Description

Technical Field

[0001] This invention belongs to the field of optical communication technology, and in particular relates to a non-destructive repair device for LENS and its repair method. Background Technology

[0002] Traditional collimating devices with lenses often exhibit poor performance during spot testing, leading to cumbersome rework processes. This requires disassembling and separating individual components, grinding solder joints, and replacing parts. Lens-based collimating devices are typically expensive, and the rework process can easily damage the lenses, rendering them unusable and increasing production costs. Summary of the Invention

[0003] To address the problem that traditional LENS rework methods require disassembly, which can easily cause surface defects and damage, leading to unacceptable parts that must be scrapped and increased production costs, this invention provides a non-destructive LENS repair device and method.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A non-destructive repair device and method for lenses include a base plate. One side of the base plate has a groove with a sliding plate slidably connected within it. The other side has a placement groove for connecting a grating ruler. A digital display is connected to the side of the sliding plate closest to the grating ruler to display the sliding plate's movement distance. A fixing seat is located at one end of the top of the base plate, with a fine-tuning screw threaded through it to push the sliding plate. A locking seat is located at the other end of the top of the base plate, with a stop block on the side of the locking seat away from the sliding plate for engaging with a stop card and a through card to engage the lens body. A push block is located at the end of the sliding plate closest to the locking seat for engaging with the locking seat to lengthen or shorten the lens body.

[0006] Preferably, the card holder is provided with a wide card slot and a narrow card slot, the depth of the wide card slot is lower than the depth of the narrow card slot, and the wide card slot is close to the push block; the wide card slot is used to place a penetrating card, and the narrow card slot is used to place a penetrating card or a stop card.

[0007] Preferably, the push block has a boss at one end near the card slot, the width of the boss being smaller than the width of the narrow card slot; four pushers are inserted into the boss in a square arrangement, and the distance between two adjacent pushers is greater than the diameter of the end of the LENS body.

[0008] Preferably, there are two penetrating cards and two stopping cards, each with a second semicircular groove and a first semicircular groove in the middle for engaging the LENS body. Each penetrating card has two through holes with the same diameter as the pusher diameter. The distance between the two through holes is equal to the distance between two adjacent pushers. After the second semicircular grooves on the two penetrating cards are fitted together, the distance between two adjacent through holes on the two penetrating cards is also equal to the distance between two adjacent pushers.

[0009] Preferably, the long side of the penetrating card is the same as the width of the wide card slot, and the short side is half the depth of the wide card slot; the long side of the stop card is the same as the width of the narrow card slot, and the short side is half the depth of the narrow card slot.

[0010] Preferably, the stop block is screwed with two limiting screws, which are symmetrically distributed on both sides of the narrow slot and can penetrate the slot seat, for limiting the movement distance of the push block.

[0011] Preferably, both ends of the top of the base plate are provided with leveling blocks for pressing and leveling the grating ruler.

[0012] The repair method for the above-mentioned non-destructive repair device for lenses, when requiring the lens body to be stretched for repair, includes the following steps:

[0013] S1. First, place a penetrating card with the second semicircular groove facing upward in the wide slot, and then place a stop card with the first semicircular groove facing upward in the narrow slot. Next, place the LENS body on the penetrating card and the stop card, so that the second semicircular groove is located at the step part on the LENS body, and the first semicircular groove is located on the side of the flange near the penetrating card. Then, place the second penetrating card and the stop card on top of the LENS body to support the LENS body.

[0014] S2. Tighten the fine-tuning screw. The fine-tuning screw pushes the slide plate and the push block on it to move closer to the card seat. The pusher on the push block passes through the through hole on the penetrating card until the end of the pusher touches the stop card. At this time, operate the zeroing button on the digital display to reset the reading to zero. Then tighten the fine-tuning screw again to push the slide plate and the push block on it to move. The pusher pushes the stop card and the LENS body on one side to move. The penetrating card locks the step part of the LENS body, so that the coupling part of the LENS body is stretched.

[0015] S3. Determine whether the LENS body has been stretched and repaired according to the reading on the digital display. After stretching and repairing, turn the fine adjustment screw in the opposite direction to reset it, then slide the slide plate and the push block on it to reset. Then you can take out the penetrating card and the stop card on the top of the LENS body, and then take out the repaired LENS body.

[0016] The repair method for the above-mentioned non-destructive repair device for lenses requires shortening the repair time of the lens body and includes the following steps:

[0017] S1. First, rotate a penetrating card 90° so that the second semicircular groove faces the front or back and place it in the narrow card slot. Then, insert the stepped part of the LENS body into the second semicircular groove and put another penetrating card into the narrow card slot to support the LENS body.

[0018] S2. Tighten the fine-tuning screw. The fine-tuning screw pushes the slide plate and the push block on it to move closer to the card seat. The pusher on the push block passes through the through hole on the card until the boss on the push block abuts against the end of the LENS body. Then, tighten the fine-tuning screw again to push the slide plate and the push block on it to move, pushing the card and the LENS body to move so that the end away from the boss abuts against the stop. At this time, operate the zeroing button on the digital display to reset the reading to zero. Then tighten the fine-tuning screw again to push the slide plate and the push block on it to move. The boss and the stop cooperate to squeeze the LENS body, so that the coupling part of the LENS body is shortened.

[0019] S3. Determine whether the LENS body has been shortened and repaired according to the reading on the digital display. After the shortening and repair are in place, turn the fine adjustment screw in the opposite direction to reset it, then slide the slide plate and the push block on it to reset it. Then you can take out the repaired LENS body and the penetrating card.

[0020] Preferably, based on the length of the LENS body that needs to be lengthened or shortened for repair, the position of the end of the limit screw is first adjusted. When the reading of the digital display returns to zero, the distance between the end of the push block and the end of the limit screw is the length of the LENS body that needs to be lengthened or shortened for repair, in order to avoid over-repair.

[0021] Compared with existing technologies, the advantages of this invention are as follows: This invention overcomes the shortcomings of previous rework techniques, enabling precise correction of the LENS length without disassembling the LENS, thereby fixing the LENS spot size problem. During the repair process, four pushers are used to pass through the penetration card. When elongating the LENS body for repair, the four pushers simultaneously push from the top, bottom, left, and right sides, ensuring the LENS body remains stable during repair and preventing concentricity deviation caused by unilateral pushing. When repairing LENS bodies of different specifications, components such as pushers, card holders, stop cards, and penetration cards can be replaced accordingly, and limiting screws are used for positioning. This allows for repair of LENS bodies of different specifications, and the movement range of the pushers can be limited at any time to avoid over-repair due to excessive movement.

[0031] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] like Figures 1 to 6 As shown, this embodiment of the invention includes a base plate 1. A groove 5 is formed on one side of the base plate 1, and a slide plate 6 is slidably connected in the groove 5. A placement groove 4 is provided on the other side for attaching a grating ruler 13. A digital display 7 is connected to the side of the slide plate 6 near the grating ruler 13 for displaying the movement distance reading of the slide plate 6. The digital display 7 can be customized according to requirements, and its principle is the same as that of an electronic digital caliper. A fixing seat 2 is provided at one end of the top of the base plate 1. A fine adjustment screw 3 is screwed through the fixing seat 2 for pushing the slide plate 6 to move. A locking seat 9 is provided at the other end of the top of the base plate 1. A stop block 10 is provided on the side of the locking seat 9 away from the slide plate 6 for engaging with a stop card 15 and a penetrating card 16 to engage the LENS body 12. A push block 8 is provided at the end of the slide plate 6 near the locking seat 9 for engaging with the locking seat 9 to lengthen or shorten the LENS body 12.

[0034] Preferably, the card holder 9 is provided with a wide card slot 901 and a narrow card slot 902. The depth of the wide card slot 901 is lower than the depth of the narrow card slot 902, and the wide card slot 901 is close to the push block 8. The wide card slot 901 is used to place the penetrating card 16, and the narrow card slot 902 is used to place the penetrating card 16 or the stop card 15. The push block 8 is provided with a boss 801 at one end near the card holder 9. The width of the boss 801 is smaller than the width of the narrow card slot 902. Four pushers 802 are inserted into the boss 801 in a square distribution, and the distance between two adjacent pushers 802 is greater than the diameter of the end of the LENS body 12.

[0035] There are two penetrating cards 16 and two stopping cards 15, with a second semicircular groove 1602 and a first semicircular groove 1501 respectively in the middle for engaging the LENS body 12; the penetrating card 16 has two through holes 1601, and the diameter of the through holes 1601 is the same as the diameter of the pusher 802. The distance between the two through holes 1601 is equal to the distance between two adjacent pushers 1601. After the second semicircular grooves 1602 on the two penetrating cards 16 are attached to each other, the distance between two adjacent through holes 1601 on the two penetrating cards 16 is also equal to the distance between two adjacent pushers 802.

[0036] The long side of the penetrating card 16 is the same as the width of the wide card slot 801, and the short side is half the depth of the wide card slot 801; the long side of the stop card 15 is the same as the width of the narrow card slot 802, and the short side is half the depth of the narrow card slot 802; two limiting screws 11 are screwed onto the stop block 10, and the two limiting screws 11 are symmetrically distributed on both sides of the narrow card slot 802 and can penetrate the card seat 9, which are used to limit the movement distance of the push block 8; leveling blocks 14 are provided at both ends of the top of the base plate 1, which are used to press and level the grating ruler 13.

[0037] like Figure 7As shown, when it is necessary to stretch and repair the LENS body 12, the following steps are included:

[0038] First, place a penetrating card 16 in the wide slot 801 with the second semicircular groove 1602 facing upwards. Then, place a stop card 15 in the narrow slot 802 with the first semicircular groove 1501 facing upwards. Next, place the LENS body 12 on the penetrating card 16 and the stop card 15, so that the second semicircular groove 1602 is located at the step portion 1202 on the LENS body 12, and the first semicircular groove 1501 is located on the side of the flange portion 1203 near the penetrating card 16. Then, place the second penetrating card 16 and the stop card 15 on top of the LENS body 12 to support the LENS body 12.

[0039] Turn the fine-tuning screw 3 again. The fine-tuning screw 3 pushes the slide plate 6 and the push block 8 on it to move closer to the card seat 9. The pusher 802 on the push block 8 passes through the through hole 1601 on the penetrating card 16 until the end of the pusher 802 abuts against the stop card 15. At this time, operate the zeroing button on the digital display 7 to make the reading zero. Then turn the fine-tuning screw 3 again to push the slide plate 6 and the push block 8 on it to move again. The pusher 6 pushes the stop card 15 and the LENS body 12 on one side to move. The penetrating card 16 locks the step part 1202 of the LENS body 12, so that the coupling part 1201 of the LENS body 12 is stretched.

[0040] When the end of the push block 8 touches the end of the limit screw 11, the reading on the digital display 7 is used to determine whether the LENS body 12 has been stretched and repaired in place. After the stretching and repair is in place, the fine-tuning screw 3 is turned in the opposite direction to reset it. Then the sliding plate 6 and the push block 8 on it are reset. Then the penetrating card 16 and the stop card 15 on the top of the LENS body 12 can be removed, and the repaired LENS body 12 can be removed.

[0041] like Figure 8 As shown, when it is necessary to shorten and repair the LENS body 12, the following steps are included:

[0042] First, rotate a penetrating card 16 90° so that the second semicircular groove 1602 faces the front or back and is placed in the narrow card slot 802. Then, insert the stepped part 1202 of the LENS body 12 into the second semicircular groove 1602 and place another penetrating card 16 into the narrow card slot 802 to support the LENS body 12.

[0043] Turn the fine-tuning screw 3, and the fine-tuning screw 3 will push the slide plate 6 and the push block 8 on it to move closer to the card seat 9. The pusher 802 on the push block 8 will pass through the through hole 1602 on the penetrating card 16 until the boss 801 on the push block 8 abuts against the end of the LENS body 12. Then turn the fine-tuning screw 3 again, and push the slide plate 6 and the push block 8 on it to move, pushing the penetrating card 16 and the LENS body 12 to move away from the end of the boss 801 and abut against the stop block 10. At this time, operate the zeroing button on the digital display 7 to reset the reading to zero. Then turn the fine-tuning screw 3 again, and push the slide plate 6 and the push block 10 on it to move again. The boss 801 and the stop block 10 cooperate to squeeze the LENS body 12, so that the coupling part 1201 of the LENS body 12 is shortened.

[0044] When the end of the push block 8 touches the end of the limit screw 11, the reading on the digital display 7 is used to determine whether the LENS body 12 has been shortened and repaired. After the shortening and repair is completed, the fine adjustment screw 3 is turned in the opposite direction to reset it. Then the sliding plate 6 and the push block 8 on it are reset. Then the repaired LENS body 12 and the penetrating card 16 can be taken out.

[0045] During the repair process, four pushers 802 are used to pass through the penetration card 16. When the LENS body 12 is stretched for repair, the four pushers 802 push simultaneously from the top, bottom, left, and right sides, ensuring that the LENS body 12 does not tilt during the repair process and avoiding concentricity deviation caused by pushing from one side. When repairing LENS bodies 12 of different specifications, the pusher 8, card holder 9, stop card 15, and penetration card 16 can be replaced accordingly, and the limit screw 11 is used for limiting. This method can also be used to repair LENS bodies 12 of different specifications. The movement range of the pusher 8 can be limited at any time to avoid over-repair caused by excessive movement.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
