Description

Technical Field

[0001] This invention relates to the field of optical fiber thermal stripping equipment technology, and in particular to an automatic pressure release mechanism for use in an automatic optical fiber thermal stripping machine. Background Technology

[0002] A fiber optic thermal stripper is a specialized piece of equipment used for processing fiber optic communication cables. It uses precisely controlled heating elements to locally soften the polymer coating on the outer surface of the optical fiber, and then uses mechanical pulling or stripping mechanisms to cleanly and non-destructively peel off the softened coating, exposing the pure glass fiber core. This prepares the fiber for subsequent operations such as fiber optic splicing and connector assembly. Its core advantage lies in its ability to achieve efficient, precise, and non-damaging stripping of the fiber itself, making it a crucial tool in fiber optic production, installation, and maintenance.

[0003] However, existing equipment often encounters the following problems during use:

[0004] Traditional thermal stripping machines use a strong magnetic force to keep the heating cover closed, ensuring stability during thermal stripping. Operators (especially female workers) must repeatedly and forcefully overcome this powerful magnetic force to open the cover to replace the optical fiber. However, because this replacement operation is a continuous process, this repetitive and high-intensity movement easily leads to muscle fatigue, soreness, and even occupational injuries (such as carpal tunnel syndrome) for operators. Furthermore, as employee fatigue increases, the operating speed slows down, affecting overall production efficiency and potentially impacting product quality due to improper operation. Summary of the Invention

[0005] The main objective of this invention is to provide an automatic pressure release mechanism for an automatic optical fiber thermal stripping machine. This effectively solves the problem mentioned in the background art where the heating cover of a conventional thermal stripping machine is closed by strong magnetic attraction to ensure stability during thermal stripping. Operators need to repeatedly and forcefully overcome this powerful magnetic force to open the cover to replace the optical fiber. However, since this replacement operation is a continuous process, this repetitive, high-intensity action easily leads to muscle fatigue, soreness, and even occupational injuries for the operator. Simultaneously, as employee fatigue increases, the operating speed slows down, affecting overall production efficiency and potentially impacting product quality due to improper operation. This invention addresses this issue by converting the rotational motion of the drive motor into the linear motion of the top block. Utilizing the interaction between the inclined surface of the top block and the inclined side wheel surface at the bottom of the top rod, the horizontal thrust is converted into a vertical lifting force, overcoming the spring pressure and opening the heating cover. This breaks the attraction between the magnet and the suction block, achieving automatic pressure release. The operator now only needs to apply a small force to open the cover after the mechanism has opened it and the magnetic force has essentially disappeared. The effort of "lifting with force" has been transformed into "breaking easily," resulting in a significant decrease in labor intensity.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] An automatic pressure release mechanism for use in an automatic optical fiber thermal stripping machine includes:

[0008] Base;

[0009] A lead screw, which is arranged laterally inside the base, with one end of the lead screw fixedly connected to the inner wall of the base;

[0010] A sliding seat, which is sleeved on the lead screw;

[0011] A force-relieving rod, one end of which is fixedly connected to one end of the sliding seat;

[0012] A top block is mounted on the end of the force-relieving rod away from the sliding seat;

[0013] A beveled surface is formed on the top block;

[0014] A heating base, wherein the heating base is mounted on top of the base;

[0015] A top rod, the top end of which is vertically inserted into the heating base, and the bottom end of which extends into the base.

[0016] Also includes:

[0017] A motor mount is fixedly installed inside the base, and the force-relieving rod passes through one end of the motor mount;

[0018] A drive motor is fixedly mounted on the motor base, and the other end of the lead screw is connected to the output end of the drive motor.

[0019] A heating cover, which is hinged to the heating base via a hinge;

[0020] The reset cavity is provided inside the heating base;

[0021] The top rod has an outwardly flared flange on its shaft;

[0022] A compression spring is sleeved on the top rod and housed within the reset cavity. The top end of the compression spring abuts against the inner top wall of the reset cavity, and its bottom end abuts against the flange.

[0023] The suction block is mounted on the heating base;

[0024] A sliding rod, the bottom end of which is fixedly connected to the other end of the sliding seat, and the top end of which passes through the base;

[0025] An optical fiber clamp, the bottom end of which is connected to a sliding seat via a slide rod.

[0026] The axial direction of the lead screw intersects the extension direction of the sliding seat.

[0027] The top block is located below the top rod.

[0028] The heating cover is equipped with a magnet corresponding to the position of the suction block.

[0029] The bottom end of the push rod is on the sliding axis of the oblique section.

[0030] The axial direction of the lead screw is parallel to the extension direction of the force-relieving rod.

[0031] The bottom end of the top rod is an inverted conical structure.

[0032] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention converts the rotational motion of the drive motor into the linear motion of the top block. Utilizing the interaction between the inclined surface of the top block and the inclined wheel surface at the bottom of the push rod, the horizontal thrust is converted into a vertical lifting force, overcoming the spring pressure and opening the heating cover. This breaks the adhesion between the magnet and the suction block, achieving automatic force release. The operator now only needs to apply a very small force after the mechanism has opened the heating cover and the magnetic force has essentially disappeared to complete the opening action. It transforms "forcefully lifting" into "easily prying," resulting in an order-of-magnitude reduction in labor intensity. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0041] like Figure 1-4 As shown, the present invention provides an automatic pressure release mechanism for an automatic optical fiber thermal stripping machine, the automatic pressure release mechanism for the automatic optical fiber thermal stripping machine comprising:

[0042] The lead screw 2 is arranged laterally inside the base 1, with one end fixedly connected to the inner wall of the base 1. The axial direction of the lead screw 2 intersects the extension direction of the sliding seat 3, and the axial direction of the lead screw 2 is parallel to the extension direction of the relief rod 4. The sliding seat 3 is sleeved on the lead screw 2, ensuring the smooth operation of the entire system. The design of the sliding seat 3 ensures stability under different working conditions and can withstand pressure and force to drive the movement of the relief rod 4 and other related components. One end of the relief rod 4 is fixedly connected to one end of the sliding seat 3, and its body passes through one end of the motor base 9. The top block 5 is installed at the end of the relief rod 4 away from the sliding seat 3; the top block 5 is located below the top rod 8. The purpose of the relief rod 4 is to transmit force through the movement of the sliding seat 3, driving the top block 5 and the top rod 8 to rise and fall, thus controlling the lifting operation.

[0043] In this invention, the beveled surface 6 is formed on the top block 5; the bottom end of the push rod is on the sliding axis of the beveled surface, the heating base 7 is installed above the base 1, the top end of the push rod 8 is vertically inserted into the heating base 7, and the bottom end of the push rod 8 extends into the base 1. The bottom end of the push rod 8 has an inverted conical structure. The design of the beveled surface 6 of the top block 5 reduces the contact friction between it and the push rod 8, thus reducing wear. The function of the top block 5 is to convert the horizontal thrust into a vertical lifting force by contacting the beveled surface 6 of the push rod 8, pushing the push rod 8 to overcome the pressure of the compression spring 14 and move upward.

[0044] In this invention, the motor base 9 is fixedly installed inside the base 1, the drive motor 10 is fixedly installed on the motor base 9, the other end of the lead screw 2 is connected to the output end of the drive motor 10, and the heating cover 11 is hinged to the heating base 7 via a hinge. A magnet corresponding to the position of the suction block 15 is installed on the heating cover 11. The heating cover 11 can be tightly closed by the attraction between the magnet and the suction block 15, ensuring that the heating cover 11 remains stable during the heat stripping process and effectively heats the optical fiber. A reset cavity 12 is provided inside the heating base 7, and the top rod 8 has an outwardly expanding flange 13. This outwardly expanding flange 13 is wider than the diameter of the top rod 8, ensuring that the top rod 8 will not fall naturally into the base 1.

[0045] In this invention, a compression spring 14 is sleeved on the top rod 8 and housed within the reset cavity 12. The top end of the compression spring 14 abuts against the inner top wall of the reset cavity 12, and its bottom end abuts against the flange 13. As a reset element, when the top block 5 separates from the top rod 8, the elastic force of the compression spring 14 ensures that the top rod 8 can quickly reset to its initial position. This design reduces the labor intensity of operators and reduces mechanical wear. A suction block 15 is installed on the heating base 7; the bottom end of the slide rod 16 is fixedly connected to the other end of the sliding seat 3, and the top end of the slide rod 16 passes through the base 1. The bottom end of the fiber optic clamp 17 is connected to the sliding seat 3 through the slide rod 16.

[0046] In this invention, the bottom end of the top rod 8 is an inverted cone with an inclined wheel surface made of copper. The top block 5 is made of iron, and both are smooth inclined surfaces. The contact between copper and iron results in minimal friction, reducing wear and tear. Experiments show it can be reused 500,000 times, approaching the lifespan of a hot stripper. This 500,000-cycle lifespan, close to the equipment's lifespan, signifies a "one-and-done" solution requiring almost no maintenance, thus increasing the overall reliability and value of the equipment.

[0047] It is worth noting that the bottom end of the fiber optic clamp 17 is connected to one end of the sliding seat 3 via the slide rod 16. Therefore, when the sliding seat 3 is driven away from the drive motor 10, the fiber optic clamp 17 will be driven to slide axially. The sliding fiber optic clamp 17 will pull out the heat-stripped fiber to complete the heat stripping. At the same time, the force-releasing rod 4 connected to the other end of the sliding seat 3 will also be driven to make the top block 5 lift the top rod 8 to complete the lifting work. The two are carried out almost simultaneously, which greatly improves the work efficiency.

[0048] It should be noted that, in the automatic pressure release mechanism for an automatic optical fiber thermal stripping machine of the present invention, the drive motor 10 is stationary in the initial closed state. The sliding seat 3 is located at the rightmost end of the lead screw 2, close to the drive motor 10. The top block 5 and the top rod 8 are separated and not in contact. The top rod 8 is pressed down to its lowest point under the elastic force of the compression spring 14. The heating cover 11 is tightly closed under the strong attraction of the magnet and the suction block 15, and is in a ready state for thermal stripping. At this time, the drive motor 10 starts and drives the lead screw 2 to rotate forward. The rotation of the lead screw 2 drives the sliding seat 3 to move horizontally to the left away from the drive motor 10. This causes the sliding seat 3 to slide axially on the body of the lead screw 2. One end of the sliding seat 3 is fixedly fitted with a pressure release rod 4, and the sliding seat 3 drives the top block 5 to move synchronously to the left through the pressure release rod 4. The beveled surface 6 of the top block 5 begins to contact the conical beveled wheel surface at the bottom end of the top rod 8. As the top block 5 continues to advance, the two inclined planes slide relative to each other, and the horizontal thrust of the top block 5 is converted into a vertical upward lifting force, pushing the top rod 8 to overcome the pressure of the compression spring 14 and move upward. The sliding seat 3 moves to the leftmost end of the stroke of the lead screw 2. At this time, the top block 5 lifts the top rod 8 to its highest point. The top of the top rod 8 opens the heating cover 11, completely separating the magnet from the suction block 15, and the attraction force between them is drastically reduced to almost zero. At this time, the operator can easily lift the heating cover 11 with minimal force, only needing to overcome the hinge resistance, to complete the picking, placing, and replacing of the optical fiber, greatly reducing labor intensity. After replacing the optical fiber, the drive motor 10 rotates in the opposite direction, and the lead screw 2 drives the sliding seat 3 to move horizontally to the right in the direction of the drive motor 10, at which point the top block 5 separates from the top rod 8 and retracts. Once the top rod 8 loses the support of the top block 5, it quickly moves down and resets under the elastic force of the compression spring 14. The operator closes the heating cover 11, which automatically closes under the attraction of the magnet and the suction block 15 and locks to the maximum suction state, waiting for the next hot stripping operation.
