Description

TECHNICAL FIELD

[0003] The existing forming process is: first, cut the continuous glass fiber rod into short glass fiber rods of a predetermined length; then, polish the outer surface of each short glass fiber rod separately to improve its bonding force with the glue; then, manually apply glue to each short glass fiber rod after polishing and perform drying treatment; finally, arrange the plurality of short glass fiber rods after gluing in order manually, keep them in a dense and parallel state, and put them into a mold together with rubber raw materials for molding, and finally obtain a composite component.

[0022] Please refer to Figures 1 to 10 As shown in the drawings, the present application provides a forming device for composite material assembly of non-pneumatic tire support leg, which comprises unwinding device, polishing device 1, first guide roller group 21, second guide roller group 22, first dipping tank 3, first drying device 4, second dipping tank 5, second drying device 6, traction device 8 and cutting and molding device 9 arranged in turn along the conveying direction of glass fiber rod. The unwinding device is used for synchronous unwinding of multiple rolls of glass fiber rod material. In the embodiment, the unwinding device adopts a multi-head pay-off rack, which has the function of simultaneous pay-off of multiple shafts and multiple discs, can realize constant tension and non-twisting pay-off, and can meet the synchronous unwinding requirements of multiple rolls of glass fiber rod material in the embodiment.

It should be noted that the specific installation process and working principle of the multi-head pay-off rack belong to the prior art, which will not be described here, and the unwinding device is not shown in the drawings.

[0023] Please refer to Figure 3 The polishing device 1 comprises a box body 11 and a plurality of polishing mechanisms and a dust collection mechanism 12 arranged in the box body 11. The two sides of the box body 11 are respectively provided with an input port 111 and an output port 112. One polishing mechanism is arranged corresponding to one glass fiber rod. Each polishing mechanism comprises a first polishing assembly 13 and a second polishing assembly 14, which cooperate to continuously polish the outer surface of the glass fiber rod. The dust collection mechanism 12 is arranged close to the output port 112 and is used for adsorbing the dust generated during polishing. The roughness of the outer surface of the glass fiber rod is improved through polishing, thereby enhancing the adhesion performance of the glass fiber rod with the adhesive in the subsequent process. The dust collection mechanism 12 is used to realize real-time adsorption of the dust generated during polishing, so as to avoid the dust adhering to the surface of the glass fiber rod or floating into the production environment, thereby preventing the dust from affecting the combination effect of the adhesive and the glass fiber rod in the subsequent dipping process.

[0024] Please refer to Figure 8The output end of the traction device 8 is provided with two synchronous reverse rotating traction rollers 81, which cooperate to pull all the glass fiber rods along the X direction, realizing the fixed-length conveying of the plurality of glass fiber rods.

[0025] Please refer to Figure 9 The cutting and molding device 9 comprises a frame 91, a first lifting assembly 92 arranged on the top of the frame 91, an upper die 93 arranged at the output end of the first lifting assembly 92, a lower die 94 slidably connected to the bottom of the frame 91 along the Y direction, and a cutting mechanism 95 arranged on the frame 91; the lower die 94 is provided with a pressing cavity 942 matched with the upper die 93; the cutting mechanism 95 is located on the side of the lower die 94 close to the traction mechanism, and is used for cutting all the glass fiber rods a2. During cutting and molding, the first rubber sheet a11 is first placed in the pressing cavity 942, and the lower die 94 is pushed into the lower part of the upper die 93 along the Y direction; the traction device 8 sends the plurality of glass fiber rods a2 to the upper part of the first rubber sheet a11; then the second rubber sheet a12 is placed on the glass fiber rods a2, the first lifting assembly 92 drives the upper die 93 to move downward to combine with the lower die 94, and the three are pressed into one body; after the molding is completed, the cutting mechanism 95 acts to cut all the glass fiber rods a2 at one time along the preset position of the input end of the pressing cavity 942, and finally obtains the fixed-length composite component assembly a for non-pneumatic tire support legs; after the cutting is completed, the lower die 94 can be slid out along the Y direction again, so as to facilitate taking out the formed composite component assembly a.

[0026] The non-pneumatic tire support leg composite component forming equipment of the embodiment realizes continuous production through the cooperation of various devices, and the production process is as follows: the unwinding device first unwinds the multiple rolls of glass fiber rod materials synchronously, and the released glass fiber rods enter the polishing device 1; the polishing mechanism corresponding to each single glass fiber rod in the box 11 continuously polishes the surface of the rod body to improve the roughness, and the dust suction mechanism 12 adsorbs the dust generated by polishing in real time to avoid affecting the adhesion effect of the subsequent adhesive. After being polished, the multiple glass fiber rods are regularly guided through the first guide roller group 21 and the second guide roller group 22, sequentially enter the first dipping tank 3 to complete the bottom coating dipping, and then are dried and solidified through the first drying device 4; then, the glass fiber rods enter the second dipping tank 5 to complete the surface coating dipping, and are dried again through the second drying device 6, so as to ensure that the adhesive is uniformly attached to the surface of the rod body and is stably solidified. Then, the traction device 8 stably clamps and pulls all the glass fiber rods along the X direction to realize fixed-length conveying. After the glass fiber rods reach the cutting and molding device 9, the upper mold 93 and the lower mold 94 are cooperated to press the first rubber sheet, the glass fiber rod and the second rubber sheet into one body, and then the cutting mechanism 95 cuts all the glass fiber rods at one time, so that a single composite component is formed. The device realizes the full-process continuous operation of the glass fiber rod from unwinding, polishing, dipping, drying, fixed-length pulling to molding and synchronous cutting, reduces the manual participation, effectively improves the production efficiency, ensures the uniformity and firmness of the adhesive attached to the surface of the glass fiber rod through continuous polishing and twice dipping and drying, ensures the size consistency and structural stability of the composite component through the cooperation of fixed-length pulling, molding and synchronous cutting, improves the product yield, and solves the problems of low efficiency and large quality fluctuation caused by manual operation in the traditional process.

[0027] In the embodiment, each polishing mechanism includes two first polishing assemblies 13 and one second polishing assembly 14, the two first polishing assemblies 13 and the second polishing assembly 14 are arranged in the X direction at intervals, and the second polishing assembly 14 is located between the two first polishing assemblies 13; wherein the first polishing assembly 13 is used for polishing the upper and lower surfaces of the glass fiber rod; and the second polishing assembly 14 is used for polishing the left and right surfaces of the glass fiber rod.

[0028] Preferably, the polishing mechanisms corresponding to the adjacent two glass fiber rods are arranged in front and back staggered manner along the conveying direction of the glass fiber rod. Through the above arrangement, the transverse arrangement width of the multiple glass fiber rods can be reduced without affecting the independent polishing effect of the single glass fiber rod, which is beneficial to the smooth passing of the subsequent multiple glass fiber rods through the first guide roller group 21 and the second guide roller group 22, and ensures the stability of the guidance driving; in addition, the overall width size of the polishing device 1 can also be directly shortened, and the floor area of the equipment can be reduced.

[0029] In a preferred embodiment, referring to Figure 4, the first polishing assembly 13 comprises a first support 131 and two first grinding wheels 132, specifically, the two first grinding wheels 132 are arranged along the Z direction; the peripheral wall of each first grinding wheel 132 is provided with a first annular groove 133 matched with the glass fiber rod; the two sides of each first grinding wheel 132 are rotatably connected with a first sliding block 134, the first sliding block 134 is slidably connected with the first support 131 along the Z direction, and a first elastic assembly 135 is arranged between the first sliding block 134 and the first support 131, and the two first elastic assemblies 135 cooperate to keep the upper and lower surfaces of the two first grinding wheels 132 in stable contact with the glass fiber rod. During polishing, the glass fiber rod is arranged between the two first grinding wheels 132, and through the self-adaptive adjustment function of the two first elastic assemblies 135, the slight diameter deviation of the glass fiber rod can be automatically compensated, and the slight vibration in the conveying process can be offset, so that the first grinding wheel 132 and the surface of the rod body always maintain uniform and stable polishing pressure, avoiding insufficient polishing or local over-polishing.

By screwing in or out the first adjusting screw 1352, the cross bar 1351 can be driven to move along the Z direction, and the elastic force of the first spring 1354 can be adjusted by changing the compression amount, so as to flexibly adjust the pressure of the first grinding wheel 132 on the glass fiber rod. The pressure can be fine-tuned according to the polishing effect, to ensure sufficient polishing while avoiding damage to the rod body, and to improve the polishing quality stability.

[0031] In a preferred embodiment, referring to Figure 5 , the second polishing assembly 14 comprises a second support 141 and two second grinding wheels 142, specifically, the two second grinding wheels 142 are arranged along the Y direction; the peripheral wall of each second grinding wheel 142 is provided with a second annular groove 143 matched with the glass fiber rod; the two sides of each second grinding wheel 142 are rotatably connected with a second sliding block 144, the second sliding block 144 is slidably connected with the second support 141 along the Y direction, and a second elastic assembly 145 is arranged between the second sliding block 144 and the second support 141, and the two second elastic assemblies 145 cooperate to keep the left and right surfaces of the two second grinding wheels 142 in stable contact with the glass fiber rod. During polishing, the glass fiber rod is arranged between the two second grinding wheels 142, and similarly, through the self-adaptive adjustment function of the second elastic assembly 145, the left and right surfaces of the second grinding wheel 142 and the rod body always maintain uniform and stable polishing pressure.

[0032] Specifically, referring to Figure 5 , the second elastic assembly 145 comprises a second adjusting screw 1451 screwed with the side wall of the second support 141, and a second spring 1452 is arranged between each second sliding block 144 and the second adjusting screw 1451.

Similarly, the pressure can be fine-tuned in real time according to the actual grinding effect, further improving the stability of the grinding quality.

[0033] Preferably, referring to Figure 3 , the first support 131 and the second support 141 are detachably mounted in the box body 11 by screws, facilitating the overall disassembly of the first grinding assembly 13 and the second grinding assembly 14 for replacement or maintenance of the worn grinding wheel. In addition, the first adjusting screw 1352 of the first elastic assembly 135 located above is arranged upward and is not shielded, and the operator can directly adjust the elastic force of the first elastic assembly 135 by using common tools such as internal and external hex wrenches.

The second adjusting screw 1451 of the second elastic assembly 145 extends along the Y direction, and the operator can directly adjust it by using a nut wrench, which is convenient and efficient.

[0034] In a preferred embodiment, referring to Figure 2 , 6 , the dust collection mechanism 12 comprises a suction hood 121, at least one blowing pipe 122 and an angle adjusting assembly 123. The suction hood 121 is connected with an exhaust treatment system, which can be directly connected to the original equipment of the production workshop, and the dust is guided into the unified purification through the pipeline; the blowing pipe 122 is connected with a gas supply system, which can use the original compressed air source of the workshop or an independent air compressor to provide gas source for the blowing pipe 122. The blowing pipe 122 is installed in the box body 11 through the angle adjusting assembly 123 and is located between the suction hood 121 and the output port 112. The blowing pipe 122 is provided with an air outlet 1221 extending along the Y direction. When the blowing pipe 122 is one, it can be arranged above or below the glass fiber rod; when the blowing pipe 122 is two, the two blowing pipes 122 are arranged above and below the glass fiber rod respectively, and the blowing direction can be flexibly adjusted through the angle adjusting assembly 123, so that the compressed air is obliquely blown to the surface of the glass fiber rod away from the output port 112, the adhered dust is blown away and guided to the suction hood 121, and the dust flying out of the box body 11 is effectively avoided.

[0035] Preferably, the blowing pipe 122 is tapered towards the outside near the two side walls of the air outlet 1221, forming a narrow air outlet structure; it is beneficial to converge the airflow, improve the compressed air injection speed of the air outlet 1221, enhance the blowing force of the airflow on the surface dust of the glass fiber rod, and ensure that the attached dust is quickly blown away and directed to the air suction cover 121.

[0036] Specifically, referring to Figure 6 The angle adjusting assembly 123 includes a mounting seat 1231 fixed in the box body 11, a swing plate 1232 rotationally connected with the mounting seat 1231, and a locking piece for locking the angle of the swing plate 1232; wherein the locking piece is a bolt and a nut; the swing plate 1232 is provided with a long slot 1233 along the length direction thereof, the blowing pipe 122 is slidingly fitted with the long slot 1233 through a sliding seat, and the sliding seat is provided with a positioning bolt for fixing the position of the blowing pipe 122.

The two first guide rollers staggered form an adaptive gap for a single glass fiber rod to pass through independently, which gradually converges the multiple glass fiber rods to the middle while guiding the glass fiber rods to be conveyed stably forward, effectively reducing the width of the transverse arrangement of the glass fiber rods.

[0038] In the above, the second guide roller group 22 is a plurality of second guide rollers arranged along the Y direction at intervals, each second guide roller is rotatably mounted on the groove body 31 of the first impregnation tank 3 along the Z direction, and an adaptive gap for a single glass fiber rod to pass through independently is formed between adjacent two second guide rollers.

The two first transition rollers 32 and the two second transition rollers 33 are rotationally connected with the tank body 31. The two second transition rollers 33 are located below the two first transition rollers 32 in a lower region. Specifically, the roller surface of the second transition roller 33 is lower than the liquid surface of the primer coating agent in the tank body 31. After being guided, the glass fiber rod passes through one of the first transition rollers 32, the two second transition rollers 33 and the other first transition roller 32 in sequence, forming an S-shaped trajectory. The trajectory can completely immerse the glass fiber rod in the primer coating agent, and make the primer coating agent evenly spread along the surface of the glass fiber rod, avoiding local missing coating and uneven coating, and ensuring that the primer coating agent is evenly attached to the whole surface of the rod body, laying a foundation for subsequent face coating and curing of the primer coating agent.

The specific structure and working principle of the second impregnation tank 5 are not described again. The second impregnation tank 5 is used to uniformly coat the face coating agent on the plurality of glass fiber rods.

[0040] The first drying device 4 and the second drying device 6 both adopt a tunnel type drying furnace. The glass fiber rod passes through the tunnel type drying furnace in sequence to complete the curing of the primer coating agent and the face coating agent. The length of the tunnel type drying furnace should be determined by the conveying speed of the glass fiber rod and the drying and curing time. The drying device in the drawings only serves as an illustration. In addition, the tunnel type drying furnace belongs to the prior art, and the specific structure and working principle are not described again.

[0041] In a preferred embodiment, referring to Figure 8 The traction device 8 further comprises a third bracket 82, two transmission gears 83 coaxially fixed with the two traction rollers 81 respectively, and a first driving motor 84 arranged on the third bracket 82. The two transmission gears 83 are engaged, and the output shaft of the first driving motor 84 is in transmission connection with one of the transmission gears 83. The two traction rollers 81 are driven to rotate synchronously and reversely through the gear engagement, forming a clamping and conveying combined force. The outer periphery of the traction roller 81 is provided with a plurality of third annular grooves 811 arranged along the Y direction. The third annular grooves 811 are matched with the glass fiber rod, and the third annular grooves 811 on the two traction rollers 81 are aligned one by one along the Z direction, forming a clamping and conveying channel for the single glass fiber rod to pass through independently. Through the above arrangement, the rod body is prevented from deviating, moving or interfering with each other during clamping and conveying. At the same time, the traction rollers 81 rotating synchronously and reversely provide stable and uniform clamping force, and the third annular grooves 811 provide limiting and abutting, realizing synchronous and stable clamping and conveying of the plurality of glass fiber rods.

[0042] In the embodiment, referring to Figure 9The frame body 91 is provided with two second guide rails 911 extending along the Y direction, the lower mold 94 is in sliding connection with the second guide rails 911, and the lower mold 94 is provided with a handle 943 facilitating pushing and pulling. In the embodiment, the handle 943 is in T-shaped structure.

[0043] In a preferred embodiment, referring to Figure 9 、 10 The cutting and molding device 9 further comprises a fixed stop edge 96 and a floating stop block 97, which cooperate to lock the lower mold 94 directly below the upper mold 93. Specifically, the fixed stop edge 96 is fixedly arranged on the frame body 91 and located directly below the side of the upper mold 93 away from the handle 943, thereby forming a limit reference in the pushing direction of the lower mold 94. The floating stop block 97 is arranged on the frame body 91 below the side of the upper mold 93 close to the handle 943 and can float up and down. The floating stop block 97 is provided with two symmetrical guide surfaces 971 on the surface thereof, and the guide surfaces 971 are inclined along the Y direction. The bottom of the lower mold 94 is provided with a positioning groove 941 matched with the floating stop block 97. When the lower mold 94 is pushed in along the second guide rail 911, the bottom of the lower mold 94 touches the inclined guide surfaces 971 of the floating stop block 97, thereby pressing the floating stop block 97 to retract into the frame body 91 and allowing the lower mold 94 to smoothly pass through the area of the floating stop block 97. When the lower mold 94 is pushed into place, the front end of the lower mold 94 abuts against the fixed stop edge 96, and at this time, the positioning groove 941 is just moved to directly above the floating stop block 97, the floating stop block 97 is popped out and clamped into the positioning groove 941 to complete the locking. Similarly, when the lower mold 94 is pulled out, the edge of the positioning groove 941 presses the guide surfaces 971, thereby pressing the floating stop block 97 to unlock, and the lower mold 94 can be smoothly pulled out. Through the above arrangement, the automatic positioning and locking of the lower mold 94 are realized, and the deviation during molding is avoided.

[0044] Specifically, referring to Figure 10 The frame body 91 is provided with a first mounting hole 912 corresponding to the floating stop block 97, the floating stop block 97 is in sliding connection with the first mounting hole 912, the bottom of the floating stop block 97 is provided with a second mounting hole 972, the second mounting hole 972 is sleeved with a fourth spring 973, and the two ends of the fourth spring 973 are in abutment with the inner bottom of the first mounting hole 912 and the inner top of the second mounting hole 972, respectively. During the entire use process, the fourth spring 973 always maintains an elastic supporting state, which can provide a reset force for the floating stop block 97 to ensure that the floating stop block 97 is quickly popped out and clamped after the lower mold 94 is in place, and can smoothly contract when the lower mold 94 is pushed and pulled, thereby realizing smooth and efficient locking and unlocking actions.

[0045] In a preferred embodiment, referring to Figure 9The cutting mechanism 95 includes a second lifting assembly 951 mounted on the frame 91 and a cutter 952 mounted on the output end of the second lifting assembly 951, with the blade of the cutter 952 corresponding to the input end of the pressing cavity 942. When multiple fiberglass rods need to be cut simultaneously, the second lifting assembly 951 drives the cutter 952 to move upward rapidly, forming a shearing engagement with the edges of the upper mold 93 and the lower mold 94 through the blade, thus completing the cutting operation of all fiberglass rods simultaneously in one go.

[0046] In the above description, both the upper mold 93 and the lower mold 94 are equipped with heating devices, which consist of several electric heating rods evenly embedded in the pre-set mounting holes of the upper mold 93 and the lower mold 94. This ensures that heat is quickly and evenly transferred to the pressing cavity 942 and the working surface of the upper mold 93. The function of the heating devices is to regulate the temperature of the pressing cavity 942 and the upper mold 93 during the molding process, allowing the first rubber sheet and the second rubber sheet laid in the pressing cavity 942 to soften due to heat, thereby improving their fit with the intermediate fiberglass rod. At the same time, the upper mold 93 moves smoothly downward under the drive of the first lifting component 92, applying uniform and stable pressure to the three-layer structure of "first rubber sheet-fiberglass rod-second rubber sheet" in the pressing cavity 942, so that the softened rubber sheet and the fiberglass rod are fully bonded and tightly adhered, ultimately completing the integrated molding. The heating devices are not shown in the accompanying drawings.

[0047] In a preferred embodiment, see [reference] Figure 9 The system also includes a translation device 10. Two cutting and molding devices 9 are configured. The translation device 10 includes a base 101, a movable table 102, a lead screw module 103, and a second drive motor 104. The base 101 has several first guide rails 105 extending along the Y direction. The movable table 102 is slidably connected to the first guide rails 105. The second drive motor 104 drives the movable table 102 to move along the first guide rails 105 via the lead screw module 103. Both cutting and molding devices 9 are mounted on the movable table 102. Driven by the translation device 10, the two cutting and molding devices 9 work alternately. When one cutting and molding device 9 moves to the work station for molding, the other cutting and molding device 9 is simultaneously in the waiting position, completing the cooling and removal of the molded composite component, as well as the laying and preparation of the new first rubber sheet. This alternating operation mode eliminates the need to wait for a single molding process to complete before starting preparation, shortening the process interval and improving overall production efficiency.

[0048] Preferably, see Figure 9The two cutting and molding devices 9 share a frame 91, which includes a base plate 913, a middle plate 914, an upper plate 915, and four columns 916 connecting the base plate 913, the middle plate 914, and the upper plate 915, forming a stable frame structure. The second guide rail 911, the cutting mechanism 95, the fixed stop 96, and the floating stop 97 are all mounted on the middle plate 914, and the first lifting assembly 92 is mounted on the upper plate 915. Simultaneously, the cut end of the fiberglass rod is located between the four columns 916 to avoid positional interference between the columns 916 and the fiberglass rod when the translation device 10 drives the movable table 102 to switch the positions of the two cutting and molding devices 9, ensuring smooth switching operations and rod transport.

[0049] In a preferred embodiment, see [reference] Figure 2 , 8 It also includes an auxiliary support mechanism 20 for supporting the fiberglass rods. The auxiliary support mechanism 20 includes a fourth bracket 201, a floating frame 202, and a support roller 203. The fourth bracket 201 is located between the traction device 8 and the cutting and molding device 9. The floating frame 202 is slidably connected to the fourth bracket 201 along the Z-direction, and several third springs 204 are provided between the floating frame 202 and the fourth bracket 201. The support roller 203 is rotatably connected to the floating frame 202 and is used to support all the fiberglass rods. The function of the auxiliary support mechanism 20 is to support the ends of the multiple cut fiberglass rods, preventing them from drooping downwards due to suspension, and ensuring that they can be smoothly pushed above the first rubber sheet in the pressing cavity 942 during the next operation. Specifically, the upper surface of the support roller 203 is set to be slightly higher than or flush with the upper surface of the first rubber sheet placed in the pressing cavity 942, ensuring that the glass fiber rod is pushed without height obstruction and with a regular posture. At the same time, multiple third springs 204 are set to give the support roller 203 elastic buffering capacity. When the cutting and molding device 9 performs molding operation, the upper mold 93 presses down and drives the glass fiber rod to move downward. The support roller 203 shifts downward synchronously under the pressure of the rod, which does not affect the application of pressure and forming of molding, and can always maintain close support to the rod. After molding is completed, the third springs 204 reset and drive the support roller 203 back to the initial height, preparing for the next operation.

[0050] Further, see Figure 8The auxiliary support mechanism 20 also includes a third lifting component 205, and a fourth bracket 201 is located at the output end of the third lifting component 205. The third lifting component 205 can drive the fourth bracket 201 to move up and down along the Z-axis, thereby driving the support roller 203 to move up and down synchronously. When the two cutting and molding devices 9 need to switch positions, the third lifting component 205 first drives the fourth bracket 201 to move upward, causing the support roller 203 to lift the ends of all the glass fiber rods and swing them upward a short distance, so that the ends of the rods are separated from the side walls of the upper mold 93 and the lower mold 94. This avoids the positional shift caused by the contact friction between the ends of the glass fiber rods and the side walls of the mold body during the position exchange of the cutting and molding devices 9, ensuring that the rods always maintain a regular posture, and providing a guarantee for the accuracy of subsequent pushing to the pressing cavity 942 and molding operations.

[0051] In the above, the first lifting component 92, the second lifting component 951 and the third lifting component 205 can be cylinders, electric cylinders or other lifting mechanisms to ensure that the upper mold 93, the cutter 952 and the support roller 203 lift smoothly.

[0052] Please see Figure 11 The present invention also provides a molding method for a composite component for a non-pneumatic tire support leg, which is applied to the molding equipment for the composite component for the non-pneumatic tire support leg; the molding method includes: S1. Multiple fiberglass rod rolls are unwound by an unwinding device. The multiple fiberglass rod rolls pass sequentially through a grinding device 1, a first guide roller group 21, a second guide roller group 22, a first impregnation tank 3, a first drying device 4, a second impregnation tank 5, a second drying device 6, and a traction device 8.

[0053] In this embodiment, multiple fiberglass rods are transported in an orderly manner under the traction of the traction device 8: first, the outer surface of each rod is polished by the grinding device 1 to increase the surface roughness and improve the adhesion of the subsequent adhesive; then, they are successively gathered by the first guide roller group 21 and the second guide roller group 22 to gradually reduce the lateral arrangement width, and finally match the preset arrangement width of the composite component; next, they are uniformly coated with a base coating adhesive in the first impregnation tank 3, and the base coating adhesive is dried and cured by the first drying device 4. Then, they are coated with a top coating adhesive in the second impregnation tank 5, and the top coating adhesive is cured by the second drying device 6, thereby strengthening the bonding effect between the fiberglass rod and the rubber sheet; finally, the traction device 8 transports the multiple fiberglass rods that have been surface-treated, double-impregnated and cured, and arranged in a regular manner to the front end of the cutting and molding device 9 to prepare for subsequent processes.

[0054] S2. Place the first rubber sheet into the pressing cavity 942 of the lower mold 94. At this time, the lower mold 94 is in the waiting position. The operator can use manual method or cooperate with the robot to realize the automated operation, and lay the first rubber sheet flat in the preset position of the pressing cavity 942.

[0055] S3. Push the lower mold 94 into the lower mold 93 along the Y direction. In this embodiment, the operator pushes the handle 943 of the lower mold 94 along the Y direction to push the lower mold 94 from the waiting station to the working station, that is, directly below the upper mold 93. After being pushed into place, the front end of the lower mold 94 is tightly abutted against the fixed stop edge 96, and the rear end is automatically locked in position by the floating stop block 97.

[0056] S4. The traction device 8 is activated, pulling multiple fiberglass rods forward along the X direction until they are above the first rubber sheet. In this embodiment, the first drive motor 84 outputs power, which drives the upper and lower traction rollers 81 to rotate synchronously in opposite directions through two meshing transmission gears 83, forming a stable clamping force. The third annular groove 811 on the outer periphery of the traction roller 81 is adapted to each fiberglass rod. Under the clamping and limiting action, the multiple fiberglass rods are pulled forward smoothly along the X direction to achieve fixed-length conveying until the front end of the rod is laid above the first rubber sheet, and the overall length meets the molding requirements.

[0057] S5. Place the second rubber sheet on top of all the fiberglass rods. In this embodiment, the operator can manually or automatically place the second rubber sheet on top of all the fiberglass rods, forming a three-layer structure of "first rubber sheet - fiberglass rod - second rubber sheet".

[0058] S6. The first lifting component 92 drives the upper mold 93 to move downward. The upper mold 93 and the pressing cavity 942 of the lower mold 94 cooperate to press the first rubber sheet, multiple glass fiber rods, and the second rubber sheet into a composite component. At this time, the electric heating rods in the upper mold 93 and the lower mold 94 have heated the lower surface of the upper mold 93 and the pressing cavity 942 of the lower mold 94 to the preset molding temperature, so that the first rubber sheet and the second rubber sheet continue to soften to improve the fit. At the same time, the upper mold 93 applies uniform and stable pressure and holds the pressure for a period of time to tightly press the three-layer structure together, finally forming a composite component with a dense structure and strong interlayer bonding.

[0059] S7. The cutting mechanism 95 is activated to cut multiple fiberglass rods. In this embodiment, the second lifting component 951 drives the cutter 952 to move upward. The blade of the cutter 952 extends along the Y direction and forms a shearing engagement with the edge sides of the upper mold 93 and the lower mold 94, cutting all fiberglass rods simultaneously in one go. The ends of the remaining fiberglass rods after cutting are supported by the auxiliary support mechanism 20, reserving neat ends for the next conveying operation.

[0060] S8, the first lifting component 92 drives the upper mold 93 to move upward and reset.

[0061] S9. Pull the lower mold 94 out along the Y direction, moving it away from the upper mold 93. In this embodiment, after the composite component molding and glass fiber rod cutting are completed, the operator pulls the handle 943 of the lower mold 94 in the opposite direction along the Y direction. When the lower mold 94 moves, its positioning groove 941 presses against the floating stop 97, causing it to unlock automatically. Then, continue pulling the lower mold 94 to smoothly pull it out of the work station, away from the upper mold 93, and back to the waiting station.

[0062] S10. Remove the laminated composite component. In this embodiment, after the lower mold 94 returns to the waiting station, and the composite component cools to a suitable temperature (to avoid burning or deformation), the laminated composite component can be removed from the lamination cavity 942 of the lower mold 94 by manual operation or with the aid of a robotic arm. After removal, the composite component is placed in a designated storage area, and residual impurities in the lamination cavity 942 are cleaned to prepare for the next round of placing the first rubber sheet and starting new operations.

[0063] In another embodiment, the two cutting and molding devices 9 are driven by the reciprocating motion of the translation device 10 to achieve alternating switching between the working station and the waiting station. The specific alternating working logic is as follows: In the initial state, one cutting and molding device 9 is located directly below the upper mold 93 at the working station, while the other is in the waiting station. At this time, the cutting and molding device 9 at the working station has already completed the S2-S3 processes (laying the first rubber sheet and positioning the mold) at the waiting station. After entering the working station, it simultaneously carries out the S4-S7 processes (feeding the rod, laying the second rubber sheet, molding, and cutting the rod). At the same time, the cutting and molding device 9 at the waiting station simultaneously completes the S8-S10 processes (resetting the upper mold 93, unlocking the mold, and cleaning the part), and prepares in advance for the S2-S3 processes of the next round of work.

[0064] After the cutting and molding device 9 at the waiting work station completes the S7 cutting operation, the translation device 10 is activated. The second drive motor 104 outputs power through the lead screw module 103, driving the movable table 102 to move smoothly along the first guide rail 105, moving the cutting and molding device 9 to the waiting work station. At the same time, the other cutting and molding device 9, which has completed its preparation, is precisely pushed to the work station. It is worth noting that during the movement, the third lifting component 205 of the auxiliary support mechanism 20 will synchronously drive the support roller 203 to move upward, lifting the end of the glass fiber rod away from the mold side wall, effectively preventing the rod from shifting position due to contact friction.

[0065] The newly moved cutting and molding device 9 immediately performs the S4-S7 processes; at the same time, the newly moved cutting and molding device 9 to the waiting station completes the S8-S10 processes and simultaneously advances the preparation for the S2-S3 processes of the next round of work.

[0066] After the cutting and molding device 9 at the current work station completes the molding and cutting operations, the translation device 10 reverses the drive and switches the work stations of the two cutting and molding devices 9 again, forming a "work-preparation" cyclical alternation mode, ultimately achieving continuous production and greatly improving overall work efficiency.

[0067] It is understood that those skilled in the art can make equivalent substitutions or modifications to the technical solution and inventive concept of the present invention, and all such substitutions or modifications should fall within the protection scope of the appended claims.
