TECHNICAL FIELD

[0001] The present application relates to the technical field of vulcanization devices, in particular to a vulcanization automation device. BACKGROUND

[0002] The vulcanization of raw rubber is a key process that promotes the chemical reaction between raw rubber and vulcanizing agents under specific conditions. During this process, the originally linear macromolecules gradually crosslink and transform into three-dimensional network macromolecules. This transformation is of great significance, as it can greatly optimize the performance of rubber, endowing it with high strength, high elasticity, high wear resistance, and excellent corrosion resistance, thereby significantly broadening the application scope of rubber. At present, the common vulcanization operation mode mainly relies on manual completion. Workers need to manually place the raw rubber sheets in sheet form into the vulcanization mold for vulcanization treatment, and then take them out after the vulcanization is completed. This process is quite cumbersome, as workers not only have to frequently transfer materials, but also face many potential risks during the entire vulcanization process. Since the vulcanization process may release toxic and harmful gases such as hydrogen sulfide, sulfur dioxide, volatile organic compounds, and ammonia, long-term exposure to such a working environment will undoubtedly cause harm to the health of workers. Therefore, a more automated vulcanization device can be designed. SUMMARY

Specifically, in use, the stacked raw rubber materials are placed on the operation table 10 by hand, then one raw rubber material is grabbed by the first mechanical arm 11 through the first grabbing device 12 and placed on the upper material preparation platform 22 (at this time, the upper material preparation platform 22 is directly above the lower material preparation platform 21), after the raw rubber material on the upper material preparation platform 22 is processed, the raw rubber material is grabbed by the first mechanical arm 11 through the first grabbing device 12, then the first driving device drives the sliding seat 23 to drive the upper material preparation platform 22 to move on the sliding rail 24, so that the lower material preparation platform 21 is exposed, at this time, the first mechanical arm 11 drives the first grabbing device 12 to place the raw rubber material on the lower material preparation platform 21, then the sliding seat 23 drives the upper material preparation platform 22 to return to directly above the lower material preparation platform 21, the first mechanical arm 11 regrabs a new raw rubber material and places it on the upper material preparation platform 22, after the raw rubber material is processed, the second mechanical arm 13 grabs the raw rubber materials on the upper material preparation platform 22 and the lower material preparation platform 21 through the second grabbing device 14 and transfers them to the vulcanization mold. In this way, the worker only needs to carry the raw rubber material to the operation table 10, and the subsequent operation can be automatically completed, so that the operation precision is higher and the labor intensity of the worker is smaller.

[0017] The first driving device in the embodiment comprises a linear motor 32 arranged on the sliding seat 23. Specifically, the linear motor 32 can drive the sliding seat 23 to drive the upper material preparation platform 22 to move reciprocally on the sliding rail 24. The linear motor 32 can also be replaced by a ball screw, a gear and rack, or other conventional driving structures.

[0018] The upper layer material preparation platform 22 in the embodiment is provided with a stripping device 30 on the upper side of one end close to the sliding seat 23; the upper layer material preparation platform 22 is used to place raw rubber materials, the raw rubber materials including raw rubber sheets and spacers which are adhered to each other, the raw rubber sheets and the spacers being connected through an adhesive, and the spacers being arranged above the raw rubber sheets; the stripping device 30 is used to strip the raw rubber sheets and the spacers. Specifically, the raw rubber sheets themselves have certain viscosity, so that the adjacent raw rubber sheets need to be separated by using the spacers when being stored, and the spacers need to be stripped off the raw rubber sheets before vulcanization, so that the raw rubber sheets and the spacers need to be separated by using the stripping device 30 after the raw rubber materials are placed on the upper layer material preparation platform 22, and the spacers need to be repeatedly used. Since only the upper layer material preparation platform 22 is provided with the stripping device 30, all the raw rubber materials need to be stripped on the upper layer material preparation platform 22 first.

[0019] The stripping device 30 in the embodiment includes a push rod 31 horizontally arranged on the upper layer material preparation platform 22, and a second driving device used to drive the push rod 31 to rotate; when the raw rubber materials are above the upper layer material preparation platform 22, the axial direction of the push rod 31 is perpendicular to the length direction of the sliding rail 24; the height of the axial direction of the push rod 31 is the same as the height of the upper surface of the raw rubber sheets. Specifically, the specific stripping operation is that after the first mechanical arm 11 uses the first grabbing device 12 to grab the raw rubber materials and makes them adhere to the upper layer material preparation platform 22, the first mechanical arm 11 slowly moves towards the push rod 31, at this time, the push rod 31 is in a rotating state under the action of the second driving device, when the raw rubber materials contact the push rod 31, the rotating push rod 31 directly enters between the raw rubber sheets and the spacers, and then enters between the raw rubber sheets and the spacers better through rotation, when the push rod 31 enters a certain distance on the raw rubber sheets, the rotation of the push rod 31 is stopped, at this time, the push rod 31 can press the raw rubber sheets, then the first grabbing device 12 grabs the spacers, and the spacers are torn off the raw rubber sheets (the raw rubber sheets and the spacers are soft structures, the torn-off spacers need to be stored in a separate position for subsequent repeated use), in this process, the first negative pressure hole 25 on the upper layer material preparation platform 22 can assist in sucking the raw rubber sheets, after the spacers are completely torn off, the push rod 31 is reversely rotated to push the raw rubber sheets out (at this time, the first negative pressure hole 25 stops generating negative pressure, and can blow a certain positive wind to slightly lift the raw rubber sheets, so that the raw rubber sheets can be more easily moved on the upper layer material preparation platform 22), so that the raw rubber sheets are completely separated from the push rod 31, and the second grabbing device 14 can take away the raw rubber sheets subsequently.

[0020] The both ends of the dialing rod 31 in the embodiment are rotationally connected with the upper layer material preparation platform 22; the driving device comprises a motor 32 arranged on the upper layer material preparation platform 22, a driving wheel arranged on the output shaft of the motor 32, a driven wheel arranged on one end of the dialing rod 31, and a transmission belt 33 used to connect the driving wheel and the driven wheel. Specifically, the motor 32 can drive the dialing rod 31 to rotate in two directions through the transmission belt 33, wherein the motor 32 can also drive the dialing rod 31 to rotate through a gear.

[0021] The first grabbing device 12 in the embodiment comprises a first support plate 121 connected with the movable end of the first mechanical arm 11, a plurality of suction pipes 122 arranged on the lower side of the first support plate 121, and a suction disc arranged on the lower end of the suction pipe 122; the suction pipe 122 is connected with a negative pressure device. Specifically, the raw rubber material can be sucked by the suction pipe 122 and the suction disc.

[0022] The second grabbing device 14 in the embodiment comprises a vertically arranged second support plate 141, a pair of negative pressure plates 142 arranged on one side of the second support plate 141, and a plurality of second negative pressure holes arranged on the negative pressure plate 142; the pair of negative pressure plates 142 are horizontally arranged, and one negative pressure plate 142 is arranged directly above the other negative pressure plate 142; the plurality of second negative pressure holes are connected with negative pressure devices; the vertical distance between the pair of negative pressure plates 142 is equal to the vertical distance between the upper layer material preparation platform 22 and the lower layer material preparation platform 21. Specifically, when the second grabbing device 14 grabs the raw rubber sheet, the second mechanical arm 13 drives the second support plate 141 to move to the upper layer material preparation platform 22 (at this time, the upper layer material preparation platform 22 is directly above the lower layer material preparation platform 21), one negative pressure plate 142 is directly above one raw rubber sheet, and the raw rubber sheet is sucked by the second negative pressure hole on the negative pressure plate 142, and then is transferred to the vulcanization mold. Among them, a plurality of raw rubber sheets can be placed on the upper layer material preparation platform 22 at the same time, and the second grabbing device 14 can also grab a plurality of raw rubber sheets at the same time.

[0023] The embodiment further comprises a storage plate 15 horizontally arranged on the operation table 10, and a telescopic cylinder 16 used to drive the storage plate 15 to ascend and descend; the storage plate 15 is arranged close to the lower layer material preparation platform 21. Specifically, the storage plate 15 is placed close to the lower layer material preparation platform 21, and the worker places the raw rubber material on the storage plate 15 when preparing materials, so that the first mechanical arm 11 can be conveniently grabbed.

[0024] In the embodiment, the image recognition device is arranged above the operation table 10 and vertically downward, and is arranged at one end of the slide rail 24 away from the lower layer material preparation platform 21. Specifically, when the rubber sheet is placed on the upper layer material preparation platform 22, the position may not be completely accurate, so the image recognition device can be used to identify the position of the rubber sheet, and then the first mechanical arm 11 is used to adjust the position. Since the rubber sheet is a regular square structure, its shape is easy to identify, and a conventional image recognition algorithm can be used.

[0025] In summary, in the use of the vulcanization automation device, the rubber materials stacked together are placed on the operation table 10 by manual operation, and then the first mechanical arm 11 is used to grab one rubber material through the first grabbing device 12, and then place it on the upper layer material preparation platform 22 (at this time, the upper layer material preparation platform 22 is directly above the lower layer material preparation platform 21). After the rubber material is processed on the upper layer material preparation platform 22, the first mechanical arm 11 is used to grab the rubber material through the first grabbing device 12, and then the first driving device drives the slide 23 to drive the upper layer material preparation platform 22 to move on the slide rail 24, so that the lower layer material preparation platform 21 is exposed. At this time, the first mechanical arm 11 drives the first grabbing device 12 to place the rubber material on the lower layer material preparation platform 21, and then the slide 23 drives the upper layer material preparation platform 22 to return to the lower layer material preparation platform 21 directly above. The first mechanical arm 11 regrabs the new rubber material and places it on the upper layer material preparation platform 22, and after processing the rubber material, the second mechanical arm 13 grabs the rubber material on the upper layer material preparation platform 22 and the lower layer material preparation platform 21 through the second grabbing device 14, and then transfers it to the vulcanization mold. In this way, the worker only needs to carry the rubber material to the operation table 10, and the subsequent operation can be automatically completed. Therefore, the operation precision is higher, and the labor intensity of the worker is smaller.

For those skilled in the art, the present application can have various changes and variations.
