Description

Technical Field

[0001] This application relates to the field of laser measurement equipment technology, and in particular to a laser ranging device. Background Technology

[0002] Cardboard and acrylic sheets are widely used due to their lightweight and ease of processing. To meet product structural design requirements, slotting is a crucial processing step. For example, in packaging, cardboard slotting allows for folding and shaping, facilitating transportation and storage; in the display industry, acrylic sheet slotting is used to embed LED strips or fix components, enhancing visual appeal; and in electronic devices, slotting design is used for circuit layout or heat dissipation optimization. These applications all rely on precise slotting, and the geometric parameters of the slots (such as width, depth, and spacing between adjacent slots) directly affect the functionality and reliability of the product. Therefore, after processing, the geometric parameters of the slots need to be measured to promptly detect dimensional deviations and prevent defective products from entering the next process.

[0003] In traditional measurement methods, the size of the slot is often measured using laser rangefinders. However, the components of traditional laser rangefinders are often scattered. For example, the rangefinder and the drive unit that moves the rangefinder are placed directly on a fixed table in the workshop. The rangefinder and the drive unit are connected to adjacent computer equipment through cables. The scattered arrangement of these components results in a large overall size of the equipment, which occupies a large area. Furthermore, the scattered arrangement makes it inconvenient to move the equipment and results in poor flexibility.

[0004] Based on this, this application provides a laser ranging device to solve the above-mentioned technical problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] This application provides a laser ranging device for reducing device size and improving device flexibility. The specific implementation process of this application is described below.

[0038] Please see Figures 1-7 This application provides a laser ranging device, comprising:

[0039] The system comprises a support 01, an X-axis travel assembly 02, a Y-axis travel assembly 03, an analysis and processing device 04, and a laser rangefinder 05. A placement plate 06 is installed inside the support 01. The analysis and processing device 04 is located inside the support 01, and an adsorption assembly 07 is installed on the placement plate 06 to fix the object to be tested. The X-axis travel assembly 02 is fixed on the placement plate 06, the Y-axis travel assembly 03 is mounted on the X-axis travel assembly 02, and the laser rangefinder 05 is located above the adsorption assembly 07 and connected to the Y-axis travel assembly 03. The analysis and processing device 04 is located inside the support 01 and is electrically connected to the X-axis travel assembly 02, the Y-axis travel assembly 03, and the laser rangefinder 05. The analysis and processing device 04, in conjunction with the laser rangefinder 05, is used to measure the width and depth of the groove on the object to be tested.

[0040] Bracket 01 features an aluminum alloy frame with an anodized surface, offering both lightweight construction and corrosion resistance. Pre-drilled mounting slots on bracket 01 allow for quick assembly and disassembly of modular components.

[0041] The placement plate 06 is horizontally positioned in the middle of the support 01. An adsorption component 07 is installed in a specific area on the placement plate 06. The adsorption component 07 can fix the item to be tested, which can be cardboard, acrylic sheet, wooden board, metal plate, etc. The adsorption component 07 can employ vacuum adsorption, magnetic adsorption, or other suitable adsorption methods.

[0042] An X-axis travel assembly 02 is fixed on the placement plate 06, and a Y-axis travel assembly 03 is connected to the X-axis travel assembly 02. The X-axis travel assembly 02 controls the movement of the Y-axis travel assembly 03 along the X-axis direction. The Y-axis travel assembly 03 and the X-axis travel assembly 02 are arranged perpendicularly to each other. A laser rangefinder 05 is connected to the Y-axis travel assembly 03, and the Y-axis travel assembly 03 controls the movement of the laser rangefinder 05 along the Y-axis direction. Thus, the position of the laser rangefinder 05 can be controlled to change in the horizontal direction through the X-axis travel assembly 02 and the Y-axis travel assembly 03. Both the Y-axis travel assembly 03 and the laser rangefinder 05 are located above the adsorption assembly 07, and the end of the Y-axis travel assembly 03 is connected to the X-axis travel assembly.

[0043] The laser rangefinder 05 is also equipped with a camera module, which makes it easy to take pictures and record the position of the laser beam on the cardboard. The laser rangefinder 05 supports ±45° angle fine adjustment to ensure that the laser beam is perpendicular to the groove to be measured.

[0044] The analysis and processing device 04 precisely controls the movement of the laser rangefinder 05 in the XY plane by sending control commands to the X-axis travel assembly 02 and the Y-axis travel assembly 03, enabling the laser rangefinder 05 to accurately align with different measurement points on the groove of the object being measured. Simultaneously, the analysis and processing device 04 calculates the width and depth of the groove based on the data measured by the laser rangefinder 05.

[0045] The analysis and processing device 04 has control and data processing functions, and can be a microcontroller, a computer, or a logic controller (PLC), etc. This application does not limit the specific selection of the analysis and processing device 04, and the actual feasible one shall prevail.

[0046] In this application, by setting a placement plate 06 inside the bracket 01, setting an X-axis travel assembly 02 on the placement plate 06, connecting a Y-axis travel assembly 03 to the X-axis travel assembly 02, and fixing a laser rangefinder 05 to the Y-axis travel assembly 03, and setting an adsorption assembly 07 on the placement plate 06 for fixing the object to be tested, and setting an analysis and processing device 04 inside the bracket 01, the analysis and processing device 04 is electrically connected to the X-axis travel assembly 02, the Y-axis travel assembly 03, and the laser rangefinder 05, all components are integrated inside the bracket 01, realizing the integration of all components, solving the problem of the large overall size of the equipment caused by the dispersion of components in the prior art, reducing the occupied area, and facilitating the overall movement of the equipment due to its integration inside the bracket 01, thus improving the flexibility of the equipment.

[0047] The analysis and processing device 04 also has programming and storage functions, which facilitates operators to set different measurement processes according to different specifications of the test items. The analysis and processing device 04 can be assembled or designed using existing components based on functional requirements to achieve the purpose of this application. Existing components include microcontrollers (MCUs), communication interface chips, and memory. In addition, since all components are integrated on the bracket 01, the measurement process of the slot parameters can be completed by a single person, reducing labor costs.

[0048] In traditional laser rangefinding, clamping methods are commonly used to fix the object to be measured. For example, weights are used to hold the edge of cardboard, or clamps and bolts are used to secure the cardboard to its edge. These clamping methods can easily deform the cardboard, leading to damage. Therefore, this application uses an adsorption method to fix the object to be measured, reducing damage to the cardboard. The specific description is as follows:

[0049] When the test item is fixed by adsorption, in an optional embodiment, the adsorption assembly 07 includes an adsorption plate 08, an adsorption cover 09 and an air suction device 10. The adsorption plate 08 is disposed on the placement plate 06, the adsorption cover 09 is disposed on the lower surface of the placement plate 06, the adsorption holes on the adsorption plate 08 are connected to the adsorption cover 09, and the air suction device 10 is connected to the adsorption cover 09.

[0050] The adsorption plate 08 is made of porous ceramic material (porosity ≥ 40%), and its surface is precision ground (roughness Ra ≤ 0.8 μm) to ensure a tight seal when in contact with the sample. The adsorption holes on the adsorption plate 08 have a diameter of 0.3 mm-0.8 mm and are distributed in a hexagonal close-packed pattern. The hole spacing can be 5 mm or 2 cm. The specific hole spacing is not limited here and will be determined based on what is actually feasible.

[0051] An adsorption cover 09 is connected to the lower part of the adsorption plate 08. The adsorption plate 08 is located on the upper surface of the placement plate 06. The adsorption cover 09 penetrates the placement plate 06 downwards and is located below the placement plate 06. The connection edge between the adsorption plate 08 and the adsorption cover 09 is sealed by means of glue, sealing ring, etc., to improve the adsorption effect.

[0052] The air suction device 10 is connected to the adsorption hood 09 via the adsorption tube 12. Specifically, an adsorption cavity is formed between the adsorption hood 09 and the adsorption plate 08. The adsorption tube 12 communicates with the adsorption cavity, and the adsorption holes communicate with the adsorption cavity. When the air suction device 10 is running, the air pressure in the adsorption cavity drops rapidly, forming a uniform negative pressure field on the surface of the adsorption plate 08 through the adsorption holes. After the item to be tested is placed, the adsorption holes directly contact the bottom surface of the item, and fixation is achieved through negative pressure adsorption force. The air suction device 10 can be, for example, an electric air pump or a negative pressure air pump.

[0053] In this embodiment, the air suction device 10 cooperates with the adsorption cover 09 to form a negative pressure field on the surface of the adsorption plate through the adsorption holes, and the test item above the adsorption plate is attracted through the adsorption holes, thereby fixing the test item. Compared with the clamping method of the prior art, this application can reduce the deformation of the cardboard and reduce the damage of the cardboard.

[0054] Furthermore, it eliminates the need for additional components (such as gravity blocks or clamping devices) for fixation, reducing complexity, further improving efficiency, and providing convenience for operators.

[0055] In this optional embodiment, a limiting plate 11 is provided on the adsorption plate 08, and the limiting plate 11 is fixed around the adsorption plate 08. In this embodiment, the function of the limiting plate 11 is to position the item to be tested. There are three limiting plates 11, which are respectively connected in three directions of the adsorption plate 08. The area enclosed by the three limiting plates 11 is the location of the adsorption hole. In practice, the item to be tested (cardboard or acrylic plate) is placed in the location of the adsorption hole, and the edge of the item to be tested is abutted against the limiting plate 11. Another function of the limiting plate 11 is to prevent the item to be tested from moving during the measurement process.

[0056] The limiting plate 11 and the adsorption plate 08 are connected by bolts. The position of the limiting plate 11 can be moved to accommodate different sizes of test items.

[0057] Please continue reading. Figures 5-6 When dealing with test items of different sizes, especially small test items, some adsorption holes do not contact the test items, resulting in waste of resources. Based on this, in this optional embodiment, multiple independent adsorption chambers are formed between the adsorption cover 09 and the adsorption plate 08, and each adsorption chamber is connected to the air suction device 10 through an adsorption tube 12.

[0058] Each adsorption chamber corresponds to a region of the adsorption plate 08. The regions corresponding to the adsorption chambers do not overlap. Each adsorption chamber is connected to an adsorption tube 12 and an air suction device 10. A solenoid valve is installed on each adsorption tube 12. The solenoid valve is electrically connected to the analysis and processing device 04. The analysis and processing device 04 controls the corresponding adsorption tube 12 to be connected according to the size and specifications of the item to be tested, so that only the adsorption holes below the item to be tested are operated, while the other adsorption holes are not operated, thereby reducing resource waste.

[0059] For example Figure 5 In the process, the adsorption plate 08 is divided into 6 regions (namely ①, ②, ③, ④, ⑤, and ⑥). Each of the 6 regions extends an adsorption tube 12 that is connected to the air suction device 10. When the size of the object to be tested (such as cardboard) is the same as the size of the entire adsorption plate 08, the adsorption tubes 12 of all 6 regions need to operate simultaneously. When the size of the cardboard is equal to the sum of the sizes of regions ① and ②, the adsorption tubes 12 of regions ① and ② are connected simultaneously, while the adsorption tubes 12 of the other regions are not connected.

[0060] In an optional embodiment, the laser ranging device further includes a surrounding plate 13 and a base plate 14. The surrounding plate 13 is fixed to the side of the bracket 01, the base plate 14 is fixed to the bottom of the bracket 01, and the analysis and processing device 04 is disposed on the base plate 14.

[0061] The placement plate 06 divides the support 01 into upper and lower parts. In the upper part, the surrounding plate 13 is only connected to three sides of the support 01, leaving the front open for operators to easily pick up and measure the cardboard. In the lower part, the surrounding plate 13 is connected to four sides of the support 01. These four sides of the surrounding plate 13 cooperate with the base plate 14 to form a space in the lower part of the support 01. The analysis and processing device 04 is located in this space and is fixedly connected to the base plate 14.

[0062] Specifically, the aforementioned air suction device 10 is also fixedly connected to the base plate 14.

[0063] In this optional embodiment, the laser ranging device further includes a cooling fan. The enclosure 13 has ventilation holes, and the cooling fan is connected to the enclosure 13 and aligned with the ventilation holes. In this embodiment, the cooling fan and ventilation holes facilitate heat dissipation for the analysis and processing device 04. The cooling fan is connected to the enclosure 13 by screws.

[0064] In an optional embodiment, an operation panel 15 is also provided on the bracket 01. The operation panel 15 is fixed on the bracket 01 and electrically connected to the analysis and processing device 04. In this embodiment, the operation panel 15 is provided on the bracket 01. The operation panel 15 can not only display parameters but also be operated by the operator. The operator can input preset programs into the analysis and processing device 04 through the operation panel 15, and can also directly set the operating parameters of the X-axis travel component 02 and the Y-axis travel component 03 through the operation panel 15.

[0065] In an optional embodiment, a drawer 16 is provided on the lower surface of the placement board 06. The drawer 16 is located on the front of the support 01 (i.e., the side where the operator stands and operates the cardboard). By providing the drawer 16, it is convenient for the operator to place some commonly used tools, such as screwdrivers, measuring tapes, etc.

[0066] In an optional embodiment, the bottom of the bracket 01 is provided with casters 17 and legs 18, the height of which is adjustable. The legs 18 are height-adjustable through a folding or telescopic mechanism. When the bracket 01 needs to be moved, the legs 18 are retracted, allowing the casters 17 to contact the ground. At this time, applying external force to push the bracket 01 causes the casters 17 to slide on the ground, facilitating the movement of the bracket 01, saving manpower, and improving flexibility. When moved to a designated position, the legs 18 are extended, supporting the ground and restricting the movement of the bracket 01. Specifically, the legs 18 are located next to the casters 17, and the number of legs 18 is the same as the number of casters 17.

[0067] Please continue reading. Figure 7 In an optional embodiment, one or both of the X-axis travel assembly 02 and the Y-axis travel assembly 03 adopt the following structure, including:

[0068] The components include a travel frame 19, a servo motor 20, a ball screw, and a sliding plate 21. The ball screw is installed inside the travel frame 19, and the sliding plate 21 is installed on the travel frame 19 and connected to the ball screw. The servo motor 20 is fixed on the travel frame 19 and connected to the ball screw. The servo motor 20 and the ball screw work together to drive the sliding plate 21 to move.

[0069] The travel frame 19 has an internal mounting groove and guide rail mounting surfaces on both sides. The sliding plate 21 is located on the mounting surface and connected to the ball screw in the mounting groove. The travel frame 19 is connected to the placement plate 06 by leveling bolts to ensure that the travel frame 19 is level.

[0070] The ball screw is installed in the mounting groove, and both ends of the ball screw are fixed and supported by bearings. The ball screw is connected to the servo motor 20 through a shaft coupling, and the servo motor 20 is electrically connected to the analysis and processing device 04.

[0071] In actual operation, the servo motor 20 receives pulse signals from the controller and drives the ball screw to rotate. The ball screw converts its rotational motion into the linear motion of the sliding plate 21.

[0072] The testing process for this application is as follows:

[0073] First, the item to be tested is placed on the adsorption assembly 07 of the placement plate 06. The adsorption assembly 07 fixes the item to be tested by adsorption. Then, the laser rangefinder 05 is precisely aligned with the groove on the item to be tested by the X-axis travel assembly 02 and the Y-axis travel assembly 03. Next, the laser rangefinder 05 is activated and emits a laser beam towards the item to be tested (during which the laser rangefinder 05 moves and measures on the groove by the X-axis travel assembly and the Y-axis travel assembly). The information fed back by the laser beam is transmitted to the analysis and processing device 04. Finally, the analysis and processing device 04 calculates the depth and width of the groove on the item to be tested. After the parameters of the groove are measured, the air suction device 10 can be paused or air can be blown into the adsorption hole by the air suction device so that the operator can remove the item to be tested from the adsorption plate.

The servo motor 20 is fixed to the travel frame 19 and connected to the ball screw, cooperating to drive the sliding plate 21 to move. The travel frame 19 has an internal mounting groove and guide rail mounting surfaces on both sides. The sliding plate 21 is located on these mounting surfaces and connected to the ball screw within the mounting groove. The travel frame 19 is connected to a placement plate 06 via leveling bolts to ensure its horizontal position. The ball screw is housed within the mounting groove, with both ends fixed and supported by bearings. The ball screw is connected to the servo motor 20 via a coupling, and the servo motor 20 is electrically connected to the analysis and processing device 04. In operation, the servo motor 20 receives pulse signals from the controller, driving the ball screw to rotate. The ball screw converts its rotational motion into linear motion of the sliding plate 21.

[0078] Example 2:

[0079] The system comprises a support 01, an X-axis travel assembly 02, a Y-axis travel assembly 03, an analysis and processing device 04, and a laser rangefinder 05. A placement plate 06 is installed inside the support 01. The analysis and processing device 04 is located inside the support 01, and an adsorption assembly 07 is installed on the placement plate 06 to fix the object to be tested. The X-axis travel assembly 02 is fixed on the placement plate 06, the Y-axis travel assembly 03 is mounted on the X-axis travel assembly 02, and the laser rangefinder 05 is located above the adsorption assembly 07 and connected to the Y-axis travel assembly 03. The analysis and processing device 04 is located inside the support 01 and is electrically connected to the X-axis travel assembly 02, the Y-axis travel assembly 03, and the laser rangefinder 05. The analysis and processing device 04, in conjunction with the laser rangefinder 05, is used to measure the width and depth of the groove on the object to be tested. The adsorption assembly 07 includes an adsorption plate 08, an adsorption cover 09, and an air extraction device 10.

The adsorption cover 09 is connected to the lower part of the adsorption plate 08. The adsorption plate 08 is located on the upper surface of the placement plate 06, and the adsorption cover 09 extends downward through the placement plate 06, positioned below it. The connection edge between the adsorption plate 08 and the adsorption cover 09 is sealed using adhesive, sealing rings, or other methods to improve the adsorption effect. The air suction device 10 is connected to the adsorption hood 09 via the adsorption tube 12. When the air suction device 10 is running, the air pressure inside the adsorption hood 09 drops rapidly, forming a uniform negative pressure field on the surface of the adsorption plate 08 through the adsorption holes.
