Description

Automatic polishing wire assembly for polishing fiber optic MPO patch cords Technical Field

[0001] This invention belongs to the field of optical fiber patch cord polishing technology, specifically relating to an automatic polishing wire assembly for polishing optical fiber MPO patch cords. Background Technology

[0002] The polishing process for fiber optic MPO patch cords generally involves several steps: adhesive removal, rough polishing, fine polishing, fiber drawing, and polishing. Each step requires a separate polishing fixture and a dedicated fiber optic polishing machine. However, because the pigtail cables of fiber optic MPO patch cords are quite long, the entire reel can typically weigh 50-100 kg. Therefore, when using separate fiber optic polishing machines for polishing, the polishing fixture must be disassembled after each polishing step to clean the end face of the fiber optic MPO patch cord before it can be reassembled onto the next polishing machine for further polishing. Due to the weight of the pigtail cables, the fiber optic MPO patch cords are difficult to handle during polishing, resulting in low polishing efficiency. Summary of the Invention

[0003] To address the aforementioned technical problems, the present invention aims to provide an automatic polishing line assembly for polishing fiber optic MPO patch cords. This assembly consists of a polishing machine and a cleaning machine arranged side by side, with the polishing and cleaning processes performed sequentially. This eliminates the need for manual replacement of the polishing fixtures, effectively improving polishing efficiency.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] An automated polishing line assembly for polishing fiber optic MPO patch cords includes several polishing units arranged side by side. Each polishing unit is equipped with a polishing machine for placing polishing fixtures and a cleaning machine for cleaning the polishing fixtures.

The pressurization push rod is disposed at the telescopic end of the pressurization cylinder. The proportional valve is disposed on the pressurization cylinder. The proportional valve controls the pressurization cylinder to drive the pressurization push rod downward to pressurize the grinding clamp located on the grinding machine.

[0014] Furthermore, the lower end of the lifting slide plate is also provided with a longitudinal telescopic component, and the clamping cylinder is disposed on the longitudinal telescopic component; the sliding plate is disposed on one side of the pressurizing cylinder and opposite to the clamping cylinder.

[0015] Because the present invention adopts the above technical solution, it has the following advantages and effects:

Detailed Implementation

[0031] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings to provide a clearer understanding of the purpose, features, and advantages of the present invention. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of the present invention, but are merely illustrative of the essential spirit of the technical solution of the present invention.

[0032] As shown in Figures 1-8 and 11-12, this invention provides an automatic polishing assembly for polishing fiber optic MPO patch cords. It includes several polishing machine units 1 arranged side-by-side. The table of each polishing machine unit 1 is equipped with a polishing machine 102 for placing a polishing fixture 103 and a cleaning machine 101 for cleaning the polishing fixture 103. A polishing support 107 is also provided on the table of the polishing machine unit 1. A linear sliding assembly 105 is mounted on the polishing support 107, located above the polishing machine 102 and the cleaning machine 101. A pair of clamping assemblies 106 for holding the polishing fixture 103 are slidably connected to the linear sliding assembly 105. The linear sliding assembly 105 drives the pair of clamping assemblies 106 to synchronously reciprocate linearly, clamping and moving the polishing fixture 103 synchronously.

[0033] Specifically, in this invention, an automatic grinding line is formed by setting up five grinding machine groups 1 side by side, which sequentially perform adhesive removal grinding, coarse grinding, fine grinding, fiber drawing grinding, and polishing grinding. Of course, different numbers of grinding machine groups 1 can be set up to form an automatic grinding line according to different grinding processes.

[0034] The grinding unit 1 includes a grinding cabinet 104. The bottom of the grinding cabinet 104 is equipped with casters 1041 and support bases 1042 for easy movement and support. The grinding machine 102 and the cleaning machine 101 are arranged horizontally and spaced apart in the middle of the table of the grinding cabinet 104. A grinding bracket 107 is provided at the rear end of the table of the grinding cabinet 104. The grinding bracket 107 is a gate-shaped bracket. The two side columns of the gate-shaped bracket are fixed on the table. The upper end of the grinding bracket 107 extends towards the front of the grinding cabinet 104. A linear sliding component 105 is provided at the end of its extension. The linear sliding component 105 is located above the grinding machine 102 and the cleaning machine 101.

[0035] Each grinding machine group 1 has a grinding machine 102 for grinding fiber optic MPO patch cord connectors mounted on a grinding fixture 103, and a cleaning machine 101 for cleaning the fiber optic MPO patch cord connectors on the corresponding grinding fixture 103 after grinding. The grinding machine 101 is preferably an automatic grinding machine for fiber optic connectors disclosed in publication number CN221583210U, and the cleaning machine 101 is preferably an ultrasonic cleaner.

[0036] When the grinding unit 1 is working, the linear sliding component 105 on each grinding unit 1 synchronously drives a pair of grinding jigs 103 connected to it to move to the outer end of the grinding machine 102 of the grinding unit 1 to grab the ungrinded grinding jigs 103 or the grinding jigs 103 that have been ground on the adjacent side. Then it moves to the other side to place the grabbed grinding jigs 103 on the corresponding cleaning machine 101 or grinding machine 102 station for synchronous cleaning or grinding. This process is repeated to realize the parallel transfer of the grinding jigs 103 on the adjacent grinding units 1 until the cleaning is completed from the last grinding unit 1, thus completing the entire grinding process.

[0037] A protective cover 4 is provided on the front side of the extended end of the grinding bracket 107 of the grinding unit 1. The protective cover 4 protects the cleaning machine 101 and the grinding machine 102 on the grinding unit 1 to prevent the grinding liquid or cleaning liquid from splashing when grinding or cleaning the grinding fixture 103.

[0038] Meanwhile, each grinding unit 1 has a protective door on the rear side of the grinding bracket 107, which facilitates the installation and debugging of the grinding machine 102 or the cleaning machine 101.

[0039] Furthermore, a conveyor belt 3 is also provided on the table of the grinding unit 1, and the conveyor belt 3 extends out of both ends of the grinding unit 1.

[0040] Specifically, a conveyor belt 3 is installed on the front side of the upper end of the table of the grinding cabinet 104. The conveyor belt 3 is used to transport the pigtail cable of the fiber optic MPO patch cord. When the fiber optic connector on the fiber optic MPO patch cord is fixed on the grinding fixture 103 and transferred sequentially by the linear sliding component 105, the pigtail cable of the fiber optic MPO patch cord is placed on the conveyor belt 3 for synchronous transmission.

[0041] Of course, in order to facilitate the transmission of pigtail cables, a cable box 401 is placed on the conveyor belt 3, and the corresponding pigtail cable on each grinding fixture 103 can be placed in the corresponding cable box 401 for synchronous transmission.

[0042] Furthermore, a vertical pressure assembly 109 is provided on the clamping assembly 106 located at least on the side above the grinder 102.

[0043] Specifically, in this invention, a vertical pressure component 109 is provided on the corresponding clamping assembly 106 on the side where pressure needs to be applied to the grinding machine 102. When the grinding clamp 103 is transferred to the corresponding grinding machine, pressure is applied to the grinding clamp 103 through the vertical pressure component 109.

[0044] Furthermore, to facilitate the pressurization of the vertical pressurizing component 109, a support component 108 is also provided on the table of the grinding unit 1, with one end of the vertical pressurizing component 109 slidably connected to the support component 108. The support component 108 is fixed on both sides of the corresponding grinding machine 101, and when the vertical pressurizing component 109 applies downward pressure, it can rely on the support component 108 to provide certain support.

[0045] Furthermore, since the grinding fixture 103 needs to enter and exit from both sides of the grinding unit 1, fixture placement plates 2 extending outward from the grinding unit 1 are respectively provided on the grinding unit 1 at both ends.

[0046] Specifically, the initial grinding fixture 103 before degumming and the finished grinding fixture 103 can be placed on the fixture placement plate 2, so that the fixture holding assembly 106 on the first grinding unit 1 can hold the initial grinding fixture 103 from the outside. The fixture holding assembly 106 on the last grinding unit 1 can place the finished grinding fixture 103 on the fixture placement plate 2 for easy manual removal, while also making room for the grinding fixture of the previous process.

[0047] Furthermore, the support assembly 108 includes a pair of spaced-apart support columns 1082, a linear guide plate 1081, and a sliding plate 1083. The linear guide plate 1081 is disposed at the upper end of the support column 1082, and the sliding plate 1083 is disposed on one side of the vertical pressurization assembly 109. The other side of the sliding plate 1083 is slidably connected to the linear guide plate 1081.

[0048] Specifically, the support columns 1082 are respectively set on both sides of the grinding machine 1 and are integrated with the grinding fixture fixing frame. One side of the sliding plate 1083 is nested on the linear guide plate 1081 and can slide off the linear guide plate 1081. When the fixture holding assembly 106 moves to the adjacent station to grab the grinding fixture 103, the sliding plate 1083 disengages from the linear guide plate 1081. When the fixture holding assembly 106 completes the clamping of the grinding fixture 103 and resets, the fixture holding assembly 106 can drive the sliding plate 1083 to embed into one side of the linear guide plate 1081, so that the grinding fixture 103 can be provided with stable support force by the bracket assembly 108 when pressure needs to be applied.

[0049] As shown in Figures 9 and 10. Further, the linear sliding assembly 105 includes a linear displacement slide 1051, a linear slide plate 1052, and a connecting plate 1053. The linear slide plate 1052 is slidably connected to the linear displacement slide 1051. The connecting plate 1053 is disposed on the linear slide plate 1052. The connecting plate 1053 is parallel and spaced apart from the linear displacement slide 1051. A pair of clamping assemblies 106 are disposed at intervals on the connecting plate 1053.

[0050] Specifically, the bottom of the linear displacement slide 1051 is fixed to the upper front extension of the grinding bracket 107 via an extension plate 1054, and the linear slide plate 1052 is nested on the slider at the top of the linear displacement slide 1051. The middle part of the connecting plate 1053 is fixed to the linear slide plate 1052, and clamping assemblies 106 are provided at both ends of the connecting plate 1053 extending from the linear slide plate 1052. The clamping assemblies 106 are perpendicular to the connecting plate 1053, and the spacing between a pair of clamping assemblies 106 is the same as the spacing between the grinding machine 102 and the cleaning machine 101, so that adjacent clamping assemblies 106 on the entire grinding unit 1 can be moved the same distance each time and placed on the corresponding grinding machine 102 and cleaning machine 101. The linear displacement slide 1051 is preferably an electric slide, which drives the slider to move linearly by rotating the lead screw driven by a motor.

[0051] As shown again in Figures 11 and 12, the clamping assembly 106 further includes a vertical lifting slide 1061, a lifting slide plate 1062, a clamping cylinder 1063, and a clamping plate 1064. The bottom of the vertical lifting slide 1061 is connected to the connecting plate 1053, and the lifting slide plate 1062 is slidably connected to the vertical lifting slide 1061. The clamping cylinder 1063 is provided at the lower end of the lifting slide plate 1062, and the clamping plates 1064 for clamping the grinding fixture 103 are connected to both clamping ends of the clamping cylinder 1063.

[0052] Specifically, the bottom of the vertical lifting slide 1061 is connected to the connecting plate 1053 via the support plate 109. The vertical lifting slide 1061 is perpendicular to the connecting plate 1053. The lifting slide plate 1062 is connected to the slider of the vertical lifting slide 1061. When the slider of the vertical lifting slide 1061 moves to its upper end, the lower end of the lifting slide plate 1062 extends out of the lower end of the vertical lifting slide 1061 to facilitate downward movement to clamp the grinding fixture 103.

[0053] The vertical lifting slide 1061 is preferably an electric slide. The clamping cylinder 1063 is a finger cylinder with two opposing clamping ends, and the preferred model of the clamping cylinder 1063 is the Airtac finger cylinder HFP32. A pair of clamping plates 1064 are vertically connected to the two clamping ends of the finger cylinder, and the pair of clamping plates 1064 are spaced apart to facilitate clamping the pressure column on the grinding fixture 103.

[0054] Furthermore, to facilitate the adjustment of the position of the clamping cylinder 1063 to correspond with the grinding clamp 103, a longitudinal telescopic component 110 is also provided at the lower end of the lifting slide plate 1062, and the clamping cylinder 1063 is mounted on the longitudinal telescopic component 110. The longitudinal telescopic component 110 can adjust the longitudinal position of the clamping cylinder 1063 above the grinding machine.

[0055] One telescopic end of the longitudinal telescopic component 110 is connected to the L-shaped slide plate 1065, and one fixed end of the longitudinal telescopic component 110 is connected to the lifting slide plate 1062. A clamping cylinder 1063 is located at the lower end of the L-shaped slide plate 1065. The longitudinal telescopic component 110 can be a telescopic cylinder or an electric slide table. The clamping cylinder 1063 is connected to the telescopic end of the telescopic cylinder or the slider of the electric slide table. The preferred telescopic cylinder model is HLS 20x50.

[0056] As shown in Figure 13, the vertical pressurization assembly 109 further includes a pressurization cylinder 1091, a proportional valve, and a pressurization push rod 1092. The pressurization cylinder 1091 is located at the end of the clamping cylinder 1063 and between a pair of clamping plates 1064. The pressurization push rod 1092 is located at the telescopic end of the pressurization cylinder 1091. The proportional valve is provided on the pressurization cylinder 1091. The proportional valve controls the pressurization cylinder 1091 to drive the pressurization push rod 1092 downward to pressurize the grinding clamp 103 located on the grinding machine 102.

[0057] Specifically, one side of the pressurizing cylinder 1091 is fixed to the end of the clamping cylinder 1063 between a pair of clamping plates 1064. When pressurization of the grinding fixture 103 is required, the grinding fixture 103 is first moved onto the grinding machine 102 by clamping the pressurizing column on the grinding fixture 103 by the pair of clamping plates 1064 on the clamping cylinder 1063. Then, the pressurizing cylinder 1091 drives the pressurizing rod 1092 downward to pressurize the pressurizing column. The upper and lower ends of the pressurizing cylinder 1091 are respectively provided with an air inlet and an air outlet. A proportional valve is installed at the air source port of the pressurizing cylinder 1091 through the air inlet and air outlet, ensuring a tight and reliable connection between the proportional valve and the air source and the pressurizing cylinder 1091. The control signal line of the proportional valve is connected to the controller, and the controller controls the proportional valve to achieve pressure regulation of the pressurizing cylinder 1091. The preferred model of the pressurizing cylinder 1091 is SDADS 20X50.

[0058] Furthermore, the sliding plate 1083 is disposed on one side of the pressurizing cylinder 1091 and opposite to the clamping cylinder 1063. One side of the sliding plate 1083 is fixed on the pressurizing cylinder 1091, and the other side of the sliding plate 1083 is provided with a U-shaped groove. The U-shaped groove is nested in one side of the linear guide plate 1081 and slides along the linear guide plate 1081. When the pressurizing cylinder 1091 drives the pressurizing rod 1092 to press down, the sliding plate 1083 is supported by the linear guide plate 1081 to provide support force.

[0059] In use, the present invention assembles the grinding machine unit 1 according to different grinding processes. The first grinding fixture 103 is placed on the fixture placement plate outside the first-process grinding machine unit 1. Then, all grinding machines are started simultaneously, and the fixture holding components 106 on the grinding machine unit 1 move synchronously. The fixture holding components on the first-process grinding machine unit clamp the grinding fixture 103 and move it to the fiber optic grinding machine of the first-process grinding machine unit for grinding. Then, the second grinding fixture is placed on the fixture placement plate. After the grinding fixture on the first-process grinding machine unit 1 has completed grinding, the fixture holding components move synchronously to clamp the second grinding fixture. The first grinding fixture is clamped and moved to the cleaning machine 101 of the first-stage grinding unit for cleaning. After the first-stage grinding unit completes grinding and cleaning, the third grinding fixture is placed, and the clamping assembly of the second-stage grinding unit 1 moves synchronously to continue clamping the third grinding fixture. The clamping assembly of the second-stage grinding unit 1 then moves to grab the grinding fixture cleaned in the first stage. This cycle repeats, sequentially grinding and cleaning the grinding fixtures on adjacent grinding units, until the final cleaning stage is completed. After cleaning, the grinding fixtures are moved to the fixture placement plate outside the final-stage grinding unit. Throughout the grinding and cleaning process, the pigtail cables on the grinding fixtures are placed in a cable box on the conveyor belt for transport.

[0060] This invention uses a PLC controller to program and control the sequence of actions. The PLC controller is existing technology and will not be described in detail here.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
