Description

Technical Field

[0001] This application relates to the field of optical storage technology, and in particular to a mounting fixture for the optical axis guide rail of an optical disc manipulator. Background Technology

[0002] In the field of optical storage technology, optical axis guides, as core guiding components of robotic arm motion systems, directly affect the positioning accuracy and operational stability of data storage devices. Traditional optical axis guide assembly processes primarily rely on manual operation, which suffers from the following technical drawbacks: First, due to the lack of high-precision positioning benchmarks and calibration mechanisms, axial position deviations and parallelism errors are easily generated during guide installation. Second, manual assembly processes are significantly affected by differences in operator skill levels and environmental factors, making it difficult to guarantee consistent assembly quality. These assembly defects can lead to positioning deviations, abnormal vibrations, and increased noise during robotic arm movement, not only reducing data read / write accuracy but also shortening the lifespan of critical moving components.

[0005] The fixture body has a positioning groove that extends vertically and penetrates the fixture body both above and below. One side of the positioning groove penetrates the first sidewall of the fixture body to form an installation opening. The installation opening is used for the optical axis guide rail to enter and exit the positioning groove laterally. The positioning groove is used to cooperate with the optical axis guide rail.

[0006] At least two locating pins are provided on the main body of the fixture, and the at least two locating pins are arranged at intervals along the lateral direction. Each locating pin is used to mate with a corresponding locating hole on the main body of the chassis; and

[0007] A magnetic suction component is disposed on the main body of the fixture. The magnetic suction component is used to magnetically engage with the main body of the chassis, or the magnetic suction component is used to engage with a magnetically conductive component on the main body of the chassis to install the main body of the fixture onto the main body of the chassis.

[0008] In one embodiment, the positioning pin and the magnetic attraction component are both disposed on the second side wall of the fixture body. The second side wall and the first side wall are both located on the same side of the fixture body, and the second side wall and the first side wall are arranged sequentially in the transverse direction. The second side wall is used to fit against the chassis body.

[0009] In one embodiment, the number of magnetic components is at least two, and the at least two magnetic components are arranged at intervals along the lateral direction.

[0010] In one embodiment, the magnetic attraction component and the positioning pin are arranged alternately in a transverse direction.

[0011] In one embodiment, the fixture body has at least two first mounting slots, the first end of each positioning pin is inserted into the corresponding first mounting slot, and the second end of each positioning pin extends out of the fixture body.

[0012] In one embodiment, each of the positioning pins is fixed to the wall of the corresponding first mounting groove by adhesive.

[0013] In one embodiment, the fixture body further has a second mounting groove that is adapted to the magnetic suction component.

[0019] And / or, the magnetic attraction component is a permanent magnet.

[0020] The advantages or beneficial effects of the above technical solutions include at least the following:

[0021] The installation fixture of this utility model solves the problem of insufficient installation accuracy of optical axis guide rails through the coordinated cooperation of the fixture body, positioning pins, and magnetic components. Specifically, the vertical through-type positioning groove of the fixture body allows the optical axis guide rail to be inserted laterally through the installation port, and the inner wall of the positioning groove is precisely matched with the outer diameter of the optical axis guide rail to achieve radial positioning; at least two laterally spaced positioning pins are inserted into the corresponding positioning holes of the chassis body to form an axial positioning reference and eliminate axial position deviation; the magnetic components are directly magnetically attracted to the chassis body or indirectly attracted through the magnetically conductive components, so that the fixture body is quickly and accurately positioned on the chassis body. The installation principle is as follows: During assembly, the main body of the fixture is first fixed to the preset position of the main body of the chassis by positioning pins and magnetic components to form a high-precision assembly benchmark. Then, the optical axis guide rail is pushed laterally into the positioning groove along the installation port. The fixture body's forced constraint on the optical axis guide rail ensures that its relative position with the main body of the chassis meets the requirements of parallelism and coaxiality, thereby eliminating manual assembly deviations and realizing standardized high-precision installation of the optical axis guide rail. The optical axis guide rail is then fixed. This effectively controls the assembly error of the optical axis guide rail within a very small range, meets the high-precision assembly requirements of data storage devices for optical axis guide rails, and significantly improves the motion accuracy and stability of the robot.

[0022] Secondly, the installation fixture has a reasonable structural design and is easy to operate. It can quickly complete the positioning, calibration and fixing of the optical axis guide rail. Compared with the traditional ordinary installation method, it greatly shortens the installation time and improves the installation efficiency.

[0023] Furthermore, because the installation fixture has precise positioning and calibration functions, operators do not need to perform complex manual adjustments, which reduces labor intensity and also reduces installation errors caused by improper manual operation, thus improving the stability of installation quality.

[0024] Furthermore, the structure and dimensions of this installation fixture can be flexibly adjusted and customized according to different models of data storage devices and optical axis guide rails, which has strong versatility and can adapt to a variety of different application scenarios, reducing the equipment modification costs for enterprises.

[0025] In addition, the installation fixture has a simple structure, low cost, and is easy and convenient to install and operate, making it more conducive to widespread application.

[0031] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0032] See Figures 1-2 This invention illustrates a preferred embodiment of a mounting fixture for an optical axis guide rail of a CD-ROM robotic arm. The optical axis guide rail 5 is mounted on the chassis body 6 and includes:

[0033] The fixture body 1 is provided with a positioning groove 11. The positioning groove 11 extends vertically and penetrates the fixture body 1 both above and below. One side of the positioning groove 11 penetrates the first side wall of the fixture body 1 to form an installation port. The installation port is used for the optical axis guide rail 5 to enter and exit the positioning groove 11 laterally. The positioning groove 11 is used to cooperate with the optical axis guide rail 5.

[0034] At least two locating pins 2 are provided on the fixture body 1, and are arranged at intervals along the lateral direction. Each locating pin 2 is used to mate with a corresponding locating hole 61 on the chassis body 6; and

[0035] The magnetic component 3 is disposed on the fixture body 1. The magnetic component 3 is used to magnetically engage with the chassis body 6, or the magnetic component 3 is used to engage with the magnetic conductive component (not shown in the figure) on the chassis body 6 to install the fixture body 1 onto the chassis body 6.

[0036] The installation fixture of this utility model solves the problem of insufficient installation accuracy of the optical axis guide rail 5 through the coordinated cooperation of the fixture body 1, the positioning pins 2, and the magnetic attraction component 3. Specifically, the vertical through-type positioning groove 11 of the fixture body 1 allows the optical axis guide rail 5 to be installed laterally through the installation port, and the inner wall of the positioning groove 11 is precisely matched with the outer diameter of the optical axis guide rail 5 to achieve radial positioning; at least two horizontally spaced positioning pins 2 are inserted into the corresponding positioning holes 61 of the chassis body 6 to form an axial positioning reference and eliminate axial position deviation; the magnetic attraction component 3 is directly magnetically attracted to the chassis body 6 or indirectly attracted through the magnetic conductive component, so that the fixture body 1 is quickly and accurately positioned on the chassis body 6. The installation principle is as follows: During assembly, the main body 1 of the fixture is first fixed to the preset position of the main body 6 of the chassis by the positioning pin 2 and the magnetic suction component 3 to form a high-precision assembly benchmark. Then, the optical axis guide rail 5 is pushed laterally into the positioning groove 11 along the installation port. The fixture main body 1 provides a forced constraint on the optical axis guide rail 5 to ensure that its relative position with the main body 6 of the chassis meets the requirements of parallelism and coaxiality, thereby eliminating manual assembly deviation and realizing the standardized high-precision installation of the optical axis guide rail 5. Then, the optical axis guide rail 5 is fixed. This can effectively control the assembly error of the optical axis guide rail 5 within a very small range, meet the requirements of data storage devices for high-precision assembly of the optical axis guide rail 5, and significantly improve the motion accuracy and stability of the robot.

[0037] In one embodiment, two sets of mounting fixtures for the optical axis guide rail of the optical disc manipulator are used. The two sets of mounting fixtures are arranged vertically spaced along the chassis body 6. In this way, the two sets of mounting fixtures arranged vertically spaced along the chassis body 6 work together to ensure the straightness and parallelism of the optical axis guide rail 5 along its entire length through the upper and lower double positioning references, effectively eliminating the cumulative error that may be caused by single-point positioning. During installation, the two fixture bodies 1 are precisely matched with the corresponding positioning holes 61 of the chassis body 6 through their respective positioning pins 2. At the same time, the magnetic suction component 3 firmly attaches the upper and lower fixture bodies 1 to the chassis body 6 to form a rigid connection. When the optical axis guide rail 5 passes through the through-type positioning grooves 11 of the upper and lower fixtures in sequence, the coaxial constraint of the upper and lower positioning grooves 11 forces the optical axis guide rail 5 to automatically correct bending deformation and angular deviation, forming a synchronous calibration effect at both ends. This makes the installation straightness of the optical axis guide rail 5 on the chassis body 6 reach a higher precision level, which is especially suitable for the high standard assembly requirements of long-stroke manipulators.

[0038] Of course, in other embodiments, during installation, only one or more sets of installation fixtures may be configured. When only one set of installation fixtures is configured, the vertical dimension of the positioning groove 11 should be as long as possible to ensure the straightness and parallelism of the optical axis guide rail 5 throughout its entire length.

[0039] It should be noted that the number of positioning slots 11 is the same as the number of optical axis guide rails 5 to be installed, in order to improve installation efficiency.

[0040] It is understood that the chassis body 6 is generally made of iron. In this case, by utilizing the iron material properties of the chassis body 6 itself, the magnetic component 3 can be directly attached to the chassis body 6 to achieve quick positioning and fixation. There is no need to perform additional processing on the chassis body 6 or add magnetic components, which simplifies the assembly process and reduces costs.

[0041] Of course, in other embodiments, a magnetic conductive component (not shown in the figure) can be added to the chassis body 6, and the magnetic attraction component 3 can be attracted to the magnetic conductive component, thereby indirectly fixing the jig body 1 to the chassis body 6.

[0042] In one embodiment, the magnetic attraction component 3 is a permanent magnet. Using a permanent magnet as the magnetic attraction component 3 can achieve stable magnetic attraction and fixation without external energy, which simplifies the installation fixture structure and improves assembly reliability. At the same time, the permanent magnet has durable physical properties and can maintain magnetic stability for a long time to ensure the accuracy of repeated assembly.

[0043] Of course, in other embodiments, the magnetic attraction component 3 can also be an electromagnet. The electromagnet generates a controllable magnetic attraction force by being energized, which facilitates rapid demolding after assembly. During installation, the strong magnetic field generated by energizing during the assembly stage attracts the main body 6 of the chassis. When disassembling, the magnetic force can be released by disconnecting the power, thus avoiding displacement of the main body 1 of the fixture from affecting the installation reference.

[0044] See Figure 1 In one embodiment, the positioning pin 2 and the magnetic suction component 3 are both disposed on the second side wall of the fixture body 1. The second side wall and the first side wall are both located on the same side of the fixture body 1, and the second side wall and the first side wall are arranged sequentially in the transverse direction. The second side wall is used to fit against the chassis body 6. Thus, by integrating the positioning pin 2 and the magnetic component 3 on the second sidewall of the same side as the fixture body 1, and with the first sidewall where the mounting port is located arranged laterally, a compact integrated positioning and adsorption structure is formed. This ensures the stability of the fit between the fixture body 1 and the chassis body 6, while avoiding interference with the lateral installation operation of the optical axis guide rail 5. During assembly, the fixture body 1 fits the surface of the chassis body 6 as a whole through the second sidewall. The positioning pin 2 is precisely inserted into the positioning hole 61 of the chassis body 6 to achieve radial constraint. At the same time, the magnetic component 3 directly adsorbs the surface of the chassis body 6 to generate normal clamping force, so that the fixture body 1 forms a three-point stable installation reference. At this time, the mounting port of the first sidewall remains open, allowing the optical axis guide rail 5 to slide laterally into or out of the positioning groove 11 without obstruction. This layout optimizes the utilization of assembly space while ensuring positioning accuracy, achieving a balance between high precision and ease of operation.

[0045] See Figure 1In one embodiment, the number of magnetic suction components 3 is at least two, and the at least two magnetic suction components 3 are arranged laterally at intervals. By setting at least two laterally spaced magnetic suction components 3 to form a multi-point magnetic suction fixing structure, the adsorption stability between the fixture body 1 and the chassis body 6 can be enhanced, effectively preventing the fixture body 1 from deflecting or shifting during the assembly of the optical axis guide rail 5. At the same time, the evenly distributed magnetic attraction force at multiple points can avoid local stress concentration and ensure the full fit between the fixture body 1 and the chassis body 6. In addition, since multiple magnetic suction components 3 are arranged laterally along the second side wall of the fixture body 1, when the positioning pin 2 is inserted into the positioning hole 61 of the chassis body 6, each magnetic suction component 3 generates an adsorption force synchronously, so that the fixture body 1 obtains a balanced fixing effect in the length direction. Even when facing the assembly operation of heavy optical axis guide rail 5, this multi-point magnetic suction structure can still maintain the accurate positioning state of the installation fixture, thereby improving the consistency of assembly accuracy. It is particularly suitable for the installation requirements of large-size chassis body 1 or optical axis guide rail 5 under high load conditions.

[0046] See Figure 1 In one embodiment, the magnetic suction component 3 and the positioning pin 2 are arranged alternately in the transverse direction. By arranging the magnetic suction component 3 and the positioning pin 2 alternately in the transverse direction, the structural space utilization of the fixture body 1 is optimized, and a complementary positioning and fixing effect is formed. This allows the fixture body 1 to achieve both mechanical positioning and magnetic fixing functions within a limited installation space, effectively improving assembly stability and accuracy. In addition, since the magnetic suction component 3 and the positioning pin 2 are alternately distributed on the second side wall of the fixture body 1, when the fixture is installed, the positioning pin 2 is first inserted into the positioning hole 61 of the chassis body 6 to complete the initial positioning. Subsequently, the alternately arranged magnetic suction component 3 is attracted to the surface of the chassis body 6 in sequence. This alternate layout allows the mechanical positioning point and the magnetic fixing point to cooperate with each other, forming a uniformly distributed constraint force in both the transverse and longitudinal directions. This avoids micro-displacement or deflection caused by uneven force on the fixture body 1, ensuring that the fixture body 1 remains absolutely stable when the optical axis guide rail 5 is installed in the positioning groove 11, thereby achieving high-precision assembly requirements in a compact space.

[0047] See Figure 1 In one embodiment, the fixture body 1 has at least two first mounting slots 12, with the first end of each positioning pin 2 inserted into the corresponding first mounting slot 12, and the second end of each positioning pin 2 extending outward to the outside of the fixture body 1. Thus, by providing multiple first mounting slots 12 on the fixture body 1 to fix the positioning pins 2, the first end of the positioning pin 2 is securely inserted into the first mounting slot 12, while the second end of the positioning pin 2 extends outward and inserts into the positioning hole 61 of the chassis body 6. This ensures the connection strength and positional accuracy between the positioning pin 2 and the fixture body 1, thereby improving the positioning accuracy of the positioning pin 2.

[0048] In one embodiment, each locating pin 2 is fixed to the wall of the corresponding first mounting groove 12 by adhesive. Using adhesive to firmly bond the locating pin 2 to the first mounting groove 12 ensures the connection strength and positional accuracy between the locating pin 2 and the fixture body 1, while avoiding the loosening problems that may occur with traditional threaded connections. Furthermore, the adhesive's gap-filling properties effectively eliminate minor displacements caused by assembly tolerances. In addition, since the first end of each locating pin 2 forms a fully circumferentially cured adhesive layer with the inner wall of the first mounting groove 12 through high-strength adhesive, while maintaining the precise extension length of the second end of the locating pin 2, the elastic modulus of the adhesive can absorb minor vibrations during the assembly process of the optical axis guide rail 5, preventing relative displacement between the locating pin 2 and the fixture body 1. This fixing method simplifies the production process while improving the long-term stability of the positioning structure, ensuring that the optical axis guide rail 5 maintains consistent positioning accuracy during repeated assembly.

[0049] Of course, in other embodiments, the locating pin 2 can also be fixed to the first mounting groove 12 by means of threads.

[0050] See Figure 1 In one embodiment, the fixture body 1 also has a second mounting groove 13, which is adapted to the magnetic suction component 3. By providing a second mounting groove 13 adapted to the magnetic suction component 3 on the fixture body 1, the magnetic suction component 3 can be securely embedded in the fixture body 1 to form an integrated structure. This ensures the accuracy and stability of the installation position of the magnetic suction component 3 and avoids the risk of interference or damage that may occur with exposed magnetic suction components 3. In addition, since the shape and size of the second mounting groove 13 match the magnetic suction component 3, the magnetic suction component 3 is fixed in the second mounting groove 13 by interference fit or bonding. After the fixture body 1 is initially positioned with the chassis body 6 by the positioning pin 2, the magnetic suction component 3 embedded in the second mounting groove 13 makes close contact with the surface of the chassis body 6 to generate a uniform adsorption force. This built-in magnetic suction structure optimizes the overall contour of the fixture body 1 while maintaining sufficient magnetic suction strength, making the assembly process of the optical axis guide rail 5 smoother and improving the durability and reliability of the mounting fixture under complex working conditions.

[0051] See Figure 1In one embodiment, the magnetic suction component 3 is fixed to the fixture body 1 by fasteners 4. The rigid connection between the magnetic suction component 3 and the fixture body 1 via fasteners 4 ensures the positional stability of the magnetic suction component 3 during long-term use and facilitates disassembly and replacement to adapt to different adsorption force requirements or maintenance needs. The magnetic suction component 3 is detachably fixed to the fixture body 1 by fasteners 4 such as screws or bolts. After the fixture body 1 is positioned with the chassis body 6 by the positioning pin 2, the magnetic suction component 3, locked by the fasteners 4, maintains a constant contact pressure with the surface of the chassis body 6. This mechanical fixing method overcomes the displacement risks that may arise from relying solely on magnetic force or adhesion, maintaining a stable adsorption effect even under vibration conditions. Furthermore, the adjustable preload of the fasteners 4 allows for controllable contact tightness between the magnetic suction component 3 and the chassis body 6, thereby improving the adaptability and maintenance convenience of the installation fixture while ensuring assembly accuracy.

[0052] In one embodiment, the fixture body 1 also has a threaded hole (not shown in the figure), which is located on the bottom wall of the second mounting groove 13;

[0053] The magnetic component 3 has a connection hole (not shown in the figure);

[0054] The head of the fastener 4 abuts against the magnetic component 3. The rod of the fastener 4 passes through a connecting hole and is screwed into a threaded hole, meaning the fastener 4 is specifically a screw. Thus, by providing a threaded hole in the bottom wall of the second mounting groove 13 of the fixture body 1, and a corresponding connecting hole in the magnetic component 3, during assembly, the rod of the fastener 4 passes through the connecting hole and screws into the threaded hole in sequence. The head of the fastener 4 presses against the upper surface of the magnetic component 3 to form an axial constraint. This structure ensures that the bottom surface of the magnetic component 3 is tightly fitted to the bottom wall of the mounting groove. While maintaining accurate positioning of the magnetic component 3, the preload of the threaded connection effectively prevents loosening and displacement of the magnetic component 3 during operation, ensuring that the fixture body 1 and the chassis body 6 maintain a stable relative position during the assembly of the optical axis guide rail 5. Furthermore, this modular design facilitates quick replacement of magnetic components 3 with different magnetic forces according to different working conditions.

[0055] It is understood that the sidewall where the head of the magnetic component 3 abuts against the head of the fastener 4 has a receiving hole (not shown in the figure). The receiving hole is coaxially arranged with the connecting hole and communicates with the connecting hole. The rod part of the fastener 4 is located in the receiving hole. In this way, by setting a stepped installation structure with a receiving hole coaxial with the connecting hole on the magnetic component 3, the head of the fastener 4 can be completely sunk into the interior of the magnetic component 3. This maintains the maximum effective contact area between the magnetic component 3 and the main body of the chassis 6 to ensure the adsorption strength, while avoiding interference problems caused by the head of the fastener 4 protruding.

[0056] In summary, this installation fixture has the following advantages:

[0057] Improve assembly accuracy: The optical axis guide rail 5 is precisely positioned by two sets of positioning pins, and the perpendicularity of the optical axis guide rail 5 is accurately calibrated by the positioning groove 11. This effectively controls the assembly error of the optical axis guide rail 5 within a very small range, meets the high-precision assembly requirements of data storage devices for the optical axis guide rail 5, and significantly improves the motion accuracy and stability of the robot.

[0058] Improved installation efficiency: The installation fixture has a reasonable structural design and is easy to operate. It can quickly complete the positioning, calibration and fixing of the optical axis guide rail 5. Compared with the traditional installation method, it greatly shortens the installation time and improves production efficiency.

[0059] Reduced labor intensity: Because the installation fixture has precise positioning and calibration functions, operators do not need to perform complicated manual adjustments, which reduces labor intensity and also reduces installation errors caused by improper manual operation, thus improving the stability of installation quality.

[0060] High versatility: The structure and dimensions of this installation fixture can be flexibly adjusted and customized according to different models of data storage devices and optical axis guide rails 5, which has strong versatility and can adapt to a variety of different application scenarios, reducing the equipment modification costs for enterprises.
