[0031] See also Figures 1 to 7 , an embodiment of the present application provides an optical module adjustment fixture, the optical module 900 includes a module bracket 910 and a receiving element 920 arranged on the module bracket 910, the optical module adjustment fixture includes a support 100, a lifting mechanism 200 arranged on the support 100, a rotating mechanism 300 rotatably connected to the lifting mechanism 200, a grasping mechanism 400 for grasping the receiving element 920, a testing mechanism 500 for testing the receiving element 920, and a clamping mechanism 600 for clamping the module bracket 910, the lifting mechanism 200 is used to drive the rotating mechanism 300 to rise and fall along a first direction a, the grasping mechanism 400 and the module bracket 910 are spaced apart along the first direction a, the grasping mechanism 400 is connected to the output end of the rotating mechanism 300, the rotating mechanism 300 is used to drive the grasping mechanism 400 to rotate around the rotation axis according to the testing mechanism 500 to adjust the placement orientation of the receiving element 920 on the module bracket 910, and the rotation axis extends along the first direction a.

[0032] It should be noted that the receiving element 920 of the embodiment of the present application is an important element of the optical module. The optical module 900 generally includes a module bracket 910 and structures such as a transmitting element and a receiving element 920 installed on the optical module bracket 440.

[0033] The optical module adjustment fixture provided in this application clamps the module bracket 910 on the clamping mechanism 600, and the gripping mechanism 400 is used to grip the receiving element 920. At this time, the rotating mechanism 300 can drive the gripping mechanism 400 to rotate to adjust the direction of the receiving element 920, and determine the placement of the receiving element 920 on the module bracket 910 based on the test results of the testing mechanism 500, so as to facilitate the subsequent direct installation of the receiving element 920 on the module bracket 910. The entire process is greatly automated through the automatic coordination and operation of the gripping mechanism 400, the lifting mechanism 200, the rotating mechanism 300, and the testing mechanism 500, thereby greatly improving the adjustment efficiency of the optical module 900. After the adjustment is completed, the staff can apply glue to bond the receiving element 920 to the module bracket 910.

[0034] In some embodiments, the optical module adjustment fixture also includes a linear drive mechanism 700, and the testing mechanism 500 is slidably set on the linear drive mechanism 700. The linear drive mechanism 700 is used to drive the testing mechanism 500 to move along the second direction b so that the testing mechanism 500 is close to or away from the receiving element 920. The first direction a and the second direction b are perpendicular to each other.

[0035] By providing the linear drive mechanism 700, the distance between the test mechanism 500 and the receiving element 920 can be adjusted according to actual conditions, thereby making the test effect more accurate. Specifically, the linear drive mechanism 700 of the present application can be a linear motor.

[0036] Specifically, the testing mechanism 500 includes a mounting bracket and a reflective structure mounted thereon. The reflective surface of the reflective structure faces the receiving element 920. Specifically, during testing, the emitting element on the module bracket 910 emits light toward the reflective structure. The emitting element may be a laser, for example. The reflective structure then reflects the light emitted by the emitting element toward the receiving element 920, where it is received by the receiving element 920, thereby testing the receiving element 920. Specifically, the reflective structure is a ceramic plate.

[0037] In some embodiments, the gripping mechanism 400 includes a connecting base 410 and a pin 420 elastically connected to the connecting base 410 on the side facing the receiving element 920, the pin 420 extends along the first direction a, and the receiving element 920 is provided with a plug-in hole 921 adapted for the pin 420, and the pin 420 is plugged into the plug-in hole 921 to grip the receiving element 920.

[0038] Since the ejector pin 420 is elastically connected to the connecting base 410, when the ejector pin 420 is connected to the receiving element 920, the vibration generated between the receiving element 920 and the ejector pin 420 when the ejector pin 420 and the receiving element 920 contact each other can be buffered, thereby avoiding rigid contact between the ejector pin 420 and the receiving element 920 and preventing the receiving element 920 from being damaged.

[0039] Specifically, a mounting hole 4111 is provided on the side of the connecting seat 410 facing the receiving element 920, the axis of the mounting hole 4111 extends along the first direction a, the ejector pin 420 is movably inserted into the mounting hole 4111, and an elastic member 430 is provided on the bottom wall of the mounting hole 4111, and the end of the ejector pin 420 facing away from the receiving element 920 abuts against the elastic member 430.

[0040] In the embodiment of the present application, the ends of the elastic member 430 elastically abut the bottom wall of the connecting hole 622 and the ejector pin 420, respectively. The provision of the elastic member 430 effectively cushions the vibrations generated between the receiving element 920 and the ejector pin 420 when the ejector pin 420 and the receiving element 920 come into contact, preventing damage to the receiving element 920 due to excessive impact force. Furthermore, the elastic member 430 can be adapted to different receiving elements 920 to ensure sufficient cushioning. Optionally, the elastic member 430 in the embodiment of the present application is a spring. Of course, in other possible embodiments, the elastic member 430 can also be a compression spring or rubber, etc. The specific structure of the elastic member 430 is not limited to this invention.

[0041] Furthermore, the ejector pin 420 includes a main body portion 421 extending along the first direction a and a needle head 422 connected to one end of the main body portion 421 facing the receiving element 920. The main body portion 421 extends into the mounting hole 4111. The main body portion 421 is connected to a bracket 440 at one end facing away from the receiving element 920. The bracket 440 is provided with a recessed portion 441 for accommodating the elastic member 430 on the side facing the elastic member 430.

[0042] Specifically, the main body 421 is a rod-shaped structure with sockets at both ends. The needle 422 and the bracket 440 are both provided with plug-in portions. The plug-in portions of the needle 422 and the bracket 440 are respectively plugged into the two sockets at both ends, thereby achieving a stable connection between the needle 422 and the bracket 440 and the main body 421. The recessed portion 441 on the side of the bracket 440 facing the elastic member 430 can accommodate the elastic member 430. The elastic member 430 extends into the recessed portion 441, thereby limiting the elastic member 430 and making the state of the elastic member 430 more stable.

[0043] Specifically, the connecting seat 410 is a cylindrical structure having a cavity 412 and an opening on one side. The opening of the connecting seat 410 is fixedly connected to the rotating mechanism 300 so that it can rotate with the rotating mechanism 300. A boss 411 is provided on the bottom wall of the cavity 412 away from the receiving element 920. The boss 411 is provided at the center position of the bottom wall. The mounting hole 4111 is provided on the boss 411 and the mounting hole 4111 passes through the boss 411. A baffle 450 is provided on the upper cover of the boss 411. The baffle 450 is fixedly connected to the edge of the boss 411. The boss 411 can resist the elastic member 430, thereby preventing the elastic member 430 from detaching from the mounting hole 4111.

[0044] In some embodiments, two ejector pins 420 are provided, and two corresponding insertion holes 921 are provided on the receiving element 920. The two insertion holes 921 are located at opposite ends of the top surface of the receiving element 920. This allows the ejector pins 420 to exert a more balanced force on the receiving element 920, making the gripping mechanism 400 more stable in gripping the receiving element 920, and preventing the receiving element 920 from shifting to one side during movement. Of course, in other possible embodiments, three, four, five, six, or more ejector pins 420 may be provided, and this application does not impose a single limitation on the number of ejector pins 420.

[0045] In some embodiments, the optical module adjustment fixture also includes a moving mechanism 800, which includes a base 810, a first moving platform 820 and a second moving platform 830. The base 810 is set on the support 100, the first moving platform 820 is set on the base 810, the second moving platform 830 is slidably set on the first moving platform 820, and the lifting mechanism 200 is slidably set on the second moving platform 830. The first moving platform 820 is used to drive the second moving platform 830 to move along the third direction c, and the second moving platform 830 is used to drive the lifting mechanism 200 to move along the second direction b. The second direction b and the third direction c are perpendicular to the first direction a.

[0046] Specifically, in the embodiment of the present application, the first direction a is perpendicular to the horizontal plane, the second direction b and the third direction c are parallel to the horizontal plane, and the second direction b and the third direction c are perpendicular to each other. By providing a movable structure, the lifting mechanism 200 can move along the second direction b and the third direction c, and the gripping mechanism 400 can move synchronously with the lifting mechanism 200. As a result, the gripping mechanism 400 can not only rotate, but also move in various directions on the horizontal plane and be lifted and lowered in the vertical direction, giving the gripping mechanism 400 a higher degree of freedom.

[0047] Specifically, the lifting mechanism 200 may include a handle 210 and a slide 220 . The slide 220 may be moved up and down by rotating the handle 210 . The rotating mechanism 300 is mounted on the slide 220 via a connecting plate, so the rotating mechanism 300 may move up and down with the slide 220 .

[0048] In some embodiments, the clamping mechanism 600 includes a base plate 610, a fixed seat 620 fixed on the base plate 610, a pressure block 630 slidably set on the base plate 610, an elastic connecting member 640 set between the fixed seat 620 and the pressure block 630, and a stop wall 615 set on the base plate 610. A limiting groove 611 for placing the part to be clamped is set on the base plate 610. The limiting groove 611 is used to limit the part to be clamped. The pressure block 630 is set between the fixed seat 620 and the part to be clamped. One end of the elastic connecting member 640 is fixed to the fixed seat 620, and the other end of the elastic connecting member 640 is elastically connected to the pressure block 630 so that the pressure block 630 elastically presses against the part to be clamped. The stop wall 615 is set on the side of the part to be clamped away from the pressure block 630, so as to clamp the part to be clamped together with the pressure block 630 along the first direction a.

[0049] The limiting groove 611 can limit the part to be clamped, and by arranging the pressure block 630 between the fixed seat 620 and the part to be clamped, the pressure block 630 elastically presses against the part to be clamped, and the pressure block 630 can extend toward the limiting groove 611 or retract away from the limiting groove 611, so that for parts to be clamped of different sizes, the end of the pressure block 630 facing the part to be clamped can always be in close contact with and press against the clamping part, so that adaptive adjustment can be made according to parts to be clamped of different models and specifications, solving the technical problem of low applicability of existing clamping tooling, having better versatility, and improving the applicability of the clamping structure.

[0050] In some embodiments, a fixing hole 623 is defined on the side of the fixing base 620 facing the part to be clamped. The end of the elastic connector 640 facing away from the pressure block 630 is inserted through the fixing hole 623 and fixed to the fixing hole 623. This ensures that the elastic connector 640 is firmly fixed and prevents it from detaching when the pressure block 630 acts on the part to be clamped. The simple structure of the elastic connector 640 not only facilitates pulling the pressure block 630 apart to place the part to be clamped, but also allows for clamping and positioning parts of different models and specifications.

[0051] Specifically, the elastic connector 640 is a spring-loaded ejector pin. The spring-loaded ejector pin may include a needle tube, a needle shaft, and a spring. The needle tube has a cavity 412 therein. The needle shaft is disposed within the cavity 412 with one end extending out of the needle tube. The needle shaft is movable along the axial direction of the needle tube. One end of the spring abuts against the head of the needle shaft, and the other end abuts against the bottom wall of the needle tube. The distal end of the needle shaft is connected to the pressing block 630, thereby enabling the pressing block 630 to be retractable.

[0052] Furthermore, a guide structure can be provided in the needle tube, and the main body 421 of the needle shaft cooperates with the first end and the guide structure in the needle tube. The guide structure can guide the needle shaft when the needle shaft moves along the axial direction of the needle tube, thereby reducing the possibility of the needle shaft deflecting, thereby reducing the possibility of the pressure block 630 deflecting, and ensuring the straightness of the movement of the pressure block 630.

[0053] In some embodiments, two elastic connectors 640 are provided, and the two elastic connectors 640 are respectively connected to the two ends of the pressing block 630. The extension directions of the two elastic connectors 640 are parallel to each other, and the two elastic connectors 640 are symmetrical to each other. Therefore, the force applied by the elastic connectors 640 to the pressing block 630 can be more balanced, so that the pressing block 630 will not deviate to one side during movement, thereby ensuring the straightness of the movement of the pressing block 630. Of course, in other possible embodiments, three, four, five, six, or more elastic connectors 640 can be provided, and this application does not impose a single limitation on the number of elastic connectors 640.

[0054] In addition, the position at which the elastic connector 640 is connected to the pressing block 630 can also be adjusted according to actual needs. For example, when the number of elastic connectors 640 is set to three, the three connection points formed by the three elastic connectors 640 and the pressing block 630 are connected end to end to form an equilateral triangle, thereby making the force exerted by the elastic connector 640 on the pressing block 630 more balanced.

[0055] In the embodiment of the present application, the shape of the retaining groove 611 is adapted to the shape of the part to be clamped. It is understood that since the part to be clamped may be a special-shaped part, that is, the part to be clamped may have an irregular shape, the shape of the retaining groove 611 can also be set to an irregular shape accordingly. This not only further improves the retaining effect of the part to be clamped, but also makes it easier for the operator to place the part to be clamped in the retaining groove 611 without interference.

[0056] In some embodiments, a placement groove 612 is further provided on the top surface of the base plate 610, and the fixing seat 620 and the pressure block 630 are arranged in the placement groove 612. The placement groove 612 is connected to the limiting groove 611, and the height of the bottom wall of the placement groove 612 is less than the height of the bottom wall of the limiting groove 611.

[0057] It can be understood that the placement groove 612 and the limiting groove 611 are both opened on the top surface of the base plate 610, and the placement groove 612 is connected to the limiting groove 611. The height of the bottom wall of the placement groove 612 is less than the height of the bottom wall of the limiting groove 611. The height of the installation position of the pressure block 630 is less than the height of the installation position of the part to be clamped. Therefore, when the pressure block 630 presses against the part to be clamped, the part to be clamped can contact the center position of the pressure block 630, so that the pressure block 630 can better apply force to the part to be clamped, further improving the clamping effect.

[0058] Furthermore, the base plate 610 also includes a retaining wall 613 connecting the bottom wall of the placement groove 612 and the bottom wall of the limiting groove 611. The retaining wall 613 faces the surface of the pressing block 630 and is perpendicular to the moving direction of the pressing block 630. The retaining wall 613 is used to resist the pressing block 630 to limit the moving stroke of the pressing block 630.

[0059] Since the height of the bottom wall of the placement groove 612 is less than the height of the bottom wall of the limiting groove 611, a retaining wall 613 is formed between the bottom wall of the placement groove 612 and the bottom wall of the limiting groove 611. The retaining wall 613 is located in the moving stroke of the pressing block 630, and when the part to be clamped is placed in the limiting groove 611, the side of the part to be clamped toward the pressing block 630 will extend beyond the retaining wall 613, so the pressing block 630 will abut against the part to be clamped instead of abutting against the retaining wall 613. The function of the retaining wall 613 is to prevent the pressing block 630 from extending excessively and causing damage to the part to be clamped.

[0060] In some embodiments, the fixing seat 620 is detachably connected to the base plate 610 , and the position of the fixing seat 620 is adjustable along the direction of the pressing block 630 pointing to the object to be clamped.

[0061] The fixing base 620 is detachably connected to the base plate 610, making it easy to replace the fixing base 620. In addition, since the position of the fixing base 620 is adjustable along the direction of the pressure block 630 pointing to the part to be clamped, the position of the fixing base 620 can be adjusted according to actual needs. For example, when the lateral dimension of the part to be clamped placed in the limit groove 611 is small, the fixing base 620 can be installed closer to the limit groove 611, so that the clamping effect is better; and when the lateral dimension of the part to be clamped placed in the limit groove 611 is large, the fixing base 620 can be installed farther away from the limit groove 611, so that the pressure block 630 has sufficient space to retract. That is, the installation position of the fixing base 620 can be adaptively adjusted according to different models and specifications of the parts to be clamped, further improving the applicability of the clamping tooling.

[0062] Specifically, a waist-shaped hole 621 can be opened on the fixing seat 620, and a positioning hole 614 corresponding to the waist-shaped hole 621 can be opened on the bottom plate 610. Fasteners are respectively passed through the waist-shaped hole 621 and the positioning hole 614 to adjust the installation position of the fixing seat 620.

[0063] In some embodiments, a connection hole 622 is opened on the top surface of the fixing seat 620, and the optical module adjustment fixture also includes a fastener (not shown in the figure), which is movably passed through the connection hole 622 and is used to press against the side wall of the elastic connector 640 to fix the elastic connector 640.

[0064] The working principle of the clamping mechanism 600 of the present application is as follows: manually pull the pressure block 630 toward the fixing seat 620, and then place the part to be clamped horizontally on the base plate 610, so that the part to be clamped is accommodated in the limiting groove 611, and the inner wall of the limiting groove 611 abuts against the side of the part to be clamped; since the pressure block 630 is telescopically connected to the fixing seat 620, for a part to be clamped with a smaller horizontal dimension, the pressure block 630 can extend toward the limiting groove 611, so that the pressure block 630 can be closely attached to the part to be clamped; for a part to be clamped with a larger horizontal dimension, the pressure block 630 can be retracted in a direction away from the limiting groove 611, so that the pressure block 630 can still be closely attached to the part to be clamped, that is, the pressure block 630 can be adaptively adjusted according to different models and specifications of the part to be clamped, and can be used to clamp and position different models and specifications of the part to be clamped, thereby solving the technical problem of low applicability of the existing clamping tooling and having good versatility.

[0065] The present application also proposes a sensor production line, which includes an optical module adjustment jig. The specific structure of the optical module adjustment jig refers to the above-mentioned embodiment. Since the optical module adjustment jig adopts all the technical solutions of all the above-mentioned embodiments, it also has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0066] To sum up, the optical module adjustment fixture provided in the present application clamps the module bracket 910 on the clamping mechanism 600, and the grasping mechanism 400 is used to receive the component 920. At this time, the rotating mechanism 300 can drive the grasping mechanism 400 to rotate to adjust the direction of the receiving component 920, and determine the placement orientation of the receiving component 920 on the module bracket 910 according to the test results of the testing mechanism 500, so as to facilitate the subsequent direct installation of the receiving component 920 on the module bracket 910. The entire process is automatically coordinated and operated by the grasping mechanism 400, the lifting mechanism 200, the rotating mechanism 300 and the testing mechanism 500, etc., and the degree of automation is greatly improved, which greatly improves the adjustment efficiency of the optical module 900.

[0067] The above are merely optional embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included within the scope of the claims of the present application.
