[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] like Figures 1 to 7 As shown, this utility model provides a workpiece transfer device, which includes a frame 1, a loading rack 2, and a transfer fixture 3. The frame 1 includes a frame body 11 and a worktable 12 disposed on its top. The worktable 12 has a transfer channel 13 extending through it along its height direction. The transfer channel 13 extends along a first direction. The loading rack 2 is disposed on the worktable 12 and is located at one end of the worktable 12 in the first direction. The loading rack 2 has a loading channel 21 extending through it along its height direction. The loading channel 21 and the transfer channel 13 are vertically corresponding. The transfer fixture 3 includes a transfer gripper 31, which is movably disposed within the transfer channel 13. The frame body 11 is provided with a translation mechanism 32. The moving end of the translation mechanism 32 is movably disposed along the first direction. The moving end of the translation mechanism 32 is provided with a lifting mechanism 33. The transfer gripper 31 is disposed on the lifting mechanism 33.

[0021] The frame 11 has a frame structure, with the worktable 12 positioned on top of it for support. The transfer gripper 31 holds the workpiece 100 and is driven to move and lift via a translation mechanism 32 and a lifting mechanism 33, thus stably transferring the workpiece 100 from one workstation to another. The transfer channel 13 provides a movement path for the transfer gripper and also serves as a guide, reducing costs and ensuring the positional accuracy of the workpiece 100 during transfer. Furthermore, the workpiece 100 is movably mounted on the worktable 12, while the translation mechanism 32 and lifting mechanism 33 are both located on the frame 11 below the worktable 12, ensuring the overall center of gravity of the device is in the lower region, guaranteeing the stability of the device and thus ensuring the stability and accuracy of the workpiece 100 transfer.

[0022] In some embodiments, the transfer gripper 31 includes any component capable of clamping the workpiece 100, including a negative pressure suction cup, jaws, pneumatic grippers, etc. In this embodiment, the transfer gripper 31 includes a first gripping arm 311 and a second gripping arm 312 spaced apart along the first direction. The opposing sides of the first gripping arm 311 and the second gripping arm 312 are respectively a first side clamping surface 313 and a second side clamping surface 314. The opposing sides of the first side clamping surface 313 and the second side clamping surface 314 are respectively provided with a first bottom support surface 315 and a second bottom support surface 316. The first bottom support surface 315 and the second bottom support surface 316 respectively support the bottom of opposite sides of the workpiece 100. The first side clamping surface 313 and the second side clamping surface 314 are parallel to each other and are used to clamp the opposite sides of the workpiece 100. The distance between the first side clamping surface 313 and the second side clamping surface 314 is adjustable, thereby achieving stable clamping and fixing of the workpiece 100 and releasing the workpiece 100.

[0023] Optionally, flexible elements may also be provided on both the first clamping surface 313 and the second clamping surface 314. The flexible elements ensure a flexible clamping force on the workpiece 100, thus avoiding damage to the workpiece 100 during clamping. The flexible elements may include silicone, rubber, or sponge, etc.

[0024] In addition, when the bottom of the workpiece 100 has a groove, the transfer gripper 31 can also be provided with a protrusion at the corresponding position of the groove of the workpiece 100. The clamping and fixing effect of the transfer gripper 31 on the workpiece 100 can be further improved by the insertion and cooperation of the protrusion and the groove.

[0025] The translation mechanism 32 drives the transfer gripper 31 to reciprocate along the first direction, and the lifting mechanism 33 drives the lifting action of the transfer gripper 31. The translation mechanism 32 and the lifting mechanism 33 can be any driveable component, such as a cylinder, hydraulic cylinder, or lead screw drive, and can be adapted to different applications. For example, a lead screw drive is used when high-precision adjustment is required; a cylinder is used when coarse adjustment is required; this embodiment does not elaborate on or limit these aspects.

[0026] In some embodiments, the transfer channel 13 extends along a first direction, and the loading rack 2 is disposed on the worktable 12 and located at one end of the worktable 12 in the first direction. Thus, the workpiece 100 enters from one end of the transfer channel 13. In the extension direction of the transfer channel, the worktable 12 can be provided with multiple working stations. The workpiece 100 is transferred to different workpieces 100 by the transfer gripper 31 for corresponding operations, which realizes transfer while reducing costs.

[0027] In some embodiments, the loading channel 21 includes a wide channel 211 and a narrow channel 212 that are vertically connected. The bottom of the wide channel 211 is used to support the workpiece 100, and the narrow channel 212 is vertically aligned with the transfer channel 13. The bottom of the wide channel 211 is used to carry the workpiece 100, while the narrow channel 212 is vertically aligned with the transfer channel 13 to allow the transfer gripper 31 to pass through and clamp the workpiece 100 in the wide channel 211, thereby ensuring the reliability and stability of the workpiece 100 loading position.

[0028] Optionally, the length of the narrow channel 212 in the second direction is greater than or equal to the length of the transfer channel 13 in the second direction, and less than the length of the wide channel 211 in the second direction, wherein the second direction is perpendicular to the first direction. The width of the narrow channel 212 matches the width of the transfer channel 13, ensuring the stable passage of the transfer gripper 31 and avoiding interference when the transfer gripper 31 is holding the workpiece 100 or transferring the workpiece 100.

[0029] Optionally, the narrow channel 212 is located in the middle of the wide channel 211 in the second direction, thereby ensuring that the force exerted by the transfer gripper 31 on the workpiece 100 is located in the middle of the side of the workpiece 100, thus ensuring the stability of clamping and transfer and preventing the workpiece 100 from falling off.

[0030] In some embodiments, the wide channel 211 is provided with a stop 22 at at least one end in the first direction. The stop 22 and the material transfer channel 13 are provided with a through hole 221. The through hole 221 ensures the stable passage of the transfer gripper 31. The stop 22 blocks the movement of the workpiece 100, thereby ensuring the consistency of the workpiece 100 loading position and improving the efficiency of the transfer gripper 31 in positioning the workpiece 100.

[0031] like Figures 1 to 7 As shown, in some embodiments, the workpiece transfer device further includes a positioning mechanism 4, which includes a positioning element 41 and a positioning drive component 42. The positioning drive component 42 is used to drive the positioning element 41 to move along the first direction within the wide channel 211. By driving the positioning element 41 to reciprocate, the positioning element 41 and the stop block 22 respectively abut against the opposite sides of the workpiece 100, thereby limiting and fixing the workpiece 100 on the loading rack 2, thus ensuring the stability of the workpiece 100's position and facilitating subsequent clamping of the workpiece 100.

[0032] The positioning drive component 42 includes any component that can drive the positioning element 41 to move, such as a cylinder, hydraulic cylinder, or lead screw drive. Optionally, the positioning drive component 42 adopts a positioning cylinder.

[0033] Optionally, the positioning member 41 has a positioning end, and a clearance groove 411 is formed through the middle of the positioning end. The transfer gripper 31 is movably disposed within the clearance groove 411. The transfer gripper 31 passes through the clearance groove 411 during lifting and lowering, thereby avoiding interference with the positioning member 41.

[0034] Optionally, the stop block 22 is connected to the bottom of the wide channel 211 by a rounded corner transition. When the workpiece 100 is limited and fixed in the wide channel 211, the rounded corner can avoid the edge of the workpiece 100, thus preventing the workpiece 100 or the device from being damaged by sharp corner collision, thereby extending the service life of the workpiece 100 and the device.

[0035] In summary, this application provides a workpiece transfer device. The transfer gripper 31 holds the workpiece 100 and is driven to rise and move via a translation mechanism 32 and a lifting mechanism 33, thereby stably transferring the workpiece 100 from one workstation to another. The transfer channel 13 provides a movement path for the transfer gripper and also serves as a guide, reducing costs and ensuring the positional accuracy of the workpiece 100 during transfer. Furthermore, the workpiece 100 is movably mounted on the worktable 12, and both the translation mechanism 32 and the lifting mechanism 33 are mounted on the frame 11 below the worktable 12, ensuring the overall center of gravity of the device is located in the lower region, guaranteeing the overall stability of the device, and thus ensuring the stability and accuracy of the workpiece 100 transfer.

[0036] When transferring workpiece 100, the positioning drive component 42 drives the positioning component 41 to move, thereby limiting and fixing workpiece 100 inside the positioning component 41 and the stop block 22. Then, the lifting mechanism 33 drives the transfer gripper 31 to rise. The transfer gripper 31 passes through the clearance groove 411 and the through hole 221 until it is located on opposite sides of workpiece 100. Then, the transfer gripper 31 clamps workpiece 100. After that, the transfer gripper 31 is driven to continue rising, transferring workpiece 100 from the loading rack 2. Then, the translation mechanism 32 drives the transfer gripper 31 to move along the first direction to the next station, and the lifting mechanism 33 drives the transfer gripper 31 to descend, thereby placing workpiece 100 on the worktable 12, or placing workpiece 100 in the fixture of the next station, etc., for subsequent operations.

[0037] like Figures 1 to 7 As shown, this utility model also provides a production line, including the workpiece transfer device described above.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
