turned on to start the ultrasonic generator 43. Its high-frequency vibration causes the sleeve contact surface to rub violently and instantly generates local high temperature melting material. At this time, the high temperature generated by the ultrasonic generator 43 is conducted to the second cylinders on both sides through the pressure plate 33. Within the groove 35, the high-expansion nickel alloy thin metal plates 3504 on both sides are heated and bent, causing the pressure plate 33 to move to the right. With the pre-pressure remaining constant, the thickness of the sleeve decreases due to melting at the top. The rightward movement of the pressure plate 33 enables automatic pressure compensation, ensuring sufficient pressure at the top of the sleeve during the sealing process. As the ultrasonic generator 43 continues to operate, the temperature further increases, and the pressure plate 33 continues to move to the right and enters the sealing mold groove 5. Simultaneously, the positioning posts 36 on both sides abut against the left side of the corresponding trapezoidal disk 52 and move to the right, driving the ejector plates 54 on both sides to move synchronously to the right until they abut against the inner wall of the corresponding groove 53. At this point, the sleeve is tightly against the right side of the inner wall of the sealing mold groove 5. When the temperature continues to rise to a certain value, the low-expansion nickel alloy thin plates 3504 on both sides... The thin metal plate 3503 begins to bend and eventually triggers the first touch sensors 3501 on both sides, which serves as the criterion for determining whether the sealing temperature meets the standard. During the sealing process, the left sealing plate 3 drives the loop post 32 to move to the right. The two ends of the loop post 32 abut against the left side of the corresponding side block 44 and push the side block 44 to move to the right. At this time, the spikes 4403 at the bottom of the side block 44 are not engaged with the gear 46. If the sealing is qualified, the movement of the left sealing plate 3 at the standard sealing temperature will cause the two side blocks 44 to abut against the left side of the corresponding second touch sensor 45. The second touch sensor 45 then sends a signal to the controller 11. The controller 11 restarts the elliptical guide rail 1 to drive the clamping plate 11 to move normally. At the same time, when the first touch sensor 3501 is triggered, the two cylinders 2 2. Restart and drive the pressure plate 33 to move to the left. At this time, the serrated 4403 meshes with the corresponding gear 46 and drives it to rotate. Then, through the meshing connection, the toothed plate 2601 moves to the right, driving the baffle 2603 to move to the right in sync. At the same time, under the action of the third spring 55, the two side ejector plates 54 move to the left to push out the sleeve with the sealed end, so that it falls into the collection box 24, completing the qualified product collection process. If the sealing end is unqualified, that is, because the sleeve is too thick or the placement deviation causes the left sealing plate 3 to move to the right too far, the side block 44 cannot reach the second touch sensor 45. Then the second touch sensor 45 sends a signal to the clamping plate 12. The clamping plate 12 re-clamps the unqualified sleeve and moves it to the left side of the elliptical guide rail 1 to release it, so that it falls into the unqualified collection box.Through its pressure-self-reinforcing structure, this device overcomes the defect of insufficient pressure during the middle stage of sealing, which may result in material softening due to constant cylinder pressure in traditional methods, thus achieving adaptive pressure adjustment. Through its self-inspection structure, it achieves automatic judgment and sorting of sleeve sealing quality, automatically collecting qualified products and automatically transferring unqualified products, significantly reducing manual labor intensity and improving device efficiency.

8. A method for ultrasonically sealing an insulating heat-shrinkable tubing structure, applied to the ultrasonic sealing apparatus for the insulating heat-shrinkable tubing structure as described in claim 7, characterized in that... Includes the following steps: S1: Set up a defective collection box on the left side of the elliptical guide rail, then start the elliptical guide rail and clamping plate. The clamping plate clamps the sleeve to be sealed and moves it to the top of the baffle before releasing it. The device pauses the sealing operation. Then start the cylinders on both sides to drive the left sealing plate to move to the right. Under the push of the left sealing plate, the right side of the sleeve abuts against the left side of the right sealing plate and the inner walls of the top of the sleeve fit together, thus completing the preparation work. S2: Turn on the power to start the ultrasonic generator. Its high-frequency vibration causes intense friction on the sleeve contact surface and instantly generates local high-temperature molten material. At this time, the high temperature generated by the ultrasonic generator is conducted to the second rectangular grooves on both sides through the pressure plate, causing the nickel alloy high expansion metal plates on both sides to bend due to heat, which drives the pressure plate to move to the right. Under the condition that the pre-pressure remains unchanged, the thickness of the sleeve is reduced due to the melting at the top of the sleeve. The rightward movement of the pressure plate can achieve automatic pressure compensation, thereby ensuring that the pressure at the top of the sleeve is sufficient during the sealing process. S3: As the ultrasonic generator continues to work, the temperature rises further. The pressure plate continues to move to the right and enters the sealing mold groove. At the same time, the positioning columns on both sides abut against the left side of the corresponding trapezoidal plate and move to the right. This drives the ejector plates on both sides to move to the right until they abut against the inner wall of the corresponding groove. At this time, the sleeve is close to the right side of the inner wall of the sealing mold groove. When the temperature continues to rise to a certain value, the low expansion metal plates of the tile alloy on both sides begin to bend and eventually trigger the first touch sensors on both sides. This is used as the criterion for determining whether the sealing temperature meets the standard. S4: During the sealing process, the left sealing plate moves the spiral column to the right. The two ends of the spiral column abut against the left side of the corresponding side block and push the side block to the right. At this time, the serrated spikes at the bottom of the side block are not engaged with the gear. If the sealing is qualified, the movement of the left sealing plate at the standard sealing temperature will cause the two side blocks to abut against the left side of the corresponding second touch sensor. The second touch sensor then sends a signal to the controller. The controller restarts the elliptical guide rail to move the clamping plate normally. At the same time, when the first touch sensor is triggered, the two cylinders start again and move the pressure plate to the left. At this time, the serrated spikes mesh with the corresponding gear and drive it to rotate. Then, through meshing, the toothed plate moves to the right, driving the baffle to move to the right in sync. At the same time, under the action of the third spring, the two ejector plates move to the left to eject the sealed sleeve and make it fall into the collection box, completing the qualified product collection process. S5: If the end cap is not qualified, that is, due to the sleeve being too thick or the placement deviation causing the left sealing plate to move too far to the right, the side block cannot reach the second touch sensor. Then the second touch sensor sends a signal to the clamping plate, the clamping plate re-clamps the unqualified sleeve and moves it to the left side of the elliptical guide rail for release, so that it falls into the unqualified collection box.
