Description

Technical Field

[0001] This invention relates to the field of optical fiber manufacturing technology, specifically to an optical fiber winding film device. Background Technology

[0002] Optical fiber is a light transmission tool that utilizes the principle of total internal reflection of light within fibers made of glass or plastic. With the rapid development of my country's economy, the use of optical fiber is increasing daily, and the communications industry is placing increasingly higher demands on its quality. During the production process, optical fibers are typically packaged on standard plastic discs. The fibers are wound onto these discs, with different disc sizes used depending on the fiber length. Due to the inherent characteristics of optical fiber, to prevent damage during transportation and to avoid exposure to sunlight or dust contamination, one or more layers of protective film are usually wrapped around the outermost layer of the fiber on the disc. The width of the protective film is the same as the width of the disc.

[0003] The process of coating fiber optic reels with a wrapping film is typically done manually. Due to the large number of fiber optic reels, the wrapping work is enormous, and manual wrapping is slow, inefficient, and costly. Furthermore, human hands handling the fiber can easily damage it, resulting in poor film consistency. Existing wrapping mechanisms have the following problems: First, current wrapping equipment is only suitable for wrapping fiber optic reels of one size. Second, current wrapping equipment tends to stack the wrapping film during the wrapping process, resulting in unevenness, inconsistent coverage of the fiber surface, and slippage, leading to wrapping failures and a low success rate. Third, current wrapping equipment lacks dust removal capabilities. Summary of the Invention

[0004] To address the issue that the aforementioned film-winding equipment is only applicable to one type of fiber optic disc, this invention provides a fiber optic disc film-winding device. The clamping mechanism of the fiber optic disc film-winding device can clamp the fiber optic disc and move it vertically. It is applicable to fiber optic discs of various diameters and can automatically prepare, wind, and cut the film without manual intervention. It can automatically connect with front-end and back-end processes to achieve film winding of fiber optic discs of various specifications.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] An optical fiber winding film device, comprising:

[0007] The film winding mechanism includes a left roller arm, a right roller arm, and a roller arm opening and closing assembly. The left and right roller arms are arranged side by side. The roller arm opening and closing assembly can open or close the left and right roller arms. When both the left and right roller arms are open, the fiber optic disk can enter between the left and right roller arms. When both the left and right roller arms are closed, the left and right roller arms form a ring and can encircle the fiber optic disk.

[0008] The clamping mechanism includes a front clamping component and a rear clamping component arranged in front and behind. The front clamping component includes a front clamping plate, and the rear clamping component includes a rear clamping plate. The front and rear clamping plates can clamp the fiber optic disc, and the front and rear clamping plates can also move the fiber optic disc in the vertical direction. The clamping mechanism can also make the fiber optic disc rotate.

[0009] The fiber optic reel delivery mechanism enables the fiber optic reel to move in the left and right directions, and is located below the film winding mechanism.

[0010] A film wrapping frame is used to hold film wrapping trays;

[0011] The film cutting mechanism is capable of cutting the wound film between the winding film frame and the fiber optic disc.

[0012] The beneficial effects of this invention are:

[0048] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0049] An optical fiber winding film device, such as Figures 1 to 4 As shown, it includes:

[0050] The film winding mechanism 1 includes a left roller arm 11, a right roller arm 12, and a roller arm opening and closing assembly 13. The left roller arm 11 and the right roller arm 12 are symmetrically arranged. The roller arm opening and closing assembly 13 can open or close the left roller arm 11 and the right roller arm 12. When both the left roller arm 11 and the right roller arm 12 are open, the fiber optic disk 8 can enter between the left roller arm 11 and the right roller arm 12. When both the left roller arm 11 and the right roller arm 12 are closed, the left roller arm 11 and the right roller arm 12 form a ring. The left roller arm 11 and the right roller arm 12 can surround the fiber optic disk 8, and the axis of the fiber optic disk 8 coincides with the axis of the ring.

[0051] The clamping mechanism 2 includes a front clamping component 21 and a rear clamping component 22 arranged at the front and rear. The front clamping component 21 includes a front clamping plate 211, and the rear clamping component 22 includes a rear clamping plate 221. The front clamping plate 211 and the rear clamping plate 221 can clamp and fix the optical fiber disk 8. The front clamping plate 211 and the rear clamping plate 221 can also make the optical fiber disk 8 move in the vertical direction. The clamping mechanism 2 can make the optical fiber disk 8 rotate.

[0052] The fiber optic reel conveying mechanism 3 enables the fiber optic reel 8 to move in the left and right directions. The fiber optic reel conveying mechanism 3 is located below the film winding mechanism 1.

[0053] The film wrapping frame 4 can hold the film wrapping tray 7;

[0054] The film cutting mechanism 5 is capable of cutting the wound film 71 between the wound film frame 4 and the optical fiber disk 8.

[0055] In this embodiment, the upper ends of the left roller arm 11 and the right roller arm 12 are connected by an upper support shaft 14. The upper support shaft 14 extends in the front-back direction. Both the left roller arm 11 and the right roller arm 12 can swing around the upper support shaft 14. When both the left roller arm 11 and the right roller arm 12 are closed, the left roller arm 11 and the right roller arm 12 can surround the fiber optic disk 8 360°.

[0056] In this embodiment, the optical fiber winding film equipment further includes a frame 6, and the winding mechanism 1 also includes a bracket 16. Both the front and rear ends of the upper bracket shaft 14 are fixed to the frame 6 via the bracket 16. The wheel arm opening and closing assembly 13 includes a left opening and closing cylinder 131 and a right opening and closing cylinder 132. The left opening and closing cylinder 131 is correspondingly connected to the left roller arm 11, and the right opening and closing cylinder 132 is correspondingly connected to the right roller arm 12.

[0057] When the piston rod of the left opening / closing cylinder 131 retracts, the lower end of the left roller arm 11 can swing upwards and to the left, moving away from the lower end of the right roller arm 12, and the left roller arm 11 is in the open state. When the piston rod of the left opening / closing cylinder 131 extends, the lower end of the left roller arm 11 can swing downwards and to the right, moving closer to the lower end of the right roller arm 12, and the left roller arm 11 is in the closed state.

[0058] When the piston rod of the right opening / closing cylinder 132 retracts, the lower end of the right roller arm 12 can swing upward and to the right, moving away from the lower end of the left roller arm 11, and the right roller arm 12 is in the open state. When the piston rod of the right opening / closing cylinder 132 extends, the lower end of the right roller arm 12 can swing downward and to the left, moving closer to the lower end of the left roller arm 11, and the right roller arm 12 is in the closed state.

[0059] In this embodiment, the left roller arm 11 includes a plurality of left roller assemblies 111 and two left arm plates 112 spaced apart. The left arm plates 112 have an arc-shaped structure. The plurality of left roller assemblies 111 are arranged at intervals along the circumference of the left arm plates 112. The plurality of left roller assemblies 111 are sequentially moved away from the upper support shaft 14 along the circumference of the left arm plates 112. The left roller assembly 111 includes a left roller 113 and a left roller shaft 114. The plurality of left rollers 113 are sleeved on the left roller shaft 114. The left roller assembly 111 can move along the diametrical direction of the annulus.

[0060] In this embodiment, the left arm plate 112 is provided with a left strip-shaped through hole, which extends radially along the left arm plate 112. The end of the left roller shaft 114 passes through the left strip-shaped through hole on the left arm plate 112. The left arm plate 112 is provided with a left reset assembly 115, which is connected one-to-one with the left roller shaft 114 of the left roller assembly 111. The left reset assembly 115 enables the left roller assembly 111 to move toward the axis of the ring.

[0061] In this embodiment, the right roller arm 12 includes a plurality of right roller assemblies 121 and two right arm plates 122 spaced apart. The right arm plates 122 have an arc-shaped structure. The plurality of right roller assemblies 121 are arranged at intervals along the circumference of the right arm plates 122. The plurality of right roller assemblies 121 are sequentially moved away from the upper support shaft 14 along the circumference of the right arm plates 122. The right roller assembly 121 includes a right roller 123 and a right roller shaft 124. The plurality of right rollers 123 are sleeved on the right roller shaft 124. The right roller assembly 121 can move along the diametrical direction of the ring.

[0062] like Figures 1 to 8 As shown, the right arm plate 122 is provided with a right strip-shaped through hole, which extends radially along the right arm plate 122. The end of the right roller shaft 124 passes through the right strip-shaped through hole on the right arm plate 122. The right arm plate 122 is provided with a right reset assembly 125, which is connected to the right roller shaft 124 of the right roller assembly 121 in a one-to-one correspondence. The right reset assembly 125 enables the right roller assembly 121 to move toward the axis of the ring.

[0063] The right-side reset assembly 125 includes a spring 127 and a spring seat. One end of the spring 127 is connected and fixed to the right arm plate 122 via the spring seat, and the other end of the spring 127 is connected and fixed to the right roller shaft 124. The spring 127 is in a compressed state and is located outside the right roller shaft 124, thus providing a restoring force to the right roller assembly 121 to move toward the axis of the ring.

[0064] The left reset assembly 115 has the same structure as the right reset assembly 125. The left reset assembly 115 provides a restoring force to the left roller assembly 111 to move towards the axis of the ring, and the right reset assembly 125 provides a restoring force to the right roller assembly 121 to move towards the axis of the ring. This allows the left roller arm 11 and the right roller arm 12 to encircle fiber optic discs 8 of various diameters. When encircling fiber optic discs 8 of different diameters, the left roller assembly 111 and the right roller assembly 121 can move within the slotted through-hole according to the outer diameter of the fiber optic disc 8, and the spring ensures that the rollers exert a certain pressure on the fiber optic disc 8.

[0065] like Figures 1 to 8As shown, the rollers (left roller 113 and right roller 123) are made of foam sponge, with moderate hardness and elasticity, which can prevent damage to the optical fiber. The left roller arm 11 consists of 5 left roller assemblies 111 (3 sets of wide rollers and 2 sets of narrow rollers) arranged alternately. The right roller arm 12 consists of 4 right roller assemblies 121 (2 sets of wide rollers and 2 sets of narrow rollers) arranged alternately. A total of 9 sets of rollers can clamp the optical fiber tray 8 around it 360°, and all rollers can be attached to the surface of the optical fiber tray 8. The upper support shaft 14 passes through the upper end of the left arm plate 112 and the upper end of the right arm plate 122.

[0066] The right roller 123 of the uppermost right roller assembly 121 in the right roller arm 12 is in contact with the clamping roller 126 described below, which can fix the head of the wrapping film 71. When the wrapping mechanism 1 clamps the optical fiber disk 8, the right roller 123 of the uppermost right roller assembly 121 in the right roller arm 12 can press the head of the wrapping film 71 onto the surface of the optical fiber disk 8. During the rotation of the optical fiber disk 8, the left roller 113 and the right roller 123 are driven to rotate, and the rollers drive the clamping roller 126 to rotate, forming a traction force on the wrapping film 71. In this way, the wrapping film 71 can be attached to the surface of the optical fiber disk 8 through the rotation of the 9 sets of rollers, so that the wrapping film 71 evenly covers the surface of the optical fiber disk 8.

[0067] Because the axial width of the fiber optic discs 8 varies depending on their specifications, the aforementioned wide-wheel assembly consists of three rollers, designed for different disc sizes. Using one side as a reference, the outer sides of the first two rollers can be fitted against the inner side of the 25km fiber optic disc 8 to achieve film wrapping for smaller discs. Using one side as a reference, the outer sides of the first and third rollers can be fitted against the inner side of the 50km fiber optic disc to achieve film wrapping for larger discs. Since the diameters of the fiber optic discs differ and the length of fiber wound on each type of disc also varies, the film wrapping process must adapt to both the minimum diameter of the smaller disc and the maximum diameter of the larger disc.

[0068] like Figure 10 and Figure 11 As shown, in the clamping mechanism 2, the front clamping assembly 21 includes a front lifting cylinder and a rotary drive unit (such as a servo motor). The front lifting cylinder, the rotary drive unit, and the front clamping plate 211 are connected in sequence. The front lifting cylinder can raise and lower the rotary drive unit and the front clamping plate 211, and the rotary drive unit can make the front clamping plate 211 rotate, thereby driving the fiber optic disc 8 to rotate. The rear clamping assembly 22 includes a rear lifting cylinder, which is connected to the rear clamping plate 221.

[0069] Both the front clamping plate 211 and the rear clamping plate 221 employ a pin design on their clamping surfaces (i.e., the surfaces facing the fiber optic tray 8) for axial positioning of the fiber optic tray 8. The clamping surfaces are coated with polyurethane to increase friction with the fiber optic tray 8. The front clamping plate 211 drives the fiber optic tray 8 to rotate, and the rear clamping plate 221 rotates accordingly. The front and rear clamping plates 211 and 221 can lift the fiber optic tray 8, moving it a certain distance away from the fiber optic tray conveying mechanism 3, facilitating the 360° surround and hold of the fiber optic tray 8 by the roller assembly of the film winding mechanism 1.

[0070] like Figure 9 As shown, the film wrapping frame 4 is located directly above the film wrapping mechanism 1, and there is a gap between the film wrapping frame 4 and the film wrapping mechanism 1. The film wrapping frame 4 includes a film wrapping disc mounting shaft 41, and the film wrapping disc 7 can be sleeved on the film wrapping disc mounting shaft 41. The film wrapping disc mounting shaft 41 is arranged vertically parallel to the upper support shaft 14. A film clamping roller 126 is provided on the right roller arm 12. The front and rear ends of the film clamping roller 126 pass through the upper part of the two right arm plates 122. The upper support shaft 14 and the film clamping roller are connected. The right roller assembly 121, which is parallel to the upper support shaft 14, is the right clamping roller assembly 128. Along the circumference of the right arm plate 122, the clamping roller 126 is located between the upper support shaft 14 and the right clamping roller assembly 128. The clamping roller 126 and the right clamping roller assembly 128 can always clamp the wrapping film 71. The wrapping film 71 on the wrapping film tray 7 can pass between the clamping roller 126 and the right clamping roller assembly 128 and be wrapped around the fiber optic tray 8.

[0071] In this embodiment, the fiber optic tray conveying mechanism 3 includes multiple fiber optic tray holding positions 31, each with a different length and marked with different diameter specifications. For example, different fiber optic tray holding positions 31 can be marked with different colors or numbers on the conveying plate 32. When multiple fiber optic trays 8 of different diameter specifications are placed in their respective fiber optic tray holding positions 31, the axes of the multiple fiber optic trays 8 of different diameter specifications are all at the same height, which facilitates the clamping mechanism 2 in clamping the fiber optic trays 8 of different diameter specifications, thus expanding the applicability of the fiber optic tray winding equipment. In addition, different fiber optic trays 8 in different fiber optic tray holding positions 31 will not affect the clamping mechanism 2 in clamping the fiber optic trays 8.

[0072] like Figure 15As shown, the fiber optic reel conveying mechanism 3 also includes a conveying plate 32 and a conveying roller 33. The fiber optic reel holding position 31 is located between two adjacent conveying rollers 33. The distance between two adjacent conveying rollers 33 is different. By designing the length of the fiber optic reel holding position 31, the axes of the various fiber optic reels 8 with different diameters can be located at the same height. For example, when a 20cm diameter fiber optic reel 8 is located at the first fiber optic reel holding position 31, a 25cm diameter fiber optic reel 8 is located at the second fiber optic reel holding position 31, and a 30cm diameter fiber optic reel 8 is located at the third fiber optic reel holding position 31, the axes of the three fiber optic reels 8 are all located at the same height.

[0073] In this embodiment, the film winding mechanism 1 also includes multiple sets of air knives 15 (i.e., air nozzles). These multiple sets (e.g., three sets) of air knives 15 are arranged circumferentially around the annulus. The blowing direction of the air knives 15 is the tangential direction of the fiber optic disk 8 when the left roller arm 11 and right roller arm 12 encircle it, and the blowing direction of the air knives 15 is the same as the rotation direction of the fiber optic disk 8. The air knives 15 allow for simultaneous blowing and dust removal from the surface of the fiber optic disk 8 while the film is being wound. The air knives 15 also ensure that the wound film adheres tightly to the surface of the fiber optic disk 8, preventing the wound film head from detaching or slipping during the winding process. Furthermore, the air knives 15 ensure that the cut end of the wound film 71 adheres to the surface of the right roller 123.

[0074] like Figures 12 to 14 As shown, the film cutting mechanism 5 includes a heating wire 51, a blade holder 52, and a moving drive unit 53 connected in sequence. The heating wire 51 is located on the right side of the right roller arm 12 and extends in the front-to-back direction. The heating wire 51 is connected to a power source via a wire, and the heating wire 51 can cut the wrapping film 71 by electric heating. The moving drive unit 53 (such as a cylinder) can drive the heating wire 51 and the blade holder 52 to move in the left-to-right direction. In the vertical direction, the heating wire 51 is located between the lower end of the clamping roller 126 and the axis of the annulus. The heating wire 51 of the film cutting mechanism 5 can cut the wrapping film 71 between the clamping roller 126 and the fiber optic disc 8. After the heating wire 51 cuts the wrapping film 71, the head of the wrapping film 71 is still fixed by the clamping roller 126 and the right roller 123 of the right clamping roller assembly 128 in the right roller arm 12, thus achieving film preparation.

[0075] The working process of the fiber optic winding film equipment (also known as: fully automatic fiber optic winding film equipment or fully automatic fiber optic winding film dust removal equipment) is described below.

[0076] 1. Both the left roller arm 11 and the right roller arm 12 are in the open state. The fiber optic tray 8 is placed in the corresponding fiber optic tray holding position 31 on the fiber optic tray conveying mechanism 3. The fiber optic tray conveying mechanism 3 moves the fiber optic tray 8 to the right to the clamping position.

[0077] 2. The front clamping plate 211 and the rear clamping plate 221 of the clamping mechanism 2 approach each other and clamp the optical fiber disk 8. The clamping mechanism 2 moves the optical fiber disk 8 upward to the winding position.

[0078] 3. The wheel arm opening and closing assembly 13 keeps both the left roller arm 11 and the right roller arm 12 in a closed state, forming a ring. The left roller arm 11 and the right roller arm 12 surround the fiber optic disk 8, and both the left roller 113 and the right roller 123 are connected to the fiber optic disk 8. Figure 16 As shown; the wrapping film tray 7 is mounted on the wrapping film tray mounting shaft 41, the wrapping film 71 passes downward through the wrapping film tray 7, the upper support shaft 14 is connected to the clamping roller 126, the clamping roller 126 is connected to the right roller 123 of the uppermost right roller assembly 121 in the right roller arm 12, the head of the wrapping film 71 is adhered to the outside of the right roller 123 of the uppermost right roller assembly 121, and the fiber optic tray 8 clamps the head of the wrapping film 71 with the right roller 123 of the uppermost right roller assembly 121;

[0079] 4. The three sets of air knives (15) begin to purge the fiber optic tray (8);

[0080] 5. The clamping mechanism 2 causes the fiber optic disk 8 to rotate. The rotation of the fiber optic disk 8 drives the left roller 113 and the right roller 123 to rotate. The left roller 113 and the right roller 123 wind the wrapping film 71 around the fiber optic disk 8. The number of turns can be determined as needed.

[0081] 6. After winding to the set number of turns, the right opening and closing cylinder 132 causes the right roller arm 12 to be in the open state. The height of the right roller arm 12 is higher than the height of the heating wire 51. The right roller arm 12 will not block the left and right movement of the heating wire 51. The heating wire 51 of the film cutting mechanism 5 moves to the left. The right roller arm 12 is in the open state and will not block the heating wire 51 from moving to the left to cut the wrapping film 71. After the heating wire 51 cuts the wrapping film 71, it moves to the right to reset.

[0082] 7. The clamping mechanism 2 rotates the fiber optic disk 8 one more turn, and wraps the tail of the winding film 71 on the fiber optic disk 8 around the fiber optic disk 8.

[0083] 8. The left opening and closing cylinder 131 puts the left roller arm 11 in the open state, and the clamping mechanism 2 moves the optical fiber disk 8 downward to the optical fiber disk conveying mechanism 3. The optical fiber disk conveying mechanism 3 sends the optical fiber disk 8 to the next process.
