In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0035] The present embodiment provides a compression molding production equipment, which includes a compression molding production line. The compression molding production line is used to compression mold a composite material preform to obtain a composite material product.

[0036] See also Figure 1 and Figure 2 In this embodiment, the compression molding production line includes a first conveyor line 1, a glue coating machine 2, a molding press 3 and a cooling press 4, wherein the first conveyor line 1 is configured to convey the composite material preform, the glue coating machine 2 is arranged on the downstream side of the first conveyor line 1, the glue coating machine 2 is configured to apply glue to the composite material preform, the molding press 3 is configured to solidify the glue, and the cooling press 4 is configured to cool and shape the composite material preform.

[0037] Specifically, the molding press 3 automatically opens and closes the mold and provides a preset pressure, so that the composite material preform can be moved into the molding press 3 and the curing operation can be carried out. A high temperature and high pressure environment can be formed in the mold cavity of the molding press 3. After the preset holding time, the rubber is cured. Then, the molding press 3 automatically opens the mold, and the composite material preform that has completed the curing operation can be taken out from the molding press 3. The cooling press 4 automatically opens and closes the mold and provides a preset pressure, so that the composite material preform that has completed the curing operation can be moved into the cooling press 4 and the cooling and shaping operation can be carried out. After the preset holding time, the composite material preform completes cooling and shaping. Then, the cooling press 4 automatically opens the mold, and the composite material preform can be taken out from the cooling press 4. After the glue coating operation, curing operation and cooling and molding operation, the composite material preform is processed into a composite material product.

[0038] It is understandable that, since the specific structures of the forming press 3 and the cooling press 4 are both prior arts, they will not be described in detail in this embodiment.

[0039] Based on the above, the compression molding production line also includes a transport device 5, which is configured to transport the composite material preform from the first conveyor line 1 to the molding press 3, and to transport the composite material preform from the molding press 3 to the cooling press 4, that is, the transport device 5 can transport the composite material preform on the first conveyor line 1 to the molding press 3 for curing operation. In addition, the transport device 5 can also transport the composite material preform that has completed the curing operation from the molding press 3 to the cooling press 4 for cooling and molding operation.

[0040] In addition to the first conveyor line 1, the glue coating machine 2, the molding press 3, the cooling press 4 and the handling device 5, the compression molding production line also includes a waste collection box 6. The handling device 5 can transport the composite material preforms to be cured and / or the composite material preforms to be cooled and formed into the waste collection box 6, and the waste collection box 6 is filled with water.

[0041] Based on the above, when the molding press 3 stops due to a malfunction or other reasons, if the molding press 3 stops for a longer period of time than the preset time, the handling device 5 will throw the composite material preform that has completed the gluing operation and is to be cured into the waste collection box 6. Since the waste collection box 6 is filled with water, the water can isolate the air to prevent the glue from producing thick smoke due to chemical reactions, thereby avoiding affecting the production environment and eliminating the harm caused to the workers by the thick smoke. Similarly, when the cooling press 4 stops due to a malfunction or other reasons, if the cooling press 4 stops for a longer period of time than the preset time, the handling device 5 will throw the composite material preform that has completed the curing operation and is to be cooled and finalized into the waste collection box 6. Since the waste collection box 6 is filled with water, the water can isolate the air to prevent the glue from producing thick smoke due to chemical reactions, thereby avoiding affecting the production environment and eliminating the harm caused to the workers by the thick smoke. Correspondingly, when the molding press 3 and the cooling press 4 are shut down due to a malfunction or other reasons, if the shutdown time of the molding press 3 and the cooling press 4 exceeds the preset time, the conveying device 5 will throw the composite material preforms to be cured and the composite material preforms to be cooled and formed into the waste collection box 6. Since the waste collection box 6 is filled with water, the water can isolate the air to prevent the rubber from producing thick smoke due to chemical reactions, thereby avoiding affecting the production environment and eliminating the harm to the workers caused by the thick smoke.

[0042] It is understandable that the preset time is set by the staff according to the actual situation, and this embodiment does not impose any specific restrictions on this.

[0043] Based on the above, the compression molding production line is provided with a waste collection box 6. When the molding press 3 and / or the cooling press 4 is shut down for a long time due to a malfunction or the like, the handling device 5 can throw the composite material preforms to be cooled and formed and / or the composite material preforms to be cooled and formed into the waste collection box 6 filled with water, thereby avoiding the generation of thick smoke due to chemical reactions of the rubber, thereby avoiding affecting the production environment and eliminating the harm to the workers caused by the thick smoke.

[0044] In addition, the compression molding production equipment is provided with a waste collection box 6 filled with water, so as to avoid the generation of thick smoke due to chemical reaction of the rubber during the production process, thereby avoiding affecting the production environment and eliminating the harm caused to the workers by the thick smoke.

[0045] In addition to the first conveyor line 1 and the second conveyor line 7, the compression molding production line also includes a second conveyor line 7, and the transport device 5 is also configured to transport the composite material preform from the cooling press 4 to the second conveyor line 7, so as to unload the produced composite material products.

[0046] In this embodiment, the second conveyor line 7 is arranged in parallel with the first conveyor line 1, thereby saving the occupied space of the compression molding production line.

[0047] It can be understood that both the first conveyor line 1 and the second conveyor line 7 can be selected as belt conveyors or chain conveyors, etc., and there is no specific limitation on this in the present embodiment.

[0048] It is worth noting that compression molding includes not only wet molding but also high-pressure molding. The difference between high-pressure molding and wet molding is that the composite material preform is not coated with glue before being placed in the molding press 3, and the gluing operation is carried out in the mold cavity of the molding press 3. Specifically, when the composite material preform is placed in the molding press 3 and the molding press 3 is closed, the glue is injected into the mold cavity of the molding press 3 and the glue is cured under high temperature and high pressure.

[0049] Based on the above, the compression molding production line of this embodiment also includes a glue injection machine 8, which is configured to inject glue into the mold cavity of the molding press 3, that is, the compression molding production line is compatible with both wet molding and high-pressure molding. Specifically, if the composite material preform needs to be wet molded, the glue coating machine 2 coats the composite material preform located on the first conveyor line 1 with glue, and then moves the composite material preform coated with glue into the molding press 3. If the composite material preform needs to be high-pressure molded, the composite material preform is directly transported from the first conveyor line 1 to the molding press 3 by the transport device 5, and then the glue injection machine 8 injects glue into the mold cavity of the molding press 3, and cures the glue under high temperature and high pressure environment.

[0050] It is understandable that, for high pressure molding, the handling device 5 throws the composite material preforms to be cooled and formed into the waste collection box 6 only when the cooling press 4 stops for a long time due to a malfunction or other reasons.

[0051] It is worth noting that, since the specific structure and working principle of the glue injection machine 8 are all prior art, they will not be described in detail in this embodiment.

[0052] Based on the above, the glue coating machine 2 includes a first transfer module 21 and a glue coating head 22. The first transfer module 21 is configured to drive the glue coating head 22 to move, so as to automatically coat the composite material preform with glue, thereby improving production efficiency.

[0053] It is understandable that the first transfer module 21 may be selected as a driving structure such as a robot or a three-axis motion platform, and this is not specifically limited in the present embodiment.

[0054] Furthermore, the conveying device 5 includes a first conveying mechanism 51 and a second conveying mechanism 52. The first conveying mechanism 51 is arranged on the downstream side of the first conveyor line 1, and the first conveying mechanism 51 is configured to convey the composite material preform from the first conveyor line 1 to the molding press 3. In addition, the first conveying mechanism 51 can also convey the composite material preform that has completed the gluing operation and is waiting for the curing operation to the waste collection box 6, while the second conveying mechanism 52 is arranged between the molding press 3 and the cooling press 4. The second conveying mechanism 52 is configured to convey the composite material preform from the molding press 3 to the cooling press 4. In addition, the second conveying mechanism 52 can also convey the composite material preform that has completed the curing operation and is waiting for the cooling and shaping operation to the waste collection box 6.

[0055] Based on the above, the first conveying mechanism 51 and the second conveying mechanism 52 work independently and do not interfere with each other, thereby saving the time spent on conveying the composite material preform from the first conveyor line 1 to the molding press 3 and conveying the composite material preform from the molding press 3 to the cooling press 4, thereby further improving production efficiency.

[0056] Exemplarily, after the first conveying mechanism 51 conveys the previous composite material preform from the first conveyor line 1 to the molding press 3 for curing operation, the first conveying mechanism 51 can return to the first conveyor line 1 to move the next composite material preform. After the previous composite material preform completes the curing operation, the second conveying mechanism 52 conveys the composite material preform from the molding press 3 to the cooling press 4. At this time, the first conveying mechanism 51 can directly place the next composite material preform into the molding press 3.

[0057] Furthermore, the first conveying mechanism 51 includes a second transfer module 511 and a handling member 512. The second transfer module 511 is configured to drive the handling member 512 to move. The handling member 512 is configured to carry or release the composite material preform. The first conveying mechanism 51 can automatically carry the composite material preform, thereby further improving production efficiency.

[0058] It is understandable that the second transfer module 511 may be selected as a driving structure such as a robot or a three-axis motion platform, and this is not specifically limited in the present embodiment.

[0059] It is worth noting that the specific structure of the second transport mechanism 52 is the same as that of the first transport mechanism 51 , and therefore, the specific structure of the second transport mechanism 52 will not be described in detail in this embodiment.

[0060] Based on the above, the handling member 512 includes a mounting frame 5121 and a needle puncture suction cup 5122, the needle puncture suction cup 5122 is mounted on the mounting frame 5121, and the second transfer module 511 can drive the mounting frame 5121 to move, thereby transporting the composite material preform. This embodiment can prevent the composite material preform from falling during the process of transporting the composite material preform.

[0061] Furthermore, a plurality of needle puncture suction cups 5122 are installed on the mounting frame 5121, thereby further ensuring that the handling member 512 can stably carry the composite material preform.

[0062] In addition, it should be noted that the compression molding production equipment includes more than two compression molding production lines as described above, thereby further improving production efficiency.

[0063] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
