Description

Technical Field

[0002] Optical fiber is a fiber made of glass or plastic. It is also a light transmission tool that uses the principle of total internal reflection to transmit light in these fibers. The transmitting device at one end of the optical fiber uses a light-emitting diode or a laser to send light pulses into the optical fiber. The receiving device at the other end of the optical fiber uses a photosensitive component to detect the pulses. The cable containing the optical fiber is called an optical cable. The optical fiber jumper is used as a jumper from the device to the optical fiber wiring link. It has a thicker protective layer and is generally used for the connection between the optical terminal and the terminal box.

Multiple groups of guide wheels 213 are arranged on the front and rear side walls of the mounting frame 211. The multiple groups of guide wheels 213 are arranged in two sections, respectively located between the left side wall of the connecting plate 215 and the leftmost end of the mounting frame 211 and between the right side wall of the connecting plate 215 and the left side wall of the connecting frame 226. The mounting frame 211 is also provided with an adjusting mechanism and a cleaning mechanism, and the cleaning mechanism includes a cleaning The cleaning frame 228 is fixedly connected between the front and rear side walls of the mounting frame 211, and a first motor 229 is installed on the top of the cleaning frame 228 through an extension frame. The front and rear sides of the top of the cleaning frame 228 are rotatably connected with transmission rods 230. The outer surface of the output end of the first motor 229 and the upper ends of the two groups of transmission rods 230 are fixedly connected with third transmission wheels 231, and the third transmission belts 232 are transmission-connected between the multiple groups of third transmission wheels 231. The front and rear inner walls of the cleaning frame 228 are rotatably connected with connecting rods 233. The outer surfaces of the two groups of connecting rods 233 are provided with a small section of thread, and the lower ends of the two groups of transmission rods 230 are fixed. The two connecting rods 233 are connected to a driving gear 234, and the outer surfaces of the two connecting rods 233 are fixedly connected with driven gears 235 meshing with the two driving gears 234, and the two driving gears 234 and the two driven gears 235 are bevel gears meshing with each other. The outer surfaces of the two connecting rods 233 are threadedly connected with moving plates 236. When the two moving plates 236 move toward the middle on the two connecting rods 233, they will slowly approach the outer surface of the plug core until the two clamping plates 237 clamp the plug core and stop moving. The tops of the two moving plates 236 are inserted with plug rods 239, and the interiors of the two moving plates 236 are provided with plug rods 239. The matching slots 240, the upper ends of the two groups of insertion rods 239 are fixedly connected with the clamping plates 237, the length of the two groups of slots 240 is equal to the length of the inner groove of the insert core, the upper inner wall of the cleaning frame 228 is slidably connected with two groups of first electric telescopic rods 238, the lower inner wall of the cleaning frame 228 is provided with a slide groove, and a slider is slidably connected in the slide groove. The two groups of first electric telescopic rods 238 are both installed on the two groups of sliders, and the extending ends of the two groups of first electric telescopic rods 238 are respectively fixedly connected to the tops of the two groups of clamping plates 237, the output end of the first motor 229 is fixedly connected with a cleaning brush 241, and the upper inner wall of the cleaning frame 228 is installed with an infrared distance sensor.

[0017] It should be noted that when the ferrule is transported on the conveyor belt 212 to the bottom of the cleaning rack 228, the first motor 229 is started, and the two sets of transmission rods 230 are driven to rotate through the multiple sets of third transmission wheels 231 and the third transmission belts 232, so that the two sets of transmission rods 230 drive the two sets of connecting rods 233 to rotate through the two sets of driving gears 234 and the driven gears 235. At this time, the two sets of moving plates 236 move toward the middle on the two sets of connecting rods 233, so that the two sets of clamping plates 237 move toward the middle to clamp the outer surface of the ferrule. At this time, the infrared distance sensor detects the distance between the top of the ferrule and the bottom of the cleaning brush 241. If the distance does not match the set distance, the clamping position is adjusted by adjusting the two sets of first electric telescopic rods 238 to achieve the set distance. When the distance matches, the two sets of first electric telescopic rods 238 respectively drive the two sets of clamping plates 237 to move upward, so that the plug core moves upward, so that the cleaning brush 241 enters the inner groove of the plug core for cleaning. At this time, the two sets of plug rods 239 slide upward in the two sets of slots 240. When the two sets of plug rods 239 slide to the highest point, the bottom of the cleaning brush 241 is in contact with the inner groove of the plug core, which achieves cleaning while avoiding damage to the inner groove of the plug core due to excessive adjustment, thereby affecting the subsequent dispensing work.

[0018] Furthermore, the cleaning mechanism also includes a connecting frame 226, which is fixedly connected between the front and rear sides of the top of the mounting frame 211, and a blower 227 is installed on the connecting frame 226. The left and right inner walls of the mounting frame 211 are rotatably connected with fixed rods 242, and the ends of the two groups of connecting rods 233 that are close to each other and the outer surfaces of the two groups of fixed rods 242 are fixedly connected with fourth transmission wheels 243, and the two groups of fourth transmission wheels 243 are transmission-connected with fourth transmission belts 244, and the outer surfaces of the two groups of fixed rods 242 are threadedly connected with clamping frames 245, and the tops of the two groups of clamping frames 245 are fixedly connected with limiting rods, and the other ends of the two groups of limiting rods are slidably connected to the upper inner wall of the connecting frame 226.

[0019] It should be noted that before the cleaning brush 241 cleans the ferrule, the first motor 229 is started, which will cause the two groups of connecting rods 233 to drive the two groups of fixed rods 242 to start rotating through the two groups of fourth transmission belts 244, so that the two groups of clamping frames 245 move to the middle on the two groups of fixed rods 242 respectively. At this time, the two groups of clamping frames 245 clamp the bottom of the ferrule to achieve early limit of the position of the ferrule, avoiding the need for most ferrules to be corrected by infrared distance sensors. When the two groups of clamping frames 245 clamp the bottom of the ferrule, start the blower 227 so that the air outlet of the blower 227 cleans the dust in the inner groove of the ferrule first, and then cooperates with the subsequent cleaning of the cleaning brush 241 to improve the cleaning effect.

[0020] Further, the adjustment mechanism includes two groups of fixed plates 214, both groups of fixed plates 214 are fixedly connected to the front side wall of the mounting frame 211, a connecting plate 215 is fixedly connected to the rear side of the top of the mounting frame 211, and two groups of rotating rods 216 are rotatably connected to the front side wall of the connecting plate 215, one group of transmission rods in the conveyor belt 212 extends outward and is fixedly connected to the first transmission wheel 217, and the other end of the left rotating rod 216 is also fixedly connected to the first transmission wheel 217, a first transmission belt 218 is transmission-connected between the two groups of first transmission wheels 217, the outer surfaces of the two groups of rotating rods 216 are fixedly connected to the second transmission wheels 219, and the two groups of second transmission wheels 219 are transmission-connected to each other. A second transmission belt 220 and the outer surfaces of the two groups of rotating rods 216 are connected to a conveyor belt 221 through two groups of transmission rollers. The outer surface of the conveyor belt 221 is provided with multiple groups of clamping arms 222, and the multiple groups of clamping arms 222 are all pneumatic clamping arms in the prior art. A baffle 223 is fixedly connected between the front and rear inner walls of the mounting frame 211, and the bottom of the baffle 223 abuts against the top of the mounting frame 211. An electric push rod 224 is installed on the front side wall of the mounting frame 211, and the extending end of the electric push rod 224 is fixedly connected with a cleaning plate 225, and the right side wall of the cleaning plate 225 abuts against the left side wall of the baffle 223. A sewage discharge trough matching the cleaning plate 225 is opened on the rear side wall of the mounting frame 211.

[0021] It should be noted that when the core is being driven by the conveyor belt 212, one of the transmission rods will drive a set of rotating rods 216 to rotate through two sets of first transmission wheels 217 and the first transmission belt 218. At this time, the two sets of rotating rods 216 start to drive through the second transmission belt 220, so that the conveyor belt 221 starts to rotate. During the rotation of the conveyor belt 221, the core can be clamped by multiple sets of clamping arms 222. After clamping, it starts to drive to the right. At this time, the conveyor belt 212 is still conveying to the right, and the clamped core is on the conveyor belt 2 21 is transmitted to the right from the top, and when the conveyor belt 212 passes through the baffle 223, the baffle 223 will block the fine impurities on its surface, and then the electric push rod 224 is started to make the cleaning plate 225 move successively to clean out the fine impurities blocked by the baffle 223 from the sewage tank, and then when the clamping arm 222 drives the plug to move to the rightmost side and move downward, the plug will be put down, so that the plug continues to move to the right on the conveyor belt 212 after cleaning, which further ensures the stability of the position of the plug during the transmission process and facilitates the subsequent cleaning work.

[0022] Furthermore, a connection box 246 is fixedly connected to the front and rear side walls of the mounting frame 211, a second electric telescopic rod 247 is installed on the front side wall of the front connection box 246, and an extending end of the second electric telescopic rod 247 is fixedly connected to a guide block 248, and a groove matching the insert is opened on the guide block 248.

[0023] It should be noted that after cleaning, the ferrule continues to move to the right and then engages in the slot on the guide block 248. At this time, the guide block 248 starts to drive the cleaned ferrule to move backward and engages in the rear connection box 246. Then the clamping mechanism 4 will clamp and move the slotted ferrule, and then place it in the discharge tray 3. Then the guide block 248 resets and continues to drive the next ferrule to move.

[0024] Furthermore, the top of the workbench 1 is connected to a discharge tray 3 through a driving motor, and the discharge tray 3 is placed on the workbench 1, which is connected to a clamping mechanism 4, a dispensing mechanism 5 and a unloading mechanism 6 through a transmission mechanism. The clamping mechanism 4 and the dispensing mechanism 5 are both clamping robots and dispensing machines in the prior art, and the unloading mechanism 6 is composed of a hydraulic cylinder and a pneumatic suction cup.

[0025] It should be noted that after the guide block 248 drives the core to move, the clamping mechanism 4 clamps it and places multiple cores on the discharge tray 3. The discharge tray 3 then rotates and the placed cores are glued by the glue dispensing mechanism 5. After the glue is dispensed, the discharge tray 3 rotates again and the hydraulic cylinder is started to move the suction cup downward, so that the suction cup removes one group of the discharge trays 3 after the glue is dispensed, and then it is transported by the conveying mechanism to complete the processing.

[0026] Further, the transmission mechanism includes an adjustment frame 111, the adjustment frame 111 passes through the front and rear side walls of the workbench 1, a second motor 112 is installed on the top of the adjustment frame 111, the output end of the second motor 112 is fixedly connected to a bidirectional lead screw 113, and the other end of the bidirectional lead screw 113 is rotatably connected to the adjustment frame 111, the outer surface of the bidirectional lead screw 113 is threadedly connected to two groups of first moving frames 114, and the outer surface of the limit bidirectional lead screw 113 is fixedly connected to a first gear 115, the left side of the workbench 1 A fixing frame 116 is fixedly connected to the side wall, a screw rod 117 is rotatably connected to the right side wall of the fixing frame 116, and the other end of the screw rod 117 is fixedly connected to a second gear 118 meshing with the first gear 115, the first gear 115 and the second gear 118 both adopt mutually meshing bevel gears, the outer surface of the screw rod 117 is threadedly connected to the second movable frame 119, and an adjustment plate 120 is fixedly connected to the rear side wall of the front first movable frame 114 and the right side wall of the second movable frame 119.

[0027] It should be noted that, when the second motor 112 is started, the two groups of first moving frames 114 begin to move toward the middle. At this time, the bidirectional lead screw 113 drives the lead screw 117 to rotate through the first gear 115 and the second gear 118, so that the two groups of first moving frames 114 move toward the middle while the second moving frame 119 also moves toward the middle, so that the two groups of adjustment plates 120 are respectively abutted against the discharge tray 3 at the bottom of the clamping mechanism 4 and the glue dispensing mechanism 5, thereby improving the stability during the placement of the insert and glue dispensing. At this time, the clamping mechanism 4, the glue dispensing mechanism 5 and the unloading mechanism 6 also move to the top of the discharge tray 3 to perform glue dispensing on the insert, thereby improving the stability during glue dispensing.

[0028] When the present invention is used: Step 1: First, when the core is being driven by the conveyor belt 212, one of the transmission rods will drive a set of rotating rods 216 to rotate through two sets of first transmission wheels 217 and the first transmission belt 218. At this time, the two sets of rotating rods 216 start to drive through the second transmission belt 220, so that the conveyor belt 221 starts to rotate. During the rotation process, the conveyor belt 221 can clamp the core through multiple sets of clamping arms 222. After clamping, it starts to drive to the right. At this time, the conveyor belt 212 is still moving to the right. Right transmission: the clamped ferrule is transmitted to the right on the top of the conveyor belt 221. When the conveyor belt 212 passes through the baffle 223, the baffle 223 blocks the fine impurities on its surface. Then, the electric push rod 224 is started to move the cleaning plate 225 successively to clean out the fine impurities blocked by the baffle 223 from the sewage tank. Then, when the clamping arm 222 drives the ferrule to move to the rightmost side and move downward, the ferrule is put down, so that the ferrule continues to move to the right on the conveyor belt 212 after cleaning. Step 2: When the ferrule is transported to the bottom of the cleaning rack 228 on the conveyor belt 212, the first motor 229 is started, and the two groups of transmission rods 230 are driven to rotate through the multiple groups of third transmission wheels 231 and the third transmission belts 232, so that the two groups of transmission rods 230 drive the two groups of connecting rods 233 to rotate through the two groups of driving gears 234 and the driven gears 235. At this time, the two groups of moving plates 236 move toward the middle on the two groups of connecting rods 233 respectively, so that the two groups of clamping plates 237 move toward the middle to clamp the outer surface of the ferrule. At this time, the infrared distance sensor will detect the distance between the top of the ferrule and the bottom of the cleaning brush 241. If it does not match the set distance, the clamping position is adjusted by adjusting the two groups of first electric telescopic rods 238 to reach the set distance. When the distance matches, the two groups of first electric telescopic rods 238 respectively drive the two groups of clamping plates 237 to move upward, so that the ferrule moves upward, so that the cleaning brush 241 moves in The two sets of rods 239 slide upward in the two sets of slots 240. When the two sets of rods 239 slide to the highest point, the bottom of the cleaning brush 241 abuts against the inner groove of the plug, thereby achieving cleaning while avoiding damage to the inner groove of the plug due to excessive adjustment. Before the cleaning brush 241 cleans the plug, the first motor 229 is started, which will cause the two sets of connecting rods 233 to drive the two sets of fixing rods 242 to start rotating through the two sets of fourth transmission belts 244, so that The two groups of clamping frames 245 are respectively moved toward the middle on the two groups of fixing rods 242. At this time, the two groups of clamping frames 245 clamp the lower part of the ferrule to achieve early limit of the position of the ferrule, avoiding the need for most ferrules to be corrected by the infrared distance sensor. When the two groups of clamping frames 245 clamp the lower part of the ferrule, the blower 227 is started, so that the air outlet of the blower 227 cleans the dust in the inner groove of the ferrule first, and then cooperates with the subsequent cleaning brush 241 for cleaning; Step three: Start the second motor 112, so that the two groups of first moving frames 114 start to move toward the middle. At this time, the bidirectional lead screw 113 drives the lead screw 117 to rotate through the first gear 115 and the second gear 118, so that the two groups of first moving frames 114 move toward the middle while the second moving frame 119 also moves toward the middle, so that the two groups of adjusting plates 120 are respectively against the discharge tray 3 at the bottom of the clamping mechanism 4 and the dispensing mechanism 5, which improves the stability when placing the plug and dispensing. At this time, the clamping mechanism 4, the dispensing mechanism 5 and the unloading mechanism 6 also move to the top of the discharge tray 3, and the clamping mechanism 4 clamps them, and multiple plugs are placed on the discharge tray 3, and then the discharge tray 3 rotates, and the placed plugs are dispensed through the dispensing mechanism 5. After the dispensing is completed, the discharge tray 3 rotates again, and the suction cup is moved downward by starting the hydraulic cylinder, so that the suction cup removes one of the groups of discharge trays 3 after the dispensing is completed, and then it is transported by the conveying mechanism to complete the processing.
