Technical Field
[0001] This utility model relates to the field of screw-locking robot technology, and in particular to a screw-locking robot. Background Technology
[0002] A screw-locking robot is an automated device mainly used to accurately screw screws into designated positions on a workpiece, thus automating the screw assembly process. It typically consists of a robotic arm, a vision system, a screw supply system, and other structures, playing a crucial role in screw tightening.
[0003] Existing screw-locking robots have some shortcomings in use. Traditional screw-locking robots often cause wear on the surface of the screw head after long-term screw-locking operations. When it is necessary to disassemble and maintain the screw head, the operation is relatively difficult. Most of them are fixed with bolts, which puts a burden on the workers and makes it inconvenient to quickly disassemble the screw head for maintenance or replacement. To address the above problems, a screw-locking machine has been proposed for improvement and upgrading. Utility Model Content
[0004] The purpose of this invention is to provide a screw-locking robot to solve the problems mentioned in the background art.
[0005] To solve the above problems, the following technical solution is provided: a screw-locking robot, including a processing table, a positioning structure fixedly disposed on the upper surface of the processing table, and an automatic robotic arm fixedly disposed on one side of the positioning structure. The automatic robotic arm consists of multiple joints, and an mounting plate is fixedly installed on the outer wall of one end of the automatic robotic arm. A screw head is slidably disposed inside the mounting plate, and a disassembly structure is disposed on the upper surface of the mounting plate. The disassembly structure includes two positioning frames fixedly disposed on the upper surface of the mounting plate. A limit plate is fixedly disposed inside each of the two positioning frames. A plug rod is slidably connected inside the limit plate. A limit plate is fixedly disposed on the outer wall of the plug rod, and a buffer spring is fixedly disposed on the outer wall of the limit plate. A display screen is fixedly disposed on the upper surface of the processing table.
[0006] As a preferred embodiment of the above technical solution, the mounting plate has two guide grooves inside, and the screw head has two guide sliders symmetrically arranged at the upper end. The guide sliders are adapted to the size of the guide grooves, and the screw head has two positioning holes symmetrically arranged inside.
[0007] As a preferred embodiment of the above technical solution, one end of the screw head extends through the top of the mounting plate, the two positioning brackets are symmetrical about the screw head, one end of the buffer spring is pressed against the outer wall of the limiting plate, and one end of the plug rod is adapted to the size of the positioning hole.
[0008] As a preferred embodiment of the above technical solution, two limiting protrusions are symmetrically fixedly installed on both sides of the outer wall of the screw head at the bottom of the mounting plate. An electric push rod is fixedly installed inside each of the two limiting protrusions, and an anti-slip clamp is fixedly installed at one end of each electric push rod. The anti-slip clamp fits against the outer wall of the screw head.
[0009] As a preferred embodiment of the above technical solution, the positioning structure includes a conveyor frame fixedly installed on one side of the automated robotic arm. A drive motor is fixedly installed on the outer side of the conveyor frame. A transmission wheel is fixedly installed at the output end of the drive motor, and a threaded screw is fixedly connected to the middle of the transmission wheel. A mounting seat is threadedly connected to the outer wall of the threaded screw, and a placement platform is fixedly installed on the upper end of the mounting seat.
[0010] As a preferred embodiment of the above technical solution, the bottom of the mounting base is fixedly provided with two sets of limiting sliders, and the two sets of limiting sliders are slidably connected inside two guide rails. The two guide rails are fixedly installed inside the conveyor frame. A top plate is fixedly installed on the upper end of the conveyor frame. A protrusion is provided on the upper end of the mounting base, and the protrusion is fixedly connected to the placement platform. The placement platform is located above the top plate.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model device is equipped with components such as a positioning frame, a buffer spring, a plug-in rod, a screw head, and an anti-slip clamp. The anti-slip clamp is separated from the screw head by an electric push rod. Then, the plug-in rod is pulled to cause the limiting plate to squeeze the buffer spring, causing one end of the plug-in rod to be misaligned from the positioning hole. Then, the screw head is pulled out from the mounting plate by a guide slider, which facilitates quick disassembly of the screw head for maintenance or replacement. This avoids the problems of cumbersome and difficult disassembly caused by bolt fixing, reduces the burden on workers, saves time and effort, and is easy to operate.
[0012] 2. The device of this utility model is equipped with components such as a conveyor frame, a drive motor, a placement platform, a mounting base, and a threaded screw. The drive motor drives the mounting base on the threaded screw to move, which in turn causes the placement platform to move slowly and limit the movement of the limit slider on the guide rail. This facilitates the stable movement of the workpiece to the bottom of the robot, making it easier for the robot to perform screw tightening operations.

It should be understood that the embodiments of the present invention are not limited in scope. Within the spirit and scope of the appended claims, the embodiments of the present invention include many changes, modifications, and equivalents. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0017] like Figures 1 to 5 As shown in the figure, this embodiment provides a screw-locking robot, including a processing table 1. A positioning structure 4 is fixedly installed on the upper surface of the processing table 1, and an automatic robotic arm 2 is fixedly installed on one side of the positioning structure 4. The automatic robotic arm 2 consists of multiple joints, and an installation plate 6 is fixedly installed on the outer wall of one end of the automatic robotic arm 2. A screw head 3 is slidably installed inside the installation plate 6, and a disassembly structure 7 is provided on the upper end of the installation plate 6. The disassembly structure 7 includes two positioning frames 71 fixedly installed on the upper end of the installation plate 6. A limit plate 72 is fixedly installed inside each of the two positioning frames 71. A plug rod 73 is slidably connected inside the limit plate 72. A limit plate 75 is fixedly installed on the outer wall of the plug rod 73, and a buffer spring 74 is fixedly installed on the outer wall of the limit plate 75. A display screen 5 is fixedly installed on the upper end of the processing table 1.
[0018] like Figures 3 to 4As shown, the mounting plate 6 has two guide grooves 32 inside, and two guide sliders 31 are symmetrically arranged on the upper end of the screw head 3. The guide sliders 31 are adapted to the size of the guide grooves 32. Two positioning holes 33 are symmetrically arranged inside the screw head 3. One end of the screw head 3 passes through the top of the mounting plate 6. Two positioning brackets 71 are symmetrical about the screw head 3. One end of the buffer spring 74 is pressed against the outer wall of the limiting plate 72. One end of the plug rod 73 is adapted to the size of the positioning hole 33. Two limiting protrusions 61 are symmetrically fixedly installed on both sides of the outer wall of the screw head 3 at the bottom of the mounting plate 6. An electric push rod 62 is fixedly installed inside each of the two limiting protrusions 61, and an anti-slip clamp 63 is fixedly installed at one end of each electric push rod 62. The anti-slip clamp 63 is in contact with the outer wall of the screw head 3.
[0019] By setting two sets of anti-slip clamps 63, the screw head 3 is more stable during installation, and loosening is avoided when tightening the screw. The plug rod 73 slides within the positioning frame 71 and the limiting plate 72, and the plug rod 73 is adapted to the positioning hole 33 on the screw head 3.
[0020] like Figure 5 As shown, the positioning structure 4 includes a conveyor frame 41 fixedly installed on one side of the automatic robotic arm 2. A drive motor 42 is fixedly installed on the outside of the conveyor frame 41. A transmission wheel is fixedly installed at the output end of the drive motor 42, and a threaded screw 43 is fixedly connected to the middle of the transmission wheel. A mounting base 44 is threadedly connected to the outer wall of the threaded screw 43, and a placement platform 45 is fixedly installed on the upper end of the mounting base 44. Two sets of limiting sliders 47 are fixedly installed at the bottom of the mounting base 44, and the two sets of limiting sliders 47 are slidably connected inside two guide rails 46. The two guide rails 46 are fixedly installed inside the conveyor frame 41. A top plate 48 is fixedly installed on the upper end of the conveyor frame 41. A protrusion is provided on the upper end of the mounting base 44, and the protrusion is fixedly connected to the placement platform 45. The placement platform 45 is located above the top plate 48.
[0021] The drive motor 42 drives the transmission wheel to rotate. One end of the conveyor frame 41 is fixedly equipped with a positioning seat. Both transmission wheels are rotatably installed inside the positioning seat, and one end of the threaded screw 43 is also rotatably installed on the positioning seat. The drive motor 42 drives the two transmission wheels to rotate, which in turn drives the threaded screw 43 to rotate. At the same time, after the top plate 48 and the conveyor frame 41 are installed and fixed, there will be gaps on both sides. By extending the protrusions on both sides of the upper end of the mounting seat 44 from the gaps and connecting them to the placement platform 45, it is convenient to support the placement platform 45.
[0022] The working principle and process of this utility model are as follows: First, the operator places the workpiece to be screwed onto the placement table 45. Then, the external power supply is connected, and the drive motor 42 drives the transmission wheel to rotate. This causes the transmission wheel to drive the threaded screw 43 inside the conveyor frame 41 to rotate, thus transporting the workpiece placed on the placement table 45 above the mounting base 44 to the robot for screw installation. Simultaneously, as the mounting base 44 moves, it slides on the guide rail 46 via two sets of limit sliders 47, facilitating stable transport of the workpiece to the robot and enabling the robot to accurately install the screws. This is achieved by driving the movement of multiple joints on the automated robotic arm 2, thereby... The screw head 3 is used to tighten the screw onto the workpiece. Over time, the surface of the screw head 3 is prone to wear. By driving the electric push rod 62 inside the two limiting protrusions 61, the anti-slip clamp 63 is separated from the outer wall of the screw head 3. Then, by pulling the insertion rod 73 inside the two positioning brackets 71, the insertion rod 73 causes the limiting plate 75 to squeeze the buffer spring 74 on the limiting plate 72, causing it to deform. This displaces the insertion rod 73 from the positioning hole 33 on the screw head 3. Then, the screw head 3 slides out of the guide groove 32 using the guide slider 31. The screw head 3 is installed in the reverse manner, which facilitates quick disassembly and assembly of the screw head 3, making it convenient for maintenance or replacement. The operation is convenient.
[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
