[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] Reference Figure 1-6 The docking station with a correction function includes a frame 100 and a loading rack 200 installed on one side of the frame 100. A material tray 400 is placed on the loading rack 200. The station also includes: a limiting block 201 installed on one side of the loading rack 200 to form a reference edge for positioning the material tray 400; and a positioning component 300 installed on the frame 100 and located on the opposite side of the limiting block 201. The positioning component 300 is configured to be drivably moved toward or away from the limiting block 201 to push the material tray 400 toward the limiting block 201. The positioning correction of the material tray 400 is achieved through the coordinated action of the limiting block 201 and the positioning component 300.

[0036] Furthermore, the limit stop 201 is used as a fixed reference to provide a clear positioning boundary for the tray 400, preventing the cylinder 301 from pushing the tray 400 out of the docking platform. The positioning component 300 generates a thrust pointing towards the limit stop 201 through a driveable motion, so that the tray 400 gradually fits against the limit stop 201 under the action of the thrust. The cooperation of the two constrains the position of the tray 400, eliminating possible translation or deviation when the tray 400 is placed. The rigid cooperation of the mechanical structure realizes the precise correction of the position of the tray 400, ensuring that the tray 400 is in the preset gripping position.

[0037] In the above technical solution, the material tray 400 is accurately positioned through the synergistic effect of the mechanical structure, reducing the failure of the robotic arm 102 to grasp the material. It does not require a complex vision positioning system, thus reducing equipment costs. At the same time, it ensures the stability and consistency of the material tray 400's positioning, improves the efficiency of process connection in the lens processing, and takes into account the precision requirements of the lens.

[0038] Reference Figure 3 The frame 100 includes: a base plate 101, which is mounted on the frame 100; the feeding rack 200 and the positioning component 300 are both mounted on the base plate 101; and four casters 104, which are mounted on the bottom of the frame 100.

[0039] Furthermore, the base plate 101 provides a consistent mounting reference for the loading rack 200 and the positioning assembly 300 through a rigid connection, ensuring the relative positional accuracy of each component during the calibration process; the caster wheel 104 utilizes the adjustable height feature to compensate for ground unevenness by adjusting the height of a single wheel, keeping the top surface of the frame 100 level.

[0040] In the above technical solution, the base plate 101 serves as a unified installation benchmark, which can reduce the relative positional deviation between the loading rack 200 and the positioning component 300, ensuring the matching accuracy of the limit block 201 and the positioning component 300 during the calibration process. The four casters 104 can not only stably support the frame 100, but also adjust the level of the frame 100 to avoid the material tray 400 being tilted due to uneven ground, further ensuring the accuracy of positioning calibration.

[0041] Reference Figure 3 and Figure 4 The positioning component 300 includes: a cylinder 301 mounted on the base plate 101; and a positioning block 303 mounted on the push rod of the cylinder 301. The cylinder 301 is used to control the positioning block 303 to move closer to or further away from the limiting block 201. There are three positioning blocks 303. A connecting plate 302 is mounted on the push rod of the cylinder 301, and all three positioning blocks 303 are mounted on the connecting plate 302. Positioning grooves 401 are provided on both sides of the material tray 400, and the positioning blocks 303 are inserted into the positioning grooves 401.

[0042] Furthermore, the cylinder 301, as a linear drive element, provides directional and controllable thrust to ensure that the material tray 400 moves toward the limit stop 201 along a preset direction; the fitting and engagement of the positioning block 303 and the positioning groove 401, through form and position constraints, limits the positional deviation of the material tray 400 within the guide range of the positioning groove 401.

[0043] In the above technical solution, the three-point synergy of the three positioning blocks 303 enhances the pushing stability of the material tray 400, avoiding tilting or deviation of the material tray 400 caused by single-point pushing. The cooperation between the positioning block 303 and the positioning groove 401 can limit the lateral displacement of the material tray 400 during the pushing process, further improving the correction accuracy. The cylinder 301 drive ensures the stability and controllability of the pushing force, reducing the position deviation of the material tray 400 caused by uneven pushing force.

[0044] Reference Figure 4 The positioning block 303 has a tapered structure that is narrow at the front and wide at the back, which makes it easy to insert into the positioning groove 401 on the material tray 400.

[0045] Reference Figure 2 and Figure 3 The loading rack 200 includes a limiting strip 202, which is installed on the loading rack 200. The limiting strip 202 is located between the positioning block 303 and the limiting stop block 201. The limiting strip 202 is used to limit the position of the material tray 400 on the loading rack 200.

[0046] Furthermore, the limiting strip 202 restricts the translational degree of freedom of the material tray 400 that may be perpendicular to the thrust direction. It complements the reference direction restricted by the limiting block 201 and the thrust direction restricted by the positioning component 300, and together they constrain the three translational and rotational degrees of freedom of the material tray 400 to ensure the effectiveness of the correction action and the consistency of the positioning results.

[0047] The above technical solution can effectively prevent the material tray 400 from shifting or twisting laterally during the process of being pushed towards the limit stop 201 by the positioning component 300, avoid misalignment between the positioning block 303 and the positioning groove 401 caused by the shaking of the material tray 400, ensure that the material tray 400 always moves towards the limit stop 201 along the preset path, further improve the stability of the calibration process and the accuracy of the final positioning, and limit the range of motion of the material tray 400 in advance.

[0048] Reference Figure 3 The feeding rack 200 further includes: a mounting base 203, which is mounted on the feeding rack 200; and a detection component 204, which is mounted on the mounting base 203. The detection component 204 is connected to the cylinder 301 and is used to detect whether there is a material tray 400.

[0049] Furthermore, the detection component 204 adopts a photoelectric sensor, or a pressure sensor. As a sensing unit, the detection component 204 identifies the presence state of the material tray 400, such as blocking light or triggering pressure to generate an electrical signal. This signal serves as the input condition for the control unit of the cylinder 301. When there is a material tray 400, the controller drives the cylinder 301 to act; otherwise, it remains in standby mode.

[0050] Specifically, the signal output terminal of the detection component 204 is connected to the control unit of the cylinder 301 via a wire, which is usually a solenoid valve or a PLC. When the sensor detects the presence of the material tray 400, it outputs a high level, and when the material tray 400 is not present, it outputs a low level, forming an electrical signal indication of the presence or absence of the material tray 400. The solenoid valve of the cylinder 301 receives the command from the control unit and controls the air supply to drive the push rod to extend and retract, thereby realizing the movement of the positioning block 303.

[0051] The above technical solution can realize the automatic triggering of the correction action, avoid the cylinder 301 running in vacancies when there is no material tray 400 or when the material tray 400 is not in place, reduce ineffective energy consumption and mechanical wear, and ensure that the correction action of the positioning component 300 is only started when the material tray 400 is actually placed on the loading rack 200, thereby improving the accuracy and safety of the correction process.

[0052] Reference Figure 1It also includes: an AGV trolley 500, which is set on one side of the frame 100; and a transport fixture 501, which is installed on the lifting platform of the AGV trolley 500. The transport fixture 501 is used to transport the material tray 400 and unload the material tray 400 onto the loading rack 200.

[0053] Furthermore, the AGV trolley 500 uses its own navigation system to achieve precise alignment with the frame 100, ensuring the relative positional accuracy of the transport fixture 501 and the loading rack 200; the lifting platform eliminates the height difference between the AGV trolley 500 and the docking platform through height adjustment, ensuring a horizontal transition when the material tray 400 is unloaded; the transport fixture 501 smoothly transfers the material tray 400 from the AGV trolley 500 to the loading rack 200.

[0054] The above technical solution enables automated transfer and unloading of the material tray 400 from storage or previous process to the docking station, reducing errors and labor intensity of manual handling. The precise positioning of the AGV trolley 500 and the height adjustment of the lifting platform can ensure the docking accuracy between the transport tooling 501 and the loading rack 200.

[0055] Reference Figure 1 The base plate 101 includes: a robotic arm 102 mounted on the base plate 101; and an electric gripper 103 mounted on the end effector of the robotic arm 102.

[0056] Furthermore, the robotic arm 102 matches the position of the calibrated tray 400 with a preset motion trajectory and achieves spatial positioning through multi-axis linkage; the electric gripper 103 adjusts the gripping force according to the material and weight of the tray 400, ensuring a stable grip while avoiding damage to the tray 400 or the lens.

[0057] In the above technical solution, the rigid connection between the robotic arm 102 and the base plate 101 is used to ensure the motion accuracy of the robotic arm 102 by utilizing the stable reference of the base plate 101. Combined with the accurate position of the material tray 400 after being corrected by the positioning component 300, the success rate of the electric gripper 103 is improved.

[0058] The following is a brief introduction to the operating principle and method of the docking station with correction function proposed in this application: By adjusting the four casters 104 at the bottom of the frame 100, the base plate 101 is kept horizontal, ensuring that the installation reference of the loading rack 200, positioning component 300 and robotic arm 102 are consistent, providing a stable foundation for subsequent actions. The AGV trolley 500 is positioned to one side of the frame 100 through its own navigation system, and its lifting platform adjusts the height of the transport fixture 501 so that the height of the transport fixture 501 matches that of the loading rack 200; the transport fixture 501... The material tray 400 is smoothly transferred and unloaded onto the loading rack 200. Initially, the material tray 400 is positioned between the limit stop 201 and the positioning component 300, within the range defined by the limit strip 202. Upon sensing the material tray 400, the detection component 204 on the loading rack 200 outputs a material presence electrical signal to the cylinder 301 control unit. Upon receiving the signal, the control unit drives the cylinder 301 to start, extending the cylinder 301 push rod. This push rod, via the connecting plate 302, drives the three conical positioning blocks 303 to move synchronously towards the limit stop 201. 03 The front end is embedded in the positioning grooves 401 on both sides of the material tray 400. Under the action of thrust, the material tray 400 is pushed to move towards the limiting block 201. During the process, the limiting strip 202 restricts the offset of the material tray 400 perpendicular to the direction of thrust, so as to prevent the positioning block 303 from being misaligned with the positioning groove 401. Finally, the material tray 400 fits against the reference edge of the limiting block 201, completing the translation and deviation correction. After the correction is completed, the positioning signal can be fed back through the pressure sensor or the magnetic ring sensor of the cylinder 301. The control unit commands the cylinder 301 to reset, and the push rod drives the positioning block 301 to move. 03. Return to the initial position and disengage from the positioning slot 401 of the material tray 400. The robotic arm 102 on the base plate 101 moves along the preset trajectory. The electric gripper 103 at the execution end adjusts the gripping force according to the characteristics of the material tray 400 to accurately grasp the calibrated material tray 400. After the grasping is completed, the robotic arm 102 moves the material tray 400 to the next process. After the robotic arm 102 takes away the material tray 400, the detection component 204 outputs a no-material signal, and the cylinder 301 remains in standby state. The AGV trolley 500 can transport a new material tray 400 to the transfer station again.

[0059] In summary, compared with the prior art, the docking station with correction function proposed in this application has the following advantages:

[0060] Beneficial effects:

[0061] Through the coordinated action of the limit stop 201 and the positioning component 300, the active thrust of the positioning component 300 pushes the material tray 400 toward the reference edge. Combined with the lateral constraint of the limit strip 202, the translation and deviation of the material tray 400 can be effectively eliminated, and the positional accuracy can be controlled within the reliable gripping range of the robotic arm 102, ensuring the smoothness of process connection.

[0062] By using limit stop 201, positioning block 303 and cylinder 301 to achieve correction, and by replacing visual recognition with rigid cooperation, the high investment in vision system is avoided, and the cost of complex algorithm debugging and maintenance is reduced, thus reducing the overall cost of the equipment and making it more suitable for the economic needs of mass production scenarios.

[0063] Through the linkage control of the detection component 204 and the cylinder 301, the detection component 204 senses the status of the material tray 400 in real time and triggers correction. After the correction is completed, the robotic arm 102 directly grabs it. The whole process does not require manual intervention, which reduces the intermediate waiting time and improves the overall efficiency of transferring the material tray 400 to the next process.
