Technical Field

[0001] The present invention relates to the technical field of material conveying, and in particular to a workpiece conveying device and a processing system. Background Art

[0002] In order to improve the processing efficiency during the material transportation process, multiple processing tables are required to work simultaneously to improve the processing efficiency of the processing device. When multiple processing tables work simultaneously, a manipulator is often used to move the workpieces to be processed in the storage bin to the processing table for processing, and the processed workpieces on the processing table are transferred to the finished product storage bin. The above work often requires the manipulator to reciprocate twice to move the processed workpieces on the processing table away respectively, and then move the workpieces to be processed to the processing table. The above manipulator must reciprocate twice to complete the above work, which seriously affects the working efficiency of the workpiece conveying device. Summary of the invention

[0003] Therefore, the present invention provides a workpiece conveying device and a processing system to solve the problem that the existing workpiece conveying device needs to reciprocate twice to replace the processed workpiece on the processing table with an unprocessed workpiece, resulting in low working efficiency of the existing workpiece conveying device.

[0008] The workpiece conveying device further includes: a second guide rail arranged perpendicular to the first guide rail, and the sliding seat is driven to slide on the second guide rail.

[0009] The second guide rail is connected with the first guide rail and is driven to slide along the length direction of the first guide rail; the sliding seat is connected with the second guide rail and is driven to slide along the length direction of the second guide rail.

[0010] The plurality of workpiece processing tables are arranged in two opposite rows along a straight line; the first guide rail and the second guide rail are both arranged between the two rows of workpiece processing tables.

[0011] There are two first guide rails, which are respectively arranged opposite to the two rows of workpiece processing tables; two ends of the second guide rail are respectively slidably connected to the two first guide rails.

[0012] The workpiece conveying device further comprises:

[0013] The second guide rail driving mechanism includes: two threaded screws respectively arranged in the length direction of the two first guide rails, a rotating nut arranged on the second guide rail and connected to the threaded screw for transmission, a transmission belt that drives the two threaded screws to transmit synchronously, and a second driving source that drives the transmission belt to rotate.

[0014] The sliding seat comprises a U-shaped connecting plate with an opening along the rotation direction of the workpiece transfer arm; the workpiece transfer arm is rotatably arranged in the U-shaped connecting plate through a driving shaft driven by a first driving source.

[0015] The first clamp and / or the second clamp are arranged at the free end of the workpiece transfer arm.

[0019] The workpiece processing platform is used for processing the resonant cavity of the filter; the workpiece processing platform comprises a side wall processing mechanism for grinding the side wall of the resonant cavity, and a cavity bottom processing mechanism for grinding the cavity bottom of the resonant cavity.

[0020] The technical solution of the present invention has the following advantages:

[0021] 1. The workpiece conveying device provided by the present invention includes: a first guide rail, which is arranged along the positions of multiple workpiece processing tables; a sliding seat, which is driven to slide on the first guide rail; a workpiece transfer arm, which has a rotating end and a free end rotating around the rotating end; the rotating end is driven to rotate on the sliding seat; a workpiece transfer mechanism, which includes: a first clamp and a second clamp, the first clamp is used to transfer unprocessed workpieces, and the second clamp is used to transfer processed workpieces.

[0022] By simultaneously arranging a first clamp for transferring an unprocessed workpiece and a second clamp for transferring a processed workpiece on the workpiece transfer arm, the workpiece transfer arm can simultaneously transfer the processed workpiece on the processing table and move the workpiece to be processed to the processing table during the movement. In order to achieve the above functions, the workpiece transfer arm can adjust its position so that the workpiece on the workpiece processing table located at a position can be transferred and processed by the first clamp and the second clamp respectively. The present invention arranges a first guide rail along the arrangement direction of multiple workpiece processing tables, and the workpiece transfer arm is rotatably arranged on a sliding seat sliding on the above-mentioned first guide rail. Therefore, the workpiece transfer arm can be moved to the corresponding workpiece processing table position through the first guide rail, and the workpiece transfer arm is rotated by a corresponding angle, so that the first clamp and the second clamp on the workpiece transfer arm can be moved to the position of the workpiece processing table respectively, so that the first clamp and the second clamp can both place and transfer the workpiece to the same position. Through the above structure, the workpiece transfer arm can move once to simultaneously complete the work of transferring the processed workpiece on the processing table and moving the workpiece to be processed to the processing table, thereby greatly improving the working efficiency of the workpiece conveying device.

[0023] 2. The workpiece conveying device provided by the present invention further includes: a second guide rail arranged perpendicular to the first guide rail, and the sliding seat is driven to slide on the second guide rail.

[0024] By simultaneously arranging a second guide rail perpendicular to the first guide rail in the arrangement direction of the workpiece processing table, the sliding seat can be moved toward and away from the workpiece processing table through the second guide rail, thereby greatly increasing the flexibility of the workpiece transfer arm, so that when the workpiece transfer arm switches the first clamp and the second clamp to pick up and place the workpiece on the workpiece processing table, the first clamp and the second clamp can be changed in position by simply driving the workpiece transfer arm to slide along the second guide rail to complete the work of replacing the workpiece. In addition, by setting the second guide rail, a workpiece transfer arm can also simultaneously transfer workpieces on at least two rows of relatively parallel workpiece processing tables, thereby improving the utilization rate of the workpiece transfer arm.

[0025] 3. In the workpiece conveying device provided by the present invention, the plurality of workpiece processing tables are arranged in two opposite rows along a straight line; the first guide rail and the second guide rail are both arranged between the two rows of workpiece processing tables.

[0026] By arranging multiple workpiece processing tables in two opposite rows along a straight line, and arranging the first guide rail and the second guide rail between the two rows of workpiece processing tables, the workpiece transfer arm can move within the space surrounded by the workpiece processing tables to reduce the moving distance of the workpiece transfer arm, thereby improving the working efficiency of the workpiece conveying device.

[0027] 4. The workpiece conveying device provided by the present invention has two first guide rails, which are respectively arranged opposite to the two rows of workpiece processing tables; the two ends of the second guide rail are respectively connected to the two first guide rails in a sliding manner. The workpiece conveying device also includes: a second guide rail driving mechanism, including: two threaded screws respectively arranged in the length direction of the two first guide rails, a rotating nut arranged on the second guide rail and connected to the threaded screw in a transmission manner, a transmission belt that drives the two threaded screws to transmit synchronously, and a second driving source that drives the transmission belt to rotate.

[0028] By arranging a first guide rail beside each row of workpiece processing tables, the movement stability of the workpiece transfer arm can be effectively improved. In addition, by driving the sliding seat to move back and forth through the threaded screw structure, and driving each threaded screw to rotate through the transmission belt, each threaded screw can be effectively ensured to rotate synchronously, thereby ensuring that the sliding seat moves back and forth stably, avoiding the problem of position offset of the sliding seat during movement due to different rotation speeds of the threaded screws.

[0050] Workpiece transfer arm 4, such as Figure 3 and Figure 5As shown, the workpiece transfer arm 4 has a rotating end 5 and a free end 6 rotating around the rotating end 5; the rotating end 5 is driven and rotatably arranged on the sliding seat 3; a first clamp 8 for transferring an unprocessed workpiece 10 and a second clamp 9 for transferring a processed workpiece 10 are simultaneously arranged on the workpiece transfer arm 4; so that the workpiece transfer arm 4 can simultaneously transfer the processed workpiece on the processing table away during the movement, and move the workpiece to be processed to the processing table;

[0051] The workpiece transfer mechanism 7 is arranged at the position of the rotating end 5, and comprises: a first clamp 8 and a second clamp 9, wherein the first clamp 8 is used to transfer an unprocessed workpiece 10, and the second clamp 9 is used to transfer a processed workpiece 10; the first clamp 8 and the second clamp 9 reciprocate toward the workpiece 10 driven by the pneumatic push rod, so as to pick up or place the workpiece 10;

Therefore, the workpiece transfer arm 4 can interchange the positions of the empty container, the container filled with processed workpieces, and the container filled with unprocessed workpieces. The functions that the workpiece transfer arm 4 can realize are further increased.

[0053] In this embodiment, if Figure 1 As shown, the plurality of workpiece processing tables 2 are arranged in two opposite rows along a straight line; the first guide rail 1 and the second guide rail 11 are arranged between the two rows of workpiece processing tables 2. There are two first guide rails 1, which are respectively arranged opposite to the two rows of workpiece processing tables 2; the two ends of the second guide rail 11 are respectively connected to the two first guide rails 1 in a sliding manner.

In addition, the sliding seat 3 is driven to move back and forth by the threaded screw structure, and each threaded screw 20 is driven to rotate by the transmission belt 12, which can effectively ensure that each threaded screw 20 rotates synchronously, thereby ensuring that the sliding seat 3 moves back and forth stably, avoiding the problem of position offset of the sliding seat 3 during movement due to different rotation speeds of the threaded screw 20.

[0054] Of course, this embodiment does not specifically limit whether to set the second guide rail 11.
