Description

Technical Field

[0001] The utility model relates to the field of optical modules, and in particular to an optical fiber array coupling platform suitable for multiple models. Background Art

[0002] In traditional optical modules, the coupling of optical fiber arrays is mostly done manually by staff. The following problems exist during batch coupling:

[0003] 1) Since there is no corresponding reference in the coupling process, the coupling process takes a long time;

[0004] 2) The tooling used for coupling uses a rubber nozzle to absorb the optical fiber array. The suction force is unstable and there is no limit when the optical fiber array is absorbed, resulting in an uncertain angle of the optical fiber array each time it is loaded and unloaded. The staff often have to adjust the angle manually, which is time-consuming. In addition, due to the low suction force of the rubber nozzle, the coupling power of the optical fiber array often changes. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a fiber array coupling station applicable to multiple models, so as to overcome the deficiencies in the above-mentioned prior art.

[0006] The utility model solves the above-mentioned technical problem with the following technical solution: a fiber array coupling platform applicable to multiple models, comprising: a base plate, and a Z-axis lifting platform and an XY displacement platform fixed at corresponding positions on the base plate, a multi-dimensional fine-tuning frame fixed on the Z-axis lifting platform, an automatic clamp fixed on the multi-dimensional fine-tuning frame, an angular displacement platform fixed on the XY displacement platform, an R-axis rotating platform fixed on the angular displacement platform, a product base fixed on the R-axis rotating platform in a detachable manner; a camera is arranged on the X, Y, and Z-axis directions of the product on the corresponding product base, and each camera is fixed to the base plate via a fine-tuning frame.

[0007] The beneficial effect of the utility model is as follows: since a camera is fixedly arranged in the X, Y and Z axis directions of the product on the corresponding product base, and each camera display interface displays a reference line, the product is first made parallel to the reference lines of the cameras in the X, Y and Z axis directions through the cooperation of the XY translation table, the angular translation table and the R-axis rotation table, and then the optical fiber array clamped by the automatic clamp is coupled with the product through the cooperation of the Z-axis lifting table and the multi-dimensional fine-tuning frame, thereby effectively shortening the coupling time. In addition, since the product base on the R-axis rotation table can be disassembled, it is only necessary to replace the product base for different models of products, so that the coupling table can be applied to the coupling of a variety of different models of products.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the automatic clamp comprises: a power mechanism, a clamping plate and a clamping claw, wherein the clamping plate and the clamping claw are respectively fixed on the power mechanism and move closer to and farther from each other under the action of the power mechanism.

[0010] A further beneficial effect of the above method is that the optical fiber array can be clamped by the clamp, and the clamping is more stable and consistent than that of a rubber nozzle.

[0011] Furthermore, the length of the clamping jaw is shorter than that of the clamping plate, a baffle is provided at the clamping end of the clamping jaw, the sum of the lengths of the clamping jaw and the baffle is longer than the length of the clamping plate, and a side of the baffle close to the clamping plate has an avoidance hole at the junction with the clamping jaw.

[0012] The above further beneficial effects are: the baffle can limit the optical fiber array to ensure that the clamping angle is fixed, and the staff does not need to manually adjust the angle of the clamped optical fiber array, saving time, and the avoidance hole can prevent the edge of the optical fiber array from collapsing, thereby ensuring the yield of the final product.

[0013] Furthermore, the power mechanism adopts parallel opening and closing air claws.

[0014] The above further beneficial effects are: easy operation and effective control of the clamping force.

[0015] Furthermore, the multi-dimensional fine-tuning frame adopts a six-dimensional adjustment frame.

[0016] Furthermore, the bottom plate adopts an optical platform, and the Z-axis lifting platform, the XY translation platform and the fine-tuning frame are respectively fixed to the optical platform via screws.

[0017] The above further beneficial effects are: good flatness, and convenient assembly and disassembly of the Z-axis lifting platform, the XY translation platform and the fine-tuning frame as well as position adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] Example 1

[0024] like Figure 1 As shown, a fiber array coupling station suitable for multiple models includes:

[0025] Base plate 1, Z-axis lifting platform 2 and XY translation platform 3, Z-axis lifting platform 2 and XY translation platform 3 are respectively fixed at corresponding positions on base plate 1, a multi-dimensional fine-tuning frame 4 is fixed on Z-axis lifting platform 2, automatic clamp 5 is fixed on multi-dimensional fine-tuning frame 4, multi-dimensional fine-tuning frame 4 adopts existing mature technology, automatic clamp 5 is used to clamp optical fiber array; Z-axis lifting platform 2 can adjust the height of multi-dimensional fine-tuning frame 4, automatic clamp 5 and optical fiber array clamped by automatic clamp 5 in Z-axis direction to adapt to products of different heights, and multi-dimensional fine-tuning frame 4 can adjust automatic clamp 5 and optical fiber array clamped by automatic clamp 5 in multiple dimensions; through the cooperation of Z-axis lifting platform 2 and multi-dimensional fine-tuning frame 4, on the one hand, the position and orientation of automatic clamp 5 can be adjusted to clamp optical fiber array, on the other hand, after clamping optical fiber array, the position and orientation of optical fiber array can be adjusted according to coupling requirements;

[0026] An angular displacement table 6 is fixed on the XY displacement table 3, an R-axis rotation table 7 is fixed on the angular displacement table 6, a product base is detachably fixed on the R-axis rotation table 7, and the product base can be replaced according to different types of products. The product base is used to fix the product, wherein the product can be a PCB board and other optical devices installed on the PCB board, and the optical fiber array coupling is coupled with the optical device. The XY displacement table 3 can adjust the position of the angular displacement table 6, the R-axis rotation table 7, the product base and the product on the product base in the X and Y axis directions, the angular displacement table 6 can adjust the angle of the R-axis rotation table 7, the product base and the product on the product base, and the R-axis rotation table 7 can adjust the orientation of the product base and the product on the product base on the R axis; through the cooperation of the XY displacement table 3, the angular displacement table 6 and the R-axis rotation table 7, the product on the product base can be adjusted in the X-axis, Y-axis, angle and R-axis directions according to the coupling requirements;

[0027] A camera 9 is arranged on the corresponding product base in the X, Y and Z axis directions of the product, and each camera 9 is fixed to the base plate 1 via a fine-tuning frame 8. Since the display interface of each camera 9 displays a reference line, the product is first made parallel to the reference line of the camera 9 in the X, Y and Z axis directions through the cooperation of the XY displacement table 3, the angular displacement table 6 and the R-axis rotation table 7, so that it can be judged that the product is in a balanced state. Then, the optical fiber array clamped by the automatic clamp 5 can be coupled with the product through the cooperation of the Z-axis lifting platform 2 and the multi-dimensional fine-tuning frame 4, which can effectively shorten the coupling time.

[0028] Example 2

[0029] like Figure 1 , Figure 2 As shown, this embodiment is a further improvement on the basis of embodiment 1, and the details are as follows:

[0030] The automatic clamp 5 includes: a power mechanism 510, a clamping plate 520 and a clamping claw 530. The clamping plate 520 and the clamping claw 530 are respectively fixed on the power mechanism 510. The clamping plate 520 and the clamping claw 530 can approach and move away from each other under the action of the power mechanism 510, so that the clamping plate 520 and the clamping claw 530 can complete the clamping and releasing actions of the optical fiber array, and the clamping is stable and consistent.

The sum of the lengths of the clamping jaw 530 and the baffle 540 is longer than the length of the clamping plate 520.

The side of the baffle 540 close to the clamping plate 520 has an avoidance hole 550 at the junction with the clamping jaw 530. The avoidance hole 550 can prevent the edges and corners of the optical fiber array from collapsing, thereby ensuring the yield of the final product.

[0032] The power mechanism 510 preferably adopts a parallel opening and closing air jaw, and the splint 520 and the clamping jaw 530 are respectively installed on the two fingers of the parallel opening and closing air jaw. The two fingers are controlled to approach and move away from each other by the parallel opening and closing air jaw, so as to control the splint 520 and the clamping jaw 530 to approach and move away from each other. Of course, in actual application, the use of power mechanisms 510 with other structures is not excluded, such as using electric cylinders.
