[0013] A process for integrally forming a carbon fiber workpiece containing a metal core comprises the following steps:

[0014] S1: Before preparing the carbon fiber workpiece, the upper mold and the lower mold used for preparation need to be clamped and fixed by two special-shaped mold clamping devices respectively, and the mold is placed between the two clamping parts. The driving motor is controlled to drive the driving screw to rotate, thereby driving one of the clamping parts connected to the driving block to move toward the other clamping part, thereby achieving the effect of controlling the two clamping parts to clamp and fix it from both sides of the mold. After clamping and fixing, the translation lifting assembly and the conveyor belt are controlled to drive the fixed upper mold and lower mold to move to the carbon fiber prepreg feeding device for prepreg attachment. Through the set translation lifting assembly, when it is necessary to control the movement of the upper mold, the translation plate can be driven to move in a straight line along the direction of the conveyor belt by controlling the first electric push rod to adjust the position of the upper mold to adapt to different processing procedures. The height of the upper mold can be adjusted by controlling the second electric push rod to achieve the docking of the upper mold and the lower mold.

[0015] S2: After the upper mold and the lower mold are fixed by the special-shaped mold clamping device, multiple layers of carbon fiber prepreg need to be attached to the inner walls of the upper mold and the lower mold, and the upper mold and the lower mold are transported to between the feeder and the first manipulator through the cooperation of the conveyor belt and the translation lifting assembly, and the first manipulator is controlled to take a certain amount of carbon fiber prepreg delivered by the feeder and attach it to the inner walls of the upper mold and the lower mold in turn.

[0016] S3: After the carbon fiber prepreg is attached to the inner wall of the upper mold and the lower mold, it is necessary to attach multiple layers of anti-permeability layers to the inside of the upper mold and the lower mold, and attach multiple layers of foaming materials to the outside of the anti-permeability layers. Since the anti-permeability layer or foaming material is rolled on the winder, it needs to be cut into corresponding lengths before attaching the anti-permeability layer. And since there may be wrinkles on its surface, it needs to be flattened to a flat state to facilitate subsequent attachment. First, one end of the anti-permeability layer rolled on the winder is pulled out by the second manipulator and laid flat on the operating table. The flattening drum moves upward and passes under the flattening drum and the cutting blade. The third electric push rod drives the flattening drum to descend and make it contact with the upper surface of the anti-permeation layer. In the process of pulling the anti-permeation layer, the flattening drum continues to rotate on its surface to flatten it. After pulling it to the required length, the cutting blade is controlled to descend to contact with the surface of the anti-permeation layer and move from one end to the other end under the cooperation of the driving electric cylinder and the fourth electric push rod, so as to realize the cutting work on it. Then the second manipulator is controlled to take the cut anti-permeation layer to the outside of the prepreg layer on the inner wall of the upper mold or the lower mold.

[0017] S4: After the prepreg layer and the anti-permeation layer of the upper mold and the lower mold are attached, the first manipulator is controlled to grab the metal core on the placement table and move it to the carbon fiber prepreg feeding device and the anti-permeation layer attaching device in sequence to attach the prepreg layer and the anti-permeation layer to its surface.

[0018] S5: Then, the metal core is placed inside the lower mold by the first robot, and then a single-sided foaming material layer of corresponding thickness is attached to the outer side of the anti-permeation layer of the upper mold and the lower mold by the foaming material attaching device according to the size of the workpiece.

[0019] S6: After the prepreg layer, anti-permeability layer and foaming material layer of the upper mold and the lower mold are attached, and the metal core is placed inside the lower mold, the upper mold and the lower mold are aligned and driven down to complete the docking with the lower mold through the cooperation of the translation lifting assembly and the conveyor belt. Then, the docked upper mold and lower mold are transferred to the hot pressing molding machine through the third manipulator to complete the hot pressing molding. Finally, they are transferred back to the special-shaped mold clamping device on the conveyor belt through the third manipulator. Then, the upper mold and the lower mold are separated through the cooperation of the translation lifting assembly and the special-shaped mold clamping device located above, and the carbon fiber workpiece containing the metal core is taken out.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] Firstly, when the device is used, the upper mold and the lower mold of the carbon fiber part are first placed in a special-shaped mold clamping device respectively, and the upper mold and the lower mold are respectively fixed between the conveyor belt and the frame, and are located on the same vertical line. Subsequently, the carbon fiber prepreg feeding device on one side of the conveyor belt is controlled to work, and multiple layers of carbon fiber prepreg are attached to the upper and lower molds. After the carbon fiber prepreg is attached, an anti-permeation layer attaching device is controlled to work, and another anti-permeation layer is attached to the outside of the attached carbon fiber prepreg. Subsequently, the carbon fiber prepreg feeding device is controlled to work again, and the metal core located on the display table on one side of the conveyor belt is moved to below the output end of the carbon fiber prepreg feeding device. Multiple layers of carbon fiber prepreg are attached to the metal core by controlling the carbon fiber prepreg feeding device to work, and the anti-permeation layer attaching device is controlled again. Working, attaching an anti-permeation layer to the outside of the metal core wrapped with carbon fiber prepreg, putting the processed metal core into the lower mold by controlling the carbon fiber prepreg feeding device, and then moving the upper and lower molds to one side of the foaming material attaching device through the conveyor belt, controlling the foaming material attaching device to work, and attaching single-sided foaming material of corresponding thickness to the outside of the anti-permeation layer of the upper and lower molds according to the size of the workpiece, and finally controlling the two special-shaped mold clamping devices to close the upper and lower molds of the carbon fiber part, and performing hot pressing and curing molding through the hot pressing device on one side of the conveyor belt, and then controlling the two special-shaped mold clamping devices to separate the upper and lower molds, and take out the prepared carbon fiber workpiece containing the metal core, thereby achieving the effect of one-piece molding preparation for the carbon fiber workpiece without the need for a built-in foaming mold.

[0022] Secondly, before preparing the carbon fiber workpiece, the upper mold and the lower mold used for preparation need to be clamped and fixed by two special-shaped mold clamping devices respectively, and the mold is placed between the two clamping parts. The driving motor is controlled to drive the driving screw to rotate, thereby driving one of the clamping parts connected to the driving block to move toward the other clamping part, thereby achieving the effect of controlling the two clamping parts to clamp and fix it from both sides of the mold. After clamping and fixing, the translation lifting assembly and the conveyor belt are controlled to drive the fixed upper mold and the lower mold to move to the carbon fiber prepreg feeding device for prepreg attachment. Through the set translation lifting assembly, when it is necessary to control the movement of the upper mold, the translation plate can be driven to move linearly along the direction of the conveyor belt by controlling the first electric push rod to adjust the position of the upper mold to adapt to different processing procedures. The height of the upper mold can be adjusted by controlling the second electric push rod to achieve the docking of the upper mold and the lower mold. Through the set special-shaped vise, upper molds or lower molds of different shapes can be clamped and fixed.

[0023] Thirdly, after the upper mold and the lower mold are fixed by the special-shaped mold clamping device, it is necessary to attach multiple layers of carbon fiber prepreg to the inner walls of the upper mold and the lower mold, and the upper mold and the lower mold are transported to between the feeder and the first manipulator through the cooperation of the conveyor belt and the translation and lifting assembly. The first manipulator is controlled to take a certain amount of carbon fiber prepreg delivered by the feeder and attach it to the inner walls of the upper mold and the lower mold in turn.

[0024] Fourthly, after the work of attaching carbon fiber prepreg to the inner wall of the upper mold and the lower mold is completed, it is necessary to attach multiple layers of anti-permeability layers to the inside of the upper mold and the lower mold, and attach multiple layers of foaming material to the outside of the anti-permeability layer. Since the anti-permeability layer or the foaming material is rolled on the winder, it is necessary to cut it into a corresponding length before attaching the anti-permeability layer, and since there may be wrinkles on its surface, it is also necessary to flatten it to a flat state for subsequent attachment work. First, one end of the anti-permeability layer rolled up on the winder is pulled out by the second manipulator and laid flat on the operating table, and passed under the flattening drum and the cutting blade, and the flattening drum is driven down by the third electric push rod to make it contact with the upper surface of the anti-permeability layer. In the process of pulling the anti-permeability layer, the flattening drum continues to rotate on its surface to flatten it. After pulling to the required length, with the cooperation of the driving electric cylinder and the fourth electric push rod, the cutting blade is controlled to descend to contact the surface of the anti-permeability layer and move along one end to the other end, so as to realize the cutting work, and then the second manipulator is controlled to take the cut anti-permeability layer to the outside of the prepreg layer on the inner wall of the upper mold or the lower mold; after the prepreg layer and the anti-permeability layer of the upper mold and the lower mold are attached, the first manipulator is controlled to grab the metal core on the placement table and move it to the carbon fiber prepreg feeding device and the anti-permeability layer attaching device in turn to realize the attachment of the prepreg layer and the anti-permeability layer on its surface; then the metal core is placed inside the lower mold by the first manipulator, and then the single-sided pasted foam layer of corresponding thickness is attached to the outer side of the anti-permeability layer of the upper mold and the lower mold according to the size of the workpiece through the foaming material attaching device.

[0025] Fifth, after the prepreg layer, anti-permeation layer and foaming layer of the upper mold and the lower mold are attached, and the metal core is placed inside the lower mold, the upper mold and the lower mold are aligned through the cooperation of the translation lifting assembly and the conveyor belt, and the upper mold is driven down to complete the docking work with the lower mold. Then, the docked upper mold and lower mold are transferred to the hot pressing molding machine through the third manipulator to complete the hot pressing molding work, and finally transferred back to the special-shaped mold clamping device on the conveyor belt through the third manipulator, and then the upper mold and the lower mold are separated through the cooperation of the translation lifting assembly and the special-shaped mold clamping device located above, and the carbon fiber workpiece containing the metal core is taken out.
