Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for optical module production, specifically a pressing and holding fixture after optical module chip mounting. Background Technology

[0002] In the production of optical modules, chip mounting is one of the key processes. After the chip is mounted onto the optical module substrate using solder or adhesive, a pressing and holding fixture is needed to apply stable pressure to the chip until the solder cures or the adhesive dries, ensuring the connection strength and stability between the chip and the substrate. In existing technologies, the pressing and holding fixtures after chip mounting are mostly integrated fixed structures with fixed dimensions and shapes of their pressure-holding components. These fixtures can only be adapted to a single type of optical module chip. When producing different types of optical modules, the entire pressing and holding fixture needs to be replaced, which not only increases the cost of production equipment but also prolongs the fixture changeover time and reduces production efficiency.

[0003] Meanwhile, the existing press-holding fixture has a cumbersome operating procedure. When placing or removing the optical module, it is usually necessary to release the pressure holding state through multiple bolts or buckle structures, which involves many steps and is time-consuming. In addition, the pressure holding mechanism of some fixtures lacks effective guiding and limiting structures, which can easily lead to pressure deviation or instability during the pressure holding process. This can cause the chip mounting position to be misaligned or the connection to be loose, affecting the product quality of the optical module and making it difficult to meet the needs of large-scale mass production.

[0004] Therefore, a pressing and holding fixture after the optical module chip is mounted is proposed to solve the above-mentioned problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a pressing and holding fixture for mounting optical module chips, which has the advantages of strong adaptability, convenient operation, and stable pressure holding. It solves the problems of poor adaptability, cumbersome operation, and insufficient pressure holding stability of existing optical module chip mounting pressing and holding fixtures.

[0007] (II) Technical Solution

[0008] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A pressing and holding fixture after mounting an optical module chip includes a frame, a pressure holding box is fixedly connected to the inner side of the frame, a reset mechanism is provided at the top of the frame with one end extending to the inner side of the frame, a pressure holding cover plate adapted to the pressure holding box is fixedly connected to the bottom of the reset mechanism, and a snap-fit ​​mechanism adapted to the frame is fixedly connected to the top of the pressure holding cover plate.

[0009] The pressure-holding box and pressure-holding cover are used to press and hold the optical module chip;

[0010] The reset mechanism includes a slide rod fixedly connected to the top of the pressure-holding cover plate. The top of the slide rod extends to the top of the frame. A pressing plate is fixedly connected to the top of the slide rod. The top of the pressing plate is arc-shaped. The bottom of the pressing plate and the top of the frame are fixedly connected to the same reset spring located outside the slide rod.

[0011] The reset mechanism can cause the pressure-holding cover to separate from the pressure-holding box after the snap-fit ​​mechanism is separated.

[0012] The beneficial effects of this utility model are:

[0013] This pressure-holding fixture for optical module chip mounting features a replaceable pressure-holding box and pressure-holding cover design, making it compatible with different models of optical module chips and reducing fixture replacement costs. The combination of a reset mechanism and a snap-fit ​​mechanism simplifies the switching operation of the pressure-holding state, improving operational convenience. Simultaneously, the guide structure ensures stable and precise pressure during the pressure-holding process, effectively improving chip mounting quality. It boasts advantages such as strong adaptability, convenient operation, and stable pressure holding.

[0014] Based on the above technical solution, the present invention can be further improved as follows.

[0015] Furthermore, the frame is a U-shaped frame, and the top and inner sides of the frame are fixedly connected with guide rings that are sleeved on the outside of the slide rod and adapted to the slide rod.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the guide ring can accurately limit the up and down sliding trajectory of the slide bar, prevent the slide bar from shifting left and right during the movement, and ensure that the pressure holding cover plate always remains coaxially aligned with the pressure holding box when moving up and down, thereby ensuring that the pressure on the optical module chip is uniform and improving the stability and accuracy of the press holding.

[0017] Furthermore, the pressure-holding box includes an outer box, which is fixedly connected to the inside of the frame. The left side of the outer box is open, and an inner box is slidably connected inside the outer box. The inner box is adapted to the bottom of the optical module, and the inner box can be replaced according to the optical module model. A handle is fixedly connected to the left side of the inner box.

[0018] The advantages of adopting the above-mentioned further solutions are that the outer box provides a stable installation and sliding foundation for the inner box, the inner box can be customized and replaced according to the size of different optical modules, without the need to replace the entire pressure box, which greatly reduces the cost of tooling use and maintenance; the handle allows operators to easily pull out the inner box, which facilitates the quick placement or removal of optical modules, reduces operation time, and improves production efficiency.

[0019] Furthermore, the pressure-holding cover includes a mounting plate, which is fixedly connected to the bottom of the slide rod. Two slide rails, symmetrically distributed front and back, are fixedly connected to the bottom of the mounting plate. A pressure-holding plate is slidably connected between the two slide rails. A pull-out knob, which is slidably connected to the mounting plate and extends above the mounting plate, is fixedly connected to the top of the pressure-holding plate. A fixing screw, which passes through the mounting plate and extends into the pressure-holding plate, is threadedly connected to the top of the mounting plate and the top of the pressure-holding plate. A knob with an anti-slip groove on the outside is fixedly connected to the top of the fixing screw.

[0020] The advantages of adopting the above-mentioned further solution are that the mounting plate provides a mounting carrier for the various components of the pressure-holding cover, the slide rail provides a sliding guide for the pressure-holding plate to ensure that the pressure-holding plate can be smoothly installed and removed; the pull-out knob allows operators to quickly pull out the pressure-holding plate, making it easy to replace the appropriate pressure-holding plate according to the optical module model; the fixing screws can firmly fix the pressure-holding plate to the mounting plate to prevent the pressure-holding plate from loosening during the pressure-holding process; the anti-slip groove on the outside of the knob can increase the friction between the hand and the knob, making it easy for operators to quickly tighten or loosen the fixing screws, further improving the ease of operation.

[0021] Furthermore, both slide rails are L-shaped, the top of the mounting plate has a groove adapted to the pull-out torque, the groove and the left side of both slide rails are open, and the pressure plate and the mounting plate are both internally threaded to match the fixing screw.

[0022] The advantages of adopting the above-mentioned further solution are that the L-shaped slide rail can simultaneously limit the pressure plate in both the vertical and horizontal directions, preventing the pressure plate from shifting or falling off during sliding or pressure holding; the slide groove provides movement space for the pull-out knob, ensuring that the pressure plate can be smoothly pulled along the slide rail; the open slide groove and slide rail facilitate the quick assembly and disassembly of the pressure plate; the internal thread can ensure the thread connection strength between the fixing screw and the pressure plate and mounting plate, further improving the fixing stability of the pressure plate.

[0023] Furthermore, the snap-fit ​​mechanism includes a top plate and two snap-fit ​​slots, which are respectively opened on the left and right sides of the frame. The top plate is fixedly connected to the top of the mounting plate and located outside the slide rod. The bottom of the top plate is fixedly connected to two mounting boxes that are symmetrically distributed on both sides of the mounting plate. Push plates are slidably connected inside the two mounting boxes. A snap-fit ​​block that passes through the mounting box and matches the snap-fit ​​slot on the same side is fixedly connected to the opposite side of the two push plates. Two ejection springs that are symmetrically distributed vertically are fixedly connected between the opposite side of the two push plates and the mounting box on the same side. Two guide blocks that match the push plates on the same side are fixedly connected inside the two mounting boxes.

[0024] In the unpressurized state, the pressure-holding cover is in the upper position under the action of the return spring, and the locking block is always in contact with the inner side of the frame and subjected to its continuous squeezing force. The ejector spring is in a compressed state, and the locking block is completely retracted inside the mounting box. When the pressure-holding cover is fully pressed down to the pressure-holding position, that is, when the pressure-holding plate is attached to the optical module chip and a preset pressure is applied, the locking block moves to the position corresponding to the locking slot. The squeezing force of the frame on the locking block disappears, the ejector spring returns to its original position and pushes the push plate, so that the locking block is embedded in the locking slot on the same side to achieve pressure holding and fixation.

[0025] The beneficial effects of adopting the above-mentioned further solutions are as follows: the top plate provides a stable mounting base for the mounting box; the snap-fit ​​groove provides a precise embedding position for the snap-fit ​​block during pressure holding; the mounting box provides a closed protective space for the push plate, ejection spring, and guide block, preventing impurities from affecting the operation of the components; when not under pressure, the frame continuously squeezes the snap-fit ​​block to shrink it, which can prevent the pressure holding cover from accidentally triggering the snap-fit ​​and ensure the stability of the tooling state when the optical module is picked up and placed; after the pressure holding cover is fully pressed down, it automatically releases the squeeze and triggers the snap-fit, requiring no additional operation and simplifying the pressure holding process; the guide block limits the sliding trajectory of the push plate, ensuring that the snap-fit ​​block is accurately embedded in the snap-fit ​​groove and improving the reliability of pressure holding and locking.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] In the embodiments, by Figure 1-4 The present invention provides a pressing and holding fixture for mounting optical module chips. The present invention includes a frame 1, a pressure holding box 2 fixedly connected to the inner side of the frame 1, a reset mechanism 3 with one end extending to the inner side of the frame 1 provided on the top of the frame 1, a pressure holding cover plate 4 adapted to the pressure holding box 2 fixedly connected to the bottom of the reset mechanism 3, and a snap-fit ​​mechanism 5 adapted to the frame 1 fixedly connected to the top of the pressure holding cover plate 4.

[0033] Pressure holding box 2 and pressure holding cover 4 are used to press and hold the optical module chip;

[0034] The reset mechanism 3 includes a slide bar 301 fixedly connected to the top of the pressure holding cover plate 4. The top of the slide bar 301 extends to the top of the frame 1. A pressing plate 302 is fixedly connected to the top of the slide bar 301. The top of the pressing plate 302 is arc-shaped. The bottom of the pressing plate 302 and the top of the frame 1 are fixedly connected to the same reset spring 303 located outside the slide bar 301.

[0035] The reset mechanism 3 can separate the pressure holding cover 4 from the pressure holding box 2 after the locking mechanism 5 is separated;

[0036] The frame 1 is a U-shaped frame. The top and inner side of the frame 1 are fixedly connected with guide rings 6 that are sleeved on the outside of the slide rod 301 and adapted to the slide rod 301.

[0037] The guide ring 6 can precisely limit the up and down sliding trajectory of the slide bar 301, preventing the slide bar 301 from shifting left and right during movement, ensuring that the pressure holding cover 4 always remains coaxially aligned with the pressure holding box 2 when moving up and down, thereby ensuring that the pressure on the optical module chip is uniform and improving the stability and accuracy of the press holding.

[0038] The pressure-holding box 2 includes an outer box 201, which is fixedly connected to the inside of the frame 1. The left side of the outer box 201 is open. An inner box 202 is slidably connected inside the outer box 201. The inner box 202 is adapted to the bottom of the optical module. The inner box 202 can be replaced according to the optical module model. A handle 203 is fixedly connected to the left side of the inner box 202.

[0039] The outer box 201 provides a stable mounting and sliding base for the inner box 202. The inner box 202 can be customized and replaced according to the size of different optical modules without replacing the entire pressure box 2, which greatly reduces the cost of tooling use and maintenance. The handle 203 allows operators to easily pull out the inner box 202, which facilitates the quick placement or removal of optical modules, reduces operation time, and improves production efficiency.

[0040] The pressure holding cover plate 4 includes a mounting plate 401, which is fixedly connected to the bottom of the slide bar 301. The bottom of the mounting plate 401 is fixedly connected to two slide rails 402 that are symmetrically distributed front and back. The same pressure holding plate 403 is slidably connected between the two slide rails 402. The top of the pressure holding plate 403 is fixedly connected to the mounting plate 401 and extends to the top of the mounting plate 401 with a pull-out knob 404. The top of the mounting plate 401 and the top of the pressure holding plate 403 are threadedly connected to the same fixing screw 405 that passes through the mounting plate 401 and extends into the interior of the pressure holding plate 403. The top of the fixing screw 405 is fixedly connected to a knob 406 with an anti-slip groove on the outside.

[0041] Mounting plate 401 provides a mounting carrier for the various components of pressure holding cover plate 4; slide rail 402 provides a sliding guide for pressure holding plate 403, ensuring that pressure holding plate 403 can be smoothly installed and removed; pull knob 404 allows operators to quickly pull out pressure holding plate 403, facilitating the replacement of the appropriate pressure holding plate 403 according to the optical module model; fixing screw 405 can firmly fix pressure holding plate 403 to mounting plate 401, preventing pressure holding plate 403 from loosening during pressure holding; the anti-slip groove on the outside of knob 406 can increase the friction between the hand and knob 406, making it easy for operators to quickly tighten or loosen fixing screw 405, further improving the ease of operation;

[0042] Both slide rails 402 are L-shaped. The top of the mounting plate 401 is provided with a slide groove 7 that matches the pull-out knob 404. The slide groove 7 and the left side of both slide rails 402 are open. The pressure plate 403 and the mounting plate 401 are both provided with internal threads that match the fixing screws 405.

[0043] The L-shaped slide rail 402 can simultaneously limit the pressure plate 403 in both the vertical and horizontal directions, preventing the pressure plate 403 from shifting or falling off during sliding or pressure holding. The slide groove 7 provides movement space for the pull-out knob 404, ensuring that the pressure plate 403 can be smoothly pulled along the slide rail 402. The open slide groove 7 and slide rail 402 facilitate the quick assembly and disassembly of the pressure plate 403. The internal thread can ensure the thread connection strength between the fixing screw 405 and the pressure plate 403 and the mounting plate 401, further improving the fixing stability of the pressure plate 403.

[0044] The snap-fit ​​mechanism 5 includes a top plate 501 and two snap-fit ​​slots 502. The two snap-fit ​​slots 502 are respectively opened on the left and right sides of the frame 1. The top plate 501 is fixedly connected to the top of the mounting plate 401 and is located outside the slide rod 301. The bottom of the top plate 501 is fixedly connected to two mounting boxes 503 that are symmetrically distributed on both sides of the mounting plate 401. Push plates 504 are slidably connected inside the two mounting boxes 503. The opposite sides of the two push plates 504 are fixedly connected to a snap-fit ​​block 505 that passes through the mounting box 503 and is adapted to the snap-fit ​​slot 502 on the same side. The opposite sides of the two push plates 504 and the mounting box 503 on the same side are fixedly connected to two ejector springs 506 that are symmetrically distributed vertically. The inside of the two mounting boxes 503 is fixedly connected to two guide blocks 507 that are adapted to the push plates 504 on the same side.

[0045] In the non-pressure-holding state, the pressure-holding cover 4 is in the upper position under the action of the return spring 303, and the locking block 505 is always in contact with the inner side of the frame 1 and subjected to its continuous squeezing force. The ejector spring 506 is in the compressed state, and the locking block 505 is completely retracted inside the mounting box 503. When the pressure-holding cover 4 is fully pressed down to the pressure-holding position, that is, when the pressure-holding plate 403 is attached to the optical module chip and a preset pressure is applied, the locking block 505 moves to the position corresponding to the locking groove 502. The squeezing force of the frame 1 on the locking block 505 disappears, the ejector spring 506 resets and pushes the push plate 504, so that the locking block 505 is embedded in the locking groove 502 on the same side to achieve pressure holding and fixation.

[0046] The top plate 501 provides a stable mounting base for the mounting box 503, and the snap-fit ​​groove 502 provides a precise embedding position for the snap-fit ​​block 505 during pressure holding. The mounting box 503 provides a closed protective space for the push plate 504, the ejection spring 506, and the guide block 507 to prevent impurities from affecting the operation of the components. When pressure is not being held, the frame 1 continuously squeezes the snap-fit ​​block 505 to make it retract, which can prevent the pressure holding cover plate 4 from accidentally triggering the snap-fit ​​and ensure the stability of the tooling state when the optical module is picked up and put down. After the pressure holding cover plate 4 is fully pressed down, it automatically releases the squeeze and triggers the snap-fit, without the need for additional operation, simplifying the pressure holding process. The guide block 507 limits the sliding trajectory of the push plate 504 to ensure that the snap-fit ​​block 505 is accurately embedded in the snap-fit ​​groove 502, improving the reliability of pressure holding and locking.

[0047] Working principle:

[0048] Step 1: Select the appropriate inner box 202 and pressure plate 403 according to the model of the optical module to be processed; slide the inner box 202 into the outer box 201 through the opening on the left side of the outer box 201 to complete the installation of the inner box 202; place the optical module to be mounted with the chip into the inner box 202; then slide the pressure plate 403 into the space between the two slide rails 402 along the open end of the slide rail 402, so that the pull-out knob 404 slides in the slide groove 7 until the pressure plate 403 is aligned with the threaded hole on the mounting plate 401, turn the knob 406 to drive the fixing screw 405 into the threaded hole, and fix the pressure plate 403 on the mounting plate 401; at this time, the pressure cover plate 4 is in the upper position under the action of the return spring 303, and the locking block 505 of the locking mechanism 5 is always in contact with the inner side of the frame 1 and is squeezed, and is completely retracted into the mounting box 503;

[0049] Step 2: Press down continuously on the pressing plate 302. The pressing plate 302 compresses the reset spring 303 and drives the slide rod 301 to slide down along the guide ring 6. The slide rod 301 simultaneously drives the pressure holding cover plate 4 to move vertically downward. During the downward movement, the locking block 505 always remains in contact with the inner side of the frame 1 and is squeezed. The ejector spring 506 continues to compress, and the locking block 505 remains in a contracted state. Continue pressing down until the pressure holding plate 403 is completely attached to the optical module chip in the inner box 202 and a preset pressure holding pressure is applied. At this time, the pressure holding cover plate 4 reaches the fully pressed pressure holding position, and the locking block 505 moves exactly to the position corresponding to the snap-fit ​​groove 502 on the frame 1. The squeezing force of the frame 1 on the locking block 505 disappears instantly. The ejector spring 506 quickly resets, pushes the push plate 504 to slide outward, and drives the locking block 505 to be embedded in the snap-fit ​​groove 502, completing the pressure holding state locking. The pressure holding plate 403 continuously applies stable pressure to the chip.

[0050] Step 3: After the optical module chip has been cured, i.e. the solder has cured or the adhesive has dried, press the two side locking blocks 505 inward. The locking blocks 505 push the push plate 504 to compress the spring 506 until the locking blocks 505 are completely disengaged from the locking groove 502 and retract back into the mounting box 503. At this time, the reset spring 303 loses its pressing force and resets, pushing the pressing plate 302 to move upward. The pressing plate 302 drives the pressure holding cover 4 to rise and reset through the slide rod 301, and the pressure holding plate 403 separates from the optical module chip. Finally, pull the handle 203 to pull the inner box 202 out of the outer box 201, take out the optical module that has completed the pressure holding, and complete one pressing and holding operation.
