Description

Technical Field

[0001] The invention relates to the technical field of laser displacement sensor distance measurement, and in particular to a laser displacement sensor distance measurement device. Background Art

[0002] Laser displacement sensors mainly use the principle of laser triangulation measurement to calculate the change in distance between the object and the sensor by measuring the change in angle of the laser beam from emission to reflection by the object. This sensor can achieve high-precision non-contact measurement and is often used to detect geometric quantities such as displacement, flatness, thickness, vibration, distance, and diameter of objects. The advantages of laser displacement sensors include non-contact measurement, long-distance measurement, measurement of tiny objects, high-speed and high-precision measurement, and the ability to measure most objects.

[0003] When the laser displacement sensor is used for automated grasping, it assists the precise positioning of the robotic arm. The grasping robotic arm needs to move up and down with the laser displacement sensor when measuring distance, in order to measure multiple points or continuous areas and obtain more comprehensive data. When measuring distance, it is necessary to avoid obstruction, so the connecting wire on one side of the laser displacement sensor needs to be located at the top of the robotic arm to prevent the wire from affecting the grasping work of the robotic arm and the measurement work of the laser displacement sensor. However, the cables on one side of most existing related laser displacement sensors are directly wound around and hung on the robotic arm. This method causes the robotic arm to pull the connecting wire when it moves, and the connection between the laser displacement sensor and the connecting wire may bend, deform, or even break. Therefore, the present application provides a laser displacement sensor distance measurement device to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a laser displacement sensor ranging device. By setting up an installation mechanism, the laser displacement sensor body can assist the mechanical arm body in precise positioning to ensure the accuracy of the mechanical arm body picking up. The connecting wire body is located at the top of the mechanical arm body, and the connection between the laser displacement sensor body and the connecting wire body is protected by the installation mechanism. The laser displacement sensor body can be quickly and stably installed on the mechanical arm body for use by using the installation mechanism, which effectively increases the work efficiency of the installation of the laser displacement sensor body. The use of the installation mechanism can also effectively prevent the problem of excessive bending of the connection between the connecting wire body and the laser displacement sensor body during use. The above setting can solve the problem of bending, deformation or even breakage at the connection of the connecting wire.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A laser displacement sensor distance measuring device comprises a mechanical arm body, a gripping mechanism is provided at one end of one side of the mechanical arm body, a laser displacement sensor body is mounted on the gripping mechanism, a connecting wire body is fixedly connected to the top of the laser displacement sensor body, a conveyor belt body is mounted on one side of the mechanical arm body, a gripping piece is provided at the top of the conveyor belt body; an installation mechanism, the installation mechanism is used to install and fix the laser displacement sensor body on the gripping mechanism in the mechanical arm body, and the installation mechanism is connected to the laser displacement sensor body.

[0007] Optionally, the mounting mechanism includes a mounting frame, a protective frame is fixedly connected to the top of the mounting frame, a first clamp is fixedly connected to the end of the mounting frame on one side away from the laser displacement sensor body, a second clamp is fixedly connected to the end of the protective frame on one side away from the laser displacement sensor body, a cable tie body is fixedly connected to the protective frame, and a mounting block is fixedly connected to the side of the mounting frame close to the laser displacement sensor body.

[0008] Optionally, reinforcing ribs are provided in the mounting frame, and the mounting frame, the protective frame, the first clamping block and the second clamping block are integrally constructed.

[0009] Optionally, the cross-section of the first clamping block is C-shaped, and a first guide portion is provided at an end portion of one side of the first clamping block away from the mounting frame.

[0010] Optionally, the protective frame is an arc-shaped structure, and a first lightweight groove is provided on the protective frame.

[0011] Optionally, the cross section of the second clamping block is square, and a second guide portion is provided at an end portion of one side of the second clamping block away from the protective frame.

[0014] Optionally, the limiting plate is made of rubber material, and a third guide portion is provided at an end portion of the limiting plate away from the protective frame.

[0015] Optionally, two reinforcing sheets are disposed opposite to each other on the inner wall of one side of the mounting block close to the laser displacement sensor body, a weakened portion is formed on the reinforcing sheet, and second lightweight grooves are formed at equal intervals on the mounting block.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting up the installation mechanism, the laser displacement sensor body can assist the mechanical arm body in precise positioning to ensure the accuracy of the mechanical arm body picking up. The connecting wire body is located at the top of the mechanical arm body, and the connection between the laser displacement sensor body and the connecting wire body is protected by the installation mechanism. The laser displacement sensor body can be quickly and stably installed on the mechanical arm body for use by using the installation mechanism, which effectively increases the work efficiency of the installation of the laser displacement sensor body. The use of the installation mechanism can also effectively prevent the problem of excessive bending of the connection between the connecting wire body and the laser displacement sensor body during use, thereby ensuring the normal use of the laser displacement sensor body and preventing the connecting wire body from falling to the bottom of the mechanical arm body to cause line of sight obstruction. The specific use of the installation mechanism is described in detail below, and the structure of the device is simple and the production cost is low.

[0018] By providing a first clamping block and a mounting block in the mounting mechanism, a mounting groove compatible with the mounting block can be opened near the grasping part of the robot arm body. Through the coordinated use of the first clamping block and the mounting block, the laser displacement sensor body can be quickly and stably installed on the robot arm body for use, so as to ensure the accuracy of the grasping work of the robot arm body. The structure further makes the use effect of the mounting mechanism better.

[0019] By providing a protective frame and a cable tie body in the installation mechanism, the protective frame and the cable tie body are used in coordination to fix the curved connecting wire body between the two groups of cable tie bodies, so that the protective frame is first pulled when the robot arm body moves, and the deformation range of the protective frame is limited. When it is stretched to a straight line, it stops deforming. In this process, the originally curved connecting wire body is deformed between the two groups of cable tie bodies, and the length of the connecting wire body between the two cable tie bodies is much greater than the length of the first lightweight groove, so that the connecting wire body will not bend or break at the connection between the connecting wire body and the laser displacement sensor body due to the pulling force during the movement of the robot arm body during use, thereby ensuring the normal use of the laser displacement sensor body. The arc-shaped design of the protective frame allows the protective frame to produce a certain deformation during the movement of the robot arm body, which not only does not affect the normal use of the robot arm body, but the structure further makes the use effect of the installation mechanism better.

[0020] To sum up, through the mutual cooperation of the installation mechanism and the various components therein, not only can the laser displacement sensor body be quickly installed and fixed on the mechanical arm body for use, which solves the cumbersomeness of the laser displacement sensor body being usually fixed to the mechanical arm body by screws in the past, but also the installation stability is good, ensuring that the sensor is stable and will not shift due to vibration or impact. Moreover, when pulled, the connection between the laser displacement sensor body and the connecting wire body will not be bent or broken due to excessive pulling, thereby ensuring the normal use of the laser displacement sensor body. The device has a simple structure, is convenient and quick to use, and has a low production cost, which is easy to promote and use. BRIEF DESCRIPTION OF THE DRAWINGS

The laser displacement sensor body 3 can be quickly and stably installed on the robot body 1 for use by using the mounting mechanism, which effectively increases the work efficiency of the installation of the laser displacement sensor body 3. The use of the mounting mechanism can also effectively prevent the problem of excessive bending of the connection between the connecting wire body 4 and the laser displacement sensor body 3 during use, thereby ensuring the normal use of the laser displacement sensor body 3 and preventing the connecting wire body 4 from falling to the bottom of the robot body 1 and causing line of sight obstruction. The specific use of the mounting mechanism is described in detail below, and the device has a simple structure, low production cost, and is convenient and quick to use.

[0039] like Figures 1 to 8 As shown, the mounting mechanism includes a mounting frame 5, a protective frame 6 is fixedly connected to the top of the mounting frame 5, a first clamping block 8 is fixedly connected to the end of the mounting frame 5 away from the laser displacement sensor body 3, a second clamping block 9 is fixedly connected to the end of the protective frame 6 away from the laser displacement sensor body 3, a cable tie body 12 is fixedly connected to the protective frame 6, a mounting block 16 is fixedly connected to the side of the mounting frame 5 close to the laser displacement sensor body 3, a cylindrical connecting block is provided at the bottom grasping part of the robot arm body 1, a square connecting block is provided at the rotating mechanism of the robot arm body 1 close to the grasping part of the robot arm body 1, the mounting frame 5 is arranged at the circular connecting block of the robot arm body 1, and the first The lightweight groove 7 is arranged at the square connecting block in the robot arm body 1. The robot arm body 1 is provided with a mounting groove compatible with the mounting block 16 near the grasping part. Through the coordinated use of the first clamping block 8 and the mounting block 16, the laser displacement sensor body 3 can be quickly and stably installed on the robot arm body 1 for use, so as to ensure the accuracy of the grasping work of the robot arm body 1, and reinforcing ribs are arranged in the mounting frame 5 to ensure the stability of the mounting frame 5, so as to further prevent the laser displacement sensor body 3 from positional displacement during use, thereby ensuring that the laser displacement sensor body 3 is stable and will not be displaced due to vibration or impact, thereby ensuring good measurement accuracy. The cable tie body 12 is divided into two groups, one on the side close to the laser displacement sensor body 3 and the other on the side close to the second clamping block 9, and the curved connecting wire body 4 is fixed between the two groups of cable tie bodies 12 in conjunction with the protective frame 6 and the cable tie body 12, so that the protective frame 6 is first pulled when the robot arm body 1 moves, and the deformation range of the protective frame 6 is limited, and the deformation stops when it is stretched to a straight line. In this process, the originally curved connecting wire body 4 is deformed between the two groups of cable tie bodies 12, and the length of the connecting wire body 4 between the two cable tie bodies 12 is much greater than the length of the first lightweight groove 7, so that the connecting wire body 4 will not bend or break at the connection between the connecting wire body 4 and the laser displacement sensor body 3 due to the pulling force during the movement of the robot arm body 1 during use, thereby ensuring the normal use of the laser displacement sensor body 3, and the coordinated use of the structures further improves the practicality of the device.

[0040] like Figures 1 to 8As shown, the mounting frame 5, the protective frame 6, the first clamping block 8 and the second clamping block 9 are integrally constructed. The cross section of the first clamping block 8 is C-shaped. The first clamping block 8 is provided with a first guide portion 10 at one end away from the mounting frame 5. The protective frame 6 is an arc-shaped structure. The protective frame 6 is provided with a first lightweight groove 7. The cross section of the second clamping block 9 is square. The second clamping block 9 is provided with a second guide portion 11 at one end away from the protective frame 6. The integrally constructed structure has better structural stability. The first guide portion 10 provided on the first clamping block 8 and the shape design of the first clamping block 8 enable the first clamping block 8 to be quickly and stably installed on the circular connecting block in the robot arm body 1 by using the guidance of the first guide portion 10. During the installation, the mounting block 16 is squeezed onto the robot arm body 1. The protective frame 6 is installed in the installation groove to achieve the effect of quickly installing the laser displacement sensor body 3, and the arc-shaped design of the protective frame 6 allows the protective frame 6 to produce a certain deformation during the movement of the mechanical arm body 1, which not only does not affect the normal use of the mechanical arm body 1, but also can protect the connecting line body 4 at the bottom of the protective frame 6. The first lightweight groove 7 opened on the protective frame 6 makes the protective frame 6 lighter and more easily deformed by force. At the same time, the second guide portion 11 provided on the second clamping block 9 facilitates the second clamping block 9 to be quickly installed on the square connecting block in the mechanical arm body 1, so as to stably fix the protective frame 6 at the end of the mechanical arm body 1 for use, and the structure is simple, and the coordinated use of the structures further makes the use effect of the installation mechanism better.

[0041] Furthermore, limiting plates 13 are fixedly connected to both sides of the bottom of the protective frame 6. Two limiting plates 13 form a group and are arranged on the protective frame 6 opposite to each other. A storage groove is opened on the protective frame 6. A steel wire body 15 matching the shape of the storage groove at the bottom of the protective frame 6 is installed at the bottom of the protective frame 6. The limiting plates 13 are made of rubber material. A third guide portion 14 is provided at the end of the limiting plate 13 on one side away from the protective frame 6. The steel wire body 15 can be stably fixed to the bottom of the protective frame 6 for use through the provided limiting plates 13, and the third guide portion 14 on the limiting plate 13 can be used to assist in the installation of the steel wire body 15, so that the steel wire body 15 and the protective frame 6 are two independent individuals, which is convenient for the production and use of the structure, and the installation and disassembly are convenient and quick, and the installation stability is good. The setting of the steel wire body 15 enhances the toughness of the protective frame 6, effectively prevents the problem of excessive deformation and breakage of the protective frame 6, and ensures the normal use of the protective frame 6 for a long time.

[0042] like Figures 1 to 8As shown, two reinforcing sheets 17 are arranged opposite to each other on the inner wall of the mounting block 16 on the side close to the laser displacement sensor body 3, a weakened portion 18 is provided on the reinforcing sheet 17, and second lightweight grooves 19 are equidistantly provided on the mounting block 16. A tip is provided on the side of the mounting block 16 close to the robot body 1, and a convex portion is provided on the side of the mounting block 16 close to the laser displacement sensor body 3. By aligning the tip of the mounting block 16 with the mounting groove on the robot body 1, an extrusion force is applied to the mounting block 16. The mounting block 16 is deformed so that the mounting block 16 can be quickly installed on the robot body 1. After the mounting block 16 and the mounting groove on the robot body 1 are completely attached, the deformation rebounds, and the convex portion thereof can confine the mounting block 16 in the mounting groove of the robot body 1. In combination with the use of the mounting frame 5 and the first clamping block 8, the laser displacement sensor body 3 can be further quickly and stably installed on the robot body 1. The design of the reinforcing sheet 17 further strengthens the limiting effect of the convex portion of the mounting block 16. The design of the weakened portion 18 makes it easier for the reinforcing sheet 17 and the mounting block 16 to deform along the weakened portion 18 during installation. The design of the second lightweight groove 19 makes the mounting block 16 lighter, thereby reducing the production cost of the structure. This structure further improves the use effect of the mounting mechanism.

[0043] The working principle of the technical solution provided by the present invention is as follows: when in use, the steel wire body 15 with the same length as the protective frame 6 is first squeezed along the guide of the third guide part 14 to between the two groups of limit plates 13, and the limit plates 13 are deformed first. When the steel wire body 15 is completely stuck between the two groups of limit plates 13, the limit plates 13 rebound to clamp the third guide part 14, and then the tip of the mounting block 16 is aligned with the mounting groove on the robot arm body 1, and the mounting block 16 is pressed to apply extrusion force. The mounting block 16 is deformed, and the mounting block 16 can be quickly installed on the robot arm body 1. After the mounting block 16 and the mounting groove on the robot arm body 1 are completely close to each other, the deformation rebounds, and the convex portion can confine the mounting block 16 in the mounting groove of the robot arm body 1. During this period, the reinforcing sheet 17 is squeezed and deformed along the weakened portion 18. After the mounting block 16 and the mounting groove on the robot arm body 1 are completely close to each other, the reinforcing sheet 17 rebounds to reinforce the mounting block 16. When installing the mounting block 16, the first clamping block 8 connected through the mounting frame 5 is installed on the robot arm body 1 along the guide of the first guide portion 10, and then the second clamping block 9 on one side of the protective frame 6 is installed on the robot arm body 1 along the guide of the second guide portion 11. The connecting wire body 4 passes through the mounting frame 5 and is arranged on the two cable tie bodies 12 in a curved shape. The two tie bodies 12 are then tightened to fix the connecting wire body 4 on the tie body 12. When the robot arm body 1 moves, the protective frame 6 is first driven to move. The protective frame 6 is deformed by the pulling force generated by the movement of the robot arm body 1, and the steel wire body 15 at the bottom of the protective frame 6 is also deformed. The connecting wire body 4 between the two tie bodies 12 is deformed by the pulling force, but it will not be pulled or bent. Therefore, during use, the use of the installation mechanism can also effectively prevent the problem of excessive bending of the connecting wire body 4 at the connection between the laser displacement sensor body 3 during use, thereby ensuring the normal use of the laser displacement sensor body 3 and preventing the connecting wire body 4 from falling to the bottom of the robot arm body 1 to cause line of sight obstruction. In addition, the device has a simple structure, low production cost, and is convenient and quick to use.

In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0045] The above is only a preferred embodiment of the present invention.
