Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, and particularly relates to an automatic device for efficiently and accurately marking the surface of an outer-circle metal connector. Background Technique

[0002] In the traditional operation method of marking the surface of an outer-circle metal connector, there are many drawbacks in hand-rolling a hard die for engraving. First of all, whenever different products need to be marked, the hard die steel stamp must be replaced. This process is not only cumbersome but also very time-consuming. Workers need to spend a lot of time disassembling and installing different hard die steel stamps, which seriously affects production efficiency.

[0003] Secondly, the operation method of manually picking and placing parts is inefficient. The operator needs to pick up and place the outer-circle metal connectors one by one. This process is repetitive and time-consuming, greatly limiting the production speed. At the same time, there is also a safety hazard of being pinched in manual operation. Once the operator is not careful, it is easy to be pinched by the parts, posing a threat to personal safety.

[0004] Furthermore, the method of marking with a hard die engraving is prone to burr adhesion. During the engraving process, some burrs will be generated, and these burrs may adhere to the engraving part, resulting in unclear engraving. In order to ensure the quality of the marking, the burrs need to be cleaned frequently, which not only increases the workload but also greatly reduces the stability of the product.

[0005] In summary, the traditional method of marking the surface of an outer-circle metal connector can no longer meet the needs of modern production. Therefore, an automatic device for efficiently and accurately marking the surface of an outer-circle metal connector is proposed. Content of the Utility Model

[0031] In one embodiment, specifically: the clamping mechanism 23 includes a frame 30, a clamping block 31, a synchronous electric cylinder 32, a clamping groove 33 and an anti-slip pad 34;

[0032] The middle parts on both sides of the upper surface of the frame 30 are fixedly connected to the lower surface of the connecting frame 22. Both sides of the inner side wall of the frame 30 are slidably connected with clamping blocks 31. The middle parts of both sides of the frame 30 are fixedly connected with synchronous electric cylinders 32.

Through the laser printer 35, it is convenient to accurately print on the surface of the outer circular metal connector according to the preset marking information, and the printing content of the laser printer 35 can be edited through the controller 29.

[0034] In one embodiment, specifically: One side of the mounting frame 24 close to the rear part of the laser printer 35 is provided with a push box 36. One side of the upper surface of the push box 36 close to the mounting frame 24 is fixedly connected with a limiting cylinder 37.

The middle part of the side of the push box 36 far away from the mounting frame 24 is fixedly connected with a push-pull electric cylinder 39. The output end of the push-pull electric cylinder 39 is fixedly connected to the center of the side of the push block 38 far away from the mounting frame 24. The input end of the push-pull electric cylinder 39 is electrically connected to the output end of the controller 29. By driving the push block 38 to slide in the push box 36 through the push-pull electric cylinder 39, the transfer fixture 26 that slides down to the bottom in the limiting cylinder 37 is pushed onto the conveyor 25.

[0035] In one embodiment, specifically: One side of the operation table 11 close to the rear part of the mounting frame 24 is provided with a vibrating bowl feeder 40. The input end of the vibrating bowl feeder 40 is electrically connected to the output end of the controller 29. Through the vibrating bowl feeder 40, the outer circular metal connectors are vibrated one by one and conveyed neatly, so as to be conveniently conveyed into the transfer fixture 26 at the starting position of the conveyor 25.

[0036] In one embodiment, specifically: first limiting grooves 41 are respectively formed in the middle of the inner front wall and the inner rear wall of the sliding groove 13, first limiting blocks 42 are fixedly connected to the middle of the front surface and the rear surface of the sliding block 14, and the outer side walls of the first limiting blocks 42 are slidably connected to the inner side walls of the first limiting grooves 41. By sliding the first limiting blocks 42 on the sliding block 14 inside the first limiting grooves 41, the first limiting grooves 41 are limited, thereby increasing the stability of the movement of the sliding block 14.

[0037] In one embodiment, specifically: second limiting grooves 43 are respectively formed in the middle of the inner front wall and the inner rear wall of the frame 30, second limiting blocks 44 are fixedly connected to the middle of the front surface and the rear surface of the clamping block 31, and the outer side walls of the second limiting blocks 44 are slidably connected to the inner side walls of the second limiting grooves 43. By sliding the second limiting blocks 44 on the clamping block 31 inside the second limiting grooves 43, the second limiting blocks 44 are limited, thereby increasing the stability of the movement of the clamping block 31.

[0038] In one embodiment, specifically: a jig blanking groove 45 is fixedly connected to the front surface of the mounting frame 24, and a connector blanking port 46 is formed in the front part of the upper surface of the operating table 11. The connector blanking port 46 facilitates the collection of the printed connectors.

[0039] When the utility model is working: after the controller 29 receives the start signal, it starts the whole device, including components such as the motor 17, the lifting electric cylinder 21, the conveyor 25, the synchronous electric cylinder 32, the laser printer 35, the push-pull electric cylinder 39 and the vibrating disk feeder 40. The push-pull electric cylinder 39 starts first, driving the push block 38 to slide in the push box 36, and pushing the transfer fixture 26 at the bottom of the limit cylinder 37 to the starting position on the conveyor 25. This starting position is preset so that the vibrating disk feeder 40 can directly convey the outer circle metal connector into the transfer fixture 26 for limit fixation. Then, the vibrating disk feeder 40 starts to work, vibrating and arranging the outer circle metal connectors one by one and conveying them into the transfer fixture 26 at the starting position of the conveyor 25. Since the transfer fixture 26 has been pushed to the starting position, the outer circle metal connector can be smoothly fed in and limitedly fixed. Then, the conveyor 25 starts to convey the transfer fixture 26 and the outer circle metal connector. When the sensing piece 28 on the transfer fixture 26 passes by the sensor 27 in the printing area, the sensor 27 detects the signal and sends it to the controller 29. After receiving the signal, the controller 29 controls the conveyor 25 to pause. At the same time, the laser printer 35 starts and precisely prints on the surface of the outer circle metal connector according to the preset marking information. After printing is completed, the conveyor 25 continues to convey the transfer fixture 26 and the outer circle metal connector after printing. When the sensing piece 28 on the transfer fixture 26 passes by the sensor 27 in the unloading area, the sensor 27 detects the signal and sends it to the controller 29. After receiving the signal, the controller 29 controls the conveyor 25 to pause, starts the motor 17 to drive the screw 15 to rotate. Since the screw 15 is threadedly connected to the screw hole 16 on the slider 14, the slider 14 moves horizontally in the chute 13. The slider 14 drives the U-shaped connecting frame 18, the mounting plate 19, the lifting electric cylinder 21, the connecting frame 22 and the clamping mechanism 23 to move above the outer circle metal connector. The lifting electric cylinder 21 starts, pushing the connecting frame 22 to slide downward in the U-shaped connecting frame 18. The connecting frame 22 drives the clamping mechanism 23 to descend. The synchronous electric cylinder 32 starts, pushing the clamping block 31 to slide in the frame 30. The clamping groove 33 on the clamping block 31 approaches the outer circle metal connector. The anti-slip pad 34 in the clamping groove 33 contacts and clamps the connector. The lifting electric cylinder 21 retracts, driving the clamping mechanism 23 and the clamped connector to rise. The motor 17 rotates in reverse, and the slider 14 drives the clamping mechanism 23 and the connector to move above the connector discharge port 46. The clamping mechanism 23 releases the clamping of the connector, so that the connector falls into the connector discharge port 46 by its own gravity for the next process.

[0040] As described above, it is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions thereof, and all of these should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claimed rights.
