Description

Technical Field

[0001] This utility model relates to the technical field of production line mechanisms, specifically a double rotary table series mechanism. Background Technology

[0002] In modern industrial production, the assembly of workpieces often requires multiple steps and precise positioning and operation. Traditional assembly methods, mostly relying on manual operation or simple mechanical devices, are not only inefficient but also struggle to guarantee assembly accuracy and consistency. With the development of automation technology, designing an efficient and precise automated assembly mechanism to meet the needs of large-scale production has become an urgent problem to be solved. Currently, some product assembly equipment on the market is generally arranged in a linear or circular production line. In actual assembly, when there are many product workstations, a linear production line layout requires a large amount of space, which is not conducive to workshop production operations. For a circular production line, the diameter of the disc needs to be increased to accommodate a sufficient number of production workstations. However, the length and width of the workshop are predetermined dimensions and cannot be expanded indefinitely. Therefore, how to solve the layout problem of production lines with numerous workstations but limited workshop space is a technical problem that urgently needs to be addressed in existing production line layouts. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a dual-turntable series mechanism, which enables the setup of multiple workstations through a dual-turntable design without requiring an expansion of the workshop area, thus reducing the investment of production capital.

[0004] A dual-rotor series mechanism, characterized in that it comprises:

[0005] The first step is to have N first carriers arranged at equal intervals around the circumference of the surface of the turntable. Each first carrier has a processing station on its outer ring. N is a natural number greater than or equal to 3.

[0006] The second step turntable has M second carriers arranged at equal intervals around its surface. Each second carrier has a corresponding processing station on its outer ring. M is a natural number greater than or equal to 3.

[0007] And the transfer module, which includes a single-axis robot module, a lifting mechanism, and a gripper mechanism;

[0008] The first and second stepping turntables are spaced apart and form a central connecting line. A transfer module is fixed between the first and second carriers corresponding to the two different stepping turntables located between the central connecting line. The position of the first carrier on one side of the transfer module is the first transfer station area, and the position of the second carrier on the other side of the transfer module is the second transfer station area. The lifting mechanism and the gripper mechanism transfer the product on the first carrier in the first transfer station area to the second carrier in the second transfer station area along the single-axis robot module.

[0009] Its further features are:

[0010] It also includes a base, the four sides of which are fixed to the ground by several columns, and a space is left between the base and the ground for the installation of a power source;

[0011] The center of the first step turntable is fitted onto the output shaft end of the first reducer via a positioning connecting sleeve. The input end of the first reducer is connected to the output end of the first step motor via a synchronous belt pulley structure. The first step motor is horizontally arranged on the corresponding lower surface of the base. The base has a clearance notch corresponding to the position of the synchronous belt pulley. The upper part of the synchronous belt of the synchronous belt pulley passes through the clearance notch and is synchronously connected to the input pulley of the first step turntable. The output shaft of the first reducer is perpendicular to its input shaft. The use of the first reducer ensures that the first step turntable can rotate at a set speed under the drive of the first step motor through the corresponding reduction ratio.

[0012] The lower part of the second stepping turntable is provided with a vertical mounting base, which is fixed to the upper surface of the base. The inner cavity area of ​​the vertical mounting base is provided with a second transmission mechanism. The second stepping motor is fixed to the lower surface of the base. The output end of the second stepping motor is connected to the input end of the second transmission mechanism. The output end of the second transmission mechanism is provided with a rotating disk. The lower convex shaft of the rotating disk is embedded in the inner ring of the second bearing of the vertical mounting base. The bottom of the second stepping turntable is coaxially fixed to the rotating disk, which enables the second stepping motor to reliably drive the second stepping turntable to rotate step by step.

[0013] The single-axis robot module includes a gantry support. The crossbeam of the gantry support covers the first transfer station area and the second transfer station area. The bottom of the column of the gantry support is fixed to the upper surface of the base. The single-axis robot module is mounted on the crossbeam. The output end of the single-axis robot module is equipped with the lifting mechanism. The lower output end of the lifting mechanism is fixed to the gripper mechanism. The gripper mechanism has its grippers facing downwards and is used to grip the product.

[0014] By adopting this utility model, the products to be assembled are continuously placed at the designated position of the input station of the first step turntable. The equipment is started, and the first step turntable and the second step turntable rotate according to the preset program. After the workpiece reaches the first transfer station area, the lifting mechanism and the gripper mechanism transfer the product located on the first carrier in the first transfer station area to the second carrier in the second transfer station area along the single-axis robot module. Then, the gripper mechanism quickly resets to the position above the first carrier in the first transfer station area to perform the next transfer operation. This allows multiple stations to be distributed into two sets of turntable station arrangements. Through the double turntable design, multiple sets of stations can be set up without expanding the workshop area, thus reducing the investment of production capital. Attached Figure Description

The lifting mechanism 70 and the gripper mechanism 80 transfer the product on the first carrier 40 in the first transfer station area 101 to the second carrier 50 in the second transfer station area 201 along the single-axis robot module 60.

[0026] In specific implementation, it also includes a base 90, the four sides of which are fixed to the ground by several columns 91, and a space for the installation of the power source is left between the base 90 and the ground;

[0027] The center of the first stepper turntable 10 is fitted onto the output shaft end of the first reducer 100 through a positioning connecting sleeve 11. The input end of the first reducer 100 is connected to the output end of the first stepper motor 120 through a synchronous pulley 110. The first stepper motor 120 is horizontally arranged on the corresponding lower surface of the base 90. The base 90 is provided with a clearance notch corresponding to the position of the synchronous pulley 110. The upper part of the synchronous belt of the synchronous pulley 110 passes through the clearance notch and is synchronously connected to the input pulley of the first stepper turntable 10. The output shaft of the first reducer 100 is set perpendicular to its input shaft. The use of the first reducer 100 ensures that the first stepper turntable 10 can rotate at a set speed under the drive of the first stepper motor 120 through the corresponding reduction ratio.

[0028] The lower part of the second stepping turntable 20 is provided with a vertical mounting base 130, which is fixedly mounted on the upper surface of the base 90. The inner cavity area of ​​the vertical mounting base 130 is provided with a second transmission mechanism 140. The second stepping motor 150 is fixedly mounted on the lower surface of the base 90.

The gripper of the gripper mechanism 80 is oriented downwards and is used to grip the product. In specific implementation, the lifting mechanism 70 is a lifting slide rail cylinder, and the gripper mechanism 80 is a pneumatic gripper mechanism.

[0030] In a specific embodiment, eight first carriers 40 are arranged at equal intervals around the circumference of the first step turntable 10, and four second carriers 50 are arranged at equal intervals around the circumference of the second step turntable 20. That is, the dual turntables can be set with a maximum of 12 processing stations. In actual process, processing stations can be set at the corresponding positions as needed.

[0031] Its working principle is as follows: The products to be assembled are continuously placed at the designated position of the input station of the first step turntable. The equipment is started, and the first step turntable and the second step turntable rotate according to the preset program. After the workpiece reaches the first transfer station area, the lifting mechanism and the gripper mechanism transfer the product located on the first carrier in the first transfer station area to the second carrier in the second transfer station area along the single-axis robot module. Then the gripper mechanism quickly resets to the position above the first carrier in the first transfer station area to perform the next transfer operation. This allows multiple stations to be distributed into two sets of turntable station arrangements. Through the design of the double turntable, multiple sets of stations can be set up without expanding the workshop area, thus reducing the investment of production capital.
