Technical Field
[0001] This utility model relates to the field of testing equipment technology, and specifically to a line laser component testing device. Background Technology
[0002] As a core sensing component in products such as robotic vacuum cleaners and intelligent navigation devices, the laser module's power, linewidth, divergence angle, and other characteristic parameters directly determine the positioning accuracy and operational stability of the equipment. Therefore, it must undergo rigorous testing before leaving the factory.
[0003] In existing testing equipment, a specific test component needs to be set up for each type of line laser component, resulting in one test component being compatible with only one type of line laser component, causing inconvenience and increasing testing costs. In addition, the fixing fixtures for line laser components usually use a snap-fit structure to install and fix the line laser components, but over time, this can lead to structural fatigue, resulting in unstable fixing and affecting the accuracy of test data. Utility Model Content
[0004] The purpose of this utility model embodiment is to provide a line laser component testing device to solve the problems mentioned above, which can only be adapted to one type of line laser component, causing inconvenience and increasing testing costs. In addition, the fixing fixture of the line laser component usually adopts a snap-fit structure to realize the installation and fixing of the line laser component, but after a long time, it will lead to structural fatigue, resulting in unstable fixing and affecting the accuracy of test data.
[0005] To achieve the above objectives, this utility model provides a line laser component testing device, which includes: The mounting platform has a vertically mounted beam projection target surface with graduations. The mounting clamping mechanism is detachably mounted on the mounting platform via a limiting locking mechanism. The line laser assembly is mounted and fixed on the mounting platform via the mounting clamping mechanism to align with and project a beam onto the beam projection target surface. The mounting clamping mechanism comprises at least two types, each configured specifically for a particular type of line laser assembly, and each mounting clamping mechanism is structurally adapted to the corresponding type of line laser assembly. During testing, the mounting clamping mechanism is replaced according to the type of line laser assembly being tested. Multiple image capturing mechanisms are spaced apart on the mounting platform for aligning with and acquiring images from the target surface projected by the light beam.
[0006] Optionally, the line laser component testing equipment further includes: A light shield is disposed on the mounting platform. The light shield has a receiving cavity with an opening at one end. The beam projection target is disposed in the receiving cavity of the light shield. The projection beam of the line laser assembly is projected onto the beam projection target through the opening end of the light shield. Optionally, a compensating light source is provided inside the receiving cavity of the light-shielding plate to eliminate ambient light interference.
[0007] Optionally, the line laser assembly includes a line laser body; the mounting and clamping mechanism includes: Support plate; A mounting mechanism is provided on the support plate, and the mounting mechanism is provided with a first groove for accommodating the line laser body; A clamping mechanism is provided on the support plate and located on one side of the mounting mechanism. When the line laser body is placed in the first groove, the clamping mechanism clamps the line laser body, thereby fixing the line laser body on the mounting mechanism.
[0008] Optionally, the support plate is provided with at least two limiting engagement holes; The limiting engagement mechanism includes: At least two limiting engagement posts that match the limiting engagement holes are disposed on the mounting platform. The limiting engagement posts are inserted into the corresponding limiting engagement holes, so that the carrier plate can be detachably installed on the mounting platform.
[0009] Optionally, the clamping mechanism includes: Support frame; A tensioning rod is telescopically mounted on the support frame. The end of the tensioning rod that contacts the line laser body is provided with a protective protrusion. The protective protrusion is used to prevent damage to the line laser body during the process of tightening it. A handle is rotatably mounted on the support frame. The handle is connected to the tension rod via a connecting plate. Moving the handle can change the extension and retraction state of the tension rod.
[0010] Optionally, the mounting mechanism is provided with a through hole or a second groove, which communicates with the first groove. When the clamping rod is in the extended state, its clamping end passes through the through hole or the second groove to reach the position of the first groove.
[0011] Optionally, the connecting plate is an arc-shaped connecting plate, and the two ends of the connecting plate are respectively hinged to the handle and the tightening rod; The handle is provided with a receiving groove. When the tightening rod is in the extended state, the connecting plate is pushed by the extension of the tightening rod, so that the end of the connecting plate that is hinged to the handle and a portion thereof are confined within the receiving groove.
[0012] Optionally, the clamping rod includes: The mounting rod has a hollow interior at one end and is provided with an internal thread; An adjusting rod is provided with an external thread at one end.

[0013] Optionally, the line laser component testing equipment further includes: A display mechanism, connected to the image capturing mechanism, is used to display an image of the target surface on which the light beam is projected.
[0014] This solution uses corresponding mounting and tightening mechanisms to install and fix different line laser components, reducing structural fatigue of the mounting and tightening mechanisms after prolonged use and ensuring service life. The mounting and tightening mechanisms are positioned on the mounting platform via a limit locking mechanism, allowing for quick assembly and disassembly based on the type of line laser component under test. The overall structure is simple, easy to operate, and adaptable to different types of line laser components, significantly reducing testing costs and improving testing efficiency.

Detailed Implementation
[0018] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.
[0019] In this embodiment of the utility model, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use.
[0020] The terms “first,” “second,” “third,” etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0021] The terms "parallel" and "perpendicular" do not mean that the components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted. For example, "parallel" simply means that its direction is more parallel than "perpendicular," not that the structure must be completely parallel, but that it can be slightly tilted.
[0022] The terms "horizontal," "vertical," and "sag" do not imply that a component must be absolutely horizontal, vertical, or sagging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.
[0023] Furthermore, terms like "roughly" and "basically" are used to indicate that the content does not require absolute precision, but rather allows for a certain degree of deviation. For example, "roughly equal" does not simply mean absolute equality; in actual production and operation, achieving absolute "equality" is difficult, and a certain degree of deviation is generally present. Therefore, besides absolute equality, "roughly equal to" also includes the aforementioned situation where a certain degree of deviation exists. Using this as an example, in other cases, unless otherwise specified, terms like "roughly" and "basically" have similar meanings.
[0024] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figure 1 , Figure 4 As shown, this embodiment provides a line laser component testing device, which includes: Mounting platform 1, on which a beam projection target 2 is vertically mounted, and the beam projection target 2 is marked with scales; The mounting clamping mechanism 3 is detachably mounted on the mounting platform 1 via the limiting locking mechanism 4. The line laser assembly is mounted and fixed on the mounting platform 1 via the mounting clamping mechanism 3 to align with and project the beam onto the beam projection target surface 2. The mounting clamping mechanism 3 includes at least two types, each configured specifically for a particular type of line laser assembly, and each mounting clamping mechanism 3 is structurally compatible with the corresponding type of line laser assembly. During testing, the mounting clamping mechanism 3 is replaced according to the type of line laser assembly being tested. Multiple image capturing mechanisms 5 are spaced apart on the mounting platform 1 and aligned with the beam projection target 2 to acquire images of the beam projection target 2.
[0027] Specifically, in this embodiment, the mounting platform 1 has a certain height and width to facilitate testing operations. Furthermore, to enable a single line laser component testing device to test multiple different types of line laser components, this solution includes at least two types of mounting and clamping mechanisms 3. Each type of mounting and clamping mechanism 3 is configured specifically for mounting and fixing a particular type of line laser component, adapting to the structure of that type of line laser component. During testing, the mounting and clamping mechanism 3 can be replaced according to the type of line laser component; the structure of the line laser component refers to its external shape. Simultaneously, to facilitate installation and disassembly and ensure efficiency, the mounting and clamping mechanism 3 is detachably mounted on the mounting platform 1 via a limiting locking mechanism 4. The beam projection target surface 2 can directly use target values. Setting multiple image capturing mechanisms 5 to capture images simultaneously ensures a wider shooting angle, avoiding inaccuracies caused by only measuring the central area, thereby improving testing accuracy.
[0028] In one embodiment, the mounting clamping mechanism 3 and the multiple image capturing mechanisms 5 are all located on the same side of the beam projection target surface 2. At this time, the distance between the image capturing mechanism 5 and the mounting clamping mechanism 3 is 5cm; the distance between the mounting clamping mechanism 3 and the beam projection target surface 2 is about 50cm. This distance setting allows the beam with the best effect to be observed through the image capturing mechanism 5. In another embodiment, the mounting clamping mechanism 3 and the multiple image capturing mechanisms 5 are respectively located on both sides of the beam projection target surface 2.
[0029] In one embodiment, a mounting platform 1 is placed on a mounting frame, and a moving mechanism and a support and leveling mechanism are provided at the bottom of the mounting frame. The moving mechanism facilitates the movement of the line laser component testing equipment; the support and leveling mechanism supports the line laser component testing equipment and adjusts its levelness during testing. Specifically, taking a rectangular frame structure as an example, the moving mechanism includes four moving rollers, symmetrically arranged at the bottom of the mounting frame. During the movement of the line laser component testing equipment, the rolling of the rollers enables convenient and rapid movement, reducing manpower. In addition, the support and leveling mechanism consists of four bearing pads symmetrically arranged at the bottom of the mounting frame. When the line laser component testing equipment is moved to the designated position, the four bearing pads support the equipment, preventing displacement during testing and ensuring the test results are accurate. Furthermore, for easy movement and leveling, each bearing pad is threadedly connected to the mounting frame with bolts. Rotating the corresponding bearing pad allows it to rotate, adjusting its extension distance relative to the mounting frame. This adjusts the levelness of the mounting frame (line laser component testing equipment), ensuring that all line laser component testing equipment on the mounting platform 1 is level and guaranteeing testing accuracy.
[0030] In one implementation, such as Figure 1 As shown, the line laser component testing equipment also includes: a light-shielding plate 6, which is disposed on the mounting platform 1. The light-shielding plate 6 has a concave receiving cavity with one end open. The beam projection target surface 2 is disposed within the receiving cavity of the light-shielding plate 6. The projected beam of the line laser component is projected onto the beam projection target surface 2 through the open end of the light-shielding plate 6. Specifically, the light-shielding plate 6 is provided with a concave receiving cavity with one end open, and the beam projection target surface 2 is disposed within the receiving cavity, thereby protecting the beam projection target surface 2 and reducing the influence of external light, further improving the image quality captured by the image capturing mechanism 5.
[0031] In one embodiment, a compensation light source (not shown) is provided within the receiving cavity of the light-shielding plate 6 to eliminate ambient light interference, thereby improving the image quality captured by the image capturing mechanism 5. Specifically, the compensation light source can be a ring-shaped LED lamp with adjustable brightness.
[0032] In one implementation, such as Figure 2 , 5 As shown in Figure 6, the line laser assembly includes a line laser body and a line laser bundle. The line laser body is connected to a terminal block via the line laser bundle for power supply. The terminal block can be mounted on the mounting clamping mechanism 3 or on the mounting platform 1. The terminal block is connected to the power supply unit of the equipment, enabling the power supply unit to supply power to the line laser body. To facilitate quick installation and removal of the mounting clamping mechanism 3 when testing different types of line laser assemblies, the mounting clamping mechanism 3 is configured to include a support plate 31, with a mounting mechanism 32 and a clamping mechanism 33 on the upper surface of the support plate 31 for installing and fixing the line laser body, forming a modular design. Furthermore, the mounting mechanism 32 has a first groove 321 for accommodating the line laser body. The first groove 321 matches the shape of the line laser body, so that after installation, the line laser body is located within the first groove 321. The clamping mechanism 33 is located on one side of the mounting mechanism 32, fixing the line laser body to the mounting mechanism 32 by clamping. This method enables auxiliary positioning of the line laser body, ensuring a more stable installation and guaranteeing testing accuracy. Furthermore, to facilitate the installation and disassembly of the mounting clamping mechanism 3, a handle is provided on the support plate 31 for lifting the mounting clamping mechanism 3.
[0033] In one embodiment, since the mounting clamping mechanism 3 is configured specifically for a particular type of line laser body, adapting to the structure of the line laser body of that type of line laser assembly, and since at least two types of mounting clamping mechanisms 3 are included, the mounting clamping mechanism 3 can be replaced depending on the type of line laser assembly. Therefore, during use, such as Figure 2-4As shown, to ensure rapid installation and disassembly between the mounting clamping mechanism 3 and the limiting engagement mechanism 4, and to guarantee testing efficiency, each mounting clamping mechanism 3 has at least two limiting engagement holes 311 vertically formed on its supporting plate 31. These limiting engagement holes 311 can be through holes or non-through slots. Furthermore, the limiting engagement mechanism 4 includes at least two limiting engagement posts that match the limiting engagement holes 311, vertically positioned on the mounting platform 1. When the mounting clamping mechanism 3 is installed on the limiting engagement mechanism 4, the limiting engagement posts are inserted into the corresponding limiting engagement holes 311 to fix the mounting clamping mechanism 3 to the limiting engagement posts. When it is necessary to remove the mounting clamping mechanism 3 from the limiting engagement posts, it can be directly pulled out. Preferably, providing two limiting engagement posts and limiting engagement holes 311 effectively ensures stability after installation. The limiting engagement hole 311 and the limiting engagement post can be circular, elliptical, rectangular, or other structural forms. The specific quantity can be two or more.
[0034] In one implementation, considering that the testing process requires the tightening mechanism 3 to repeat the same loosening and tightening actions multiple times, therefore, as Figure 7 As shown, the clamping mechanism 33 includes: a support frame 331; a clamping rod 332, telescopically mounted on the support frame 331, with a protective protrusion 333 at the end of the clamping rod 332 that contacts the line laser body to prevent damage to the line laser body during clamping; and a handle 334, rotatably mounted on the support frame 331, connected to the clamping rod 332 via a connecting plate 335. Moving the handle 334 changes the extension / retraction state of the clamping rod 332. This design simplifies the overall mechanism, allowing for quick adjustment of the clamping rod 332's extension and retraction simply by moving the handle 334, facilitating rapid installation and disassembly of the line laser assembly. Furthermore, it effectively ensures that the clamping rod 332 clamps the line laser body, preventing vibration during testing. This structure effectively alleviates structural fatigue after prolonged use and prevents inaccurate test data due to insecure fixing of the line laser body.
[0035] Specifically, since the tensioning rod 332 will contact the line laser body when it is in the extended state, and with the support of the mounting mechanism 32, it will tighten the line laser body. Therefore, the end of the tensioning rod 332 will apply a certain pressure to the line laser body. Thus, a protective protrusion 333 made of soft materials such as rubber, silicone, and plastic is provided at the end of the tensioning rod 332 to protect the line laser body and prevent scratches or damage to the line laser body.
[0036] In one implementation, such as Figure 5-6As shown, in addition to setting a first groove 321 on the mounting mechanism 32 to limit the line laser body, a through hole 322 or a second groove 323 can also be opened on the mounting mechanism 32, and the through hole 322 or the second groove 323 communicates with the first groove 321. When the clamping rod 332 is in the extended state and clamps the line laser body, the clamping end of the clamping rod 332 passes through the through hole 322 or the second groove 323, reaches the position of the first groove 321, and contacts and clamps the line laser body, thereby effectively ensuring the fixing effect on the line laser body.
[0037] In one implementation, such as Figure 7 As shown, in order to ensure that the extension and retraction of the tensioning rod 332 can be controlled when the handle 334 is turned, the connecting plate 335 is an arc-shaped connecting plate, and the two ends of the connecting plate 335 are respectively hinged to the handle 334 and the tensioning rod 332 to achieve a rotatable connection; and a receiving groove 3341 is provided on the handle 334. When the tensioning rod 332 is in the extended state, the connecting plate 335 is pushed by the extension of the tensioning rod 332, so that the end of the connecting plate 335 that is hinged to the handle 334 and a part thereof are confined in the receiving groove 3341, thereby realizing the extension and retraction of the tensioning rod 332.
[0038] In one embodiment, since the mounting clamping mechanism 3 is configured specifically for a particular type of line laser assembly and is adapted to the structure of the line laser body of that type of line laser assembly, and since at least two types of mounting clamping mechanisms 3 are included, the mounting clamping mechanism 3 can be replaced according to the type of line laser assembly. Therefore, a mounting clamping mechanism 3 with a corresponding shape and structure matching the type of line laser assembly can be selected and installed on the limiting and locking mechanism 4. At this time, since the type of line laser assembly has changed, its structure will also change accordingly, and there may be slight differences in the position of the line laser body on the mounting clamping mechanism 3. In order to adapt to different types of line laser assemblies and achieve clamping and fixing of the line laser body, such as... Figure 7 As shown, the clamping rod 332 is configured to include: a mounting rod 3321, one end of which is hollow and has an internal thread; and an adjusting rod 3322, one end of which has an external thread. The adjusting rod 3322 and the mounting rod 3321 are rotatably and detachably connected by the thread. The mounting rod 3321 can be replaced according to the type of the line laser assembly, and the elongation of the adjusting rod 3322 can be adjusted by rotating the adjusting rod 3322.
[0039] In one implementation, such as Figure 1As shown, the line laser component testing equipment also includes a display mechanism 7, connected to the image capturing mechanism 5, for displaying the image of the beam projection target surface 2. After the image capturing mechanism 5 captures the image on the beam projection target surface 2, the display mechanism 7 is set up to intuitively display the test results of the line laser component.

Within the scope of the technical concept of the present utility model, various simple modifications can be made to the technical solutions of the present utility model, and these simple modifications all fall within the protection scope of the present utility model.
[0041] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the various possible combinations will not be described separately in this embodiment.
[0042] Furthermore, various different implementation methods of this utility model can be arbitrarily combined, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
