[0002] In the current market, there is a growing demand for smaller overall optical modules to improve user experience and meet miniaturization requirements. Typically, before assembling an optical module, it needs to be tested to obtain accurate actual optical performance. This allows for optimization of the optical module design to achieve a higher quality result.

[0003] Existing debugging instruments include lens clamps, fine-tuning platforms, and other related structures. Optical modules generally consist of multiple lenses, each held by a different lens clamp. However, due to the large size of the lens clamps, they can only be used for debugging optical modules with larger lenses and longer optical paths, and cannot be used for debugging small optical modules with smaller lenses and shorter lens spacing. Utility Model Content

[0004] The purpose of this invention is to provide a laser testing fixture platform and a laser testing system, which aims to solve the technical problem that the existing lens clamps are large in size and can only be used for debugging optical modules with large lenses and long optical paths, and cannot be used for debugging small optical modules with small lenses and short lens spacing.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] In some possible implementations, the projected profile of the mounting portion is larger than the projected profile of the straight portion on a plane perpendicular to the adjusting rod.

[0010] In some possible implementations, the lens mounting plate has a first adapter hole that mates with the adjustment rod, and the straight fitting has a second adapter hole that mates with the adjustment rod, wherein the adaptation length of the first adapter hole is less than the adaptation length of the second adapter hole.

[0011] In some possible implementations, multiple adjustment rods are evenly spaced around the light outlet, and the projections of multiple lens mounting holes overlap on a plane perpendicular to the adjustment rods.

[0012] In some possible implementations, each of the two adjusting rods in each group is provided with a lens mounting plate, and a plurality of lens mounting plates are spaced apart along the length of the adjusting rods.

[0013] In some possible implementations, at least one set of two adjustment rods are provided with two or more lens mounting plates, and the two or more lens mounting plates are spaced apart in the length direction of the adjustment rods.

[0014] In some possible implementations, the laser mounting base is located on the side of the first side plate away from the second side plate, and the first side plate has a light-transmitting opening for the laser to emit light.

[0015] Secondly, this utility model also provides a laser testing system, comprising: a laser testing fixture platform as described in any of the above implementations; a laser, mounted on the laser mounting base; and a plurality of lenses, each mounted in a different lens mounting hole.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0030] Please also refer to Figures 1 to 7 The following is a detailed description of the laser testing fixture platform and laser testing system provided in the embodiments of this utility model.

[0031] Please see Figures 1 to 4 This utility model provides a laser testing fixture platform 1, including: a testing base 10, including a base plate 11, and a first side plate 12 and a second side plate 13 connected to the base plate 11. The first side plate 12 has a laser mounting seat 121, and the second side plate 13 has a light outlet 131; a plurality of linear adjustment components 20, each linear adjustment component 20 including: an adjustment rod 21 disposed between the first side plate 12 and the second side plate 13; and a plurality of lens mounting plates 30, each lens mounting plate 30 passing through two adjustment rods 21, each lens mounting plate 30 having a lens mounting hole 31 located within the coverage area of ​​the light outlet 131, and each lens mounting plate 30 being slidably disposed on two adjustment rods 21.

[0032] Specifically, the laser mounting base 121 is used to mount the laser; the light outlet 131 is used for light emission; the adjusting rod 21 is set perpendicular to the first side plate 12 and the second side plate 13, the first side plate 12 has a first fixing hole 123, the second side plate 13 has a second fixing hole 132, and the adjusting rod 21 is fixed in the first fixing hole 123 and the second fixing hole 132; the lens mounting hole 31 is used to mount the lens, for example, the lens can be set in the lens mounting hole 31 by applying glue.

[0033] The lens mounting plate 30 is mounted on two adjusting rods 21 and can slide relative to the adjusting rods 21 to adjust the distance between adjacent lenses and the distance between the lens and the laser, thereby adjusting the entire optical module. For example, distance scales can be set on the adjusting rods 21 to more precisely adjust the moving distance of the lens mounting plate 30. Alternatively, when the lens mounting plate 30 moves to the target position, positioning clamps or retaining rings with openings can be provided on one or both sides of the lens mounting plate 30 to limit its movement on the adjusting rods 21.

[0034] It should be noted that, according to the number of lenses in the optical module, a target number of lens mounting plates 30 can be set on the adjustment rod 21. Two adjustment rods 21 are set as a group, and the two adjustment rods 21 in each group can be set with one or more lens mounting plates 30. There is no restriction on this.

[0035] Compared with the prior art, the laser testing fixture platform 1 provided in this embodiment of the present invention has at least the following technical effects: The laser testing fixture platform 1 includes a testing base 10, a linear adjustment component 20, and a lens mounting plate 30. The lens in the optical module is placed in the lens mounting hole 31 of the lens mounting plate 30 without increasing the space occupied. It does not require a large lens clamp and can be used for smaller lenses. Furthermore, the two ends of the lens mounting plate 30 are slidably mounted on two adjustment rods 21. By setting multiple sets of adjustment rods 21 and lens mounting plates 30, the distance between adjacent lenses and the distance between the lens and the laser can be flexibly adjusted to achieve the function of adjusting the entire optical module. It can be used for optical modules with short lens spacing. The overall structure is simpler and the operation is more flexible.

[0036] The specific structures of the test base 10, the linear adjustment assembly 20, and the lens mounting plate 30 are described in detail below.

[0037] Please see Figures 1 to 3 , Figures 5 to 7 In some embodiments, each linear adjustment assembly 20 further includes a linear sleeve 22 fitted onto the adjustment rod 21, the linear sleeve 22 being connected to the lens mounting plate 30. In this embodiment, the linear sleeve 22 can be slidably disposed relative to the adjustment rod 21, and the linear sleeve 22 and the lens mounting plate 30 are synchronously slidably disposed relative to the adjustment rod 21. The linear sleeve 22 can increase the contact area with the adjustment rod 21, further ensuring the stability of the lens mounting plate 30 during the sliding process, and further ensuring that both sides of the lens mounting plate 30 can slide synchronously, avoiding the lens mounting plate 30 from tilting during the sliding process, thereby ensuring the perpendicularity of the lens to the optical axis.

[0038] like Figures 5 to 7As shown, in one specific embodiment, the straight section kit 22 includes a straight section 221 and a mounting section 222 connected to each other. Both the straight section 221 and the mounting section 222 are sleeved on the adjusting rod 21, and the mounting section 222 is connected to the lens mounting plate 30. Specifically, the straight section 221 can be a sleeve-shaped structure, and the mounting section 222 can be a sleeve-shaped structure, a plate-shaped structure, etc. The mounting section 222 has a third fixing hole 2221, and the lens mounting plate 30 has a fourth fixing hole 33. The mounting section 222 is connected to the lens mounting plate 30 by bolts locked in the third fixing hole 2221 and the fourth fixing hole 33, which facilitates the disassembly and replacement of the lens mounting plate 30.

[0039] In addition, the mounting part 222 and the lens mounting plate 30 can also be fixed together by snap-fitting, binding or other methods.

[0040] like Figures 5 to 7 As shown, in one specific embodiment, the projected profile of the mounting portion 222 is larger than the projected profile of the straight portion 221 on a plane perpendicular to the adjusting rod 21. For example, the straight portion 221 is a sleeve-shaped structure, and the mounting portion 222 is a plate-shaped structure or a sleeve-shaped structure covering the straight portion 221. This arrangement results in a larger mounting area between the mounting portion 222 and the lens mounting plate 30, and reduces the wall thickness of the straight portion 221.

[0041] like Figures 5 to 7 As shown, in one specific embodiment, the lens mounting plate 30 has a first adapter hole 32 that mates with the adjusting rod 21, and the linear assembly 22 has a second adapter hole 223 that mates with the adjusting rod 21. The adapter length of the first adapter hole 32 is less than the adapter length of the second adapter hole 223. The linear portion 221 and the mounting portion 222 share a common opening to form the second adapter hole 223. This arrangement increases the contact area between the linear assembly 22 and the adjusting rod 21, thus ensuring that the lens mounting plate 30 does not skew during sliding and maintaining the perpendicularity of the lens to the optical axis.

[0042] Please see Figures 1 to 4 In some embodiments, multiple adjusting rods 21 are evenly spaced around the light outlet 131, and the projections of multiple lens mounting holes 31 coincide on a plane perpendicular to the adjusting rods 21. In this embodiment, the evenly spaced multiple adjusting rods 21 ensure that the lens mounting holes 31 of the multiple lens mounting plates 30 are on the same straight line, that is, the projections of the multiple lens mounting holes 31 coincide on a plane perpendicular to the adjusting rods 21, thus ensuring the coaxiality of the multiple lenses of the optical module.

[0043] Furthermore, in other embodiments, if the multiple lenses of the optical module are not required to be coaxially arranged, the lens mounting plate 30 with different lens mounting holes 31 can be replaced to meet diverse needs.

[0044] It should be noted that different lens mounting plates 30 can be set on two different adjusting rods 21, or they can be set on the same two adjusting rods 21.

[0045] For example, multiple lens mounting plates 30 are each disposed on two different adjusting rods 21, that is, each pair of adjusting rods 21 is provided with one lens mounting plate 30, and the multiple lens mounting plates 30 are spaced apart along the length of the adjusting rods 21. This arrangement allows for a wider range of adjustment of the distance between adjacent lens mounting plates 30.

[0046] For example, a portion of the lens mounting plates 30 are disposed on the same two adjusting rods 21, that is, at least one set of two adjusting rods 21 are provided with two or more lens mounting plates 30, and this portion of the lens mounting plates 30 are spaced apart in the length direction of the adjusting rods 21. Relatively speaking, this method has a smaller range of adjustment for the distance between adjacent lens mounting plates 30, but the number of lens mounting plates 30 is relatively large.

[0047] Please see Figures 1 to 3 In some embodiments, the laser mounting base 121 is located on the side of the first side plate 12 away from the second side plate 13, and the first side plate 12 has a light-transmitting opening 122 for the laser to emit light. In this embodiment, the laser mounting base 121 does not need to occupy the space between the first side plate 12 and the second side plate 13, allowing the lens mounting plate 30 to have a larger adjustment distance. The laser mounting base 121 can be located at the light-transmitting opening 122 or at a position adjacent to the light-transmitting opening 122, as long as the laser can emit light through the light-transmitting opening 122 after installation.

[0048] In addition, in other embodiments, the thickness of the first side plate 12 may be increased to embed the laser within the thickness range of the first side plate 12, and there is no limitation thereto.

[0049] Based on the same technical concept, this utility model embodiment also provides a laser testing system, including: a laser testing fixture platform 1 as described in any of the above embodiments; a laser, installed in the laser mounting base 121; and a plurality of lenses, respectively installed in different lens mounting holes 31.

[0050] Specifically, the laser is mounted on the laser mounting base 121, and the light emitted by the laser can be transmitted to several lenses through the light transmission port 122. By adjusting the positions of different laser mounting plates on different adjustment rods 21, a preset lens spacing is formed, and the optical module composed of several lenses is tested.

[0051] The laser can be installed on the laser mounting base 121 by means of threaded connection, snap-fit, etc. The lens can be installed in the lens mounting hole 31 by applying glue, or the lens can be placed between the step and the cap by setting a step outside the lens mounting hole 31 and adding a cap. The glue application method is simpler and more convenient and does not increase the thickness of the lens mounting plate 30.

[0052] The laser testing system provided in this embodiment includes the laser testing fixture platform 1 described in any of the above embodiments. The two have the same technical effect, and will not be described again here.

[0053] It is understood that the parts in the above embodiments can be freely combined or deleted to form different combined embodiments. The specific contents of each combined embodiment will not be repeated here. After this description, it can be considered that the present utility model specification has recorded each combined embodiment and can support different combined embodiments.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
