Description

A quick-release and fixing device for a robotic arm Technical Field

[0001] This utility model relates to an auxiliary device for disassembling and installing a camera when using a robotic arm for large-scale photography, specifically a quick disassembly and fixing device for a robotic arm. Background Technology

[0002] As people's living standards improve, their cultural lives become increasingly rich, with movies and TV dramas becoming a significant part of their entertainment. However, unlike the micro-videos and short videos on platforms like Douyin and Kuaishou, the filming and recording of these TV dramas, movies, and large-scale events such as speeches, performances, concerts, and galas involve large-scale video production. This includes a large and numerous venue, personnel, and props, rendering traditional handheld cameras obsolete long ago. Currently, robotic arms or robotic cranes are more commonly used for filming, including follow-up shots, large-scale performances, and large-scale film sets. These robotic arms move quickly and smoothly, rotating or swivel, to move cameras or webcams rapidly horizontally, vertically, or vertically, or flip them to capture footage. However, due to the diversity and complexity of current robotic arm filming, cameras frequently need to be replaced. This replacement process is time-consuming, and costs are incurred for space and personnel. Therefore, how to quickly disassemble and install cameras has become a significant concern. In reality, cameras are heavy and must be protected from impacts during disassembly and installation, and they need to be securely fixed, as they move rapidly with the robotic arm and sometimes experience considerable impact. Currently, most cameras require multiple screws to be individually tightened before being fixed to the bottom of the robotic arm, but this time-consuming process results in additional costs due to space and personnel requirements. Summary of the Invention

[0003] The purpose of this utility model is to overcome the technical problems in the prior art and provide a quick-installation and fixing device for robot arms that is relatively simple in structure, small in size, light in weight, easy to operate, takes very little time, can quickly install and disassemble different models of cameras and robot arms, can be firmly fixed, and has a long service life.

[0004] The technical solution of the quick-release fixing device for a robot arm according to this utility model is as follows: it includes a robot arm fixing device, a camera fixing device, and a quick-release device. The robot arm fixing device is detachably and fixedly connected to the end of the robot arm, and the camera fixing device is detachably and fixedly connected to the camera. The robot arm fixing device and the camera fixing device are quickly and releasably fixedly connected through the quick-release device.

[0005] The quick-release and fixing device for a robot arm according to this utility model can also be:

[0006] The quick-release device includes a robotic arm fixing block and a camera fixing post. The robotic arm fixing block is fixed to or integrally formed on the top of the robotic arm fixing device, and the camera fixing post extends to the bottom of the camera fixing device. The robotic arm fixing block has an arm fixing hole, and the camera fixing post is quickly and releasably fixed to the arm fixing hole.

[0007] The robotic arm fixing block is equipped with a limiting type of reciprocating fixing block. The reciprocating movement of the fixing block can release and fix it to the camera fixing post, and the camera fixing post can be detachably fixed in the arm fixing hole.

[0008] The fixing block is driven by a fixing driver to retract and fix itself to the camera fixing post.

[0009] The fixed driver is a helical-forward operating wrench connected inside the fixed block of the robotic arm. The rear end of the operating wrench can be disengaged from the fixed block and pushes the fixed block to move toward the far end and abut against the camera fixing post.

[0010] The robotic arm fixing block is provided with at least two arm fixing holes. The bottom of the camera fixing device is provided with a corresponding number of arm fixing posts at the positions corresponding to the arm fixing holes. The fixing block is driven by the operating wrench to releasably abut against the camera fixing posts and releasably fix the camera fixing posts in the arm fixing holes.

[0011] The robotic arm fixing block is provided with four arm fixing holes, which are located at the four corners of the quadrilateral. The rear end of the operating wrench abuts against an active operating lever. The left and right ends of the active operating lever are respectively releasably inclined against one end of two driven operating levers. The other end of the driven operating lever is respectively releasably inclined against one end of two adjacent fixing blocks, pushing the fixing blocks forward or backward. The other end of the fixing blocks is respectively releasably abutted against and fixed to the corresponding camera fixing posts.

[0012] The end cross-section of the active operating lever is pointed, and the left and right ends of the two driven operating levers and the front and rear ends of the four fixing blocks are also pointed. The end of the active operating lever is inclined and slidably connected to the right and left ends of the two driven operating levers, respectively. The pointed corners of the front or rear ends of the driven operating levers are releasably abutted and fixed to the camera fixing post.

[0013] The camera mounting post is provided with a fixing groove, and the fixing block can be detachably engaged with the fixing groove to detachably fix the camera mounting post in the arm fixing hole.

[0014] The fixed driver has an external thread at its rear end, and the robotic arm fixing block has an internal thread at its front opening. The fixed driver and the robotic arm fixing block are connected by a threaded rotary push-in connection. The head end of the fixed driver has a wrench fixing groove for engaging with an external wrench handle.

The robotic arm fastening device is detachably and fixedly connected to the end effector of the robotic arm, and the camera fastening device is detachably and fixedly connected to a camera. The robotic arm fastening device and the camera fastening device are quickly and releasably fastened together via the quick-release device. Thus, during use, the robotic arm fastening device is pre-detachably and fixed to the end effector of the robotic arm, and the camera fastening device and camera are pre-installed, eliminating the need for time-consuming on-site fastening and reinstallation after camera replacement. When camera replacement is required on-site, the camera fastening device, already fixed to the camera, can be quickly and directly installed onto the robotic arm fastening device via the quick-release device, allowing for rapid installation of the required signal and format camera onto the end effector of the robotic arm in approximately 10 seconds. When replacement is needed, the quick-release device can be removed within 10 seconds, allowing the camera mounting device to quickly detach from the robotic arm mounting device. Then, the camera mounting device with the removed camera is detached, and the required camera, along with its detachably fixed mounting device, is quickly installed onto the robotic arm mounting device using the quick-release device. This process takes approximately half a minute to one minute to remove the unwanted camera, and then the required camera is quickly installed onto the end of the robotic arm for continued shooting and recording. The camera mounting device and the camera are detachably connected by camera mounting bolts, with camera mounting screw holes corresponding to the camera mounting screw holes. The robotic arm mounting device and the end of the robotic arm are detachably connected by arm mounting bolts, with arm mounting screw holes on the edge of the robotic arm mounting device and corresponding positions on the end of the robotic arm. The arm mounting bolts are threaded into the arm mounting screw holes on both the robotic arm mounting device and the end of the robotic arm, detachably securing them together. Of course, the detachable fixing connection between the camera fixing device and the camera, as well as between the robotic arm fixing device and the end effector of the robotic arm, can adopt other conventional methods, as long as they can be detachably fixed together in pairs. Therefore, the quick-release device can complete the rapid disassembly and installation of the camera and the end effector of the robotic arm, saving time and costs. Moreover, it has a simple structure, and because of its simple structure and firm fixing, it has a relatively long service life.Therefore, the advantages of this utility model for a quick assembly and disassembly fixing device for a robot arm compared to the prior art are: relatively simple structure, small size, light weight, easy operation, quick and secure installation and disassembly of different models of cameras and robot arms in a short time, and long service life.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0027] This utility model discloses a quick-release and fixing device for a robotic arm, as shown in Figures 1 to 5. It includes a robotic arm fixing device 1, a camera fixing device 2, and a quick-release device. The robotic arm fixing device 1 is detachably and fixedly connected to the end effector of the robotic arm, and the camera fixing device 2 is detachably and fixedly connected to a camera. The robotic arm fixing device 1 and the camera fixing device 2 are quickly and releasably fixed together via the quick-release device. Thus, during use, the robotic arm fixing device 1 is pre-detachably fixed to the end effector of the robotic arm, and the camera fixing device 2 and the camera are pre-installed, eliminating the need for time-consuming on-site fixing and reinstallation of the camera onto the robotic arm fixing device 1 after camera replacement. When camera replacement is required on-site, the camera fixing device 2, already fixed to the camera, can be quickly and directly installed onto the robotic arm fixing device 1 via the quick-release device, allowing for rapid installation of the required signal and format camera onto the end effector of the robotic arm in approximately 10 seconds. When replacement is needed, the quick-release device can be removed within 10 seconds, allowing the camera mounting device 2 to quickly detach from the robotic arm mounting device 1. Then, the camera mounting device 2, along with the removed camera, is detached. The desired camera, along with its detachably fixed mounting device 2, is then quickly installed onto the robotic arm mounting device 1 using the quick-release device. This process takes approximately half a minute to one minute to remove the unwanted camera, and then the desired camera is quickly installed onto the end of the robotic arm for continued shooting and recording. The camera mounting device 2 and the camera are detachably connected by camera mounting bolts. The camera mounting device 2 has camera mounting screw holes corresponding to the camera mounting screw holes. The robotic arm mounting device 1 is detachably connected to the end of the robotic arm by arm mounting bolts. The edge of the robotic arm mounting device 1 has arm mounting screw holes, and corresponding arm mounting screw holes are also provided at the end of the robotic arm. The arm fixing bolts are sequentially threaded into the arm fixing screw holes of the robotic arm fixing device 1 and the end of the robot arm, detachably and securely connecting the robotic arm fixing device 1 and the end of the robot arm together. Of course, other conventional methods can be used to detachably and securely connect the camera fixing device 2 and the camera, as well as the robotic arm fixing device 1 and the end of the robot arm, as long as they can be detachably and securely connected in pairs. Therefore, the quick-release device can quickly detach and install the camera and the end of the robot arm, saving time and costs. Furthermore, its simple structure and strong fixation result in a long service life.Therefore, the advantages of this utility model for a quick assembly and disassembly fixing device for a robot arm compared to the prior art are: relatively simple structure, small size, light weight, easy operation, quick and secure installation and disassembly of different models of cameras and robot arms in a short time, and long service life.

[0028] This utility model discloses a quick-release and fastening device for a robotic arm. Referring to Figures 1 to 5, based on the preceding technical solution, the quick-release device specifically includes a robotic arm fixing block 3 and a camera fixing post 4. The robotic arm fixing block 3 is fixed to or integrally formed on the top of the robotic arm fixing device 1. The camera fixing post 4 extends to the bottom of the camera fixing device 2. The robotic arm fixing block 3 has an arm fixing hole 5, and the camera fixing post 4 is quickly and releasably fixed within the arm fixing hole 5. Thus, when installation is required, the robotic arm fixing device 1 is fixed to or integrally formed with the robotic arm fixing block 3. The bottom of the camera fixing device 2 has the downward-extending camera fixing post 4, and the robotic arm fixing block 3 has a corresponding arm fixing hole 5. During installation, the camera fixing post 4 is inserted downward into the arm fixing hole 5, and then fixed within the arm fixing hole 5, completing the quick installation between the robotic arm fixing device 1 and the camera fixing device 2. Correspondingly, when disassembly is required, the locking connection between the arm fixing hole 5 and the camera fixing post 4 is released, and then the camera fixing post 4 is pulled out from the arm fixing hole 5. This allows the robotic arm fixing device 1 and the camera fixing device 2 to be separated, and the camera can be detached from the end of the robotic arm. Of course, other specified methods or other quick-release devices can also be used, as long as they can quickly disassemble and install the camera fixing device 2 and the robotic arm fixing device 1. A further preferred technical solution of this utility model for a quick-release fixing device for a robotic arm, based on the preceding technical solution, is as follows: a limiting, reciprocating fixing block 6 is provided inside the robotic arm fixing block 3. The fixing block 6 reciprocates and abuts against the camera fixing post 4, detachably fixing the camera fixing post 4 within the arm fixing hole 5. During installation, the fixing block 6 moves toward the camera fixing post 4, so that its front end abuts against the camera fixing post 4, pushing the camera fixing post 4 in one direction and pressing it tightly against the arm fixing hole 5 where it is located. The fixing block 6 moves further, thereby pressing the camera fixing post 4 tightly against the inner wall of the arm fixing hole 5, thus firmly fixing the camera fixing post 4 to the robotic arm fixing block 3, and finally firmly fixing it together with the robotic arm fixing device 1.Alternatively, during disassembly, the fixing block 6 moves away from the camera fixing post 4, causing its front end to disengage from the connection with the camera fixing post 4. This moves the camera fixing post 4 away from the inner wall of the arm fixing hole 5, and the fixing block 6 moves further away, thus moving the camera fixing post 4 away from the inner wall of the arm fixing hole 5. This releases the camera fixing post 4 from the robot arm fixing block 3, ultimately separating the camera fixing device 2 from the robot arm fixing device 1, and thus detaching the camera from the end of the robot arm. A further preferred technical solution of this invention's quick-release and fixing device for a robot arm can be: the fixing block 6 is driven by a fixing driver to retract and move in a detachable manner against the camera fixing post 4. The driver drives the fixing block 6 to move away from or closer to the corresponding camera fixing post 4, realizing the quick disassembly and installation of the camera fixing device 2 and the robot arm fixing device 1, thereby realizing the quick disassembly and installation of the camera and the end of the robot arm. A further preferred embodiment of the quick-release and fixing device for a robotic arm, based on the preceding technical solution, is as follows: the fixing driver is a helical wrench 7 connected internally to the fixing block 3 of the robotic arm. The rear end of the wrench 7 is releasably abutted against the fixing block 6, pushing the fixing block 6 towards the distal end and abutting against the camera fixing post 4. When the wrench 7 is rotated clockwise or counterclockwise, its helical movement propels it towards or away from the fixing block 6, thereby causing the fixing block 6 to move towards or away from the camera fixing post 4. The fixing block 6 then fixes the camera fixing post 4 within the arm fixing hole 5 or releases the fixation between the camera fixing post 4 and the arm fixing hole 5, thereby allowing the camera to be installed together with or detached from the end of the robotic arm.

[0029] This utility model discloses a quick-release and fixing device for a robotic arm. Referring to Figures 1 to 5, a further preferred technical solution based on the preceding technical solution is as follows: The robotic arm fixing block 3 is provided with at least two arm fixing holes 5. The bottom of the camera fixing device 2 is provided with a corresponding number of arm fixing posts at positions corresponding to the arm fixing holes 5. The fixing block 6 is driven by the operating wrench 7 to releasably abut and fix to the camera fixing posts 4, and the camera fixing posts 4 are releasably fixed within the arm fixing holes 5. Thus, by providing two or more arm fixing holes 5 and corresponding camera fixing posts 4, the fixing is more secure, preventing the camera from falling and breaking during movement after installation. The installation and disassembly methods are the same as described above and will not be repeated here. A further preferred embodiment of the quick-release and fixing device for a robot arm according to this utility model, based on the preceding technical solution, is as follows: The robot arm fixing block 3 is provided with four arm fixing holes 5, located at the four corners of a quadrilateral. The rear end of the operating wrench 7 abuts against an active operating lever 8. The left and right sides of the end of the active operating lever 8 are respectively releasably inclined against one end of two driven operating levers 9. The other ends of the driven operating levers 9 are respectively releasably inclined against one end of two adjacent fixing blocks 6, pushing the fixing blocks 6 forward or backward. The other ends of the fixing blocks 6 are respectively releasably abutted against and fixed to the corresponding camera fixing posts 4. This further configuration of four camera fixing posts 4 and four corresponding arm fixing holes 5, with camera fixing posts 4 fixed within the arm fixing holes 5 at each of the four corners of the quadrilateral, results in a more secure and stable fixation, accurate alignment during fixing, and prevention of shaking. The optimal technical solution is to position the four camera mounting posts 4 at the four corners of a square or rectangle. This arrangement facilitates manufacturing, ensures even force distribution, avoids stress concentration, effectively extends the service life of the entire quick-release device, and reduces costs. Another advantage of this arrangement is that by using the operating wrench 7 to move one of the active operating levers 8, which in turn moves two driven operating levers 9 back and forth, thereby causing the four fixing blocks 6 to move back and forth. This allows the camera mounting posts 4 to be abutted and fixed within the arm fixing holes 5, or the camera mounting posts 4 to be released from the arm fixing holes 5 and removed. This enables the camera fixed to the camera mounting device 2 and the end effector of the robot arm fixed to the robot arm fixing block 3 to be installed together or disassembled.A further preferred embodiment of the quick-release and fixing device for a robot arm according to this utility model, based on the preceding technical solution, is as follows: the end cross-section of the active operating lever 8 is pointed, the left and right ends of the two driven operating levers 9 and the front and rear ends of the four fixing blocks 6 are also pointed. The end of the active operating lever 8 is inclined and slidably connected to the right and left ends of the two driven operating levers 9, respectively. The pointed corners of the front or rear ends of the driven operating levers 9 are releasably abutted and fixed to the camera fixing post 4. This arrangement allows the active operating lever 8, the driven operating levers 9, and the fixing blocks 6 to move forward or backward by means of the force exerted when their pointed corners abut against each other. Specifically, the front end of the active operating lever 8 has a pointed cross-section. The front end of the active operating lever 8 has two first main planes that gradually slope backward from the center of the tip to the left and right sides. These two first main planes abut against the second planes of the ends of the driven operating levers 9, located on either side of the active operating lever 8, which slope backward from the center of the tip. Because of the two inclined planes, when the active operating lever 8 is pushed backward, the first main planes abut and press against the second planes, causing the second planes of the driven operating levers 9 located on the left and right sides of the active operating lever 8 to slide on the first main planes. This results in the driven operating levers 9 being pushed to the left and right respectively. The tips of the ends of the active operating levers 8, which move to the left and right respectively, have a similar position and function to the previously described second planes (a mirror image of the inclined planes) in a third... The planes move to the left and right respectively, and the front end of the fixing block 6, which is corresponding to the end of the driven operating lever 9, is inclined to the left and right and backward from the center of the tip. The four third planes are inclined and abut against the two second planes respectively. When the driven operating lever 9 moves to the left and right respectively, it pushes the fixing block 6 located on the front and rear sides of the end of the driven operating lever 9 to move forward and backward respectively, thereby pushing the camera fixing post 4 located at the front and rear ends of the corresponding fixing block 6 forward or backward, thereby pushing the camera fixing post 4 against the inner wall of the arm fixing hole 5, and fixing the four camera fixing posts 4 in the corresponding four arm fixing holes 5, so as to realize the firm and quick fixation of the camera and the end of the robot arm. Only one operating wrench 7 is needed to achieve fixation in four positions.

[0030] This utility model discloses a quick-release and fixing device for a robotic arm. Referring to Figures 1 to 5, based on the preceding technical solution, it can also be configured such that: a fixing groove 10 is provided around the camera fixing post 4; the fixing block 6 can be detachably engaged with the fixing groove 10 to detachably fix the camera fixing post 4 into the arm fixing hole 5. In this way, the front end of the fixing block 6 detachably engages with the fixing groove 10 to push and fix the camera fixing post 4 into the arm fixing hole 5. This reduces the overall weight of the components while improving the fixing effect.

[0031] A further preferred embodiment of the quick-release and fixing device for a robot arm according to this utility model, based on the preceding technical solution, is as follows: the rear end of the fixing driver is provided with an external thread, and the front opening of the robot arm fixing block 3 is provided with an internal thread. The fixing driver and the robot arm fixing block 3 are connected by a threaded rotary push-in connection. The head end of the fixing driver is provided with a wrench fixing groove 11 for engaging with an external wrench handle. In this way, the end of the external wrench handle is inserted into the wrench fixing groove 11. The wrench fixing groove 11 is provided with a hexagonal or pentagonal notch, so that the end of the external wrench handle is locked in the notch. Thus, when the external wrench handle is shaken externally, it can drive the entire fixing driver to spiral forward or backward. The fixing driver then drives the fixing block 6 to move back and forth to achieve the fixing and contact fixation of the camera fixing post 4 and the arm fixing hole 5.

They are only for the convenience of describing this utility model 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.
