Description

Technical Field

[0001] This utility model relates to the field of automated production equipment technology, and in particular to an automated production line for hot pressing of carbon fiber products. Background Technology

[0002] Carbon fiber products are increasingly used in aerospace, automobile manufacturing, and sporting goods due to their excellent properties of being lightweight and having high strength. Hot pressing is a key process in the manufacture of carbon fiber products, and its production efficiency and automation level directly affect the cost and quality of the products. Automated hot pressing production lines typically include feeding, transportation, hot pressing, and unloading processes, and the entire production process is connected through automated equipment to improve production efficiency.

[0003] In actual production, in order to meet the needs of different products, it is often necessary to process molds of different sizes. When switching between different specifications of molds, the width of the conveyor track or channel of the existing production line mostly needs to be manually adjusted by stopping the machine. Operators need to manually measure, loosen fasteners, move the track, and then tighten it again. This process is not only tedious and time-consuming, but the adjustment accuracy also depends on human experience, which is prone to errors and affects the accuracy of subsequent processes. This greatly limits the flexibility and rapid response capability of the production line and has become a bottleneck to improving overall production efficiency.

[0004] For safety reasons, guardrails are usually installed around automated production lines to isolate the work area. However, the existing guardrails are often assembled in a simple way, mostly by directly overlapping or using simple pins. This connection method is not stable enough, and the guardrails are easily bumped or moved by unauthorized personnel, which leads to the failure of safety isolation and creates serious safety hazards. This cannot meet the strict requirements of modern factories for safe production.

[0005] Therefore, this utility model proposes an automated production line for hot pressing of carbon fiber products to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the automated production line for hot pressing of carbon fiber products, such as the inability to automatically adapt to molds of different sizes, resulting in low production changeover efficiency, and the unstable splicing structure of guardrails posing safety hazards, this utility model aims to provide an automated production line for hot pressing of carbon fiber products with an improved structure that can effectively solve the above problems.

[0007] This utility model provides an automated production line for hot pressing of carbon fiber products, including: a hot press, a conveyor table, two conveying systems installed on the conveyor table, an adjustment mechanism, and a control center.

[0008] The adjustment mechanism includes a motor, a bidirectional lead screw, a fixed block, a detection device, and a signal receiver.

[0009] Furthermore, the fixed block, the conveying system, and the bidirectional lead screw are combined by means of threaded engagement between the fixed block and the bidirectional lead screw, and by means of rigid connection between the fixed block and the conveying system. The control center controls the motor to drive the bidirectional lead screw to rotate via the signal receiver.

[0010] Preferably, the control center performs precise fine-tuning of the motor based on the mold size data detected by the detection device.

[0011] Preferably, the adjustment mechanism further includes a telescopic block that extends and retracts synchronously with the transport system to provide support and limit, and a support platform disposed at the bottom of the transport platform to support the transport system.

[0012] Preferably, the production line further includes a lifting device, a pushing device, and a finished product table; wherein the pushing device includes a telescopic device that is telescopically connected thereto and used to engage with the mold.

[0013] Preferably, the production line further includes at least two guardrails interconnected by a locking mechanism; the locking mechanism includes a locking box disposed on one of the guardrails and a locking pin installed through a mounting hole opened in the other guardrail.

[0014] Preferably, the locking box is provided with a latch that mates with the locking groove of the locking post, a spring that provides a return force to the latch, a sliding piece fixed to the latch, and an unlocker.

[0015] Preferably, the locking box is further provided with a limiting block and a limiting groove for limiting the movement path of the sliding piece.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problems of existing production lines being unable to automatically adapt to molds of different sizes, requiring manual adjustment, which is time-consuming, has low precision, and low production efficiency. By setting up an adjustment mechanism that links a motor, a bidirectional lead screw, and a detection device, and using closed-loop control by the control center, it achieves the technical effect of quickly and accurately adaptively adjusting the distance between transport platforms, significantly shortening the preparation time for changing product specifications, and improving the automation level and production efficiency of the production line. 2. This utility model solves the problem that most existing guardrails are simply spliced ​​together, resulting in weak connections and easy movement by unauthorized personnel, thus creating safety hazards. It achieves the technical effect of stable and reliable connection between guardrails, convenient and quick assembly and disassembly, effectively preventing the guardrails from being accidentally moved, and improving the safety of the production site. 3. This utility model solves the problems of cumbersome hot pressing process, reliance on manual operation, and discontinuous overall process of traditional carbon fiber products by integrating the adaptive adjustment mechanism, lifting device, pushing device, and hot press into an integrated design and automated control. It achieves full automation from mold conveying, adjustment, hot pressing to finished product unloading, with a compact structure, stable operation, and improved product quality consistency.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] Example: Please refer to Figures 1 to 5 This utility model provides an automated production line for hot pressing of carbon fiber products, which aims to solve the problems of low production efficiency caused by the inability of the production line to automatically adapt to different mold sizes and the safety hazards caused by the unstable splicing structure of the guardrail 9 in the existing technology.

[0021] like Figure 1 As shown, an automated production line for hot pressing of carbon fiber products includes a control center 1, a transport platform 7, a hot press 4, a pushing device 5, a lifting device 8, and a finished product platform 10. The transport platform 7 is used to transport the mold to the hot press 4. The hot press 4 hot presses the mold. The hot-pressed mold is then transported to the finished product platform 10 via the transport platform 7. The pushing device 5 and the lifting device 8 work together to transfer the mold between the transport platform 7 and the hot press 4. The control center 1 is electrically connected to and controls the operation of each device on the production line. A guardrail 9 is also installed around the production line for safety isolation.

[0022] To solve the above-mentioned technical problems, the technical solution of this embodiment is that an automated production line for hot pressing of carbon fiber products further includes an adjustment mechanism 2, and the adjustment mechanism 2 forms a specific structural cooperation and connection relationship with the transport table 7 and the two transport systems 201 on the transport table 7.

[0023] Please refer to the following carefully. Figure 2 and Figure 3The adjustment mechanism 2 includes a motor 206, a bidirectional lead screw 205, fixed blocks 203, a detection device 204, and a signal receiver 207. The signal receiver 207 is electrically connected between the control center 1 and the motor 206 to receive adjustment commands from the control center 1. The output shaft of the motor 206 is rotatably connected to the bidirectional lead screw 205. Two fixed blocks 203 are threaded onto the bidirectional lead screw 205. Each fixed block 203 is rigidly connected to a corresponding conveying system 201. The rotation of the motor 206 is converted into linear opposing or disjoint motion of the two fixed blocks 203 through the bidirectional lead screw 205, thereby driving the two conveying systems 201 to adjust synchronously. The spacing adjustment mechanism is designed to provide an adaptive conveying channel for different mold models. The detection device 204 is fixed on the top of the conveying platform 7 and is used to scan the mold size in real time and feed the data back to the signal receiver 207. Finally, the control center 1 makes precise fine adjustments to the motor 206 based on the feedback data. This structure, which combines detection feedback with drive control, ensures that the spacing of the conveying system 201 can be matched with the mold with high precision. To further improve the structural stability, the adjustment mechanism 2 also includes a telescopic block 202 that extends and retracts synchronously with the conveying system 201 to provide support and limit, and a support platform 208 set at the bottom of the conveying platform 7 to support the conveying system 201.

[0024] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, please refer to Figure 1 The production line also includes a lifting device 8 and a pushing device 5. After the conveyor table 7 transports the mold to the front of the hot press 4, the lifting device 8 lifts the mold to a height level with the pressure port of the hot press 4, and the pushing device 5 pushes the mold into the hot press 4. After the hot pressing is completed, the pushing device 5 pulls the mold back, the lifting device 8 descends, and puts the mold back on the conveyor table 7. The pushing device 5 includes a telescopic device 6 that engages with the mold. The telescopic device 6 extends and retracts to push and pull the mold.

[0025] In another preferred embodiment, the production line also includes at least two guardrails 9 interconnected by a locking mechanism 3. The locking mechanism 3 includes a locking box 301 and a locking post 308 disposed on the guardrail 9. Please refer to [reference needed]. Figure 4 and Figure 5 The locking pin 308 is fixedly installed on the guardrail 9 through the mounting hole 309. When the locking pin 308 is inserted into the locking box 301, the locking tongue 307 inside the locking box 301 is engaged in the locking groove of the locking pin 308 under the elastic force of the spring 303, thus completing the locking.

[0026] As another preferred embodiment, please refer to Figure 4 and Figure 5The locking mechanism 3 also includes a sliding piece 304 and an unlocker 302. The sliding piece 304 is fixedly connected to the latch 307, and the unlocker 302 is drivenly connected to the sliding piece 304. When unlocking is required, the unlocker 302 is pulled upward to drive the sliding piece 304 to move, thereby causing the latch 307 to disengage from the locking groove of the locking post 308. The locking box 301 is also provided with a limit block 305 and a limit groove 306 to limit the movement path of the sliding piece 304.

[0027] Working Principle: First, the operator inputs the target product model into the control center 1. The control center 1 generates an adjustment command based on preset parameters and transmits it to the signal receiver 207, triggering the motor 206 to start. The rotation of the motor 206 drives the fixed block 203 to rotate synchronously. Since the bidirectional lead screw 205 is threadedly engaged with the fixed block 203, and the top of the lead screw is rigidly connected to the conveying system 201, its rotation is converted into the opposite or reverse translation of the conveying system 201, directly adjusting the spacing of the conveying platform 7 to adapt to different mold models. The mold moves between the two conveying systems 201, completing the adjustment of the conveying system 201. At the same time as the adjustment, the telescopic block 202 also extends and retracts, providing support and limiting for the conveying system 201. The support platform 208 set at the bottom of the conveying platform 7 can support the conveying system 201, ensuring the load-bearing capacity of the conveying system 201 and preventing structural shaking after adjustment. At the same time, the detection device 204 fixed on the top of the conveying platform 7 scans the shape of the mold in real time. The size data is fed back to the signal receiver 207, and the control center 1 drives the motor 206 to make precise fine adjustments to ensure that the mold and the conveying system 201 fit perfectly, solving the error problem of manual adjustment. When the product enters the conveying table 7, it will be transported to the front of the pushing device 5 along with the conveying table 7. When the mold enters the conveying table 7, it will be moved to the front of the pushing device 5 along with the conveying system 201. After the detection device 204 confirms the mold position for the second time, the control center 1 commands the lifting device 8 to rise, lifting the mold to be level with the pressure port of the hot press 4. Then the pushing device 5 will extend and retract. The extension and retraction device 6 engages with the mold and pushes the mold into the hot press 4. After the hot press is completed, the extension and retraction device 6 retracts, thereby driving the mold back to its original position. The lifting device 8 retracts, driving the mold back to the conveying system 201 and then transporting it to the finished product table 10 for further processing by employees. The adjustment mechanism 2 solves the problem that the existing equipment cannot adaptively adjust the size of the stationary mold, which makes it impossible to quickly switch product specifications for production. Furthermore, when arranging the guardrail 9, first install the locking pin 308 in the pre-drilled mounting hole 309 in the appropriate direction of the guardrail 9. Then, align one side of the locking box 301 of another guardrail 9 with the locking pin 308 and merge them together. When the locking pin 308 enters the locking box 301, it will press the locking tongue 307, causing the sliding piece 304 fixed to the locking tongue 307 to move vertically stably under the limitation of the limiting block 305 and the limiting groove 306, compressing the spring 303 until the locking pin 308 reaches the appropriate position, and the locking tongue 307 engages with the locking pin 308. When the locking groove of the post 308 is aligned, the spring 303 expands and recovers, pushing the locking tongue 307 and the sliding plate 304 into the locking post 308 to complete the locking. When disassembly is required, simply pull the unlocker 302, and the sliding plate 304 will drive the locking tongue 307 to disengage from the locking post 308 to unlock. When the unlocker 302 is released, the locking tongue 307 will return to its original position under the action of the spring 303 to complete the unlocking. The locking mechanism 3 solves the problem that most existing guardrails 9 do not have a locking structure, which makes the guardrails 9 easy for unauthorized personnel to move, thus creating a safety hazard.
