[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0028] In the present invention, the descriptions of directions such as "up", "down", "front", "back", "left", and "right" are as follows: Figure 1 The directions shown are for reference only and are used to explain the Figure 1 The relative position relationship between the components in the shown posture. If the specific posture changes, the directional indication will also change accordingly.

[0029] At present, in the production stage of optical modules, optical devices and PCBs are mainly coupled through automated coupling devices. However, in the research and development stage of optical modules or the later solution optimization stage, the selection of optical devices or PCBs needs to be frequently changed. If an automated coupling device is used, multiple mold openings are required, resulting in high mold opening costs. Manual coupling methods are difficult to ensure accurate coupling between optical devices and PCBs, which affects the use effect of the optical module.

[0030] The utility model proposes a coupling device for an optical device and a PCB, comprising a base plate 10, a three-axis slide 20, a clamping structure 30 and a mounting seat 40, wherein the three-axis slide 20 is mounted on the base plate 10, and an adapter plate assembly 50 is mounted on the three-axis slide 20, and the three-axis slide 20 can drive the adapter plate assembly 50 to move along the X direction, the Y direction and the Z direction; the clamping structure 30 comprises a surrounding block 31, a driving assembly 32 and two clamping pieces 33, the surrounding block 31 is mounted on the bottom of the adapter plate assembly 50, and each clamping piece 33 is slidably arranged at the bottom of the surrounding block 31, and the driving assembly 32 is mounted on the surrounding block 31, and the driving assembly 32 is used to drive the two clamping pieces 33 to slide relative to the surrounding block 31, so that the two clamping pieces 33 are close to or away from each other, so as to clamp or release the optical device 60 accordingly; the mounting seat 40 is mounted on the base plate 10, and the mounting seat 40 is correspondingly arranged below the clamping structure 30, and the top of the mounting seat 40 forms an operating table for placing the PCB 70.

[0031] See also Figure 1 , Figure 1 The left and right direction in is the X direction. Figure 1 The front-to-back direction is the Y direction. Figure 1 The up-down direction in is the Z direction. The enclosing block 31 is installed at the bottom of the adapter plate assembly 50, and the two clamping pieces 33 extend downward from the enclosing block 31 to the bottom of the enclosing block 31, so that the two clamping pieces 33 are correspondingly arranged above the mounting seat 40, and the three-axis slide 20 drives the adapter plate assembly 50 to move along the X direction, the Y direction and the Z direction to drive the clamping structure 30 to move along the X direction, the Y direction and the Z direction. When the driving assembly 32 drives the two clamping pieces 33 to approach each other to clamp the optical device 60, the three-axis slide 20 drives the clamping structure 30 to move along the X direction and the Y direction, so that the optical device 60 is aligned with the PCB 70 placed on the operating table, and then the three-axis slide 20 drives the clamping structure 30 to move along the Z direction, so that the optical device 60 gradually approaches the PCB 70 until coupling. Similarly, after the optical device 60 is coupled with the PCB 70, the driving assembly 32 drives the two clamping plates 33 to move away from each other to loosen the optical device 60, and then drives the clamping structure 30 to gradually move away from the PCB 70 along the Z direction through the three-axis slide 20, preparing for clamping and coupling the next optical device 60.

[0032] The coupling device of the optical device and the PCB proposed in the utility model clamps the optical device 60 by setting a clamping structure 30, places and fixes the PCB 70 by setting a mounting seat 40, and the clamping structure 30 is connected to the three-axis slide 20 through the adapter plate assembly 50. After the clamping structure 30 clamps the optical device 60, the operator manually operates the three-axis slide 20 to drive the clamping structure 30 to move along the X and Y directions to ensure that the optical device 60 and the PCB 70 are accurately aligned in the Z direction, that is, in the vertical direction. Then, the operator manually operates the three-axis slide 20 to drive the clamping structure 30 to move along the Z direction, so that the optical device 60 and the PCB 70 gradually approach each other until the coupling is completed, thereby realizing the precise coupling of the optical device 60 and the PCB 70. The clamping structure 30 clamps the optical device 60 by bringing the two clamping plates 33 close to each other, and can adapt to optical devices 60 of different sizes, and has good adaptability.

[0033] The coupling device of the optical device and the PCB of the utility model can realize the precise coupling of the optical device 60 and the PCB 70 through manual coupling operation, effectively improve the coupling accuracy under manual operation, ensure the coupling quality of the optical device 60 and the PCB 70, and the three-axis slide 20 supports manual operation, which is simple to operate and does not require multiple mold openings, which can save a lot of mold opening costs.

[0034] In one embodiment, the clamping structure 30 also includes two sliding plates 34, and a receiving cavity is formed in the enclosing block 31. The two sliding plates 34 are arranged at intervals along the X direction and can be slidably arranged in the receiving cavity. A clamping opening is formed at the bottom of the enclosing block 31, and two clamping pieces 33 are respectively connected to the bottom of the two sliding plates 34 and extend out of the receiving cavity through the clamping opening; the driving component 32 is used to drive the two sliding plates 34 to slide along the X direction in the receiving cavity, so as to respectively drive the two clamping pieces 33 to slide relative to the enclosing block 31, so that the two clamping pieces 33 are close to or away from each other.

[0035] See also Figure 2 , the two sliding plates 34 are arranged at intervals along the X direction, and the two sliding plates 34 can slide toward or away from each other under the drive of the driving assembly 32. When the driving assembly 32 drives the two sliding plates 34 to slide toward each other, the two clamping pieces 33 respectively connected to the lower part of the two sliding plates 34 approach each other to clamp the optical device 60; when the driving assembly 32 drives the two sliding plates 34 to slide away from each other, the two clamping pieces 33 move away from each other to release the optical device 60. The driving assembly 32 drives the two sliding plates 34 to move synchronously, so that the two clamping pieces 33 keep moving synchronously, and the two clamping pieces 33 have the same clamping force, which is helpful for the stable clamping of the optical device 60.

[0036] In one embodiment, the driving assembly 32 includes a pushing block 321 and a transmission module. The pushing block 321 is slidably disposed in the accommodating cavity. The two side surfaces of the pushing block 321 facing the two sliding plates 34 are inclined to form two inclined surfaces. The driving transmission module drives the pushing block 321 to slide between the two sliding plates 34 along the Y direction, so that the two sliding plates 34 are respectively abutted against the two sliding plates 34 through the two inclined surfaces, so that the two sliding plates 34 slide away from each other along the X direction. The transmission module can drive the pushing block 321 to slide out from between the two sliding plates 34 along the Y direction, so that the two sliding plates 34 slide close to each other along the X direction.

[0037] See also Figure 2 The two inclined surfaces on the pushing block 321 are respectively provided for the two sliding plates 34. When the pushing block 321 slides toward the two sliding plates 34 along the Y direction, each inclined surface gradually approaches the corresponding sliding plate 34 until it abuts against the sliding plate 34. As the pushing block 321 gradually slides between the two sliding plates 34 along the Y direction, each inclined surface abuts against and drives the corresponding sliding plate 34 to move along the X direction. The two inclined surfaces drive the two sliding plates 34 to gradually move away from each other, so that the two sliding plates 34 are squeezed apart by the pushing block 321, so that the two clamping pieces 33 under the two sliding plates 34 move away from each other. The structural setting is ingenious and the operation is convenient.

[0038] In one embodiment, the transmission module includes a transmission rod 323 and two elastic members 324. An avoidance groove 322 is provided at the top of the surrounding block 31. The top of the push block 321 extends upward into the avoidance groove 322. The transmission rod 323 is located in the avoidance groove 322 and is connected to the top of the push block 321. The transmission rod 323 is used to drive the push block 321 to slide between the two sliding plates 34 or slide out from between the two sliding plates 34 along the Y direction; the two elastic members 324 both extend along the X direction and are respectively connected between the two sliding plates 34 and the inner cavity walls of the accommodating cavity on the corresponding sides; the two elastic members 324 are used to drive the two sliding plates 34 to slide close to each other along the X direction when the transmission rod 323 drives the push block 321 to slide out from between the two sliding plates 34 along the Y direction.

[0039] See also Figure 2The transmission rod 323 is connected to the push block 321 and extends outward, so that the operator can manually control the movement of the push block 321 through the transmission rod 323, thereby manually clamping or releasing the optical device 60. Each sliding plate 34 is connected to the inner wall of the accommodating cavity through a corresponding elastic member 324. When the sliding plate 34 is squeezed by the push block 321 and moves along the X direction, the sliding plate 34 squeezes the elastic member 324 connected thereto; when the push block 321 slides out from between the two sliding plates 34, the sliding plate 34 moves in a direction away from the inner wall of the accommodating cavity under the action of the elastic member 324, so that the two sliding plates 34 move toward each other through the two elastic members 324, so that the two clamping plates 33 maintain the clamping force on the optical device 60.

[0040] In one embodiment, the surrounding block 31 is formed by splicing two limit blocks 312, and the two limit blocks 312 are connected by multiple screws. The limit blocks 312 are provided with loading and unloading holes 313 corresponding to the positions of the screws, and the joint of the two limit blocks 312 forms an avoidance groove 322.

[0041] It can be understood that the two ends of each screw rod are respectively inserted into the two limit blocks 312, and each screw rod is bolted to the limit blocks 312, so that the two limit blocks 312 are connected by multiple screw rods. The surrounding block 31 is formed by splicing two limit blocks 312 together, which is convenient for disassembly and assembly, and it is convenient to repair and replace the components in the surrounding block 31; the outer wall of the limit block 312 is provided with a loading and unloading hole 313 corresponding to the position of the screw rod, which is convenient for quick loading and unloading of the screw rod.

[0042] In one embodiment, two ends of each sliding plate 34 along the Y direction are respectively abutted against the inner cavity wall of the accommodating cavity on the corresponding side through two limiting pillars.

[0043] It should be noted that each limit column is connected to the inner wall of the accommodating cavity and can abut against the corresponding sliding plate 34. Each sliding plate 34 is respectively provided with two limit columns, and the two limit columns abut against the two ends of the sliding plate 34 along the Y direction respectively to limit the movement of the sliding plate 34 along the Y direction, so that the sliding plate 34 can only move along the X direction. The limit columns guide the sliding of the sliding plate 34 and can maintain the stable sliding of the sliding plate 34.

[0044] In one embodiment, the adapter plate assembly 50 includes a first adapter plate 51, a second adapter plate 52, a third adapter plate 53 and a rotating plate 54, the first adapter plate 51 is mounted on the three-axis slide 20, the second adapter plate 52 is mounted on the first adapter plate 51, the third adapter plate 53 extends along the X direction, one end of the third adapter plate 53 is mounted on the second adapter plate 52, and the rotating plate 54 is mounted on the bottom of the other end of the third adapter plate 53, and the enclosing block 31 is mounted on the bottom of the rotating plate 54 and can rotate around the Z direction together with the rotating plate 54.

[0045] It can be understood that the first adapter plate 51, the second adapter plate 52, the third adapter plate 53 and the rotating plate 54 form a multi-layer structure, the first adapter plate 51 and the second adapter plate 52 provide stable support for the third adapter plate 53, the third adapter plate 53 extends above the mounting seat 40, and the third adapter plate 53 provides support for the rotating plate 54, so that the three-axis slide 20 can drive the adapter plate to move along the X direction, the Y direction and the Z direction, and the adapter plate can drive the surrounding block 31 to rotate around the Z direction, so as to facilitate the adjustment of the direction of the optical device 60 when the clamping structure 30 clamps the optical device 60, so as to accurately couple the optical device 60 with the PCB 70.

[0046] In one embodiment, a mounting protrusion is formed on the top of the surrounding block 31 along the X direction, and a mounting groove matching the mounting protrusion is formed on the bottom of the rotating plate 54, and the mounting protrusion is slidably disposed in the mounting groove along the Y direction.

[0047] See also Figure 2 The top of the surrounding block 31 extends horizontally outward to form a mounting protrusion, and the surrounding block 31 can slide in the mounting groove along the Y direction through the mounting protrusion, which is convenient for the mounting and dismounting of the surrounding block 31 and the rotating plate 54. A fastener is penetrated at the bottom of the rotating plate 54. When the surrounding block 31 slides into the mounting groove, the fastener can pass through the rotating plate 54 and abut against the surrounding block 31, so that the surrounding block 31 and the rotating plate 54 remain fixed.

[0049] See also Figure 3 and Figure 4 The positioning block 35 is installed at the clamping opening of the surrounding block 31, and the two clamping pieces 33 extend downward from both sides of the positioning block 35. When the two clamping pieces 33 clamp the optical device 60, the optical device 60 can be engaged with the positioning groove 351 at the bottom of the positioning block 35, further maintaining the stability of the optical device 60. The bottoms of the two clamping pieces 33 are inclined in a direction close to each other, so that the two clamping pieces 33 have a stable and uniform clamping force, ensuring the stable clamping of the optical device 60.

[0050] In one embodiment, the mounting seat 40 includes a base, a connecting plate and a swing slide. The base is fixed on the bottom plate 10. A U-shaped groove is provided on the base. The connecting plate can be plugged into the U-shaped groove. The swing slide is installed on the connecting plate and can slide along the X and Y directions.
