Description

Technical Field

[0001] This application relates to the field of PCBA board technology, and more specifically, to an external PCBA board for robot 3D vision processing. Background Technology

[0002] The external PCBA board for robot 3D vision processing is an external printed circuit board assembly used for robot 3D vision processing. It provides robots with functions such as image acquisition, processing and analysis, enabling them to perceive and understand three-dimensional space.

[0003] In related technologies, for example, the prior art patent with publication number CN222827524U provides an external PCBA board. When the PCBA board body needs to be disassembled, the positioning pin is pulled outward by the pulling block, so that the positioning pin is separated from the positioning rod, and the restriction on the positioning rod is released. At this time, the buffer spring is reset, pushing the limit block and support column to rise, thereby pushing the support plate to rise, pushing the PCBA board body and the limit cover to move upward, so that the PCBA board body moves outside the mounting base. It is not necessary to disassemble the PCBA board body by external force, thus avoiding damage to the PCBA board body due to external force.

[0004] While the existing technical solutions described above have solved the problem of PCBA board damage caused by removing it with external force, the positioning pins on both sides need to be pulled out to release the restriction on the positioning rod when disassembling the PCBA board. Due to the narrow disassembly environment and complex circuitry of the PCBA board, it is inconvenient to operate when removing the main board and limit cover by pulling out the positioning pins on both sides. This may cause the main board to be bumped, damaging electrical components and affecting the normal use of the main board.

[0005] In view of this, we propose an external PCBA board for robot 3D vision processing. Summary of the Invention

[0010] As an optional solution to the technical solution of this application, the limiting component includes a dovetail groove, which is symmetrically and fixedly disposed on the outside of the fixed outer shell and located below the splicing groove. A dovetail strip is slidably disposed on the inner side of the dovetail groove, and the dovetail strip is fixedly disposed on the bottom of the outer side of the movable outer shell corresponding to the dovetail groove.

[0011] As an optional solution to the technical solution of this application, a positioning groove is provided at the end of the dovetail groove on both sides away from the splicing groove, and a rubber positioning block is slidably provided inside the positioning groove. The rubber positioning block is fixedly provided at the bottom of the dovetail strip, located at the end close to the metal sheet.

[0012] As an optional solution to the technical solution of this application, the chute and the inclined surface of the sliding plate are slidably connected and used to drive the metal sheets on both sides to deform and bend through the bonding plate.

[0018] The present application will be further described in detail below with reference to the accompanying drawings.

[0019] Reference Figure 1 - Figure 6 This application discloses an external PCBA board for robot 3D vision processing, including a PCBA board body 1, a fixed external shell 2, a movable external shell 3, a splicing block 26, and a plug-in block 34. The PCBA board body 1 is driven by an external force to connect and clamp with the fixed external shell 2. The fixed external shell 2 is fixedly disposed on the top of a connecting plate 21, and a rubber edge bracket A22 is fixedly disposed on the inner side of the fixed external shell 2. The movable external shell 3 is slidably disposed on the top of the connecting plate 21, and the PCBA board body 1 is detachably connected inside the movable external shell 3 for driving the PCBA board body 1 to connect with the fixed external shell 26. The shell 2 is connected and clamped for fixation. The outer side of the fixed outer shell 2 is symmetrically provided with splicing grooves 25. A splicing block 26 is fixedly provided inside the splicing groove 25. A plug-in groove 27 is provided inside the splicing block 26. A plug-in block 34 is slidably connected inside the plug-in groove 27. The plug-in block 34 is fixedly provided on the outer side of the movable outer shell 3 corresponding to the splicing groove 25. A limit component is provided between the fixed outer shell 2 and the movable outer shell 3 to guide the splicing of the movable outer shell 3 and the fixed outer shell 2. The splicing block 26 is made of rubber to maintain the stability of the plug-in connection between the fixed outer shell 2 and the movable outer shell 3 during product use.

[0020] During installation, the PCBA board body 1 is first fixedly connected to the robot via the connecting plate 21. Then, the PCBA board body 1 is fixedly connected inside the PCBA board body 1. Next, the movable outer shell 3 is slid towards the fixed outer shell 2 via the limiting component. When the insertion block 34 is inserted into the insertion slot 27, the fixed outer shell 2 and the movable outer shell 3 are fixedly connected. During use, when vibration or shaking occurs, the rubber material of the splicing block 26 absorbs the kinetic energy generated by the vibration or shaking, maintaining the connection between the insertion block 34 and the splicing block 26 and preventing detachment. At the same time, the end of the PCBA board body 1 furthest from the movable outer shell 3 is inserted into the inner side of the rubber fixing frame A22 inside the fixed outer shell 2, limiting the other end of the PCBA board body 1. The system is fixed in place, and the rubber material of the rubber fixing frame A22 protects the other end of the PCBA board body 1. When it is necessary to disassemble the PCBA board body 1, simply grasp the handle at one end of the movable outer shell 3 and pull it outward. After the plug-in block 34 disengages from the splicing block 26, the movable outer shell 3 and the PCBA board body 1 can be taken out together for replacement and maintenance. At the same time, during the process of pulling out the PCBA board body 1, the rubber fixing frame A22 always provides support for the PCBA board body 1, keeping the PCBA board body 1 stable when pulled out. Through the external plug-in fixed connection, the PCBA board body 1 can be quickly installed and removed, which facilitates the disassembly of the PCBA board body 1 from the outside and maintains the operational safety when disassembling the PCBA board body 1.

[0021] Reference Figure 3 , Figure 4 and Figure 5A rubber retaining frame B31 is fixedly installed inside the movable outer shell 3. Metal sheets 35 are symmetrically fixed at the bottom of the rubber retaining frame B31, away from the fixed outer shell 2. Adhesive plates 37 are fixedly installed on the outer sides of both metal sheets 35. Sliding plates 38 are fixedly installed on the outer sides of the adhesive plates 37. A groove 36 is provided on the rubber retaining frame B31 corresponding to the sliding plate 38. The sliding plate 38 is slidably installed inside the groove 36. A tension plate 39 is fixedly installed on the top of the sliding plate 38. A fixing component is provided inside the tension plate 39 to fix the tension plate 39 to the movable outer shell 3. The fixing component includes a insertion slot 301, which extends through the top of the tension plate 39. The inner diameter of 301 is larger than the diameters at both ends. A pin 302 is slidably provided on the inner side of the insertion slot 301. An edge-fitting plate 303 is coaxially fixed on the outer side of the pin 302. The edge-fitting plate 303 is slidably provided on the inner side of the insertion slot 301. A spring 304 is coaxially provided on the outer side of the pin 302, located between the inner side of the insertion slot 301 and the edge-fitting plate 303. The bottom of the pin 302 is slidably provided on the inner side of the fixing groove. The fixing groove is opened on the outer side of the movable outer shell 3. The sliding groove 36 is slidably connected to the inclined surface of the sliding plate 38. It is used to drive the metal sheets 35 on both sides to deform and bend through the bonding plate 37. A rubber sleeve is provided on the bottom of the outer side of the metal sheet 35 to avoid damage to it when fixing the PCBA board body 1.

[0022] When disassembling the PCBA board body 1 from the movable outer shell 3, first manually pull out the pin 302 upwards to compress the spring 304, causing its bottom to disengage from the positioning groove and releasing the fixing effect on the tension plate 39. Then pull the tension plate 39 outwards. At this time, the sliding plate 38 slides upwards at an inclined angle along the sliding groove 36, thereby causing the bottom ends of the metal sheets 35 on both sides to deform and bend upwards through the bonding plate 37, releasing the clamping and fixing effect of the metal sheets 35 on the edges of the PCBA board body 1 placed on the rubber edge bracket B31. Then the PCBA board body 1 can be taken out to complete the disassembly operation. During installation, insert the PCBA board body 1 along the inner side of the rubber edge bracket B31, and then move the outer shell 3. The internal push-pull plate 39 is pushed in, and during the process, the pin 302 is pushed upward due to the height restriction. At the same time, the spring 304 is compressed. When the pin 302 slides into the fixing groove, it is pushed into the fixing groove by the rebound force of the spring 304, thus achieving the positioning and fixing effect of the pull plate 39. At the same time, the pull plate 39 drives the sliding plate 38 to slide downward along the sliding groove 36, and drives the bent metal sheets 35 on both sides to reset through the bonding plate 37, thus achieving the clamping and fixing effect of the PCBA board body 1. At the same time, the rubber sleeve on the metal sheet 35 clamps the edge of the PCBA board body 1, avoiding damage to the PCBA board body 1 caused by clamping and fixing.

[0023] Reference Figure 2 and Figure 3The limiting component includes a dovetail groove 23, which is symmetrically and fixedly disposed on the outside of the fixed outer shell 2, below the splicing groove 25. A dovetail strip 32 is slidably disposed on the inside of the dovetail groove 23. The dovetail strip 32 is fixedly disposed on the bottom outside of the movable outer shell 3 corresponding to the dovetail groove 23. A positioning groove 24 is provided at the end of the dovetail groove 23 away from the splicing groove 25. A rubber positioning block 33 is slidably disposed on the inside of the positioning groove 24. The rubber positioning block 33 is fixedly disposed at the bottom of the dovetail strip 32, at the end close to the metal sheet 35.

[0024] When the movable outer shell 3 and the fixed outer shell 2 are slidably and detachably connected, the dovetail strip 32 is first aligned with the dovetail groove 23 and slid in to restrict the sliding trajectory of the movable outer shell 3 so that the plug-in block 34 can be inserted into the splicing groove 25, thus completing the plug-in block 34 and the splicing block 26. When the fixed outer shell 2 and the movable outer shell 3 are spliced, the rubber positioning block 33 also slides into the positioning groove 24 to restrict and fix the bottom of the other end of the splicing of the fixed outer shell 2 and the movable outer shell 3, ensuring the overall fixing effect of the splicing of the fixed outer shell 2 and the movable outer shell 3.

[0025] In summary, the external PCBA board for robot 3D vision processing disclosed in this application is used in the following ways: First, it is fixedly connected to the robot via the connecting plate 21 during installation. Then, the PCBA board body 1 is fixedly connected inside the PCBA board body 1. Next, the movable outer shell 3 is slid towards the fixed outer shell 2 via the limiting component. When the insertion block 34 is inserted into the insertion slot 27, the fixed outer shell 2 and the movable outer shell 3 are fixedly connected. During use, when vibration or shaking occurs, the rubber material of the splicing block 26 absorbs the kinetic energy generated by the vibration or shaking, maintaining the connection between the insertion block 34 and the splicing block 26 and preventing detachment. Simultaneously, the PCBA board body 1 moves away from the robot. One end of the movable outer shell 3 is inserted into the inner side of the rubber fixing bracket A22 inside the fixed outer shell 2. The rubber fixing bracket A22 restricts and fixes the other end of the PCBA board body 1, and at the same time, the rubber material of the rubber fixing bracket A22 protects the other end of the PCBA board body 1. When it is necessary to disassemble the PCBA board body 1, simply grasp the handle at one end of the movable outer shell 3 and pull it outward. After the insertion block 34 disengages from the splicing block 26, the movable outer shell 3 and the PCBA board body 1 can be taken out together for replacement and repair. At the same time, during the process of pulling out the PCBA board body 1, the rubber fixing bracket A22 always provides support for the PCBA board body 1, maintaining the stability of the PCBA board body 1 when it is pulled out. The external plug-in fixed connection method enables quick installation and removal of the PCBA board body 1, facilitating external disassembly of the PCBA board body 1 and maintaining operational safety during disassembly. When disassembling the PCBA board body 1 from the movable outer shell 3, first manually pull out the pin 302 upwards to compress the spring 304, causing its bottom to disengage from the positioning groove and releasing the fixing effect on the tension plate 39. Then, pull the tension plate 39 outwards. At this time, the sliding plate 38 slides upwards at an inclined angle along the sliding groove 36, thereby causing the bottom ends of the metal sheets 35 on both sides to deform and bend upwards through the bonding plate 37, releasing the clamping effect of the metal sheets 35 on the edges of the PCBA board body 1 placed on the rubber edge bracket B31. After securing the PCBA board body 1, it can be removed to complete the disassembly. During installation, the PCBA board body 1 is inserted along the inner side of the rubber fixing bracket B31. Then, the inner side of the outer shell 3 is moved to push the tension plate 39. During the pushing process, the pin 302 is pushed upward due to height restriction, while the spring 304 is compressed. When the pin 302 slides into the fixing groove, it is pushed into the fixing groove by the rebound force of the spring 304, thus achieving the positioning and fixing effect of the tension plate 39. At the same time, the tension plate 39 drives the sliding plate 38 to slide downward along the sliding groove 36, and through the bonding plate 37, it drives the bent metal sheets 35 on both sides to return to their original position, thus achieving the clamping and fixing effect of the PCBA board body 1 edge.Simultaneously, the rubber sleeve on the metal sheet 35 clamps the edge of the PCBA board body 1, preventing damage to the PCBA board body 1 during clamping and fixing. When the movable outer shell 3 and the fixed outer shell 2 are slidably connected, the dovetail strip 32 is first aligned with the dovetail groove 23 and slid in, restricting the sliding trajectory of the movable outer shell 3 so that the insertion block 34 can be inserted into the splicing groove 25, completing the insertion and fixing of the insertion block 34 and the splicing block 26. When the fixed outer shell 2 and the movable outer shell 3 are spliced, the rubber positioning block 33 also slides into the positioning groove 24, restricting and fixing the bottom of the other end of the spliced ​​fixed outer shell 2 and the movable outer shell 3, ensuring the overall fixing effect of the spliced ​​fixed outer shell 2 and the movable outer shell 3.
