Description

Technical Field

[0001] This application relates to the field of composite materials technology, and in particular to an automated production line for manufacturing flexible molding composite boxes. Background Technology

[0002] Composite material enclosures offer numerous significant advantages due to their unique material properties. They are high in strength and rigidity, yet lightweight, significantly reducing equipment load and improving energy efficiency. Their strong corrosion and weather resistance allows them to adapt to harsh environments and extend their service life. Excellent insulation properties result in outstanding electrical and thermal management performance. Flexible design allows for complex shapes and integrated structures, optimizing both appearance and function. High surface finish and aesthetically pleasing appearance are achieved, and some materials even possess electromagnetic shielding capabilities. These characteristics make composite material enclosures widely used in aerospace, automotive, electronics, and medical fields, making them an ideal choice for modern high-end manufacturing.

[0003] The autoclave process for composite material housings is a technology that cures and molds composite materials under high temperature and high pressure. It is currently one of the important methods for composite material molding. The process mainly involves: manually laying carbon fiber prepreg layer by layer onto a heated mold, then laying auxiliary materials (release cloth, perforated release film, breathable felt, vacuum bag film, and sealing strips, etc.), applying vacuum and pressure, and finally placing the product into an autoclave for heating. After the product cures, the autoclave is cooled and depressurized before it can be opened. The entire process—laying auxiliary materials, vacuuming, pressure holding, heating and curing, cooling, and then opening the door to remove the product—takes approximately 12 hours. However, this process has some drawbacks, such as high energy consumption and a long production cycle. These technical problems urgently need to be solved. Summary of the Invention The purpose of this invention is to overcome the shortcomings of the above-mentioned technologies and provide an automated production line for manufacturing flexible molding of composite material boxes, which reduces energy consumption and shortens the production cycle.

[0004] Therefore, the present invention provides an automated production line for manufacturing flexible molding of composite material boxes. The automated production line is equipped with a flexible molding device, which includes a heating mold device and a soft mold device, with the soft mold device positioned above the heating mold device.

[0005] The heating mold device includes a heating mold and a mold opening and closing device. The heating mold has mold side plates and a mold bottom plate, which together form an open-top inner concave mold area. The heating mold is a split mold. The mold side plates have movable side plates, which include a mold front plate, a mold rear plate, a mold left plate, and a mold right plate. Each movable side plate is equipped with a first heating plate, and the mold bottom plate is equipped with a second heating plate. The mold opening and closing device includes a first linear drive device and a power transmission device. The first linear drive device is connected to the power transmission device, and the power transmission device is connected to the movable side plates. Under the power output of the first linear drive device, the movable side plates are driven by the power transmission device to complete the mold opening or closing.

[0006] The soft mold device includes a lifting mechanism and a flexible airbag with air inlet and outlet. The lifting mechanism is equipped with a second linear drive device and a lifting platform. The telescopic rod of the second linear drive device is connected to the lifting platform, and the lifting platform is connected to the flexible airbag. Under the power output of the second linear drive device, the lifting platform drives the flexible airbag to enter or move out of the inner concave mold area of ​​the heated mold.

[0007] The beneficial effects of this invention are as follows: This invention provides an automated production line for manufacturing flexible molding of composite material boxes. The flexible molding device is equipped with a heating mold device and a soft mold device. Under the power output of the first linear drive device, the heating mold is opened or closed through the power transmission device, realizing time-saving and labor-saving demolding of the box. Under the power output of the second linear drive device, the flexible airbag is put into or taken out of the heating mold, so that the flexible airbag and the heating mold work together to form and solidify the box blank. It does not require the complex process of existing technology, has a short production cycle, and a short molding time. The molding time for each box is 0.5 hours, which is about 11.5 hours less than the complex process of autoclave, and has low energy consumption. Attached Figure Description

[0014] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0015] Depend on Figure 1 As shown, the present invention provides an automated production line for manufacturing composite material boxes using flexible molding. The automated production line is equipped with a flexible molding device 1, which is equipped with a heating mold device 2 and a soft mold device 3. The soft mold device 3 is positioned above the heating mold device 2.

[0016] Depend on Figure 2 , Figure 4 , Figure 5As shown, the heating mold device 2 includes a heating mold 13a and a mold opening and closing device 6a. The heating mold 13a is provided with a mold side plate and a mold bottom plate 1a. The mold side plate and the mold bottom plate 1a form an open-top inner concave mold area 2a. The heating mold 13a is a split mold. The mold side plate is provided with a movable side plate 3a. The movable side plate 3a is provided with a mold front plate 30a, a mold rear plate 31a, a mold left plate 32a, and a mold right plate 33a. Each movable side plate 3a is equipped with a first heating plate 4a. The mold bottom plate 1a is equipped with a second heating plate 5a. The mold opening and closing device 6a is provided with a first linear drive device 60a and a power transmission device. The first linear drive device 60a is connected to the power transmission device, and the power transmission device is connected to the movable side plate 3a. Under the power output of the first linear drive device 60a, the movable side plate 3a is driven by the power transmission device to complete the mold opening or closing. Depend on Figure 15 As shown, the soft mold device 3 includes a lifting mechanism 2b and a flexible airbag 3b with air inlet and outlet. The lifting mechanism 2b is equipped with a second linear drive device 20b and a lifting platform 21b. The telescopic rod of the second linear drive device 20b is connected to the lifting platform 21b, and the lifting platform 21b is connected to the flexible airbag 3b. The flexible airbag 3b is an existing airbag, which is prior art and will not be described in detail. Under the power output of the second linear drive device 20b, the lifting platform 21b drives the flexible airbag 3b to enter or move out of the inner concave mold area 2a of the heating mold 13a.

[0017] The working process of this invention is as follows: First, a pre-formed box shell is placed at the center of the heated mold 13a. This box shell is the box blank 4, which is a semi-finished product for manufacturing the box 5. It is an open-top box structure made of composite materials (such as carbon fiber prepreg). This is existing technology and will not be described in detail. Then, the first linear drive device 60a is started. Under the power output of the first linear drive device 60a, the movable side plate 3a is driven by the power transmission device to complete the mold closing, so that the outer surface of the box blank 4 corresponds to the inner wall surface of the inner concave mold area 2a.

[0018] Next, some gas is injected into the flexible airbag 3b, causing it to inflate. Then, under the power output of the second linear drive device 20b, the lifting platform 21b and the flexible airbag 3b fall together, causing the flexible airbag 3b to enter the receiving area of ​​the box blank 4 inside the heating mold 13a and stop. At this time, the bottom of the lifting platform 21b covers the upper opening of the heating mold 13a. Gas is then injected into the flexible airbag 3b, causing it to inflate and support the inner surface of the box blank 4, so that the outer surface of the box blank 4 is tightly attached to the inner wall of the heating mold 13a (by...). Figure 8 As shown in the figure, the heating mold 13a heats the box blank 4, and the box blank 4 is cured by heat, thus completing the molding of the composite material box 5.

[0019] Finally, gas is drawn out from the flexible airbag 3b, and the flexible airbag 3b becomes smaller and detaches from the inner surface of the composite material box 5; under the power output of the second linear drive device 20b, the lifting platform 21b and the flexible airbag 3b rise together and return to their original positions, so that the flexible airbag 3b is removed from the composite material box 5; after the composite material box 5 cools down, it is taken out from the heating mold 13a, completing the preparation of the composite material box 5.

[0020] This invention provides an automated production line for manufacturing flexible molding of composite material boxes. The flexible molding device 1 is equipped with a heating mold device 2 and a soft mold device 3. Under the power output of the first linear drive device 60a, the heating mold 13a is opened or closed through the power transmission device, realizing the demolding of the box body 5 in a time-saving and labor-saving manner. Under the power output of the second linear drive device 20b, the flexible airbag 3b is put into or taken out of the heating mold 13a, so that the flexible airbag 3b and the heating mold 13a work together to form and solidify the box body blank 4. It does not require the complex process of existing technology, has a short production cycle, and a short molding time. The molding time for each box is 0.5 hours, which is about 11.5 hours less than the complex process of autoclave, and has low energy consumption.

[0021] In some embodiments, preferably, by Figure 2 , Figures 6-8 , Figure 19 As shown, the heating mold 13a is also provided with a mold top plate 34a, and an electric heating tube 7a is installed on the mold top plate 34a. The mold top plate 34a has a hollow frame structure. The mold top plate 34a is installed at the bottom of the lifting platform 21b. The flexible airbag 3b passes upward through the hollow channel 342a of the mold top plate 34a and is detachably and fixedly connected to the lifting platform 21b. The inner side of the bottom periphery of the hollow frame of the mold top plate 34a is set as an inverted flange shape 341a. The outer side of the bottom periphery of the hollow frame of the mold top plate 34a is detachably connected to each movable side plate 3a.

[0022] When the open edge 5c of the composite material box 5 is designed as an undercut flange structure, the inner side of the bottom periphery of the hollow frame of the mold top plate 34a is set with a matching undercut flange shape 341a at the corresponding position. When producing the composite material box 5, under the power output of the second linear drive device 20b, the mold top plate 34a and the flexible airbag 3b fall together under the drive of the lifting platform 21b, so that the flexible airbag 3b enters the receiving area of ​​the box blank 4 located in the heating mold 13a directly below it and stops. At this time, the mold top plate 34a acts as a heating plate located on top of the heating mold 13a, with the outer periphery of the bottom of the hollow frame pressing against the top of the mold side plate of the heating mold 13a, and the inner periphery of the bottom of the hollow frame pressing against the upper open edge 5c of the box blank 4; gas continues to be filled into the flexible airbag 3b, so that the flexible airbag 3b expands and supports the inner surface of the box blank 4, so that the outer surface of the box blank 4 is tightly attached to the heating mold 13a. In step a, the open edge 5c of the box blank 4 is tightly attached to the inner side of the bottom periphery of the hollow frame of the mold top plate 34a, so that the open edge 5c of the box blank 4 forms an undercut flange structure that matches the undercut flange shape 341a; at the same time, the heating mold 13a (including the mold top plate 34a, mold side plate, and mold bottom plate 1a) heats the box blank 4, and the box blank 4 is cured by heat, completing the molding of the composite material box 5; finally, gas is sucked out from the flexible airbag 3b, and under the power output of the second linear drive device 20b, the lifting platform 21b, the mold top plate 34a, and the flexible airbag 3b rise together and return to their original positions. After the composite material box 5 cools down, it is taken out, completing the preparation of the composite material box 5. The other steps are the same as the preparation steps of the composite material box 5 described above, and will not be repeated.

[0023] In some embodiments, preferably, by Figure 7 , Figure 8As shown, the mold top plate 34a and the movable side plate 3a are detachably connected by a first mortise and tenon structure 9a, which makes the positioning of the mold top plate 34a and the movable side plate 3a more accurate when the mold is closed, and the connection between the two is more secure after the mold is closed. The first mortise and tenon structure 9a can be existing technology, such as plug-in connection, etc. The structure can also be: a first tenon 92a is provided on the upper surface of the movable side plate 3a, that is, on the mold front plate 30a, mold rear plate 31a, mold left plate 32a, and mold right plate 33a respectively, and a corresponding first mortise hole 91a is provided on the bottom of the mold top plate 34a. The first mortise hole 91a and the first tenon 92a match to form the first mortise and tenon structure 9a. After the movable side plate 3a is closed, the mold top plate 34a is placed on the movable side plate 3a. At this time, the first tenon 92a on the movable side plate 3a is inserted into the first mortise 91a at the bottom of the mold top plate 34a, completing the positioning and fixing between the mold top plate 34a and the movable side plate 3a. After the box blank 4 in the heating mold device 2 is formed into the box 5, the mold top plate 34a is lifted off the movable side plate 3a. The first mortise 91a at the bottom of the mold top plate 34a is disengaged from the first tenon 92a on the movable side plate 3a at its bottom, completing the separation between the mold top plate 34a and the movable side plate 3a. Then the movable side plate 3a is opened, and finally the box 5 is taken out.

[0024] In some embodiments, preferably, by Figure 5 , Figure 8 As shown, two adjacent movable side plates 3a in the mold front plate 30a, mold rear plate 31a, mold left plate 32a, and mold right plate 33a are detachably connected by a second tenon structure 16a, which makes the positioning of the two adjacent movable side plates 3a more accurate when the mold is closed, and the connection between them is more secure after the mold is closed. The second tenon structure 16a can be existing technology, such as plug-in connection, etc. The structure can also be: at the junction of two adjacent movable side plates 3a, one movable side plate 3a is provided with a second tenon 162a, and the other movable side plate 3a is provided with a corresponding second mortise hole 161a. The second mortise hole 161a and the second tenon 162a match to form the second tenon structure 16a. When the movable side plate 3a is closed, the second tenon 162a is inserted into the second mortise 161a at the junction between two adjacent movable side plates 3a, thus completing the positioning and fixing between the two adjacent movable side plates 3a; when the movable side plate 3a is opened, the second tenon 162a between the two adjacent movable side plates 3a is disengaged from the second mortise 161a, thus completing the separation between the two adjacent movable side plates 3a.

[0025] In some embodiments, preferably, by Figure 4 , Figure 9 , Figure 10As shown, the heating mold device 2 is also provided with a wedge locking mechanism 8a. The number of wedge locking mechanisms 8a is set to multiple groups. Each group of wedge locking mechanisms 8a includes a locking block 81a with a locking hole 811a, a wedge locking device 82a, and a third linear drive device 83a. The locking block 81a and the wedge locking device 82a are respectively installed at the edge between two adjacent movable side plates 3a, at the edge between the movable side plate 3a and the mold bottom plate 1a, and at the edge between the movable side plate 3a and the mold top plate 34a.

[0026] Depend on Figure 9 As shown, the wedge locking device 82a includes a first fixing plate 821a and a wedge locking plate 822a. The wedge locking plate 822a is mounted on the first fixing plate 821a and is slidably connected to the first fixing plate 821a. The wedge locking plate 822a has a ramp 8221a structure. The upper surface of the wedge locking plate 822a has a ramp 8221a. The front end of the wedge locking plate 822a has a boss 8222a, which is directly opposite the lock hole 811a of the locking block 81a. The boss 8222a can be inserted into the lock hole 811a or pulled out of the lock hole 811a. The bottom of the wedge locking plate 822a has a protrusion 8223a. The first fixing plate 821a... A guide groove 8211a is provided on 1a, and a protrusion 8223a is set in the guide groove 8211a; a spring 823a is installed in the guide groove 8211a, and the spring 823a presses the protrusion 8223a into the guide groove 8211a by its elastic force. The telescopic rod of the third linear drive device 83a faces the inclined surface 8221a of the wedge lock plate 822a; the third linear drive device 83a provides power to the inclined surface 8221a. Through the extension and retraction of the telescopic rod of the third linear drive device 83a, the wedge lock plate 822a moves left and right on the first fixed plate 821a, so that the protrusion 8222a can be inserted into the lock hole 811a or pulled out of the lock hole 811a.

[0027] In use, according to actual needs, the wedge locking mechanism 8a is respectively installed at the edge between two adjacent movable side plates 3a, at the edge between the movable side plate 3a and the mold base plate 1a, and at the edge between the movable side plate 3a and the mold top plate 34a. For example, the locking block 81a is installed at the edge of the movable side plate 3a, and the wedge locking device 82a is installed at the edge of another adjacent movable side plate 3a. The telescopic rod of the third linear drive device 83a faces the inclined surface 8221a of the wedge locking plate 822a. The third linear drive device 83a can be adjusted according to the actual needs. Install the device on the existing frame according to the actual situation. The power provided by the telescopic rod of the third linear drive device 83a is applied to the inclined surface 8221a. The telescopic rod of the third linear drive device 83a pushes the wedge locking plate 822a, and the spring 823a applies an elastic force to the wedge locking plate 822a, so that the wedge locking plate 822a can move back and forth on the first fixed plate 821a, allowing the boss 8222a to be inserted into or pulled out of the lock hole 811a. The locking or unlocking of the wedge locking mechanism 8a is used to lock or unlock the two adjacent movable side plates 3a. The other two installation and use methods are similar and will not be described in detail.

[0028] When the operator installs the wedge locking mechanism 8a at the edge between the movable side plate 3a and the mold top plate 34a according to actual needs, it is... Figure 4 , Figure 9 , Figure 19 As shown, since the mold top plate 34a and a portion of the third linear drive devices 83a are installed on the lifting platform 21b, they rise or fall together with the lifting platform 21b. Therefore, it is important to activate the telescopic rod of the third linear drive device 83a to push the wedge locking plate 822a to move left and right, so as to prevent the boss 8222a from obstructing the descent of the mold top plate 34a and its engagement with the mold side plate, and from the descent of the mold top plate 34a and its separation from the mold side plate. The specific operation is as follows: when the mold top plate 34a descends to above the mold side plate, the telescopic rod of the third linear drive device 83a needs to be activated to push the wedge locking plate 822a to the right, so that the boss 8222a moves to the right with the wedge locking plate 822a, giving the mold top plate 34a room to continue descending; after the mold top plate 34a engages with the mold side plate, the telescopic rod of the third linear drive device 83a is activated to retract and disengage from the wedge locking plate 822a, completing the locking of the mold top plate 34a and the mold side plate. After the housing 5 is prepared, the telescopic rod of the third linear drive device 83a is activated to push the wedge locking plate 822a to the right, thereby unlocking the mold top plate 34a from the mold side plate. During the process of the mold top plate 34a rising and separating from the mold side plate, the telescopic rod of the third linear drive device 83a needs to be activated to extend and press against the wedge locking plate 822a, so that the boss 8222a remains in the unlocked state until the bottom surface of the mold top plate 34a is above the boss 8222a.

[0029] In some embodiments, preferably, by Figure 2 , Figures 11-13 As shown, the power transmission device includes a linear guide device 61a, a pair of transmission devices 62a, and a gear rotating device 63a. The linear guide device 61a includes two parallel linear guide rails 611a. The pair of transmission devices 62a are installed at opposite intervals at both ends of the linear guide rails 611a. Each transmission device 62a includes a slide 621a, a first bracket 622a, and a fixed frame 623a. The slide 621a is slidably connected to the linear guide rails 611a. The fixed frame 623a is connected to the slide 621a through the first bracket 622a and to one of the movable side plates 3a through a connecting plate 14a. The power output end of the first linear drive device 60a is connected to one of the transmission devices 62a. The gear rotating device 63a includes a rack 631a and a gear 632a. The rack 631a is parallel to the linear guide rail 611a, and the rack 631a has a first rack 6311a and a second rack 6312a arranged in an alternating parallel configuration. The gear 632a is fixed on the rotating shaft 633a and is located between the first rack 6311a and the second rack 6312a, meshing with both racks simultaneously. The gear rotating device 63a is positioned between a pair of transmission devices 62a. The end of the first rack 6311a away from the gear 632a is connected to one transmission device 62a, and the end of the second rack 6312a away from the gear 632a is connected to the other transmission device 62a. There are two sets of mold opening and closing devices 6a, which are spaced vertically and arranged in a cross shape when viewed from above. The heating mold 13a is installed between a pair of transmission devices 62a of the upper mold opening and closing device 6a. A third linear drive device 83a is partially installed on the fixed frame 623a.

[0030] In use, each movable side plate 3a of the heating mold 13a, namely the front plate 30a, rear plate 31a, left plate 32a, and right plate 33a, is connected to the transmission device 62a of the corresponding mold opening and closing device 6a via a connecting plate 14a. Specifically, one pair of transmission devices 62a of one set of mold opening and closing devices 6a is connected to the front plate 30a and rear plate 31a of the mold via connecting plates 14a, and another pair of transmission devices 62a of another set of mold opening and closing devices 6a is connected to the left plate 32a and right plate 33a of the mold via connecting plates 14a. Figure 2 , Figure 3As shown. In each set of mold opening and closing devices 6a, the first linear drive device 60a drives a transmission device 62a to slide along the linear guide rail 611a. Through the gear and rack transmission of the gear rotating device 63a, another transmission device 62a is driven to slide along the linear guide rail 611a. Due to the above-mentioned structure of the gear rotating device 63a, the two transmission devices 62a slide in opposite directions on the linear guide rail 611a, so that the mold front plate 30a and mold rear plate 31a, mold left plate 32a and mold right plate 33a, which are in relative positions, open or close the mold at the same time.

[0031] In some embodiments, preferably, by Figure 5 As shown, corresponding guide grooves 10a are provided on the mold base plate 1a along the opening or closing direction of each movable side plate 3a, and guide blocks 35a are provided at the bottom of each movable side plate 3a. The guide blocks 35a are slidably connected to their matching guide grooves 10a. This makes the opening or closing movement of the mold front plate 30a, mold rear plate 31a, mold left plate 32a, and mold right plate 33a along their respective guide grooves 8211a on the mold base plate 1a more stable.

[0032] In some embodiments, preferably, by Figure 3 As shown, the heating mold device 2 is also provided with a support base 11a. The support base 11a is provided with a support table 111a and support table legs 112a connected to the support table 111a. The heating mold 13a is installed on the support table 111a, so that the heating mold 13a is more stable and reliable during use.

[0033] In some embodiments, preferably, by Figure 2 As shown, the heating mold device 2 is also provided with a bottom support 12a, on which a support base 11a and a mold opening and closing device 6a are installed. The structure is simple and easy to install.

[0034] In some embodiments, preferably, by Figure 15 , Figure 19As shown, the soft mold device 3 includes a first frame 1b, which has a platform frame 10b and a standing frame 11b. The standing frame 11b is connected to the platform frame 10b. A second linear drive device 20b is installed on the platform frame 10b. A longitudinal guide rail 110b is installed on the standing frame 11b. A lifting platform 21b has a fixed platform 211b and a second fixed plate 212b. The second fixed plate 212b is installed at the bottom of the fixed platform 211b. A roller 210b is installed on the fixed platform 211b and is tactilely connected to the longitudinal guide rail 110b. A mold top plate 34a is installed at the bottom of the second fixed plate 212b. A flexible airbag 3b passes upward through the hollow channel 342a of the mold top plate 34a and is detachably fixed to the second fixed plate 212b. The lifting platform 21b rises or falls along the longitudinal guide rail 110b via rollers 210b, making the lifting platform 21b and the flexible airbag 3b more stable and reliable during their joint rise or fall. Operators can replace the flexible airbag 3b according to actual production conditions.

[0035] In some embodiments, preferably, the soft tire mold device 3 is further provided with a support mechanism 6b, the support mechanism 6b is provided with a fourth linear drive device 60b and a support member 61b, the middle part of the support member 61b is hinged to the standing frame 11b through a rotating shaft 62b, one end of the support member 61b is hinged to the telescopic rod of the fourth linear drive device 60b, and the cylinder of the fourth linear drive device 60b is hinged to the platform frame 10b; under the action of the fourth linear drive device 60b, the support member 61b can swing around the rotating shaft 62b to support or release the flexible airbag 3b.

[0036] Depend on Figure 14 , Figure 16 As shown, when producing the composite material box 5, the operator activates the fourth linear drive device 60b to retract its telescopic rod, causing the support member 61b to swing around the rotation axis 62b to release the flexible airbag 3b, thus releasing the support state of the flexible airbag 3b. Some gas is then injected into the flexible airbag 3b, causing it to expand, preparing it for descending together with the lifting platform 21b to participate in the molding of the composite material box 5. When the invention is not used for an extended period, the flexible airbag 3b hangs suspended in mid-air for a long time, making it susceptible to collision damage and cracking under its own weight, shortening its service life. Therefore, the operator extracts the gas from the flexible airbag 3b, reducing its volume and weight, and activates the fourth linear drive device 60b to extend its telescopic rod, causing the support member 61b to swing around the rotation axis 62b to support the flexible airbag 3b.

[0037] In some embodiments, preferably, by Figure 14 , Figures 16-18The number of supporting mechanisms 6b shown is one pair, and the two are installed facing each other from left to right. Each supporting mechanism 6b has a supporting member 61b with multiple supporting rods 610b arranged side by side at intervals. One end of each supporting rod 610b is connected to an upwardly curved flange 612b, and the other end of each supporting rod 610b is connected to a connecting rod 611b. The connecting rod 611b is hinged to the telescopic rod of the fourth linear drive device 60b. The middle part of each supporting rod 610b is connected to a rotating shaft 62b. Hinged onto the standing frame 11b; under the respective action of the fourth linear drive device 60b of the pair of support mechanisms 6b, the support members 61b located on the left and right sides can simultaneously swing around their respective rotation axes 62b to support or release the flexible airbag 3b; when the support members 61b located on the left and right sides simultaneously swing around their respective rotation axes 62b to support the flexible airbag 3b, their support rods 610b are arranged in a staggered manner, and the flexible airbag 3b is positioned between the side flanges 612b on both sides. The pair of support mechanisms 6b work together to make the support state of the flexible airbag 3b more stable and reliable.

[0038] In some embodiments, preferably, by Figure 19 As shown, the soft tire mold device 3 is also equipped with an air inlet / outlet mechanism 4b. The air inlet / outlet mechanism 4b is equipped with an air inlet / outlet connector 40b and an air inlet / outlet pipe 41b. The air inlet / outlet connector 40b is installed on the fixed platform 211b. The upper end of the air inlet / outlet pipe 41b is sealed and connected to the air inlet / outlet connector 40b, and the lower end of the air inlet / outlet pipe 41b passes downward through the second fixed plate 212b and is sealed and connected to the air inlet / outlet of the flexible airbag 3b. In use, the air inlet / outlet connector 40b can be connected to an existing inflation / inhalation device (such as a two-way inflation pump) through an external pipeline to realize the inflation or desorption of gas into the flexible airbag 3b.

[0039] In some embodiments, preferably, such as Figure 19 As shown, the soft tire mold device 3 is also provided with a guide mechanism 9b. The guide mechanism 9b is provided with a guide rod 91b and a guide sleeve 92b. One end of the guide rod 91b is connected to the fixed platform 211b, and the other end of the guide rod 91b passes upward through the guide sleeve 92b and extends out. The guide sleeve 92b is connected to the platform frame 10b. The guide rod 91b and the guide sleeve 92b are slidably connected. The guide rod 91b is arranged parallel to the telescopic rod of the first linear drive device 60a, so that the lifting platform 21b and the flexible airbag 3b are more stable and reliable during the process of rising or falling together.

[0040] In some embodiments, preferably, by Figure 1 , Figures 20-23As shown, the automated production line also includes a robotic arm 3c, which has a robotic arm 30c and a gripping device 2c. The gripping device 2c is detachably mounted on the end of the robotic arm 30c via a connecting seat 22c. The gripping device 2c can be easily and quickly replaced according to the actual dimensions of the box blank 4 or box 5. In this embodiment, the robotic arm 30c is a multi-joint robotic arm 30c. A multi-joint robotic arm 30c is a highly flexible and precise automated device capable of efficiently completing complex tasks and improving production efficiency and quality. A multi-joint robotic arm 30c typically includes servo motors, multiple joints, and other components; it is an existing device and will not be described in detail here.

[0041] Depend on Figures 21-23 As shown, the gripping device 2c preferably has a second frame 20c, which has multiple support rods 21c. The multiple support rods 21c are connected to each other to form an approximately square-shaped mesh structure. The mesh-shaped approximately square-shaped second frame 20c is more stable. A gripping mechanism 1c is installed in the middle of each of the four sides of the square shape, so that the force on the four side walls of the entire box blank 4 or box 5 is more balanced and stable during the gripping and transportation of the box blank 4 or box 5.

[0042] Depend on Figure 24 As shown, the clamping mechanism 1c preferably includes a second bracket 10c and a clamp. The clamp includes a left clamp 11c and a right clamp 12c. The clamping mechanism 1c also includes a fifth linear drive device 13c and a sixth linear drive device 14c. The fifth linear drive device 13c and the sixth linear drive device 14c are respectively installed vertically and intermittently on the second bracket 10c, with the fifth linear drive device 13c positioned above the sixth linear drive device 14c. The telescopic rod of the fifth linear drive device 13c is connected to the left clamp 11c, and the telescopic rod of the sixth linear drive device 14c is connected to the right clamp 12c. The right clamp 12c is directly opposite the lower part of the left clamp 11c. The left clamp 11c is connected to a left buffer pad 16c, and the right clamp 12c is connected to a right buffer pad 17c. The left buffer pad 16c and the right buffer pad 17c are arranged opposite each other, and there is a reserved space 15c between them to allow the open edge 5c of the box 5 to pass through.

[0043] When using, by Figure 1 As shown, a robotic arm 3c grips the box blank 4 and places it into the heating mold 13a. The box blank 4 solidifies and forms the box 5. After the mold is opened, the robotic arm 3c grips the box 5 from the heating mold 13a, which is convenient, fast, and improves production efficiency. Regarding the gripping mechanism 1c, taking the gripping of the box 5 as an example, it is... Figure 25As shown, under the action of the fifth linear drive device 13c and the sixth linear drive device 14c, the distance between the left clamp 11c and the right clamp 12c gradually increases. When the left buffer pad 16c and the right buffer pad 17c reach the reserved space 15c that allows the open edge 5c of the box 5 to pass through, the clamping mechanism 1c descends as a whole. After the open edge 5c of the box 5 passes through the reserved space 15c upwards, the left clamp 11c is located on the outside of the box 5, and the right clamp 12c is located on the inside of the box 5. Under the drive of the fifth linear drive device 13c and the sixth linear drive device 14c, the distance between the left clamp 11c and the right clamp 12c gradually decreases until they cooperate to clamp the box wall below the open edge 5c of the box 5, thus realizing the gripping of the box 5 with the open edge 5c designed as an inverted flip-up edge. When gripping and moving the box 5, the left buffer pad 16c and the right buffer pad 17c play a buffering role to prevent the left clamp 11c and the right clamp 12c from scratching the box wall below the open edge 5c of the box 5. They can be made of existing materials with elasticity such as rubber.

[0044] In some embodiments, preferably, by Figure 26 As shown, the automated production line also includes a box transfer and positioning fixture. This fixture has a base 3d, and a railing 4d is connected to the base 3d. The railing 4d is used to place box blanks 4 or boxes 5. An adjustable device is installed inside the railing 4d, which includes a limit baffle 5d and a screw 6d. The limit baffle 5d is positioned inside the railing 4d, and one end of the screw 6d is connected to the limit baffle 5d. The other end of the screw 6d passes through the railing 4d and extends out to be threadedly connected to a nut 7d. The other end of the screw 6d has a thread for adjusting its length. By twisting the nut 7d, the position of the nut 7d on the thread is set, adjusting the length of the screw 6d within the railing 4d, thereby adjusting the distance between the limit baffle 5d and the inside of the railing 4d to accommodate box blanks or boxes 5 of different sizes.

[0045] The box transfer and positioning fixture includes a first box transfer and positioning fixture 1d and a second box transfer and positioning fixture 2d. The first box transfer and positioning fixture 1d is used to place the box blank 4, and the second box transfer and positioning fixture 2d is used to place the box 5.

[0046] This invention provides an automated production line for flexible molding of composite material boxes, which eliminates the need for auxiliary raw materials, saving a significant amount of raw materials. The molding time is short, with each box taking only 0.5 hours to mold, a reduction of approximately 11.5 hours compared to the complex autoclave process. The short molding time also results in low energy consumption, making it energy-efficient and environmentally friendly. It solves the problems of complex manual operation, difficult product transfer, long curing time, and slow temperature rise during the autoclave production of carbon fiber boxes, saving auxiliary raw materials, reducing energy consumption, and improving product production cycle time.

[0047] It should be noted that: (1) The first linear drive device 60a, the second linear drive device 20b, the third linear drive device 83a, the fourth linear drive device 60b, the fifth linear drive device 13c, and the sixth linear drive device 14c can be existing linear drive devices such as hydraulic cylinders, pneumatic cylinders, and electric cylinders.

[0048] (2) One of the usage processes of this invention is as follows: ① Place the box blank 4 inside the enclosure 4d of the first box transfer and positioning fixture 1d, and heat the heating mold 13a at the same time; ②When the heating mold 13a is heated to the set temperature, the robot arm 3c is started to clamp the box blank 4 on the first box transfer and positioning fixture 1d to the side of the heating mold device 2. ③ Unlock the wedge locking mechanism 8a of the heating mold 13a in the heating mold device 2. After the mold opening is completed, the robot arm 3c puts the box blank 4 into the heating mold 13a. The heating mold device 2 completes the mold closing, as well as the mold locking between the two adjacent movable side plates 3a and the mold bottom plate 1a. ④ The flexible airbag 3b of the soft mold device 3 is lowered until it is placed inside the box blank 4 of the heated mold 13a. The heated mold device 2 completes the mold closing and the locking between the movable side plate 3a and the mold top plate 34a. The flexible airbag 3b is pressurized and inflated to maintain pressure, so that the inner cavity of the mold fits tightly with the product. Since the heated mold 13a is in a heated state, the box 5 will be shaped according to the shape of the inner cavity of the mold. ⑤ The heating plate of the heating mold device 2 heats and solidifies the box blank 4; ⑥ After curing is complete, the heating mold device 2 unlocks and opens the mold; ⑦ The robotic arm 3c takes out the solidified box 5 and places it inside the fence 4d of the second box transfer and positioning fixture 2d, and then transfers it to the designated position of the product.
