Description

Technical Field

[0001] This invention relates to a cable management and cutting technique for flexible SC single-core optical fiber, specifically to a fiber optic patch cord straightening and cutting device for use in a free state. Background Technology

[0002] In the era of the Internet, fiber optic patch cords are widely used as tools for network information transmission, leading to increased production demand. To meet this demand, standardized mechanized production of fiber optic patch cords is necessary. The quality of the end-cutting of the fiber optic cable in the initial production stage directly affects the processing quality of subsequent processes. The unpredictable spatial orientation and tendency to sway of the flexible fiber optic cable in its freely suspended state make stable positioning during processing difficult, impacting the mechanization and consistency of subsequent steps. Existing cable handling and cutting technologies mainly employ roller feeding, manual cutting, and fixed-point cutting. Roller feeding relies heavily on manual loading; while fixed-point cutting can guarantee a certain cutting quality, it usually requires additional clamping or complex loading and positioning structures, making it difficult to achieve rapid automatic positioning in a suspended state; manual operation is inefficient and susceptible to human error, resulting in poor cutting consistency. Furthermore, the surface of fiber optic cables is easily damaged; traditional rigid clamping or overpressure feeding methods may cause scratches or micro-bending damage, further affecting product quality.

[0003] Therefore, there is an urgent need for an automatic positioning and cutting device for cables in a free-hanging state: on the one hand, it can use gravity introduction and positioning structure to achieve rapid positioning and stable alignment of the cable; on the other hand, without adding complex secondary clamping, it can achieve cable posture correction through flexible force limiting straightening and tension holding, and cooperate with a high-precision cutting mechanism to complete reliable end cutting, so as to improve cutting accuracy and automated production efficiency. Summary of the Invention

[0007] Further, the cable straightening assembly (2) includes a belt module (201), a motor (202), a motor mount (203), a coupling (204), a module base (205), a slide module connecting plate (206), a slide cylinder (207), pneumatic fingers (208), cable straightening grippers (209), a gripper mounting plate (210), a gripper track connecting plate (211), a linear slide rail (212), a slide rail support plate (213), a support slide connecting block (214), a pen-shaped cylinder (215), a pen-shaped cylinder support (216), and an outer sheath plate. Gold (217); The extended shaft of the belt module (201) is connected to the output shaft of the motor (202) through a coupling (204). The motor (202) is fixed relative to the belt module (201) through a motor mount (203). The motor mount (203), coupling (204), and motor (202) are installed in sequence in the direction of the extended shaft of the belt module (201) to ensure the power transmission of the motor (202) and thus drive the belt module (201) to work; The slide cylinder (207) is connected to the module sliding block through the slide module connecting plate (206). The top of the slide... The part is connected to the slide rail bracket plate (213) via the bracket slide connecting block (214). The extension direction of the slide rail bracket plate (213) is perpendicular to the sliding block direction of the belt module (201) and faces the belt module (201). A linear slide rail (212), a pneumatic gripper track connecting plate (211), a pneumatic gripper mounting plate (210), a pneumatic finger (208), and a wire-straightening gripper (209) are installed sequentially on the slide rail bracket plate (213). The pen-shaped cylinder (215) is fixed on the slide rail bracket plate (213) via a pen-shaped cylinder bracket (216) and is located on the linear slide rail (213). 212) On the side away from the edge line, the push rod of the pen-shaped cylinder (215) and the air gripper track connecting plate (211) are installed on the side perpendicular to the slide rail plane. The pen-shaped cylinder (215) adjusts the horizontal position of the air gripper track connecting plate (211) by pushing the rod. The cable straightening gripper (209) is made of flexible and smooth material and maintains a preset clamping gap g when clamping the cable to form a force-limiting semi-clamping state. This allows the cable to slowly slide relative to the gripper under its own weight and the tensioning action of the gathering component (4) while being clamped by the gripper, thereby realizing the vertical straightening and posture correction of the freely suspended cable.

[0008] Furthermore, the receiving assembly (4) includes a drive wheel (402), a driven wheel (401), a driven wheel drive module (403), a drive wheel drive module (404), a drive wheel power module (405), and a drive shaft (406). The drive wheel (402) and the driven wheel (401) are at the same height and their sides are flush. The drive wheel (402) is fixed to the inside of the drive wheel drive module (404) via the drive shaft (406). (405) is installed on the outside of the drive wheel push module (404) and connected to the extended part of the drive shaft (406); the driven wheel (401) is installed at the outermost end of the driven wheel push module (403) in the pushing direction; the driven wheel (401) and the drive wheel (402) are respectively connected to the drive wheel push module (404) and the frame (6) through the driven wheel push module (403); the axes of the drive wheel (402) and the driven wheel (401) are parallel and the wheel surface distance is adjustable. Among them, the driven wheel push module (403) is a loading push module, which is used to provide adjustable clamping force to the driven wheel (401), so that the drive wheel (402) and the driven wheel (401) clamp the cable and form a stable tension on the cable and realize the lossless cable delivery. The drive wheel power module (405) supports intermittent jogging and positioning holding so that the cable remains in a tense and static state during the cutting process.

[0009] Furthermore, the cutting device (5) includes a tungsten carbide blade (501), a blade power module (502), a cutter extension module (503), and a sliding cutter groove (504). The tungsten carbide blade (501) is composed of a moving blade and a fixed blade in pairs. The fixed blade is fixed on the lower side of the cutter groove, and the moving blade is located between the upper surface of the fixed blade and the inner surface of the sliding cutter groove (504). The extended part of the moving blade is connected to the blade power module (502). The blade power module (502), the sliding cutter groove (504), and the tungsten carbide blade (501) are all installed above the cutter extension module (503). The sliding cutter groove (504) is provided with a side-opening cutting window, which allows the vertically suspended cable to enter from the side and be cut at the cutting window (5041). The sliding cutter groove (504) and the outer side of the moving blade are fitted and guided, so that the moving blade slides and cuts in the sliding cutter groove (504) in a direction perpendicular to the cable axis, thereby reducing the gap between the moving and fixed blades and improving the cutting collinearity. During the cutting process, the cable forms a vertical straight segment under the positioning of the blocking component (1) and the tensioning action of the gathering component (4). The cutting component (5) extends to the vertical straight segment to complete the cutting.

[0010] Furthermore, the cable guiding assembly (3) includes a guide rail (301) and a guide adjustment plate (302).

[0011] Furthermore, the lower surface of the aforementioned finger baffle (104) is in contact with the upper surface of the guide rail (301); when the three-axis cylinder (101) remains extended, the finger baffle (104) can cover the outlet of the guide rail (301), and when the three-axis cylinder (101) retracts, it releases the outlet of the guide rail (301); the cable sliding along the guide rail completes the first point positioning at the blocking component (1).

[0012] Furthermore, the cable straightening assembly (2) is mounted on the same profile protruding frame as the blocking assembly (1) and installed on the opposite side of the blocking assembly (1) to ensure that the opening of the cable straightening clamp (209) is directly below the blocked area and close to the track after the cable straightening clamp (209) extends. The cable straightening clamp (209) is made of flexible and smooth material and is set with a preset clamping gap to form a force-limiting semi-clamping state. After the cable straightening assembly (2) grabs the cable, it does not fully clamp it in the force-limiting semi-clamping state and straightens the cable vertically downward.

[0013] The beneficial effects of this invention are: 1) This invention employs a two-point pickup method, picking up the second positioning point based on the first positioning point. The grippers are made of a flexible and smooth material to ensure that the cable surface is not damaged during the gripping and straightening process, solving the problem of difficulty in picking up cables with uncertain spatial orientation in a free state. This provides conditions for automated processing and automated positioning. 2) This invention uses a compression roller feeding method to organize the cable. The rubber surface of the roller provides sufficient friction and greatly reduces damage to the cable surface. Stable tension is achieved through elastic loading of the driven roller, and combined with intermittent jogging and positioning holding, the cable tension remains stationary at the moment of cutting. Furthermore, by adding a sensor to control the roller retraction time, the cutting position can be freely selected within a certain range. 3) This invention employs a sliding cutting method, using a grinding process to allow the blade to slide within the blade groove, thus solving the problems of excessive gaps between blades and non-collinear cutting directions. Simultaneously, it utilizes blocking positioning and tensioning to form a vertical straight segment, achieving cutting without secondary clamping. This increases cutting accuracy and improves the cutting quality of optical fiber cables. 4) The device of the present invention has a simple structure, is easy to disassemble and assemble, and has reserved a sensor installation position, which can realize automated and efficient production and reduce energy consumption in the production process.

[0024] As a preferred embodiment of the present invention, such as Figure 3As shown, the cable straightening assembly (2) includes a belt module (201), a motor (202), a motor mount (203), a coupling (204), a module base (205), a slide module connecting plate (206), a slide cylinder (207), pneumatic fingers (208), cable straightening grippers (209), a gripper mounting plate (210), a gripper rail connecting plate (211), a linear slide rail (212), a slide rail bracket plate (213), a bracket slide connecting block (214), a pen-shaped cylinder (215), a pen-shaped cylinder bracket (216), and an outer sheet metal casing (2). 17); The extended shaft of the belt module (201) is connected to the output shaft of the motor (202) via a coupling (204). The motor (202) is fixed relative to the belt module (201) via a motor mount (203). The motor mount (203), coupling (204), and motor (202) are installed sequentially in the direction of the extended shaft of the belt module (201) to ensure power transmission of the motor (202) and drive the belt module (201) to work.

[0025] As a preferred embodiment of the present invention, such as Figure 4As shown, the receiving assembly (4) includes a drive wheel (402), a driven wheel (401), a driven wheel push module (403), a drive wheel push module (404), a drive wheel power module (405), and a drive shaft (406). The drive wheel (402) and the driven wheel (401) are at the same height and their sides are flush. The drive wheel (402) is fixed to the inside of the drive wheel push module (404) through the drive shaft (406). The drive wheel power module (405) is installed on the outside of the drive wheel push module (404) and is connected to the extended part of the drive shaft (406). The driven wheel (401) is installed at the outermost end of the driven wheel push module (403) in the pushing direction. The driven wheel (401) and the drive wheel (402) are respectively connected to the drive wheel push module (404) and the frame (6) through the driven wheel push module (403). The axes of the drive wheel (402) and the driven wheel (401) are parallel and the wheel surface spacing is adjustable. The driven wheel push module (403) is a loading push module used to provide adjustable clamping force to the driven wheel (401), so that the driving wheel (402) and the driven wheel (401) clamp the cable and form a stable tension on the cable and achieve non-destructive cable delivery. The driving wheel power module (405) supports intermittent jogging and positioning to keep the cable taut and stationary during the cutting process.

[0026] As a preferred embodiment of the present invention, such as Figure 5 and Figure 6 As shown, the cutting device (5) includes a tungsten carbide blade (501), a blade power module (502), a cutter extension module (503), and a sliding cutter groove (504).

The extended part of the moving blade is connected to the blade power module (502). The blade power module (502), the sliding cutter groove (504), and the tungsten carbide blade (501) are all installed above the cutter extension module (503). The sliding cutter groove (504) is provided with a side-opening cutting window, which allows the vertically suspended cable to enter from the side and be cut at the cutting window (5041). The sliding cutter groove (504) and the outer side of the moving blade are fitted and guided, so that the moving blade slides and cuts in the sliding cutter groove (504) in a direction perpendicular to the cable axis, thereby reducing the gap between the moving and fixed blades and improving the cutting collinearity. During the cutting process, the cable forms a vertical straight segment under the positioning of the blocking component (1) and the tensioning action of the gathering component (4). The cutting component (5) extends to the vertical straight segment to complete the cutting.

[0027] The following description, with reference to images, illustrates the working process of a fiber optic patch cord straightening and cutting device and method for use in a free state.

[0028] like Figure 1 and Figure 7 As shown, the cable guiding assembly (3) includes a guide rail (301) and a guide adjustment plate (302). The guide rail (301) is installed on the extended support portion of the aluminum profile frame (6) via the guide adjustment plate (302), ensuring that the cable reaches the designated position through gravity and relative sliding with the rail during the suspension process. The guide rail (301) is configured as a guide rail to facilitate the cable's downward slide, allowing the cable to slide stably to the outlet end under the action of gravity. The guide adjustment plate (302) is used to adjust the tilt angle and the spatial position of the outlet end, so that the cable outlet end is aligned with the blocking position of the blocking assembly (1), thereby achieving stable introduction and first point positioning.

[0029] like Figure 1 and Figure 2 As shown, the lower surface of the finger baffle (104) in the blocking assembly (1) is in contact with the upper surface of the guide rail (301); when the three-axis cylinder (101) is extended, the finger baffle (104) can cover the outlet of the guide rail (301), and the outlet is released when the three-axis cylinder (101) retracts; the cable sliding along the guide rail completes the first point positioning at the blocking assembly (1).

[0030] like Figure 1 and Figure 4 As shown, the drive wheel (402) and driven wheel (401) of the receiving assembly (4) are kept at the same height and flush on the sides. The cable is driven to move by rolling after being clamped by the rubber wheel. The driven wheel push module (403) is an elastic loading push module used to provide adjustable clamping force so that the cable is stably tensioned under the clamping of the two wheels; when the cutting action is performed, the drive wheel power module (405) can stop and hold, so that the cable is cut in a tensioned and static state, thereby improving the cutting consistency.

[0031] like Figure 1 and Figure 3 As shown, the cable straightening assembly (2) is mounted on the same aluminum profile extending from the blocking assembly (1) on the opposite side of the blocking assembly (1). This ensures that the opening of the cable straightening gripper (209) is directly below the blocked area and close to the track after it extends. The cable straightening gripper (209) is made of a flexible and smooth material. When gripping the cable, it maintains a preset clamping gap to form a force-limiting semi-clamping state, allowing the cable to slowly slide relative to the gripper under its own weight and the tensioning action of the retrieval assembly (4), thereby achieving vertical straightening and posture correction of the cable and avoiding squeezing damage to the cable surface. After gripping the cable, the cable straightening assembly (2) does not fully clamp it but straightens the cable vertically downwards.

[0032] like Figure 5 and Figure 6As shown, the cutting module is extended, and the cutter is made of tungsten steel. The openings on the side of the cutter and the cutter groove ensure that the vertical cable is centered on the cutter when the cutting assembly (5) is extended. The sliding cutter groove (504) and the outer side of the moving blade are fitted and guided, so that the moving blade slides and cuts in the sliding cutter groove (504) in a direction perpendicular to the cable axis, thereby reducing the gap between the moving and fixed blades and improving the cutting collinearity. During cutting, the cable forms a vertical straight segment under the positioning of the blocking assembly (1) and the tensioning and holding action of the gathering assembly (4), and precision cutting can be completed without additional secondary clamping. The cutter retracts after cutting.

[0033] The present invention and its embodiments have been described above, but are not intended to limit the present invention. For those skilled in the art, any design, modification, substitution, etc., made within the spirit and principles of the present invention shall be within the protection scope of the present invention.
