Description

Technical Field

[0001] The utility model relates to the technical field of composite material production, in particular to a production line for composite material preforms. Background Art

[0002] Composite material preform refers to a semi-finished product with a certain shape and size made of fiber-reinforced resin-based composite materials, which is usually used to make various composite products.

[0003] In the prior art, composite preforms are generally prepared by automated production lines. Specifically, the production line is provided with a loading station and a pressing station. Several layers of composite sheets are stacked at the loading station. The composite sheets stacked at the loading station can be sent to the pressing station in batches for pressing. Specifically, in the prior art, composite sheets are generally transported by a conveying mechanism. The number of composite sheets taken by the conveying mechanism at one time is the number of composite sheets required for pressing a composite preform. In order to avoid the conveying mechanism from additionally sticking other composite sheets stacked below each time when conveying a preset number of layers of composite sheets, the prior art generally welds the composite sheets in batches in advance, that is, the prior art first welds several layers of composite sheets required for pressing a composite preform together to form a composite block, and then stacks several composite blocks obtained by welding together, so as to ensure that the conveying mechanism can only transport one composite block each time, that is, the number of composite sheets transported by the conveying mechanism each time is accurate, thereby ensuring that the composite preform obtained by subsequent pressing meets the requirements.

[0004] However, the method of ensuring the accuracy of the number of composite material sheets transported each time by welding will result in an additional step in the production process of the composite material preform, thereby reducing production efficiency.

[0005] Therefore, the above problems need to be solved urgently. Utility Model Content

It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention.

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

[0036] See also Figures 1 to 5 The present embodiment provides a production line for composite material preforms, which includes a loading platform 210, a press 220 and a first transport mechanism 230. A plurality of stacks 100 are stacked on the loading platform 210, and the stacks 100 include more than two layers of composite material sheets 110. Two adjacent stacks 100 are separated by a partition 211. The press 220 is configured to press the stacks 100 to form a composite material preform, and the first transport mechanism 230 is configured to transport the plurality of stacks 100 one by one to the press 220 for pressing.

[0037] Based on the above, in this embodiment, the number of composite sheets 110 included in a single stack 100 is the number of composite sheets 110 required for pressing to obtain a composite preform. In this embodiment, two adjacent stacks 100 are separated by a partition 211 to prevent the first conveying mechanism 230 from sticking to the composite sheet 110 located below the stack 100 when conveying the stack 100, thereby ensuring that the number of composite sheets 110 conveyed by the first conveying mechanism 230 each time is accurate, and further ensuring that the composite preform obtained by subsequent pressing meets the requirements. That is, the production line of composite preforms can ensure that the number of composite sheets 110 conveyed each time is accurate without setting a welding process, thereby simplifying the production process of composite preforms, and further improving production efficiency.

[0038] Specifically, the first conveying mechanism 230 conveys the upper one of the two adjacent stacks 100 to the press 220 for pressing. At this time, among all the materials stacked on the loading platform 210, the one located at the top is a partition 211. The first conveying mechanism 230 then takes out the top partition 211. After the press 220 completes the pressing operation, the pressed composite material preform is taken away from the press 220. After that, the first conveying mechanism 230 conveys the lower one of the two adjacent stacks 100 to the press 220 for pressing.

[0039] It should be noted that the material of the composite material sheet 110 is glass fiber, carbon fiber or aramid fiber, etc., which is not specifically limited in this embodiment.

[0040] In addition, it should be noted that since the specific structure and working principle of the press 220 are both existing technologies, this embodiment will not elaborate on them.

[0041] Based on the above, after all the stacks 100 on the loading platform 210 are moved away, the production line of composite material preforms supplies composite material sheets 110 to the loading platform 210 by manual loading. Moreover, each time the staff supplies a preset number of composite material sheets 110 to the loading platform 210, they supply a partition 211 to the loading platform 210. It can be understood that the preset number is the number of composite material sheets 110 included in a single stack 100, so that two adjacent stacks 100 can be separated by the partition 211. Of course, in other optional embodiments, composite material sheets 110 can also be supplied to the loading platform 210 by other methods such as robot loading, and this embodiment does not specifically limit this.

[0042] Furthermore, the production line of composite material preforms also includes a storage table (not shown in the figure), and the first transport mechanism 230 can transport the partition 211 to the storage table, so as to temporarily store the partition 211 on the storage table for next use.

[0043] In addition to the loading platform 210, the production line of the composite material preform also includes a unloading platform 240, which is configured to carry the pressed stack 100, that is, when the stack 100 is pressed, the pressed composite material preform can be temporarily stored on the unloading platform 240, so as to facilitate the unloading of several composite material preforms at one time.

[0044] Based on the above, in addition to the first conveying mechanism 230, the production line of the composite material preform also includes a second conveying mechanism 250. The second conveying mechanism 250 is configured to convey the pressed stack 100 to the unloading platform 240. That is, in this embodiment, the operation of conveying the stack 100 to the press 220 and the operation of conveying the composite material preform to the unloading platform 240 are respectively performed by the first conveying mechanism 230 and the second conveying mechanism 250. The two operations are performed independently and do not interfere with each other, thereby saving the time spent on completing the above two operations and further improving production efficiency.

[0045] For example, after the first conveying mechanism 230 conveys the previous stack 100 to the press 220 for pressing, the first conveying mechanism 230 can return to the loading platform 210 to take the next stack 100. After the pressing operation of the previous stack 100 is completed, the second conveying mechanism 250 conveys the pressed composite material preform to the unloading platform 240. At this time, the first conveying mechanism 230 can directly place the next stack 100 into the press 220.

[0046] Furthermore, the production line of the composite material preform includes at least two loading platforms 210. After all the stacked bodies 100 on one of the loading platforms 210 are taken away, the first transport mechanism 230 can be switched to another loading platform 210 to take materials, and the staff can replenish materials to the empty loading platform 210.

[0047] Based on the above, in this embodiment, it is possible to avoid the first transport mechanism 230 from shutting down due to the vacancy of the loading platform 210, thereby further improving production efficiency.

[0048] In this embodiment, the first conveying mechanism 230 includes a mounting frame 231 and a transfer module 232, wherein a needle suction cup 2311 is installed on the mounting frame 231, and the transfer module 232 is configured to move the mounting frame 231 so that the mounting frame 231 can move between the press 220 and the loading platform 210, so that the first conveying mechanism 230 can absorb all the composite material sheets 110 of the stack 100 at the loading platform 210 at one time through the needle suction cup 2311, and convey the stack 100 to the press 220.

[0049] It can be understood that in this embodiment, the transfer module 232 is a robot. Of course, in other optional embodiments, the transfer module 232 can also be other driving structures such as a three-axis mobile platform, and this embodiment does not make specific restrictions on this.

[0050] Furthermore, a plurality of needle suction cups 2311 are installed on the mounting frame 231 to ensure that the first conveying mechanism 230 can stably convey the stack 100 to the press 220 , that is, this embodiment can prevent the stack 100 from falling when the first conveying mechanism 230 conveys the stack 100 .

[0051] It is understandable that the specific structure and working principle of the acupuncture suction cup 2311 are all existing technologies, so they are not described in detail in this embodiment.

[0052] In addition, a position sensor 2312 is also installed on the mounting frame 231. Specifically, a first mounting block 2316 is fixedly connected to the mounting frame 231, and the position sensor 2312 is installed on the first mounting block 2316. The position sensor 2312 is configured to detect the relative position of the mounting frame 231 and the stacked body 100, thereby ensuring that the mounting frame 231 moves into position relative to the loading platform 210, that is, this embodiment can ensure that the needle puncture suction cup 2311 moves into position relative to the loading platform 210, thereby ensuring that the needle puncture suction cup 2311 can effectively absorb the stacked body 100.

[0053] It is understandable that the position sensor 2312 may be a photoelectric sensor or an ultrasonic sensor, etc., and this is not specifically limited in this embodiment.

[0054] Furthermore, a connecting rod 2313 is fixedly connected to the mounting frame 231, and the needle suction cup 2311 is fixedly connected to the connecting block 2314. The axis of the connecting rod 2313 is perpendicular to the adsorption surface of the needle suction cup 2311. The connecting block 2314 is movably connected to the connecting rod 2313 along the axial direction of the connecting rod 2313. A spring 2315 is sleeved on the outer periphery of the connecting rod 2313, and the spring 2315 abuts between the mounting frame 231 and the connecting block 2314. Specifically, a second mounting block 2317 is fixedly connected to the mounting frame 231, and the connecting rod 2313 is fixedly connected to the second mounting block 2317, and the spring 2315 abuts between the second mounting block 2317 and the connecting block 2314. When the needle suction cup 2311 contacts the composite material sheet 110, the connecting block 2314 moves along the axial direction of the connecting rod 2313 toward the side close to the mounting frame 231 and compresses the spring 2315. That is, in this embodiment, the needle suction cup 2311 is in flexible contact with the composite material sheet 110 , thereby avoiding damage to the composite material sheet 110 .

[0055] In addition, in the present embodiment, the mounting frame 231 is detachably connected to the transfer module 232 , so that the acupuncture suction cup 2311 and / or the position sensor 2312 can be maintained in a timely manner.

[0056] Exemplarily, a male connector 2318 is provided on the mounting frame 231. Based on the content mentioned above, the transfer module 232 is a robot, and a female connector (not shown in the figure) is provided at the end of the transfer module 232. That is, in this embodiment, the mounting frame 231 can be quickly disassembled and assembled through the male connector 2318 and the female connector.

[0057] Of course, in other optional embodiments, the mounting frame 231 may also be connected to the transfer module 232 by other detachable means such as bolt connection, and this is not specifically limited in the present embodiment.

[0058] In addition, it is worth noting that the specific structure of the second transport mechanism 250 is the same as that of the first transport mechanism 230 , and therefore, it will not be described in detail in this embodiment.

[0059] 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.
