Description

Technical Field

[0001] The present invention relates to the technical field of industrial coding, and particularly to an automatic coding and loading mechanism. Background Art

[0002] In industrial production, the coding and loading of workpieces are key links affecting the overall efficiency. In the traditional production process, this link highly depends on manual operation: workers need to manually pick up workpieces from the conveyor belt, visually align the position of the coding machine and then trigger coding, and after completion, they also need to transfer the workpieces to the next process.

[0003] However, this manual operation method has significant defects. First, the efficiency of manual operation is limited by the reaction speed and physical strength of workers. Especially during continuous operation, workers are prone to slow actions or mistakes due to fatigue, making it difficult to meet the high production capacity requirements of modern production lines. Second, the accuracy of manual coding completely depends on the experience and concentration of operators, and problems such as offset coding positions, missing codes, or duplicate coding are likely to occur, directly affecting product quality and consistency.

[0004] Therefore, the present application provides an automatic coding and loading mechanism to solve the above technical problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an automatic coding and loading mechanism to solve the problems of low efficiency and deviation of coding positions caused by manual operation in the process of coding and loading workpieces in the prior art.

[0006] To solve the above technical problems, the present invention provides the following technical solutions:

[0007] An automatic coding and loading mechanism, comprising a workpiece conveying mechanism, a manipulator, a gripper mechanism, a coding workbench, a laser coding machine, and a turnover and temporary storage table;

[0008] One end of the workpiece conveying mechanism is cooperated with one side of the manipulator. A rotatable gripper mechanism is installed on the manipulator, and a coding workbench is correspondingly arranged on the other side of the manipulator. A laser coding machine and a turnover and temporary storage table are provided on the coding workbench;

[0009] The workpiece conveying mechanism is used to convey workpieces to the grasping position of the manipulator, and the manipulator grabs the workpieces through the gripper mechanism and transports them to the laser coding machine for coding, and places the coded workpieces on the turnover and temporary storage table. The manipulator re-grabs the workpieces for loading after flipping the gripper mechanism.

[0010] As a further preferred solution, the workpiece conveying mechanism includes a frame, a conveyor belt, a driving motor, and a receiving plate. The conveyor belt is installed on the upper end surface of the frame and is driven by the driving motor. The receiving plate is arranged at the end thereof for intercepting the workpiece and making it stay at the grasping position of the manipulator.

[0011] As a further preferred solution, a plurality of gantry frames are erected on the frame, and a plurality of adjustable workpiece limiting strips are fixed below the gantry frames. The plurality of workpiece limiting strips divide the upper end surface of the conveyor belt into multiple conveying paths.

[0012] As a further preferred solution, a horizontal installation groove is provided at the top of the gantry frame, and a vertical fixing column is installed on the workpiece limiting strip. The top end of the fixing column is slidably installed in the installation groove.

[0013] As a further preferred solution, the jaw mechanism includes a driving arm, a rotating seat, and a driving module. The driving arm is fixed to the manipulator, and a rotating seat is movably installed at the end of the driving arm. Two driving modules are symmetrically installed on one side of the rotating seat away from the driving arm.

[0014] As a further preferred solution, clamping jaw teeth are provided on both of the two driving modules. The two clamping jaw teeth are mirror-matched under the action of the two driving modules to realize the clamping and releasing of the workpiece.

[0015] As a further preferred solution, the manipulator is a FANUC series manipulator with a load capacity of not less than 10 kg, and the motion path is planned to avoid interference between the jaw mechanism and the feeding area.

[0016] As a further preferred solution, a vision detection module is provided on one side of the laser marking machine close to the manipulator for identifying the workpiece position and controlling the laser marking parameters.

[0017] As a further preferred solution, an infrared detection module is provided beside the turnover temporary storage table. The infrared detection module is used to detect the existence state of the temporarily stored workpiece and trigger the manipulator to flip the jaw mechanism and then perform a secondary feeding action.

[0018] As a further preferred solution, the mechanism further includes a central control box for synchronously controlling the coordinated actions of the manipulator, the laser marking machine, the driving motor, and the detection module.

[0019] Compared with the prior art, the present invention has at least the following beneficial effects:

[0020] In the above solution, thanks to the coordinated action of the manipulator and the gripper mechanism, the automatic grasping, transfer, coding, and feeding of workpieces are realized, and the whole process does not require manual intervention, significantly improving production efficiency and production capacity stability, and solving the problems of low efficiency and dependence on labor in traditional manual coding.

[0021] In the above solution, thanks to the real-time recognition of the workpiece position and features by the vision detection module and the adaptive adjustment of coding parameters by the laser coder, the coding accuracy and consistency can be ensured, and the misalignment or missing code phenomenon caused by manual operation can be avoided.

[0022] In the above solution, thanks to the real-time monitoring of the workpiece status on the turnover and temporary storage table by the infrared detection module and the synchronous coordination of the manipulator movement, laser coding start / stop, and conveyor belt operation by the central control box, a full-process closed-loop control is achieved, ensuring seamless connection of the production rhythm.

[0023] In summary, through the integration of automation, intelligence, and modularization technologies, the present invention comprehensively optimizes the deficiencies of traditional coding processes, has significant advantages such as high efficiency, precision, flexibility, and reliability, and has a good overall use effect.

[0039] As Figure 1 shown, an embodiment of the present invention provides an automatic coding and loading mechanism, including a workpiece conveying mechanism 1, a manipulator 2, a jaw mechanism 3, a coding workbench 4, a laser coding machine 5, and a turnover and temporary storage table 6. Among them, one end of the workpiece conveying mechanism 1 is cooperated with one side of the manipulator 2, a reversible jaw mechanism 3 is installed on the manipulator 2, and a coding workbench 4 is correspondingly arranged on the other side of the manipulator 2. A laser coding machine 5 and a turnover and temporary storage table 6 are provided on the coding workbench 4.

[0040] During specific operation, the workpiece conveying mechanism 1 is used to convey the workpiece to the grasping position of the manipulator 2, and the manipulator 2 grabs the workpiece through the jaw mechanism 3 and transfers it to the laser coding machine 5 for coding, and places the workpiece after coding on the turnover and temporary storage table 6. The manipulator 2 re-grabs the workpiece for loading after flipping the jaw mechanism 3.

[0041] As Figure 2 With Figure 3 shown, the workpiece conveying mechanism 1 includes a frame 101, a conveyor belt 102, a driving motor 103, and a receiving plate 104. The conveyor belt 102 is installed on the upper end surface of the frame 101. The conveyor belt 102 may specifically be made of, but not limited to, wear-resistant rubber material, with anti-slip patterns on the surface, and is driven by the driving motor 103 at an adjustable speed of 0.1 - 1.5 m / s to ensure stable conveyance of the workpiece. And the receiving plate 104 is arranged at the end of the 101 for intercepting the workpiece to make it stay at the grasping position of the manipulator 2.

[0042] Meanwhile, several gantry frames 105 are mounted on the frame 101, and a plurality of adjustable workpiece limiting bars 106 are fixed below the gantry frames 105. The plurality of workpiece limiting bars 106 divide the upper surface of the conveyor belt 102 into multiple conveying paths. During specific implementation, a horizontal installation groove 107 is provided at the top of the gantry frame 105, and a vertical fixing column 108 is installed on the workpiece limiting bar 106. The top end of the fixing column 108 is slidably installed in the installation groove 107. Therefore, the distance between the workpiece limiting bars 106 is adjusted through the sliding fit between the fixing column 108 and the installation groove 107, so as to adapt to the positioning requirements of workpieces of different specifications.

[0043] As Figure 4 shown in Figure 5 Figure, a base 201 is provided at the bottom of the manipulator 2, and a gripper mechanism 3 is provided at the top end of the manipulator 2. The gripper mechanism 3 includes a driving arm 301, a rotating seat 302, and a driving module 303. Among them, the driving arm 301 is fixed to the manipulator 2, and a rotating seat 302 is movably installed at the end of the driving arm 301. Two driving modules 303 are symmetrically installed on one side of the rotating seat 302 away from the driving arm 301.

[0044] Moreover, clamping claw teeth 304 are provided on both of the two driving modules 303. The two clamping claw teeth 304 are mirror - cooperated under the action of the two driving modules 303 to realize the clamping and releasing of the workpiece. During specific implementation, the manipulator 2 is a FANUC series manipulator with a load capacity of not less than 10 kg, and the motion path is planned to avoid interference between the gripper mechanism 3 and the feeding area.

[0045] During specific implementation, the driving arm 301 can be made of, but is not limited to, lightweight aluminum alloy material. The rotating seat 302 is internally provided with a harmonic reducer and can realize a ±180° flip. The driving module 303 can be, but is not limited to, pneumatic servo drive, and the surface of the clamping claw teeth 304 is covered with a polyurethane anti - slip layer, and the adjustable range of its clamping force is 5 - 50 N, so as to facilitate the non - destructive grasping of workpieces of different materials.

[0046] As Figure 6As shown in the figure, a vision detection module 501 is provided on one side of the laser coding machine 5 close to the manipulator 2, which is used to identify the workpiece position and control the laser coding parameters. At the same time, an infrared detection module 601 is provided beside the turnover and temporary storage table 6. The infrared detection module 601 is used to detect the presence state of the temporarily stored workpiece and trigger the manipulator 2 to flip the jaw mechanism 3 and then perform a secondary loading operation. Specifically, the laser coding machine 5 can adopt, but is not limited to, a fiber laser, with a power of 20W, a coding accuracy of ±0.1mm, and can support complex markings such as two-dimensional codes and serial numbers. The turnover and temporary storage table 6 can specifically be made of stainless steel, with a ceramic anti-scratch coating sprayed on the surface, and can carry workpieces with a maximum weight of 50kg.

[0047] In addition, in this embodiment, a central control box 7 is also incorporated in the automatic coding and loading mechanism of the present invention. A central controller is provided in the central control box 7, which can specifically be selected from, but is not limited to, a PLC controller (such as Siemens S7-1200), and communicates with the manipulator 2, the laser coding machine 5, and the detection module in real time through an industrial Ethernet to achieve coordinated control of multiple devices.

[0048] The working principle provided by the present invention, for this automatic coding and loading mechanism, during use, the workpiece conveying mechanism 1 drives the conveyor belt 102 through the drive motor 103, and orderly conveys the workpiece to be processed along a multi-channel adjustable conveying path to the grasping position of the manipulator 2. Among them, the workpiece limiting strip 106 under the gantry frame 105 realizes the spacing adjustment through the sliding fit of the fixed column 108 and the installation groove 107, so as to adapt to the positioning requirements of workpieces of different specifications.

[0049] The receiving plate 104 can intercept the workpiece to make it dock precisely, so that the manipulator 2 can clamp the workpiece through the jaw mechanism 3. Among them, the drive module 303 provided at the end of the drive arm 301 acts, and the symmetric clamping jaw teeth 304 are mirror-closed to clamp the workpiece and pick it up. Subsequently, the manipulator 2 transfers the workpiece to the coding workbench 4, and the laser coding machine 5 identifies the workpiece position and features through the vision detection module 501, and automatically adjusts the laser parameters to complete precise coding.

[0050] After the coding is completed, the manipulator 2 places the workpiece on the turnover and temporary storage table 6. At this time, the infrared detection module 601 monitors the temporary storage state of the workpiece in real time and feeds back the signal to the central controller in the central control box 7. The controller triggers the manipulator 2 to flip the jaw mechanism 3, and makes the manipulator 2 pick up the workpiece again for secondary loading. During the whole process, the central controller synchronously coordinates the path planning of the manipulator 2 (avoiding interference between the jaws and the loading area), the start and stop of the laser coding machine 5, the opening and closing of the conveyor belt 102, and the signal processing of the detection module, realizing full-process automatic control, significantly improving the production efficiency and coding accuracy, and at the same time reducing the risk of manual intervention and fatigue.

[0051] The present invention covers any alternatives, modifications, equivalent methods, and solutions made within the spirit and scope of the present invention. For the public to have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention. However, those skilled in the art can fully understand the present invention without such detailed descriptions. Additionally, well-known methods, processes, procedures, components, and circuits, etc., are not described in detail to avoid unnecessary confusion with the essence of the present invention.

[0052] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as within the protection scope of the present invention.
