Description

Technical Field

[0001] This invention relates to the field of MPO connector processing technology, specifically to a multi-functional machine tool for processing MPO connectors. Background Technology

[0002] In the existing technology, the end face grinding process of MPO connectors usually requires multiple processes such as glue removal, rough grinding, fine grinding, and polishing. Each process requires the use of grinding paper with different mesh sizes, and the end face of the grinding disc is cleaned after each process to ensure the processing quality of the next process.

[0003] However, in existing equipment, the replacement of grinding paper and the cleaning of the grinding disc end face are mostly done manually. Operators need to manually tear off the old grinding paper, clean the residual adhesive and dust debris on the grinding disc end face, and then attach the new grinding paper. The process is cumbersome and time-consuming, making it difficult to meet the high efficiency requirements of mass production. At the same time, grinding paper is usually supplied in roll form, while grinding processing requires the use of round sheets that are compatible with the size of the grinding disc. Existing equipment lacks the function of automatically cutting the roll grinding paper into sheets and attaching them to the grinding disc. The cutting and attaching of grinding paper usually requires manual assistance, which not only increases the manual operation steps, but also makes it difficult to ensure the precise alignment and tight adhesion between the grinding paper and the grinding disc. It is easy to cause unstable grinding quality due to deviation in the attachment position or air bubbles. In addition, although some existing technologies have proposed automatic replacement structures for grinding paper, the grinding paper is always connected to both ends of the roll during the grinding process, which restricts the freedom of the grinding disc and makes it difficult to achieve complete composite motion, thereby affecting the flexibility of the grinding trajectory and the controllability of the processing quality.

[0004] Therefore, in view of this, the present invention proposes a multi-functional processing machine tool for MPO connectors to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a multi-functional processing machine tool for MPO connectors, thereby resolving the corresponding technical issues raised in the background section.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a multi-functional processing machine tool for MPO connectors, including a machine body, a grinding fixture provided on the machine body, a worktable fixedly connected to the center of the top of the machine body, a grinding disc provided on the worktable, and the grinding disc being located below the grinding fixture, and further including: a grinding end face finishing mechanism and a one-way cutting and separating mechanism, and both the grinding end face finishing mechanism and the one-way cutting and separating mechanism are provided on the machine body; The grinding end face cleaning mechanism includes a reciprocating lead screw, a moving block, an inverted U-shaped frame, a cleaning scraper, and grinding paper.

[0010] Preferably, a first connector is fixedly connected to the left side of one of the moving blocks, a first torsion spring shaft is rotatably connected to the upper surface of the machine body, a reel is fixedly connected to the outer surface of the upper end of the first torsion spring shaft, a traction rope is provided between the reel and the first connector, and the traction rope is wound on the reel, with the free end of the traction rope fixedly connected to the first connector.

[0011] Preferably, a drive gear is fixedly connected to the lower outer surface of the first torsion spring shaft, and a second torsion spring shaft is rotatably connected to the machine body. A driven gear is fixedly connected to the lower outer surface of the second torsion spring shaft, and the driven gear meshes with the drive gear. The diameter of the driven gear is larger than that of the drive gear.

[0012] Preferably, a top plate is fixedly connected to the top of the second torsion spring shaft, and a first cylinder is fixedly connected to the top of the end of the top plate away from the second torsion spring shaft. A pressure plate is fixedly connected to the output end of the first cylinder, and the pressure plate is used to press the abrasive paper onto the end face of the abrasive disc.

[0013] Preferably, a second fixing plate is symmetrically fixedly connected to the front side of the workbench, and a roller is rotatably connected between the second fixing plates.

[0014] Preferably, the worktable has symmetrical grooves on both sides, the movable block is fixedly connected to the side of the worktable facing the slider, and the slider is slidably connected in the groove. The rear wall of the groove is provided with a contact point, and the contact point is electrically connected to the first cylinder.

[0015] Preferably, the unidirectional cutting and separating mechanism further includes a bending frame fixedly connected between the second fixed plates, a unidirectional shaft rotatably connected to the bending frame, one of the unidirectional shafts being fixedly connected to a rotating rod through the bending frame, the unidirectional shaft being used to assist in pushing the abrasive paper, a second cylinder being fixedly connected at the top center of the bending frame, and the second cylinder being electrically connected to a contact point, a second connector being fixedly connected at the output end of the second cylinder, the second connector being fixedly connected at the top center of the cutting blade, the cutting blade being used to cut the abrasive paper.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) By setting up the grinding end face cleaning mechanism, and using the design of reciprocating screw, moving block, inverted U-shaped frame, cleaning scraper and grinding paper, the old grinding paper and adhesive dust remaining on the end face of the grinding disc can be scraped and cleaned during the process of the moving block driving the inverted U-shaped frame and cleaning scraper to slide back and forth along the worktable. At the same time as the cleaning scraper is cleaning, the inverted F-shaped frame pulls the grinding paper to lay on the upper surface of the grinding disc, and then presses it together and fixes it by the pressure plate. This realizes the integrated continuous operation of cleaning, pulling and pressing, and solves the problem of low efficiency and reliance on manual labor for grinding paper replacement and end face cleaning in the existing technology. It achieves the effect of reducing manual intervention, shortening paper replacement time and improving production efficiency. The clamping plate and threaded rod are designed to clamp and fix the free end of the abrasive paper, ensuring that the inverted F-shaped frame can stably pull the abrasive paper to unwind and spread from the roll as it moves with the inverted U-shaped frame.

[0017] (2) By setting up a one-way cutting and separating mechanism, and by using the design of a one-way shaft and a cutting blade, after the pressure plate presses the grinding paper onto the end face of the grinding disc, the cutting blade cuts and separates the waste material of the ring frame from the remaining grinding paper on the roll, and prevents the waste material from rewinding onto the roll during the resetting process. This solves the technical problem in the prior art where the grinding paper is always connected to both ends of the roll, which restricts the degree of freedom of the grinding disc. It achieves the effect of completely separating the grinding paper from the roll during the grinding process and ensuring that the grinding disc can perform complete composite motion. The unidirectional shaft design allows for one-way locking and positioning of the abrasive paper roll after the cutting blade has finished cutting, preventing the roll from deviating from its preset position due to inertial retraction and ensuring accurate and reliable traction starting position of the abrasive paper during the next paper change.

[0018] (3) Through the coordinated operation of the grinding end face sorting mechanism and the one-way cutting and separating mechanism, the circular grinding paper is cut and separated from the roll material by the annular protrusion on the lower edge of the pressure plate during the pressing process. Then, the waste material and the remaining roll material are further cut by the cutting knife. The entire process of cleaning, traction, pressing, cutting and separation is automated and closed-loop. This solves the problem that the grinding paper replacement requires manual cutting and bonding, the process is complicated and the consistency is poor. It achieves the effect of improving the paper replacement efficiency and grinding quality and ensuring the processing freedom of the grinding disc. Attached Figure Description

The clamping plate 525 is rotatably connected to the bottom of the threaded rod 526. An elastic telescopic column 527 is symmetrically fixedly connected between the upper surface of the clamping plate 525 and the inverted F-shaped frame 524. One of the movable blocks 504 is fixedly connected to the left side of a first connector 510. A first torsion spring shaft 512 is rotatably connected to the upper surface of the body 1. A reel 513 is fixedly connected to the outer surface of the upper end of the first torsion spring shaft 512. A traction rope 511 is provided between the reel 513 and the first connector 510, and the traction rope 511 is wound around the reel 513. The free end of the traction rope 511 is fixedly connected to the first connector 510. A drive gear 514 is fixedly connected to the outer surface of the lower end of the first torsion spring shaft 512. A second torsion spring shaft 515 is also rotatably connected to the body 1.

The front side of the workbench 3 is symmetrically fixed with a second fixing plate 521, and a roller 522 is rotatably connected between the second fixing plates 521. Abrasive paper 523 is wound around the outer surface of the roller 522, and the end of the abrasive paper 523 away from the roller 522 is clamped between the clamping plate 525 and the inner bottom wall of the inverted F-shaped frame 524. The workbench 3 has symmetrically arranged sliding grooves 506 on both sides. The moving block 504 is fixedly connected to the side of the workbench 3 with a slider 505, and the slider 505 is slidably connected in the sliding groove 506. The rear wall of the sliding groove 506 is provided with a contact point 507, and the contact point 507 is electrically connected to the first cylinder 518.

[0023] The effects achieved by this embodiment are as follows: Compared with the prior art, by setting up the grinding end face cleaning mechanism, and utilizing the design of the reciprocating screw 503, moving block 504, inverted U-shaped frame 509, cleaning scraper 520 and grinding paper 523, the old grinding paper and adhesive dust remaining on the end face of the grinding disc 4 can be scraped and cleaned during the process of the moving block 504 driving the inverted U-shaped frame 509 and cleaning scraper 520 to slide back and forth along the worktable 3. At the same time as the cleaning scraper 520 is cleaning, the inverted F-shaped frame 524 pulls the grinding paper 523 to lay it on the upper surface of the grinding disc 4, and then the pressure plate 519 presses and fixes it, realizing the integrated continuous operation of cleaning, pulling and pressing. This solves the problem of low efficiency and reliance on manual labor for grinding paper replacement and end face cleaning in the prior art, and achieves the effects of reducing manual intervention, shortening paper replacement time and improving production efficiency. The clamping plate 525 and the threaded rod 526 are designed to clamp and fix the free end of the abrasive paper 523, ensuring that the inverted F-shaped frame 524 can stably pull the abrasive paper 523 to unwind and spread from the winding shaft 522 when it moves with the inverted U-shaped frame 509.

[0024] Embodiment 2 of the present invention: Please refer to Figures 1 to 8 As shown, the one-way cutting and separating mechanism includes a one-way shaft 602 and a cutting blade 606. The one-way shaft 602 is symmetrically arranged on both sides of the abrasive paper 523, and the cutting blade 606 is arranged above the abrasive paper 523. The one-way cutting and separating mechanism is used to cut and separate the tail of the abrasive paper 523 pressed on the upper surface of the abrasive disc 4 from the roll material. The unidirectional cutting and separating mechanism also includes a bending frame 601 fixedly connected between the second fixed plates 521, a unidirectional shaft 602 rotatably connected to the bending frame 601, one of the unidirectional shafts 602 passing through the bending frame 601 and fixedly connected to a rotating rod 603, the unidirectional shaft 602 being used to assist in pushing the abrasive paper 523, a second cylinder 604 being fixedly connected at the top center of the bending frame 601, and the second cylinder 604 being electrically connected to a contact 507, a second connector 605 being fixedly connected at the output end of the second cylinder 604, the second connector 605 being fixedly connected at the top center of the cutting blade 606, the cutting blade 606 being used to cut the abrasive paper 523.

[0025] The effects achieved by this embodiment are as follows: Compared with the prior art, by setting up a one-way cutting and separating mechanism, and utilizing the design of the one-way shaft 602 and the cutting blade 606, after the pressure plate 519 presses the grinding paper 523 onto the end face of the grinding disc 4, the cutting blade 606 cuts and separates the annular frame waste from the remaining grinding paper 523 on the roll 522, and prevents the waste from rewinding onto the roll 522 during the resetting process. This solves the technical problem in the prior art where the grinding paper is always connected to both ends of the roll, which restricts the degree of freedom of the grinding disc 4. It achieves the effect of completely separating the grinding paper from the roll during the grinding process and ensuring that the grinding disc 4 can perform complete composite motion. The unidirectional shaft 602 enables the unidirectional locking and positioning of the roll portion of the abrasive paper 523 after the cutting blade 606 has finished cutting, preventing the roll from deviating from the preset position due to inertial retraction, and ensuring that the starting position of the traction of the abrasive paper 523 is accurate and reliable when the paper is changed next time. Furthermore, through the coordinated operation of the grinding end face sorting mechanism and the unidirectional cutting and separating mechanism, the circular grinding paper is cut and separated from the roll material during the pressing process by the annular protrusion at the lower edge of the pressure plate 519. Then, the cutting blade 606 further cuts the waste material and the remaining roll material, realizing an automated closed loop of the entire process of cleaning, traction, pressing, cutting, and separation. This solves the problem that the grinding paper replacement in the existing technology requires manual assistance in cutting and bonding, and the process is cumbersome and inconsistent. It achieves the effect of improving paper replacement efficiency and grinding quality, and ensuring the processing freedom of the grinding disc 4.

[0026] The complete usage steps and working principle of the above embodiments are as follows: In the initial state, such as Figure 1 and Figure 2 As shown, when the polishing paper is not replaced initially, the moving block 504 is located at the end of the reciprocating screw 503 near the drive motor 502 (i.e., the initial position), the inverted U-shaped frame 509 is located at the front end of the worktable 3, the cleaning scraper 520 is located in front of the polishing disc 4 and does not contact the polishing disc 4, and a whole roll of polishing paper 523 is wound on the spool 522. The free end of the polishing paper 523 passes through two one-way shafts 602 and continues to be stretched and clamped between the clamping plate 525 and the inner bottom wall of the inverted F-shaped frame 524. At this time, the pressure plate 519 is in a raised state under the drive of the first cylinder 518, located above the polishing disc 4 and not in contact with the polishing disc 4. The cutting blade 606 of the one-way cutting and separating mechanism is in a raised state, with a safe distance between it and the polishing paper 523. In addition, a collection box is provided on the rear side of the worktable 3 to collect the old polishing paper and adhesive residue scraped off by the cleaning scraper 520.

[0027] It should be noted in advance that, if Figure 1As shown, the grinding fixture 2 is used to connect the MPO connector, and the grinding disc 4 is used to grind the MOP connector. It should also be noted that the above-mentioned installation of the MPO connector on the grinding fixture 2 and the grinding process of the grinding disc 4 on the MOP connector are existing technologies and will not be elaborated on here.

[0028] The following describes the working process of the grinding end face cleaning mechanism for cleaning the end face of the grinding disc 4 and pulling the grinding paper 523 above the grinding disc 4: When using, such as Figures 1 to 5 As shown, the drive motor 502 is started to rotate forward first. The drive motor 502 drives the reciprocating screw 503 to rotate forward. Since the reciprocating screws 503 are connected by the transmission component 508, the two reciprocating screws 503 rotate synchronously. When the reciprocating screw 503 rotates, the moving block 504 on it moves away from the drive motor 502 along the reciprocating screw 503 under the action of the screw thread (i.e., moves to the rear end). When the moving block 504 moves, the slider 505 below it slides synchronously in the slide groove 506 of the worktable 3 to guide the movement of the moving block 504. As the moving block 504 moves backward, the inverted U-shaped frame 509 fixedly connected to the top of the moving block 504 moves backward in sync. During the movement of the inverted U-shaped frame 509, the cleaning scraper 520 fixedly connected to its inner top wall gradually approaches and passes the upper surface of the grinding disc 4 from the front. The cleaning scraper 520 scrapes away the old grinding paper, adhesive residue and dust debris remaining on the upper surface of the grinding disc 4. The scraped waste is pushed into the collection box on the back of the workbench 3 to achieve the end face cleaning function. Simultaneously, the inverted F-shaped frame 524 moves backward synchronously with the inverted U-shaped frame 509. The abrasive paper 523 is wound on the reel 522, with its free end clamped between the clamping plate 525 and the inner bottom wall of the inverted F-shaped frame 524. As the inverted F-shaped frame 524 moves backward, the free end of the abrasive paper 523 clamped therein is synchronously pulled backward. The abrasive paper 523 is passively unwound from the reel 522 and laid on top of the abrasive disc 4, covering the entire end face of the abrasive disc 4. It should be noted that the cleaning scraper 520 is an electrically telescopic plate and is electrically connected to the contact point 507. The cleaning scraper 520 initially has its maximum extension stroke, which can scrape the used old polishing paper off the polishing disc 4 during movement. When the contact 507 is touched and a signal is issued, it retracts, shortening its stroke and creating a gap between it and the end face of the polishing disc 4. The cleaning scraper 520 is located on the inner top wall of the inverted U-shaped frame 509. The new polishing paper 523 is laid on the upper surface of the polishing disc 4. The two are staggered in height, with the cleaning scraper 520 above the polishing paper 523. It will not scratch the polishing paper 523 during subsequent reset. The cleaning scraper 520 is an electrically telescopic plate and is electrically connected to the contact 507. When the contact 507 is triggered, the cleaning scraper 520 can retract to form a gap with the end face of the grinding disc 4, thus avoiding scratching the newly laid grinding paper 523 during the reset process. This ensures the cleaning effect while protecting the new paper. During the backward movement of the aforementioned moving block 504, since a first connector 510 is fixedly connected to one of the moving blocks 504, one end of the traction rope 511 is fixedly connected to the first connector 510, and the other end is wound around the reel 513. The moving block 504 pulls the traction rope 511 through the first connector 510. The traction rope 511 overcomes the torsion spring resistance of the first torsion spring shaft 512, causing the reel 513 to rotate and unwind. The traction rope 511 is pulled out of the reel 513, and the first torsion spring shaft 512... When rotating, the driving gear 514 at its lower end rotates synchronously. The driving gear 514 drives the driven gear 516 to rotate, and the driven gear 516 drives the second torsion spring shaft 515 to rotate. The second torsion spring shaft 515 drives the top plate 517 to rotate. Since the diameter of the driven gear 516 is larger than that of the driving gear 514, when the driving gear 514 rotates many times, the driven gear 516 only rotates a small angle, so as to achieve precise control of the rotation position of the top plate 517 and make the pressure plate 519 accurately rotate to the top of the grinding disc 4. When the moving block 504 moves to the end of its stroke (i.e., the cleaning scraper 520 has finished cleaning the upper surface of the grinding disc 4 and pushed the waste into the collection box, the grinding paper 523 has been laid to cover the upper surface of the grinding disc 4, and the pressure plate 519 has rotated to be directly above the grinding disc 4), the moving block 504 touches the contact point 507 on the rear wall of the slide 506. After the contact point 507 is triggered, it sends an electrical signal to the central controller. After receiving the electrical signal from contact 507, the central controller controls the first cylinder 518 to open because contact 507 is electrically connected to the first cylinder 518. The central controller drives the pressure plate 519 to move downward through its output end. The pressure plate 519 moves downward until it contacts the upper surface of the polishing paper 523 and continues to press down, pressing the polishing paper 523 tightly onto the upper surface of the polishing disk 4. During the pressing process, the flat lower end surface of the pressure plate 519 discharges the air between the polishing paper 523 and the polishing disk 4, so that the adhesive layer of the polishing paper 523 is fully adhered to the polishing disk 4. The lower edge of the pressure plate 519 is provided with an annular protrusion. The outline of the annular protrusion is adapted to the end face outline of the grinding disc 4. While the pressure plate 519 presses the grinding paper 523 onto the end face of the grinding disc 4, the annular protrusion cuts and separates the circular grinding paper sheet from the roll material along the pre-set dotted cutting line on the grinding paper 523. This allows the circular grinding paper sheet attached to the end face of the grinding disc 4 to be initially separated from the roll material. The remaining roll material after separation is the annular frame waste material after the circular sheet has been removed.

[0030] The following describes the working process of the unidirectional cutting and separating mechanism for cutting and separating the tail of the abrasive paper 523 pressed onto the upper surface of the abrasive disc 4 from the roll material: Since contact 507 is electrically connected to the second cylinder 604, and the starting sequence of the second cylinder 604 has a preset delay compared to the first cylinder 518, this delay is used to ensure that the pressing action between the polishing paper 523 and the polishing disc 4 is fully completed before the second cylinder 604 is started. After the preset delay, the central controller controls the second cylinder 604 to start running, and controls the second connector 605 to move down through its output terminal, thereby driving the cutting blade 606 to move down, so that the cutting blade 606 further cuts the separated roll tail (i.e. the connection between the annular frame waste and the remaining polishing paper 523 on the roll 522) along the width direction of the polishing paper 523, so that the waste is completely separated from the remaining polishing paper 523 on the roll 522. During the cutting process, since the one-way shaft 602 can only rotate in one direction along the unwinding direction of the abrasive paper 523, and is locked in the opposite direction, the remaining abrasive paper 523 on the roll 522 after cutting is locked and positioned by the one-way shaft 602 in one direction, and will not deviate from the preset position due to inertial retraction, ensuring that the starting position of the traction of the abrasive paper 523 is accurate and reliable when the paper is changed next time. After the cutting is completed, the central controller controls the second cylinder 604 to retract, and the cutting blade 606 to lift and reset. Then, the central controller controls the first cylinder 518 to retract, and the pressure plate 519 to lift and reset. Finally, the controller controls the drive motor 502 to reverse, and the moving block 504 moves to the front end along the reciprocating screw 503 to reset. During the reset process, since the waste material has been completely cut and separated from the remaining abrasive paper 523 on the roll 522, the waste material will not be rewound onto the roll 522 with the reset of the inverted F-shaped frame 524, so that the abrasive paper 523 can be replaced later. After the equipment stops running, the operator can loosen the clamping plate 525 by rotating the threaded rod 526, remove the waste material, and then re-clamp the free end of the grinding paper 523 between the clamping plate 525 and the inner bottom wall of the inverted F-shaped frame 524 to complete a complete work cycle. The above process is repeated when the paper is changed next time.
