[0032] A cleaning device C2 is arranged on the side surface of the support frame C101. The cleaning device C2 includes a second motor C201. The second motor C201 is fixedly connected to the side surface of the support frame C101. The output shaft of the second motor C201 is fixedly connected with a reciprocating lead screw C202.

[0034] The cleaning device C2 includes a buffer structure. The buffer structure includes a fixing plate C209. The fixing plate C209 is arranged on the side surface of the support frame C101. A protective shell C210 is fixedly connected to the top of the fixing plate C209. A fixing block C211 is fixedly connected to the top of the protective shell C210.

[0035] The positioning block C214 runs through the top of the mounting plate C215. The number of mounting blocks C216 is set to two and they are symmetric with respect to the vertical central axis of the protective shell C210. When the seat backrest falls onto the top of the mounting plate C215, under the action of the impact force, the downward movement of the mounting plate C215 and the mounting blocks C216 will cause the compression of the third spring C213.

[0036] The top of the fixed block C211 is fixedly connected to the third spring C213. The end of the third spring C213 away from the fixed block C211 is fixedly connected to the bottom of the mounting plate C215. The initial state of the third spring C213 is a relaxed state.

[0039] Compared with the prior art, the forming and processing equipment for the automotive seat backrest of Embodiment 1 has the following advantages: Through the mutual cooperation of the downward displacement force of the mounting plate and the mounting blocks under the impact force and components such as the positioning block, damper, buffer spring and third spring in the cleaning device, not only the effective absorption of the impact force is achieved, but also through the compression and reaction force of the spring, the vibration energy is converted into elastic potential energy, and the reaction force generated by the spring in the opposite direction of the vibration is used to offset the action of the vibration force. This design not only achieves the buffering effect, but also significantly reduces the offset, deformation or error caused by vibration, thus greatly improving the processing accuracy and consistency of the seat backrest. In addition, through the precise cooperation of the force of the motor driving the reciprocating lead screw to rotate and components such as the cleaning roller, gear and rotating rod in the cleaning device, the automatic cleaning of the conveyor belt is realized, effectively removing the dirt on the conveyor belt and avoiding the influence of the dirty surface of the conveyor belt on the processing accuracy and quality of the seat backrest. These innovative designs together ensure the quality of each product during the production process, improving the overall production efficiency and product competitiveness.

[0040] Embodiment 2 Based on Embodiment 1, a specific application of this embodiment is: Start the first motor B34. The forward rotation of the first motor B34 drives the forward rotation of gear B35. The forward rotation of gear B35 can drive the movement of rack B37, enabling rack B37 to slide on the top of cross plate B36. The sliding of rack B37 drives the movement of short rod B38 and electric fan B39. The electric fan B39 drives the rotation of the fan blades through a motor, and the rotation of the fan blades generates wind, which blows and cools the lower mold B2 of the car seat backrest and the upper mold B32 of the car seat backrest. The electric fan B39 moves along with rack B37, enabling mobile blowing and heat dissipation. Moreover, this car seat backrest mold assembly is made of high-quality alloy material, featuring high wear resistance and long service life, ensuring stability and reliability during continuous production. The electric fan B39 moves along with rack B37, allowing the wind to act evenly and continuously on different parts of the mold assembly. Through directional blowing, it effectively helps the mold cool down quickly, preventing the material from deforming or being adversely affected due to overheating or local high temperature during the molding process. Especially in a high-temperature environment, this heat dissipation design can reduce heat accumulation and ensure the consistency of the temperature inside and outside the mold. The mold assembly is made of high-quality alloy material, which has high wear resistance and corrosion resistance, can maintain good performance during long-term and high-intensity use, and reduce the maintenance frequency and replacement cost.

[0041] When rack B37 moves, it drives the movement of extrusion rod B44. Displacement block B42 is located on the movement trajectory of extrusion rod B44. When extrusion rod B44 moves, it will squeeze displacement block B42, driving displacement block B42 to slide along long rod frame B41. The sliding of displacement block B42 drives the movement of connecting rod B43 and scraping rod B45. Scraping rod B45 is located on the side of the lower mold B2 of the car seat backrest. When scraping rod B45 moves, it will scrape the side of the lower mold B2 of the car seat backrest, scraping off the solution that overflows from the lower mold B2 of the car seat backrest due to stamping. The movement of extrusion rod B44 drives scraping rod B45 to scrape the side of the lower mold B2 of the car seat backrest, which can effectively scrape off the solution that overflows due to the stamping process. This helps to keep the mold clean, prevent the solution from accumulating inside the mold, and avoid affecting the subsequent molding quality. If the overflow of the solution is not cleared in time, it may cause pollution and affect the accuracy of the next molding and the service life of the mold. Through the coordinated movement of displacement block B42 and scraping rod B45, the overflowing solution can be automatically cleaned, reducing the pollution risk and ensuring the cleanliness during the production process.

[0042] The reciprocating lead screw C202 is driven to rotate by the second motor C201, and then the rotation of the reciprocating lead screw C202 drives the threaded block C203 to displace. The threaded block C203 is limited by the limiting rod C204 on the side of the threaded block C203. Then, the displacement of the threaded block C203 drives the rotating rod C205 to displace. The rotation of the rotating rod C205 drives the cleaning roller C207 to displace, and the rotation of the rotating rod C205 drives the gear C206 to displace, so that the gear C206 meshes with the rack C208 to rotate. Then, the rotation of the gear C206 drives the rotating rod C205 to rotate, and the rotation of the rotating rod C205 drives the cleaning roller C207 to rotate, realizing the function of cleaning the conveyor belt C102 by rotating during the displacement of the cleaning roller C207. The seat backplate is fed through the buffer plate C104. When the seat backplate falls on the top of the mounting plate C215, the mounting plate C215 and the mounting block C216 are displaced downward by the impact force. The third spring C213 and the buffer spring C218 at the bottom of the mounting plate C215 are compressed. The vibration energy is converted into elastic potential energy by the compression of the third spring C213 and the buffer spring C218. The third spring C213 generates a reaction force opposite to the vibration direction to offset the vibration force, realizing the buffering function.

[0043] The forming and processing equipment for the automotive seat backrest in Embodiment 2 has the following advantages compared with the prior art: The first motor B34 drives the gear B35 to rotate, and then the gear B35 drives the rack B37 to slide. This mechanical transmission method not only has a simple structure but also a high transmission efficiency, ensuring that the electric fan B39 can move stably and accurately to the designated position to blow and dissipate heat evenly on the mold assembly. At the same time, the mobile design of the electric fan B39 makes the heat dissipation effect more flexible and efficient. It can adjust the blowing position and range according to the actual temperature distribution of the mold, thereby achieving more precise temperature control management. In addition, the movement of the electric fan B39 also drives the movement of the extrusion rod B44, which in turn drives the scraping rod B45 to scrape and clean the side of the mold. This linkage design not only improves the automation degree of the equipment but also effectively avoids the accumulation and pollution of the mold solution, ensuring the cleanliness and forming quality of the mold. In the cleaning device C2, the second motor C201 drives the reciprocating lead screw C202 to rotate, and then a series of transmission components drive the cleaning roller C207 to move and rotate, achieving a comprehensive cleaning of the conveyor belt C102. This design not only has a high cleaning efficiency but also can ensure the cleanliness of the conveyor belt surface, thus avoiding adverse effects on the processing accuracy and quality of the seat backrest. At the same time, the combined use of the third spring C213 and the buffer spring C218 in the buffer structure effectively absorbs the impact force and vibration generated when the seat backrest falls, reducing the damage to the mechanical system and the deformation error of the seat backrest itself, and improving the processing accuracy and consistency of the product. In summary, the forming and processing equipment for the automotive seat backrest in Embodiment 2 shows significant advantages in aspects such as heat dissipation, cleaning, and buffering, providing a strong technical guarantee for the high-efficiency and high-quality production of the seat backrest.

[0044] Embodiment 3 A forming and processing method for a forming and processing equipment of an automotive seat backrest: The method includes the following steps: First, place the sheet metal to be stamped on the automated conveying system at the front side of the process. The automated conveying system automatically transports the sheet metal into the stamping device. Then, start the stamping machine body B31. The stamping machine body B31 drives the upper die B32 of the car seat backrest to move downward to stamp and form the stamped part. After stamping, the upper die B32 of the car seat backrest rises and resets. The automated conveying system at the back side of the process automatically transports the stamped sheet metal to the next process, completing the entire processing procedure. During the stamping process, start the first motor B34. The first motor B34 drives the gear B35 to rotate. The gear B35 drives the rack B37 to slide on the cross plate B36. The rack B37 drives the short rod B38 and the electric fan B39 to move. The electric fan B39 blows air to cool the lower die B2 of the car seat backrest and the upper die B32 of the car seat backrest, preventing the die from overheating and causing material deformation or adverse effects. At the same time, when the rack B37 moves, it drives the extrusion rod B44 to move. The extrusion rod B44 pushes the displacement block B42 to slide within the long rod frame B41. The displacement block B42 drives the connecting rod B43 and the scraping rod B45 to move. The scraping rod B45 scrapes the side of the lower die B2 of the car seat backrest to remove excess die solution and keep the die clean. On the automated conveying system, start the second motor C201. The second motor C201 drives the reciprocating lead screw C202 to rotate. The reciprocating lead screw C202 drives the threaded block C203 to displace. The threaded block C203 drives the rotating rod C205 and the cleaning roller C207 to move and rotate. The cleaning roller C207 cleans the conveyor belt C102. The seat backrest falls onto the mounting plate C215 through the buffer plate C104. The mounting plate C215 and the mounting block C216 are displaced downward under the impact force. The third spring C213 and the buffer spring C218 are compressed, converting the vibration energy into elastic potential energy to achieve a buffering effect and protecting the seat backrest and the mechanical system from damage. Through this method, the automated forming processing of the car seat backrest can be realized, improving production efficiency and product quality.

[0045] The forming and processing method of the automotive seat backrest forming and processing equipment in Embodiment 3 has the following advantages compared with the prior art: This method combines the multiple advantages of an automated conveying system, a stamping device, a heat dissipation device, a cleaning device, and a buffer structure, achieving the automated, efficient, and high-quality production of automotive seat backrests. During the entire processing process, the automated conveying system is responsible for automatically conveying the sheet material to be stamped into the stamping device, eliminating the need for manual handling, saving labor costs, and improving production efficiency at the same time. The stamping device is responsible for stamping and forming the sheet material to be stamped. Through precise stamping processes, it can ensure that the shape and dimensions of the seat backrest meet the design requirements. The heat dissipation device, through the mobile design of the electric fan, evenly blows air to dissipate heat from the die assembly, effectively preventing material deformation or adverse effects caused by overheating of the die, and ensuring the processing accuracy and quality of the seat backrest. The cleaning device drives the cleaning roller through a series of transmission components to comprehensively clean the conveyor belt, ensuring the cleanliness of the conveyor belt surface, thereby avoiding adverse effects on the processing accuracy and quality of the seat backrest. The buffer structure effectively absorbs the impact force and vibration generated when the seat backrest falls, reducing damage to the mechanical system and deformation errors of the seat backrest itself, and further improving the processing accuracy and consistency of the product. In addition, this method also has a high degree of flexibility and adjustability, and can be adjusted and optimized according to different production requirements to adapt to the production of seat backrests of different specifications and materials. In summary, the forming and processing method of the automotive seat backrest forming and processing equipment in Embodiment 3 shows significant advantages in terms of automation level, production efficiency, product quality, and flexibility, providing strong technical support for the efficient and high-quality production of automotive seat backrests.
