Technical Field
[0001] This utility model belongs to the field of visual inspection technology, specifically relating to a positioning device based on lidar and a camera. Background Technology
[0002] Vision module positioning devices are mechanisms used in various fields to correct the position of materials or to detect defects. They can detect deviations in various directions when materials are fed, compare the materials with a set position, or identify defects that appear on the surface of materials during the production process. Commonly used vision modules include cameras and lidar, which are often used together to improve the accuracy of visual inspection.
[0003] Existing positioning devices are inconvenient for installing and disassembling vision modules, with complex connection methods, low assembly and disassembly efficiency, and impact on production rhythm. Furthermore, existing positioning devices lack external lighting devices, making them difficult to use in situations with insufficient lighting. Therefore, we propose a positioning device based on LiDAR and a camera. Utility Model Content
[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a positioning device based on lidar and camera, so as to solve the problems mentioned in the background art that the existing positioning devices are not convenient for installing and disassembling vision modules, have complicated connection methods, low disassembly and assembly efficiency, affect production rhythm, and the existing positioning devices do not have external lighting devices, making them difficult to use in insufficient lighting conditions.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning device based on lidar and a camera, comprising a detection machine, a top plate fixedly connected to the surface of the detection machine, a detection platform fixedly connected to the top of the top plate, a control panel fixedly connected to the surface of the detection machine, a fixing frame fixedly connected to the top of the top plate, an adjustment structure provided on the surface of the fixing frame, the adjustment structure comprising a fixing block, a fixing plate fixedly connected to the bottom of the fixing block, two sets of mounting blocks mounted on the surface of the fixing plate, a rotating seat rotatably connected inside the mounting block, and an anti-slip sleeve fixedly connected inside the mounting block. Two sets of gooseneck tubes are fixedly connected to the bottom of the rotating base. A light is fixedly connected to the bottom of each gooseneck tube. A quick-release structure is provided on the top of the mounting frame. The quick-release structure includes a mounting plate. A connecting rod is fixedly connected to the surface of the mounting plate. A fixed seat is fixedly connected to the bottom of the connecting rod. Sliding grooves are provided on both sides of the fixed seat. A slider is slidably connected inside the sliding groove. Two sets of springs are fixedly connected to the bottom of the slider. Two sets of insert rods are fixedly connected to the top of the slider. Pull plates are fixedly connected to the front and rear ends of the slider. Connecting blocks are slidably connected to both sides of the fixed seat. A vision module is fixedly connected to the surface of the connecting blocks.
[0006] Preferably, the vision module is a lidar or a camera, and both the vision module and the lighting lamp are electrically connected to the control panel, which is electrically connected to an external power supply.
[0007] Preferably, the fixing block is fixedly connected to the surface of the fixing frame by bolts, and the surface of the fixing plate is provided with an adjustment groove. The mounting block is installed on the surface of the fixing plate by the cooperation of the bolts and the adjustment groove.
[0008] Preferably, the surface of the mounting block has a circular groove, the anti-slip sleeve is fixedly connected in the circular groove, one side of the rotating seat is rotatably connected in the circular groove, and the anti-slip sleeve is made of rubber.
[0009] Preferably, the mounting plate is fixedly connected to the surface of the mounting bracket by bolts.
[0010] Preferably, the two sets of pull plates pass through the inner walls of the front and rear ends of the slide groove and are fixedly connected to the slider, and the two ends of the spring are fixedly connected to the bottom of the slider and the bottom of the inner wall of the slide groove, respectively.
[0011] Preferably, the connecting block is C-shaped and is slidably connected to both sides of the fixed base. The top of the connecting block has two sets of circular grooves, and the insert rod passes through the top of the groove and is inserted into the circular groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This positioning device based on LiDAR and camera features a quick-release structure. Pressing the pull plate causes the slider to slide downwards within the groove. The downward movement of the slider compresses the spring, causing the insert rod at the top of the slider to move downwards and completely detach from the circular groove at the top of the connecting block. After detachment, the connecting block and the vision module can be slid out from both sides of the fixed base, completing the disassembly. The entire process requires no tools and can be operated with one hand. Simply pulling / releasing the pull plate completes the disassembly and assembly of the vision module. No tools are needed, making the operation simple and fast, greatly reducing equipment downtime for maintenance and improving production efficiency.
[0013] 2. This positioning device based on lidar and camera features an adjustment structure. The rotating seat can rotate around a circular groove, and with the flexible bending (multi-directional angle) of the gooseneck tube, the lighting lamp can be precisely adjusted at any angle and position within three-dimensional space. This ensures that the light is accurately projected onto the observation area of the vision module, especially providing necessary illumination on complex surfaces or in dark areas. The rubber anti-slip sleeve tightly fits the rotating seat's axis, providing sufficient frictional resistance to ensure that the rotating seat can be reliably fixed after being adjusted to the required position. This prevents the lighting lamp angle from shifting due to vibration or contact during operation. By setting a long strip adjustment groove on the surface of the fixed plate, the mounting block can slide along the length of the groove and be fixed with bolts, thereby adjusting the relative distance between the two lighting lamps to adapt to the lighting needs of different sizes or areas.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-5 One embodiment provided by this utility model: A positioning device based on lidar and a camera includes a detection machine 1. A top plate 11 is fixedly connected to the surface of the detection machine 1. A detection platform 12 is fixedly connected to the top of the top plate 11. A control panel 13 is fixedly connected to the surface of the detection machine 1. A fixing frame 14 is fixedly connected to the top of the top plate 11. An adjustment structure 2 is provided on the surface of the fixing frame 14. The adjustment structure 2 includes a fixing block 21. A fixing plate 22 is fixedly connected to the bottom of the fixing block 21. Two sets of mounting blocks 23 are mounted on the surface of the fixing plate 22. A rotating seat 24 is rotatably connected inside the mounting block 23. An anti-slip sleeve 25 is fixedly connected inside the mounting block 23. Two sets of gooseneck tubes 26 are fixedly connected to the bottom of the rotating seat 24. A light 27 is fixedly connected to the bottom. A quick-release structure 3 is provided on the top of the mounting bracket 14. The quick-release structure 3 includes a mounting plate 31. A connecting rod 32 is fixedly connected to the surface of the mounting plate 31. A mounting base 33 is fixedly connected to the bottom of the connecting rod 32. Slide grooves 34 are provided on both sides of the mounting base 33. A slider 35 is slidably connected inside the slide grooves 34. Two sets of springs 36 are fixedly connected to the bottom of the slider 35. Two sets of insert rods 37 are fixedly connected to the top of the slider 35. Pull plates 38 are fixedly connected to the front and rear ends of the slider 35. Connecting blocks 39 are slidably connected to both sides of the mounting base 33. A vision module 310 is fixedly connected to the surface of the connecting block 39. The quick-release structure 3 is provided. Pressing the pull plate 38 will pull the plate 38. The slider 35 slides downward within the groove 34, compressing the spring 36. The insert rod 37 at the top of the slider 35 moves downward accordingly, completely disengaging from the circular groove 2 at the top of the connecting block 39. After disengagement, the connecting block 39, along with the vision module 310, can slide out from both sides of the fixed base 33, completing the disassembly. The entire process requires no tools and can be operated with one hand. Simply pulling / releasing the pull plate 38 completes the disassembly and assembly of the vision module 310. No tools are needed; the operation is simple and quick, greatly reducing equipment downtime for maintenance and improving production efficiency. An adjustment structure 2 is provided, allowing the rotating base 24 to rotate around the circular groove 1. Combined with the flexible bending of the gooseneck tube 26 at multiple angles, this allows... The lighting lamp 27 can be finely adjusted at any angle and position within a three-dimensional space, ensuring that the light is accurately projected onto the observation area of the vision module 310, especially providing necessary illumination on complex surfaces or dark areas. The rubber anti-slip sleeve 25 fits tightly against the rotating shaft of the rotating seat 24, providing sufficient frictional resistance to ensure that the rotating seat 24 can be reliably fixed after being adjusted to the required position, preventing the lighting lamp 27 from shifting due to vibration or contact during operation. By setting a long strip adjustment groove on the surface of the fixing plate 22, the mounting block 23 can slide along the length of the groove and be fixed by bolts, thereby realizing the adjustment of the relative distance between the two lighting lamps 27 to adapt to the lighting needs of different sizes or areas.
[0018] Furthermore, the vision module 310 is either a lidar or a camera. Both lidar and cameras are common devices in visual inspection, and there are no specific requirements for their models. Both are existing technologies. The vision module 310 and the lighting lamp 27 are electrically connected to the control panel 13. The control panel 13 is electrically connected to an external power supply and is powered by the external power supply. The control panel 13 controls the vision module 310 and the lighting lamp 27.
[0019] Furthermore, the fixing block 21 is fixedly connected to the surface of the fixing frame 14 by bolts, and the surface of the fixing plate 22 is provided with an adjustment groove. The mounting block 23 is installed on the surface of the fixing plate 22 by the cooperation of bolts and the adjustment groove. The adjustment groove is elongated, and the mounting block 23 can slide in the length direction of the groove and be fixed by bolts, thereby realizing the adjustment of the relative distance between the two lighting lamps 27.
[0020] Furthermore, a circular groove is provided on the surface of the mounting block 23, and the anti-slip sleeve 25 is fixedly connected in the circular groove. One side of the rotating seat 24 is rotatably connected in the circular groove. The anti-slip sleeve 25 is made of rubber. The rubber anti-slip sleeve 25 fits tightly against the rotating shaft of the rotating seat 24, providing sufficient frictional resistance to ensure that the rotating seat 24 can be reliably fixed after being adjusted to the required position.
[0021] Furthermore, the mounting plate 31 is fixedly connected to the surface of the mounting bracket 14 by bolts, which facilitates the installation and disassembly of the quick-release structure 3 as a whole.
[0022] Furthermore, two sets of pull plates 38 are respectively connected to the slider 35 through the inner walls of the front and rear ends of the slide groove 34. The two ends of the spring 36 are respectively connected to the bottom of the slider 35 and the bottom of the inner wall of the slide groove 34. When the pull plate 38 is pressed, the pull plate 38 drives the slider 35 to slide downward in the slide groove 34. The slider 35 moves downward to compress the spring 36, and the rod 37 at the top of the slider 35 moves downward accordingly.
[0023] Furthermore, the connecting block 39 is C-shaped and is slidably connected to both sides of the fixed base 33. The top of the connecting block 39 has two sets of circular grooves. The insert rod 37 passes through the top of the sliding groove 34 and is inserted into the circular groove. When the insert rod 37 is inserted into the circular groove, the two engage with each other, fixing the connecting block 39 and the fixed base 33 together. The connecting block 39 is designed as a C-shaped structure so that it can reliably hold the corresponding part of the fixed base 33. With the insert rod 37 inserted into the circular groove, the stability and vibration resistance of the vision module 310 in the horizontal and vertical directions are ensured after installation.
[0024] Working principle: When the vision module 310 needs to be replaced or maintained, press the pull plate 38. The pull plate 38 drives the slider 35 to slide downward in the slide groove 34. The downward movement of the slider 35 compresses the spring 36. The insertion rod 37 fixed on the top of the slider 35 moves downward accordingly and completely disengages from the circular groove 2 on the top of the connecting block 39. After disengagement, the connecting block 39 and the vision module 310 can be slid downward or in a specific direction (such as vertically downward) from both sides of the fixing seat 33 to complete the disassembly. The whole process does not require tools and can be operated with one hand. Align the connecting block 39 with the slide groove 34 on both sides of the fixing seat 33 and slide it into place. Release the pull plate 38. The compressed spring 36 pushes the slider 35 upward to reset. 5. The insertion rod 37 is inserted upward into the second circular groove on the top of the connecting block 39, so as to quickly and firmly lock the connecting block 39 and the fixed seat 33. The rotating seat 24 can rotate around the first circular groove. With the flexible bending (multi-directional angle) of the gooseneck tube 26, the lighting lamp 27 can be finely adjusted at any angle and position in three-dimensional space, ensuring that the light is accurately projected onto the observation area of the vision module 310, especially providing necessary illumination on complex surfaces or dark areas. The rubber anti-slip sleeve 25 fits tightly against the rotating shaft of the rotating seat 24, providing sufficient frictional resistance to ensure that the rotating seat 24 can be reliably fixed after being adjusted to the required position, preventing the lighting lamp 27 from shifting due to vibration or contact during operation.
