Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber lasers, and in particular to an automatic inner-sealing substrate device for an optical fiber combiner. Background Art

[0002] The beam combiner is an optical component used to combine multiple optical signals into one output. The quartz substrate is long and has a concave cross section. The groove of the substrate is used to fix the optical fiber bundle and has functions such as heat transfer. It is an important part of the beam combiner and is bonded to the lower shell with glue.

[0003] At present, the lower shell groove is automatically dispensed with glue using a glue dispenser. After dispensing, the quartz substrates are manually placed into the groove one by one, and then an aluminum alloy strip tool is used to apply downward pressure on each bonded quartz substrate. The purpose is to allow the glue to be spread under pressure and fill the space between the substrate and the lower shell, and the substrate and the bottom of the lower shell groove are bonded. The timeliness of the glue requires that the quartz substrate be quickly placed into the groove after dispensing, and the substrate must be kept under pressure. The longer the waiting time, the more likely the glue will self-cure;

[0004] In manual production, to improve efficiency, the glue dispenser will dispense 20 at a time. The quartz substrate can only be placed manually after the glue is dispensed manually. The quartz substrate cannot be placed during the operation of the equipment. The glue dispensing time is connected in series with the placement time and the pressing time. In addition, the manual pressing is done by hand, and the force is uneven, resulting in height differences at both ends of the substrate, left and right height differences, and even the end of the substrate is pressed to one end and ejected, protruding from the notch of the lower shell, causing defects.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1 , 5and 12. In the present embodiment, an automatic inner-sealing substrate device for an optical fiber combiner comprises an equipment table 1, on which a shift fork conveying assembly B is installed, on which a glue dispensing assembly, a pressure maintaining device B6 and a material receiving table B2 are installed, and on the equipment table 1 are also installed three groups of feeding ends which are all connected to the shift fork conveying assembly B, on the leftmost and rightmost feeding ends are respectively installed a lower shell loading assembly A and a finished product unloading assembly C, the leftmost feeding end is connected to the material receiving table B2, on the rightmost feeding end is also installed a heating table C10, on the top of the heating table C10 is installed a heating plate C11, on the table top of the equipment table 1 is installed a substrate loading correction assembly D which cooperates with the middle feeding end, the substrate loading correction assembly D comprises a loading portion which is installed on the equipment table 1 and is located above one of the feeding ends, and the equipment table 1 is also installed a correction portion between the feeding end and the upper table B1.

[0036] In the above structure, the feeding processes of the three feeding ends are distributed from left to right and from long to short. The leftmost feeding end moves the lower shell to the appropriate position and docks with the receiving table, and cooperates with the lower shell loading assembly to move the lower shell to the receiving table, and then pushes it one by one through the lower shell to guide it to the fork conveying assembly, and the lower shell is pushed to the right by the fork conveying assembly until it is moved to the bottom of the glue dispensing assembly to complete the gluing operation. The middle feeding end moves the quartz substrate to the appropriate position, and cooperates with the substrate loading correction assembly to first complete the correction operation on the quartz substrate, and then transports it to be pressed and fitted with the lower shell, and then transfers it to the bottom of the pressure holding assembly through the fork conveying assembly to complete the pressing operation. After pressing, it is moved to the tail end, opposite to the heating plate, and the finished product unloading operation is completed through the finished product unloading assembly. The single-device integrated assembly line production method is used to ensure that the bonding is completed in a very short time after the glue is dispensed, thereby avoiding the influence of glue self-curing on the product.

[0037] like Figure 2 , 6and 12, the feeding end includes three material platforms A1 fixed on the equipment table 1, a linear cylinder A2 is installed inside the material platform A1, a carrier plate A3 sliding with the material platform A1 is fixed on the moving end of the linear cylinder A2, five stoppers A4 surrounding the tray A7 are fixed on the plate surface of the carrier plate A3, and two convex pillars A6 extending to the bottom of the tray A7 are fixed, and four pads A5 are fixed on the moving plate A3, and concave surfaces are formed on both sides of the carrier plate A3. The five stoppers are distributed on the outside of the tray to limit the tray, and when the tray is placed on the carrier plate, the convex pillars will also be inserted into the bottom of the tray to improve the stability of the tray, and at the same time, the accuracy of the tray placement position can be improved. Because there is a concave surface on the carrier plate, the two sides of the tray are partially exposed, which is convenient for manual lifting of the tray. At the same time, the pads will also raise the tray to a certain height, so as to facilitate the removal of the tray and reduce the contact area with the carrier plate. The linear cylinder can drive the carrier plate to move, so that the carrier plate drives the tray to dock with the receiving table, the substrate loading correction component and the heating plate respectively, and complete the feeding operation.

[0038] Among them, Figure 2 In the direction shown, the lower shell loading assembly A includes a stand A8 fixed on the leftmost material platform A1, the stand A8 is concave in shape, a belt conveyor A9 and a sliding support plate A10 are installed on the top of the stand A8, the belt end of the belt conveyor A9 is fixed to the support plate A10, a top cylinder A11 is installed on the support plate A10, the piston rod of the top cylinder A11 is fixed to the top plate A12, a side block A13 is fixed on the left side of the top plate A12, and a paddle plate A14 is hinged at the bottom, and a bottom block A15 is fixed on the left side of the paddle plate A14 and is vertically symmetrical with the side block A13, a waist hole A18 is opened on the side block A13, the internal thread of the bottom block A15 is connected to a bolt A16 passing through the waist hole A18, and the outer side of the bolt A16 is located above the side block A13 and is sleeved with a spring A17. When the feeding end drives the tray carrying the lower shell to dock with the receiving table, the belt conveyor will drive the support plate to move, so that the paddle plate moves to the side of the tray opposite to the receiving table, and then the top plate is driven to move by the top cylinder, so that one side of the paddle plate is opposite to the lower shell. When the support plate is driven to move by the belt conveyor, the lower shell can be transferred to the receiving table by pushing to complete the loading operation. When the paddle plate contacts the lower shell when paddles, the bolt moves in the threaded hole and squeezes the spring four to adjust the angle of the paddle plate. The paddle plate can play a buffering role when paddles the lower shell, which can effectively avoid damage to the product caused by hard contact with the lower shell.

[0039] like Figure 3 and 4 ,by Figure 3In the direction shown, the fork conveying assembly B includes an upper platform B1 fixed on the equipment platform 1, a boss B3 is fixed on the upper platform B1, and material blocking plates are formed on the left and right sides of the boss B3. The material receiving platform B2, the dispensing assembly and the pressure holding device B6 are all installed on the upper platform B1 from left to right. The upper platform B1 is installed with a side push cylinder B14 on the back of the boss B3, and a side push plate B15 slidably connected to the piston rod of the side push cylinder B14. The side push plate B15 is installed with forward push cylinders B16 located on the left and right sides of the side push cylinder B14. The piston rods of the two forward push cylinders B16 are connected to the piston rods of the two front push cylinders B16. A connecting plate B17 is fixed in the middle, and four equidistantly arranged fixed plates B18 are fixed on the connecting plate B17, the bottom of the fixed plate B18 is slidingly connected to the plate surface of the side push plate B15, an auxiliary clamping plate B23 is fixed on the left side of the plate surface of the fixed plate B18, and a movable clamping plate B20 opposite to the auxiliary clamping plate B23 is hinged on the right side, and a pushing cylinder B19 opposite to the tail end of the movable clamping plate B20 is also fixed on the right side of the plate surface of the fixed plate B18, and bolts B21 are fixed on both the fixed plate B18 and the movable clamping plate B20, and a tension spring B22 is installed between the two bolts B21. First, the lower shell loading assembly pushes the lower shell onto the boss, and the forward push cylinder pushes the connecting plate. The connecting plate can drive the four fixed plates to move at the same time, so that the auxiliary clamping plate and the movable clamping plate are moved to the boss, and the lower shell is located between the auxiliary clamping plate and the movable clamping plate. The pushing cylinder piston rod is pushed out, and the movable clamping plate at the end opposite to the pushing cylinder moves outward. At the same time, the bolt 2 on the movable clamping plate will also move. During the movement, the tension spring will be stretched, and the other end of the movable clamping plate will move inward. Therefore, with the cooperation of the auxiliary clamping plate, the product can be clamped. At the same time, when the pushing cylinder is reset, the movable clamping plate can also be pulled back to its original position under the elastic force of the tension spring, so that the auxiliary clamping plate and the movable clamping plate are opened. During the clamping process, the side push cylinder drives the side push plate to move, so the fixed plate can be driven to move together through the side push plate, so that the lower shell can be clamped and moved through the auxiliary clamping plate and the movable clamping plate.

[0040] Among them, a plurality of side blocks B4 are fixed on the front of the boss B3, and a plurality of counter blocks B24 are fixed on the top and are distributed opposite to the side blocks B4. The top surface of the side block B4 is higher than the top surface of the counter block B24. Both the side blocks B4 and the counter blocks B24 are made of soft materials. The top surface of the counter block B24 is located below the auxiliary clamping plate B23 and the movable clamping plate B20. Three pushing and clamping cylinders B5 are installed on the table top of the upper platform B1. The ejection ends of the pushing and clamping cylinders B5 are respectively located between the plurality of counter blocks B24. Three pairs of blocks B13 are fixed on the top of the boss B3 and are respectively located between the plurality of counter blocks B24. The counter blocks B13 are made of hard material, and each pair of counter blocks B13 is respectively opposite to the corresponding pushing and clamping cylinders B5. The side blocks and counter blocks can be used to limit the two sides of the boss, thereby preventing the lower shell from falling or shifting during transportation. At the same time, because the side blocks and counter blocks are made of soft materials, they can prevent the side blocks and counter blocks from causing wear and damage to the lower shell during movement of the lower shell. The left push-and-clamp cylinder is opposite to the dispensing assembly, the middle push-and-clamp cylinder is located at the substrate loading correction assembly, and the right push-and-clamp cylinder is located below the pressure holding device. The three push-and-clamp cylinders and three pairs of blocks are respectively divided into a dispensing area, an assembly area and a pressure holding area. When the lower shell moves from left to right, the push-and-clamp cylinder drives the ejection end to be ejected, and at the same time, the corresponding counter blocks can be used to fix the lower shell. Because the counter blocks are made of hard materials, the lower shell can be clamped more firmly, and the displacement that affects the transportation accuracy can be avoided. At the same time, the distribution of the blocks can also reduce damage caused by contact with the product.

[0041] like Figure 5 The glue dispensing assembly includes a side frame B7 fixed on the upper platform B1, a belt transmission device B8 is installed on the side frame B7, a moving block sliding with the side frame B7 is fixed on the belt of the belt transmission device B8, an ejection cylinder B9 is installed on the moving block, a concave block B10 is fixed to the ejection end of the ejection cylinder B9, a glue head B12 is installed at the bottom of the concave block B10, and a rubber hose B11 connected to the glue head B12 is fixed on the inner side, a U-shaped notch is provided on the glue head B12, and an arc-shaped notch docking with one end of the U-shaped notch is also provided, and the head of the glue head B12 is locked by two screws. When the lower shell is positioned under the glue dispensing component, the ejection cylinder drives the recessed block to move downward until the tube of the rubber hose falls into the groove of the lower shell, and then the shifting block is moved by the belt transmission device, so that the rubber hose can be moved left and right to complete the gluing operation on the lower shell. At the same time, the rubber head is provided with a U-shaped notch and an arc notch, so that the rubber head is divided into two halves without separation, and the rubber needle of the rubber hose can be clamped and fixed evenly by tightening the screws.

[0042] like Figure 6-11The loading part includes a stand D1 fixed on the equipment table 1, the stand D1 is located on the back of the middle material table A1, a horizontal linear module D2 is installed on the front of the stand D1, a moving plate D3 is fixed on the moving end of the horizontal linear module D2, a longitudinal linear module D4 is installed on the surface of the moving plate D3, a vertical plate D5 is fixed on the moving end of the longitudinal linear module D4, a drooping plate D6 is slidably connected to the vertical plate D5, a counterweight block D7 is installed on the top of the drooping plate D6, and three adsorption blocks D8 are installed on the left side. Through the cooperation of the horizontal linear module and the longitudinal linear module, the movable plate can be driven to move left and right, and the vertical plate can be driven to move up and down respectively. At the same time, the drooping plate follows the movement, and cooperates with the adsorption block to adsorb and place the quartz substrate on the correction part, and move it from the correction part to the boss to be assembled and fitted with the lower shell. At the same time, when fitting and taking the plate, the longitudinal linear module drives the vertical plate to move up and down. When the vertical plate is lifted, the drooping plate will move down to the lowest position under the gravity of the counterweight block. At the same time, when the vertical plate moves down, the drooping plate, under the gravity of the counterweight block, makes the three adsorption blocks contact and adsorb the quartz substrate, and then move it to the boss to be assembled and fitted with the lower shell. During the downward pressing process, a slot-type photoelectric sensor is also installed on the vertical plate, and the drooping plate A sensing sheet is installed. When the sagging plate drives the adsorption block to assemble the quartz substrate and the lower shell body qualified, the quartz substrate will accurately fall into the lower shell body to complete the fitting. If the quartz substrate is not accurately positioned and offset during assembly, or there is a problem with the size of the quartz substrate itself, the quartz substrate will not accurately fall into the lower shell body. The quartz substrate will have direct contact with the upper surface of the lower shell body and above the notch. When the longitudinal linear module continues to move downward, the sagging plate will not continue to move downward, and will slide relative to the vertical plate. The sensing sheet will enter the slot-type photoelectric sensor and then issue an alarm. The quartz substrate that failed to fit can be reconfirmed or reused. If the sagging plate is fixed to the vertical plate, when there is an assembly mismatch, the large downward pressure of the sagging plate will cause damage to the quartz substrate or the lower shell body.

[0043] Among them, Figure 8In the direction shown, the correction part includes a side table D16 fixed on the equipment table 1, the side table D16 is located on the left side of the middle material table A1, and a driving motor D17 is installed on the right and left walls of the side table D16. The front of the side table D16 and the front of the right driving motor D17 are fixed with a side plate D18, and a slot-type photoelectric sensor D19 is installed on the side plate D18. The driving end of the driving motor D17 is fixed with a rotating piece D20 in a mountain shape that can extend to the inner side of the slot-type photoelectric sensor D19, one end of the rotating piece D20 is hinged with a short rod D22, and the top end is fixed with a spring D21 fixed to the side plate D18, and the other end of the short rod D22 is installed with a side clamp end and a counter clamp end. When the drive motor is not powered on, the elastic force of spring 1 will pull the rotating piece toward the side plate, so that the side clamp end and the opposite clamp end are both in a closed state. When the drive motor is running, the rotating piece is driven to rotate, and one end of the rotating piece rotates to the slot-type photoelectric sensor, and the position of the side clamp end and the opposite clamp end is corrected by the slot-type photoelectric sensor.

[0044] The side clamp end includes an upper block D28 fixed on the side table D16, two guide rods D35 are passed through the upper block D28, a spring three D36 is embedded and fixed on one side of the upper block D28 between the two guide rods D35, a locking block D34 is fixed on the outer side of the guide rod D35, a correction block D37 opposite to the upper block D28 is fixed between the tops of the two locking blocks D34, a convex block is formed on the side of the correction block D37 opposite to the upper block D28, the upper block D28 is L-shaped, and the bottom of the convex block of the correction block D37 is aligned with the convex end of the upper block D28. The top of the correction block D37 is attached to the bottom of the correction block D37, and the bolt three D38 connected to the spring three D36 is connected to the upper block D28. The upper block D28 is rotatably connected with the rotating shaft D32. The two ends of the rotating shaft D32 extend from the two sides of the upper block D28 respectively. Push blocks D33 are fixed to the outer sides of the two ends of the rotating shaft D32, and the left end is fixed with a side rod D31 hinged to the corresponding short rod D22. Extrusion blocks D40 attached to the corresponding pushing blocks D33 are fixed on both sides of the correction block D37, and limiting columns D41 opposite to the pushing blocks D33 are fixed on both sides of the upper block D28. When the push block rotates and retreats, the elastic force of the spring three drives the correction block to approach the upper block by pulling the bolt three to complete the push correction processing of the quartz substrate. At the same time, a protruding end is formed on the side opposite to the correction block, and the protruding end is also made of soft material to avoid damage to the quartz substrate during the push correction process.

[0045] In addition, Figure 8In the direction shown, the clamping end includes a slider D27 slidably connected to both sides of the side platform D16 and two springs D29 embedded and fixed inside the two sides, and the opposite ends of the two sliders D27 are fixed with clamping claws D30 fixed with the corresponding springs D29, and the front of the side platform D16 is rotatably connected to two eccentric rods D26 extending into the slide groove of the slider D27, and the eccentric end of the eccentric rod D26 is in contact with the corresponding slider D27, and the position where the eccentric rod D26 and the slider D27 are in contact is eccentric, and the outer end of the eccentric rod D26 is fixed with an L-shaped block D23 hinged to the corresponding short rod D22, one end of the L-shaped block D23 is hinged with a long rod D24, and the other end of the long rod D24 is hinged with a hinge block D25 fixed to another eccentric rod D26, and one side of the side platform D16 is fixed with a limit block D39 opposite to one end of the L-shaped block D23. The right driving motor drives the rotary piece to rotate, and the short rod drives the L-shaped block to rotate. While the L-shaped block rotates, the hinge block is driven to rotate together through the long rod. At the same time, the hinge block and the L-shaped block also drive the eccentric rod to rotate at the same time, thereby pushing the slider to move through the eccentric position, so that the two clamping claws are opened and the spring two is stretched at the same time. When the driving motor drives the rotary piece to reset, the clamping claws are pulled to move under the elastic force of the spring two, so that the two clamping claws clamp and correct the product. The limit block can limit the L-shaped block to prevent the corresponding spring one from pulling the rotary piece back. Under the action of the limit block, the L-shaped block is blocked to limit the middle protruding end of the rotary piece to prevent it from retreating to the corresponding slot-type photoelectric sensor, which affects the driving motor after power is turned on. It is mistakenly believed that the rotary piece correction is successful. At the same time, the end of the clamping claw that contacts the quartz substrate is made of soft material to avoid damage to the quartz substrate.

[0046] Figure 12-13 ,by Fig.12In the direction shown, the finished product unloading assembly includes a heating table C10 fixed on the rightmost material table A1 and an upper rack C14 located above the heating table C10, a heating plate C11 on the same horizontal line as the tray A7 is installed on the heating table C10, a heat insulation plate C12 located on the right side of the heating plate C11 is fixed on the top of the heating table C10, a plurality of concave surfaces C9 are formed on the side of the heat insulation plate C12 opposite to the corresponding tray A7, convex blocks C13 adapted to the concave surfaces C9 are formed on the left and right sides of the heating plate C11, and the convex blocks C13 are not in direct contact with the concave surfaces C9, a belt transmission device C15 is installed on the upper rack C14, and the upper rack C14 is also provided with a belt transmission device C15. A transverse plate C16 is slidably connected, one side of which is fixed to the belt of the second belt transmission device C15, and an upper cylinder C17 is also installed on the transverse plate C16, and an L-shaped plate C18 is fixed to the piston rod of the upper cylinder C17, and an upper plate C19 is fixed on the L-shaped plate C18. An opening is provided at the bottom of the right side of the upper plate C19, and a shift fork C24 is hinged on the inner side of the opening, a side block C20 is fixed to the right side of the upper plate C19, and a lower block C21 is fixed to the right side of the shift fork C24, and a compression spring C23 extending to the side block C20 is placed inside the lower block C21, and a screw C22 located above the compression spring C23 is threadedly connected to the top of the side block C20. The second belt transmission device can drive the horizontal plate to move left and right, so that the shift fork moves to the upper right side of the finished product, and the upper cylinder drives the L-shaped plate to move up and down, so that the shift fork can be moved to the right side of the finished product, and the cooperation of the second belt transmission device and the upper cylinder can make the shift fork move, move up, reset, move down and move, and the above operations are repeated to complete the shifting of the finished product to the heating plate. The finished product is pushed and transferred to the heating plate by the next finished product to be collected in the tray. When the finished product is unloaded, the finished product stays on the heating plate for a certain period of time, and the second belt transmission device drives the shift fork to move directly to the far left, so that The finished products on the heating plate can be moved to the tray for collection. The finished products are squeezed out forward in a queue and pass through the heating plate one by one, which prolongs the heating time. Only at the end of production, when the finished products on the heating plate are heated to the specified time, the finished products on the heating plate are emptied together through the shift fork. The compression spring passes through the side block and extends to the lower block. When it is screwed into the side block, the compression spring can be pressed down. Therefore, when the shift fork moves the finished product, the shift fork will contact the finished product and will retreat a certain distance, which will also make the compression spring bend, which can effectively avoid damage caused by hard contact between the shift fork and the finished product. At the same time, when the shift fork retreats, the elastic force of the compression spring can drive the shift fork to reset.

[0047] The working principle of the above embodiment is:

[0048] The lower shell and quartz substrate are manually placed in batches on the corresponding pallets, and then the pallet is placed on the carrier plate, and the pallet is limited by the stopper and the convex column. The linear cylinder drives the carrier plate to dock the pallet with the receiving table, the correction part and the heating plate respectively. After the docking is completed, the belt conveyor and the top cylinder drive the paddle to move to the end of the lower shell, and push the lower shell toward the receiving table until it moves onto the convex plate. At the same time, the horizontal linear module and the vertical linear module are operated to drive the adsorption block to transfer the quartz substrate to the upper block. The two drive motors move at the same time, and the drive motor drives the rotary piece to rotate, thereby driving the short rod to move. The short rod drives the L-shaped block and the rotating shaft to rotate respectively. Therefore, the L-shaped block drives the eccentric rod on the right to rotate. Under the linkage of the long rod, the other eccentric rod is driven through the hinge block. The center rod rotates, causing the eccentric rod to rotate to the side with the concave surface to contact the slider, so that the slider has space to retreat, and then under the elastic force of spring two, it will pull the clamping claws to clamp, and complete the correction processing on both sides of the quartz substrate. At the same time, the rotating shaft will drive the push block to rotate and retreat. At the same time, under the pulling force of spring three, the correction block will be pulled by bolt three to cooperate with the upper block to push the quartz substrate to correct. After the correction is completed, the front push cylinder is pushed out, and the fixed plate is driven forward through the connecting plate, so that the lower shell is located between the auxiliary clamping plate and the movable clamping plate. The push cylinder is pushed out, pushing the movable clamping plate to stretch the tension spring, and cooperating with the auxiliary clamping plate to clamp and fix the lower shell. Then the side push cylinder drives the side push plate to move, so that the lower shell moves to the bottom of the dispensing component, and the corresponding push clamp cylinder is pushed out to cooperate with the block to clamp and fix the lower shell. The push cylinder retreats, and the movable clamping plate is pulled back under the elastic force of the tension spring. At the same time, the front push cylinder and the side push cylinder are also reset and return to the starting point. The ejection cylinder drives the concave block to move downward, so that the glue needle of the hose moves to the next specified position, and then drives the concave block to move through the belt transmission device to complete the gluing operation. Then the fork conveying assembly resets and repeats the above operation, and moves the lower shell to the second set of push-clamp cylinders to complete the positioning. At this time, the adsorption block takes out the quartz substrate, and then moves to the boss to be vertically symmetrical with the lower shell. When assembling, the longitudinal linear module drives the vertical plate to move downward, and the drooping plate will always maintain the same height, and the downward pressing and fitting is completed by the gravity of the counterweight block. The fork conveying assembly moves the product to the bottom of the pressure-holding device for compaction, and then moves to the tail end of the boss, and then The rear belt transmission device 2 cooperates with the upper cylinder to move the fork to the right side of the finished product. The brief push of the belt transmission device 2 can push the finished product to the insulation board for pre-waiting. When the next finished product is pushed to the insulation board again through the above operation, the previous finished product will be moved to the heating plate under the guidance of the protrusion, and then the cycle operation can make the finished product pass through the heating plate and be collected on the tray guided by the protrusion. Therefore, the lower shell of the finished product and the quartz substrate can be bonded and cured on the heating plate by heat to improve the firmness. After the unloading is completed, there are some finished products. After the finished product is heated for a certain time, the fork is continuously driven to run to the left by the belt transmission device. Therefore, the finished products staying on the heating plate can pass through the heating plate and be pushed to the tray for collection.
