Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] Please see Figures 1 to 7 This application provides an installation fixture, which includes a fixed bracket 400 for holding an emitting element, a moving mechanism 200 for driving the fixed bracket 400 to move, a testing mechanism 500 for testing the emitting element, and a clamping mechanism 600 for holding an optical module bracket 800. The testing mechanism 500 and the moving mechanism 200 are arranged at intervals along a first direction a and are located on opposite sides of the clamping mechanism 600. The optical module bracket 800 is provided with a light-transmitting hole 810, which extends along the first direction a. The moving mechanism 200 is used to drive the fixed bracket 400 to move toward the optical module bracket 800 so that the light emitted by the emitting element passes through the light-transmitting hole 810 and illuminates the testing mechanism 500. The moving mechanism 200 is also used to drive the fixed bracket 400 to move toward the optical module bracket 800 along the first direction a so that the emitting element extends into the light-transmitting hole 810.

[0032] It should be noted that the emitting element in this embodiment is an important component of the optical module. The optical module typically includes an optical module support 800 and structures such as emitting elements and receiving elements mounted on the optical module support 800. When the optical module is applied to a sensor, a laser beam is emitted towards the object under test through the emitting element, and then the receiving element receives the beam reflected back from the object under test. After appropriate processing, relevant information about the object under test can be obtained, thereby enabling the detection, tracking, and identification of the object under test.

[0033] The mounting fixture provided in this application clamps the optical module bracket 800 onto the clamping mechanism 600, while the fixed bracket 400 is used to clamp the emitting element. The moving mechanism 200 can drive the fixed bracket 400 to move to correspond with the optical module bracket 800. At this time, the light emitted by the emitting element can pass through the light-transmitting hole 810 on the optical module bracket 800 and illuminate the testing mechanism 500 to test the emitting element. After the test is completed, the moving mechanism 200 can also drive the fixed bracket 400 to move along the first direction a toward the optical module bracket 800, so that the emitting element extends into the light-transmitting hole 810, making it convenient to install the emitting element into the light-transmitting hole 810. In this way, the testing and installation of the emitting element can be realized on one fixture, which effectively improves the production efficiency of the sensor.

[0034] Understandably, the installation fixture in this application embodiment also includes a controller (not shown in the figure). The controller is communicatively connected to the moving mechanism 200 and the testing mechanism 500. The controller controls the moving mechanism 200 and the testing mechanism 500 to automatically cooperate and operate, which greatly improves the degree of automation.

[0035] In some embodiments, such as Figure 2 As shown, the fixed bracket 400 has a fixed cavity 421 for accommodating the emitting element. The emitting element is secured within the fixed cavity 421, and the opening of the fixed cavity 421 faces the test mechanism 500. By securing the emitting element within the fixed cavity 421, the cavity wall of the fixed cavity 421 can limit the emitting element, thereby stabilizing the fixed state of the emitting element and ensuring that the test of the emitted beam from the emitting element is not affected.

[0036] Furthermore, the fixed bracket 400 includes a fixed rod 410 and a mounting rod 420 connected to each other. Both the fixed rod 410 and the mounting rod 420 extend along the first direction a. The fixed rod 410 is connected to the moving mechanism 200. A fixed cavity 421 is provided at the end of the mounting rod 420 facing the testing mechanism 500. The mounting rod 420 has a wiring hole 422 communicating with the fixed cavity 421. By providing the wiring hole 422, cables can pass through it. The cables are connected to the transmitting element, and the transmitting element is connected to the controller via the cables, enabling the transmitting element to work normally and allowing control over the time, intensity, and duration of light emission.

[0037] Specifically, the fixed rod 410 is detachably connected to the moving mechanism 200. The fixed rod 410 can be provided with mounting holes 411. The fixed rod 410 and the moving mechanism 200 are detachably connected through the mounting holes 411 and fasteners, thereby facilitating the assembly and disassembly of the fixed bracket 400.

[0038] Specifically, the testing unit 500 is a beam quality analyzer, which can analyze and calibrate the beam quality emitted by the emitting element. The main analysis includes the roundness of the beam and whether the center point of the beam spot is the point with the highest brightness.

[0039] The emitting element can be a semiconductor laser diode, which is a device that converts electrical energy into laser light. Compared with other types of lasers, semiconductor laser diodes are smaller, lighter, and can withstand greater mechanical vibration and impact, thus having higher reliability.

[0040] In some embodiments, the mounting fixture further includes a linear drive mechanism 700, on which the test mechanism 500 is slidably disposed. The linear drive mechanism 700 is used to drive the test mechanism 500 to move along a first direction a, so that the test mechanism 500 moves closer to or away from the receiving element.

[0041] By setting up the linear drive mechanism 700, the distance between the test mechanism 500 and the transmitting element can be adjusted according to the actual situation, thereby making the test results more accurate. Specifically, the linear drive mechanism 700 of this application can be a linear motor.

[0042] In some embodiments, such as Figure 1 and Figure 3 As shown, the mounting fixture also includes a support 100, and the moving mechanism 200 includes a first adjusting platform 210, a second adjusting platform 220, and a lifting structure 230. The first adjusting platform 210 is mounted on the support 100, the second adjusting platform 220 is mounted on the first adjusting platform 210, and the lifting structure 230 is mounted on the second adjusting platform 220. The first adjusting platform 210 is used to adjust the position of the second adjusting platform 220 along a first direction a, and the second adjusting platform 220 is used to adjust the position of the lifting structure 230 along a second direction b. The first direction a and the second direction b are perpendicular. Specifically, the first adjusting platform 210 and the second adjusting platform 220 can be manual fine-tuning slides. Manual fine-tuning slides are existing technology and will not be described in detail here.

[0043] Specifically, in this embodiment, the lifting structure 230 drives the fixed bracket 400 to move along a third direction c, which is perpendicular to the horizontal plane, i.e., the third direction c is vertical. The first direction a and the second direction b are parallel to the horizontal plane and perpendicular to each other. By setting the moving structure, the lifting structure 230 can move along the first direction a and the second direction b. Then, the fixed bracket 400 and the transmitting element can move synchronously with the lifting structure 230. Thus, the fixed bracket 400 can not only move in various directions on the horizontal plane, but also rise and fall in the vertical direction, giving the fixed bracket 400 a higher degree of freedom.

[0044] Specifically, a limiting plate 240 can be provided on the top of the lifting structure 230. The limiting plate 240 is fixedly connected to the lifting structure 230, and one side wall of the limiting plate 240 abuts against the fixed bracket 400, thereby limiting the fixed bracket 400.

[0045] In some embodiments, such as Figure 4 As shown, the lifting structure 230 includes a base 231, a lifting seat 232 slidably mounted on the base 231 along a third direction c, and an adjustment component for adjusting the lifting of the lifting seat 232. A fixed bracket 400 is connected to the lifting seat 232. The adjustment component includes a rotating rod 2331 and an adjusting block 2332. The adjusting block 2332 is rotatably connected to the side wall of the base 231. One end of the adjusting block 2332 abuts against the lifting seat 232, and the other end abuts against the rotating rod 2331. The rotating rod 2331 is used to push the adjusting block 2332 to rotate, thereby moving the lifting seat 232 along the third direction c. By setting the adjustment component, simply turning the rotating rod 2331 is enough to move the lifting seat 232 along the third direction c, thereby synchronously raising and lowering the fixed bracket 400 along the third direction c. The adjustment method is simple and improves the convenience of adjustment.

[0046] Furthermore, a connecting seat 2311 is provided on the side wall of the base 231. The connecting seat 2311 protrudes from the side wall of the base 231. The rotating rod 2331 is movably inserted through the connecting seat 2311. Specifically, the rotating rod 2331 can be threadedly connected to the connecting seat 2311. Therefore, by turning one end of the rotating rod 2331, the rotating rod 2331 can be moved along the axial direction. The edge of the adjusting block 2332 is provided with an abutting part 2334 and a pushing part 2335. The pushing part 2335 abuts against the bottom of the lifting seat 232. One end of the rotating rod 2331 abuts against the abutting part 2334. When the rotating rod 2331 moves along the axial direction, it can push the abutting part 2334 to rotate, thereby driving the pushing part 2335 to rotate synchronously and pushing the lifting seat 232 to move along the third direction c.

[0047] Specifically, the bottom of the lifting seat 232 is provided with a connecting column 2321, and the pushing part 2335 abuts against the connecting column 2321. When the pushing part 2335 rotates counterclockwise, it can push the connecting column 2321 upward, thereby driving the lifting seat 232 to move upward in the vertical direction.

[0048] In some embodiments, such as Figures 5 to 7As shown, the clamping mechanism 600 includes a base plate 610, a fixing seat 620 fixed on the base plate 610, a pressure block 630 slidably disposed on the base plate 610, an elastic connector 640 disposed between the fixing seat 620 and the pressure block 630, and a stop wall 615 disposed on the base plate 610. The base plate 610 is provided with a limiting groove 611 for placing an optical module bracket 800. The limiting groove 611 is used to limit the optical module bracket 800. The pressure block 630 is disposed between the fixing seat 620 and the optical module bracket 800. One end of the elastic connector 640 is fixed to the fixing seat 620, and the other end of the elastic connector 640 is elastically connected to the pressure block 630 so that the pressure block 630 elastically abuts against the optical module bracket 800. The stop wall 615 is disposed on the side of the optical module bracket 800 away from the pressure block 630 so as to clamp the optical module bracket 800 together with the pressure block 630 along the first direction a.

[0049] The limiting groove 611 can limit the optical module bracket 800. By setting the pressure block 630 between the fixing base 620 and the optical module bracket 800, the pressure block 630 can extend towards the limiting groove 611 or retract away from the limiting groove 611, so that for optical module brackets 800 of different sizes, the end of the pressure block 630 facing the optical module bracket 800 can always be tightly attached to and abut against the clamping part. This allows for adaptive adjustment according to different models and specifications of optical module brackets 800, solving the technical problem of low applicability of existing clamping fixtures, improving versatility and expanding the applicability of the clamping structure.

[0050] In some embodiments, the mounting base 620 has a mounting hole 623 on the side facing the optical module bracket 800. The end of the elastic connector 640 facing away from the pressure block 630 passes through the mounting hole 623 and is fixed to the mounting hole 623, thereby making the elastic connector 640 firmly fixed and preventing it from detaching when the pressure block 630 acts on the optical module bracket 800. The elastic connector 640 has a simple structure, which not only facilitates the opening of the pressure block 630 to place the optical module bracket 800, but also makes it suitable for clamping and positioning optical module brackets 800 of different models and specifications.

[0051] Specifically, the elastic connector 640 is a spring-loaded pin. The spring-loaded pin may include a needle tube 641, a needle shaft 642, and a spring (not shown in the figure). The needle tube 641 has an internal cavity, and the needle shaft 642 is disposed in the cavity with one end extending out of the needle tube 641. The needle shaft 642 can move axially along the needle tube 641. One end of the spring abuts against the head of the needle shaft 642, and the other end abuts against the bottom wall of the needle tube 641. The end of the needle shaft 642 is connected to the pressure block 630, thereby making the pressure block 630 retractable.

[0052] Furthermore, a guide structure (not shown in the figure) can be provided inside the needle tube 641. The needle shaft 642 is guided and cooperated with the guide structure inside the needle tube 641. The guide structure can guide the needle shaft 642 when it moves along the axial direction of the needle tube 641, reducing the possibility of the needle shaft 642 deviating, thereby reducing the possibility of the pressure block 630 deviating and ensuring the straightness of the movement of the pressure block 630.

[0053] In some embodiments, two elastic connectors 640 are provided, each connected to one end of the pressure block 630. The two elastic connectors 640 extend in parallel directions and are symmetrical to each other. This allows the force exerted by the elastic connectors 640 on the pressure block 630 to be more even, preventing the pressure block 630 from shifting to one side during movement and ensuring the straightness of the pressure block 630's movement. Of course, in other possible embodiments, three, four, five, six, or more elastic connectors 640 can be provided. This application does not impose a unique limitation on the number of elastic connectors 640.

[0054] Furthermore, the position of the elastic connector 640 connected to the pressure block 630 can 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 pressure block 630 can form an equilateral triangle by connecting the ends of the three elastic connectors 640, thereby making the force exerted by the elastic connectors 640 on the pressure block 630 more balanced.

[0055] In this embodiment, the shape of the limiting groove 611 is adapted to the shape of the optical module bracket 800. Understandably, since the optical module bracket 800 may be an irregularly shaped part, the shape of the limiting groove 611 can also be correspondingly set to an irregular shape. This not only further improves the limiting effect on the optical module bracket 800, but also facilitates the operator in placing the optical module bracket 800 within the limiting groove 611 without interference.

[0056] In some embodiments, the top surface of the base plate 610 is further provided with a placement groove 612, the fixing seat 620 and the pressure block 630 are disposed 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] Understandably, both the placement groove 612 and the limiting groove 611 are formed 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. Therefore, the height of the mounting position of the pressure block 630 is less than the height of the mounting position of the optical module bracket 800. Thus, when the pressure block 630 abuts against the optical module bracket 800, the optical module bracket 800 can contact the center position of the pressure block 630, allowing the pressure block 630 to better apply force to the optical module bracket 800, further improving the clamping effect.

[0058] Furthermore, the base plate 610 also includes a baffle 613 connecting the bottom wall of the placement groove 612 and the bottom wall of the limiting groove 611. The baffle 613 faces the surface of the pressing block 630 and is perpendicular to the moving direction of the pressing block 630. The baffle 613 is used to block 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 baffle 613 will be formed between the bottom wall of the placement groove 612 and the bottom wall of the limiting groove 611. The baffle 613 is located in the moving stroke of the pressure block 630. When the optical module bracket 800 is placed in the limiting groove 611, the side of the optical module bracket 800 facing the pressure block 630 will extend beyond the baffle 613. Therefore, the pressure block 630 will abut against the optical module bracket 800 but not against the baffle 613. The function of the baffle 613 is to prevent the pressure block 630 from extending too far and causing damage to the optical module bracket 800.

[0060] In some embodiments, the mounting base 620 is detachably connected to the base plate 610, and the position of the mounting base 620 is adjustable along the direction from the pressure block 630 toward the optical module bracket 800.

[0061] The mounting base 620 is detachably connected to the base plate 610, making it easy to replace. Furthermore, since the position of the mounting base 620 is adjustable along the direction from the pressure block 630 towards the optical module bracket 800, its position can be adjusted according to actual needs. For example, when the lateral dimension of the optical module bracket 800 placed in the limiting groove 611 is small, the mounting base 620 can be installed closer to the limiting groove 611, resulting in better clamping performance. Conversely, when the lateral dimension of the optical module bracket 800 placed in the limiting groove 611 is large, the mounting base 620 can be installed further away from the limiting groove 611, allowing the pressure block 630 sufficient retraction space. In other words, the installation position of the mounting base 620 can be adaptively adjusted according to different models and specifications of optical module brackets 800, further improving the applicability of the clamping fixture.

[0062] Specifically, a waist-shaped hole 621 can be opened on the fixed base 620, and a positioning hole 614 corresponding to the waist-shaped hole 621 is opened on the base plate 610. The installation position of the fixed base 620 can be adjusted by fasteners passing through the waist-shaped hole 621 and the positioning hole 614 respectively.

[0063] In some embodiments, the top surface of the fixing base 620 is provided with a connecting hole 622, and the mounting fixture also includes a fastener (not shown in the figure). The fastener is movably inserted through the connecting hole 622 and is used to abut 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 this application is as follows: The pressure block 630 is manually pulled towards the fixed base 620, and then the optical module bracket 800 is placed horizontally on the base plate 610, so that the optical module bracket 800 is accommodated in the limiting groove 611, and the inner wall of the limiting groove 611 abuts against the side of the optical module bracket 800; since the pressure block 630 is telescopically connected to the fixed base 620, for optical module brackets 800 with smaller lateral dimensions, the pressure block 630 can extend towards the limiting groove 611. This allows the clamping block 630 to fit snugly against the optical module bracket 800. For optical module brackets 800 with larger lateral dimensions, the clamping block 630 can retract in the direction away from the limiting groove 611, so that the clamping block 630 can still fit snugly against the bracket to be clamped. That is, the clamping block 630 can be adaptively adjusted according to different models and specifications of optical module brackets 800, and can be used to clamp and position optical module brackets 800 of different models and specifications. This solves the technical problem of low applicability of existing clamping fixtures and has good versatility.

[0065] This application also proposes a sensor production line, which includes an installation fixture. The specific structure of the installation fixture is as described in the above embodiments. Since this installation fixture adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0066] In summary, the mounting fixture provided in this application clamps the optical module bracket 800 onto the clamping mechanism 600, while the fixed bracket 400 is used to clamp the emitting element. The moving mechanism 200 can drive the fixed bracket 400 to move to correspond with the optical module bracket 800. At this time, the light emitted by the emitting element can pass through the light-transmitting hole 810 on the optical module bracket 800 and illuminate the testing mechanism 500 to test the emitting element. After the test is completed, the moving mechanism 200 can also drive the fixed bracket 400 to move along the first direction a toward the optical module bracket 800, so that the emitting element extends into the light-transmitting hole 810, making it convenient to install the emitting element into the light-transmitting hole 810. In this way, the testing and installation of the emitting element can be realized on one fixture, effectively improving the production efficiency of the sensor.

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