Description

Technical Field

[0001] The invention relates to the technical field of conductive foam production, and in particular to a conductive foam automatic lining core replacement device. Background Art

[0002] Conductive foam with a lining (hard core) is a composite material that combines conductivity and buffer protection functions. It plays an important role in the manufacture of modern electronic equipment. The technical origin of conductive foam can be traced back to the continuous improvement of the performance requirements of electronic materials. With the increasing miniaturization, integration and high performance of electronic equipment, the requirements for the conductivity, shielding, buffer protection and other properties of materials are becoming higher and higher. Conductive foam, as a new type of electronic material, combines conductive materials with foam materials to achieve the dual functions of conductivity and buffer protection, meeting the new needs of electronic equipment manufacturing. The lining (hard core) provides structural support and buffer protection for the conductive foam.

[0003] The following technical problems exist in the process of inserting or replacing the lining core (hard core) in the conductive foam:

[0004] When manually inserting or replacing the liner, it is necessary to ensure that the liner is correctly aligned during the insertion of the conductive foam. Conductive foam is becoming increasingly miniaturized, which requires operators to have higher skills and experience to avoid performance problems caused by size mismatch or position offset. Due to the limitations of manual operation, it may be difficult to achieve high-precision insertion and replacement requirements, especially in situations where fine alignment is required.

[0005] During the process of inserting and replacing the liner, if the operation is improper, the surface of the conductive foam may be scratched or damaged, affecting its conductive performance and appearance quality. In particular, when a person touches the surface of the conductive foam, the grease and dirt on the skin may be brought to the surface of the conductive foam, causing a certain degree of pollution. If the surface of the conductive foam is contaminated, it may affect its conductive performance and appearance. Therefore, the conductive foam needs to be cleaned regularly to keep it in good condition, which increases production costs.

[0006] The process of manually inserting or replacing the liner is relatively time-consuming, especially in large-scale production, which will seriously affect production efficiency; due to the complexity of the operation and the high skill requirements, the cost of manually inserting and replacing the liner is also relatively high; in addition, if the material is damaged or performance problems occur due to improper operation, additional costs will be added; manual operation also makes it difficult to ensure that the quality and effect of each insertion and replacement of the liner are completely consistent, which may affect the overall performance and stability of the product.

[0022] The present invention provides a conductive foam automatic lining core replacement device, which has the following beneficial effects:

[0023] 1) It is easy to operate and can achieve the requirements of high-precision alignment and insertion of the replacement liner, effectively avoiding the problem of artificial damage and contamination of the surface of the conductive foam, improving production efficiency, reducing production costs, ensuring that the quality and effect of each insertion and replacement of the liner are completely consistent, and improving the overall performance and stability of the product;

[0024] 2) The sensor component can detect signals in real time and transmit these signals to the controller. The controller accurately controls the coordinated actions of the conductive foam pressing drive component and the stepper motor according to the received signals, ensuring that the conductive foam is pressed up and the liner is transported and inserted into the conductive foam at the right time and position. The automated control achieves the requirements of high-precision alignment, insertion and replacement of the liner. This precise control ensures the accuracy and reliability of the process of inserting or replacing the liner;

[0025] The cooperation of the stepper motor and the telescopic core-changing assembly in the device improves the production efficiency of the device. The rotation speed and rotation angle are adjusted according to the needs, and the parameters are preset. After receiving the signal and controlling the rotation speed and rotation angle of the stepper motor, the liner core to be inserted on the insertion turntable is transported to the telescopic core-changing assembly, and then the telescopic core-changing assembly moves and extends and accurately inserts the liner core to be inserted into the conductive foam, thus realizing the precise insertion or replacement of the liner core;

[0026] Automatic insertion or replacement of the liner effectively reduces human intervention, effectively avoids contamination of the surface of the conductive foam by human hands, and reduces quality problems caused by improper or negligent manual operation; at the same time, by accurately controlling each link of the liner replacement, it can ensure that the liner in each conductive foam meets the predetermined standards and requirements, ensuring the consistency of the quality and effect of inserting and replacing the liner, and improving the overall performance and stability of the product;

[0027] 3) When the magnetic switch detects that the liner core to be inserted is transported to the liner core insertion groove on the telescopic core changing assembly, the telescopic core changing assembly will start the extension action, so that the liner core to be inserted moves toward the upper plate film through the liner core insertion groove, and is inserted into the liner core insertion through hole and the liner core insertion guide groove at a radial position on the turntable in sequence until it is accurately inserted into the conductive foam, providing a precise guide path for the new liner core after cutting, ensuring the precise transportation of the liner core to be inserted into the conductive foam.

[0028] 4) The automatic driving stepper motor drives the turntable to rotate, and the cut liner core inserted into the through hole at a radial position on the turntable can be quickly and accurately transported to the telescopic core replacement assembly, and at the same time, a new cut liner core is inserted into the through hole at another radial position on the turntable, and the above steps are repeated to realize the uninterrupted insertion or replacement of the cut liner core, thereby ensuring the continuity of the production process and improving the efficiency of the overall production line;

[0029] The cutting core assembly is arranged corresponding to the core insertion through hole at another radial position on the turntable, which means that when the telescopic core changing assembly is inserting or replacing the core, the cutting core assembly can simultaneously perform a new core cutting operation. This design enables the core cutting and core insertion / replacement operations to be performed simultaneously, achieving uninterrupted insertion or replacement of the cut core, reducing waiting time and idle time, and making the entire production process more compact and efficient, which not only improves production efficiency but also reduces production costs.

[0030] 5) When the controller receives the position change signal of the conductive foam to be inserted or replaced, it will control the working state of the conveying roller (such as start and stop, etc.) to ensure that after the conductive foam to be replaced or inserted into the liner on the upper film is conveyed to the bottom of the conductive foam upper pressure piece by the conveying roller, the conveying roller stops working and automatically controls the conveying roller to work. The coordinated work of the conveying roller and the pressure wheel assembly helps to achieve stable conveying of the upper film and ensure the flatness of the upper film conveying process;

[0031] 6) Through the coordinated work of the liner core conveying roller to be cut and the liner core conveying limit block, the liner core is automatically conveyed to the liner core cutting knife assembly. The liner core cutting knife assembly first cuts and continues to automatically convey the cut liner core to insert it into the corresponding liner core insertion hole at another radial position on the turntable. This design facilitates subsequent processing or assembly process. The entire process is automatically controlled without manual intervention, which greatly improves production efficiency.

[0062] The present invention provides a working method of a conductive foam automatic lining core replacement device, comprising the following steps:

[0063] The sensor assembly 3 is preferably a displacement sensor. When the position of the conductive foam to be inserted or replaced in the liner core has not been delivered to the bottom of the conductive foam upper pressure piece 4, the displacement sensor detects a signal that the position of the conductive foam to be inserted or replaced in the liner core has not been delivered to the bottom of the conductive foam upper pressure piece 4, and sends a signal to the controller that the position of the conductive foam to be inserted or replaced in the liner core has not been delivered to the bottom of the conductive foam upper pressure piece 4. The controller detects the signal, processes the signal, and controls the conveying roller drive assembly 11 to drive the conveying roller 10. The conveying roller 10 drives the pressure wheel assembly 13 to work. The pressure wheel assembly 13 corresponds to the conveying roller 10 and cooperates with each other to convey the upper film 1 from the entrance 18 of the upper film conveying device to the exit 19 of the upper film conveying device.

[0064] The sensor assembly 3 is preferably a displacement sensor. When the position of the conductive foam to be inserted or replaced in the liner core is transported to the bottom of the conductive foam upper pressing piece 4, the displacement sensor detects a signal that the position of the conductive foam to be inserted or replaced in the liner core is transported to the bottom of the conductive foam upper pressing piece 4, and sends a signal to the controller that the position of the conductive foam to be inserted or replaced in the liner core is transported to the bottom of the conductive foam upper pressing piece 4. The controller detects the signal, processes the signal, and controls the conveying roller drive assembly 11 to stop driving, and the conveying roller 10 stops working.

[0065] The sensor component 3 is preferably a displacement sensor. When the position of the conductive foam to be inserted or replaced of the liner core is transported to the bottom of the conductive foam upper pressure piece 4, and the position of the conductive foam to be inserted or replaced of the liner core stops changing, the displacement sensor detects a signal that the position of the conductive foam to be inserted or replaced of the liner core is transported to the bottom of the conductive foam upper pressure piece 4, and the position of the conductive foam to be inserted or replaced of the liner core stops changing, and sends a signal to the controller that the position of the conductive foam to be inserted or replaced of the liner core is transported to the bottom of the conductive foam upper pressure piece 4, and the position of the conductive foam to be inserted or replaced of the liner core stops changing. The controller detects the signal, processes the signal, and controls the conductive foam upper pressure driving component 5 to drive the connecting member 41 to drive the liner core insertion guide member 42 to press onto the conductive foam 2 to be inserted or replaced of the liner core;

[0066] The sensor assembly 3 is preferably a pressure sensor. When the conductive foam upper pressure piece 4 is pressed onto the conductive foam to be inserted or replaced, the pressure sensor detects a signal of the conductive foam upper pressure piece 4 pressing onto the conductive foam 2 to be inserted or replaced, and sends a signal to the controller that the conductive foam upper pressure piece 4 is pressing onto the conductive foam 2 to be inserted or replaced. The controller detects the signal, processes the signal, and controls the stepper motor 7 to drive the turntable 6 to rotate according to the preset rotation speed and rotation angle parameters of the turntable 6 and transport the inserted liner 8 to be inserted to the telescopic core replacement assembly 9.

[0067] When the liner core 8 to be inserted is delivered to the telescopic core-changing assembly 9, the magnetic switch 91 detects the signal that the liner core 8 to be inserted is delivered to the telescopic core-changing assembly 9, and controls the telescopic core-changing assembly 9 to move and extend toward the direction close to the upper plate film 1, and drives the liner core 8 to be inserted thereon to be inserted into the liner core insertion through hole 62 at a radial position on the turntable 6 and the liner core insertion guide groove in sequence until the liner core 8 to be inserted is accurately inserted into the conductive foam 2;

[0068] When the optical fiber head detects that the liner core insertion hole 62 at a radial position on the turntable 6 is set corresponding to the liner core insertion groove to be inserted, the optical fiber head 14 detects a signal that the optical fiber head detects that the liner core insertion hole 62 at a radial position on the turntable 6 is set corresponding to the liner core insertion groove to be inserted, and sends a signal to the controller that the optical fiber head 14 detects that the liner core insertion hole 62 at a radial position on the turntable 6 is set corresponding to the liner core insertion groove to be inserted. The controller detects the signal, processes the signal, and controls the liner core conveying drive assembly 21 to drive the liner core conveying roller 20 to work, conveys the liner core 8 to be cut to the liner core cutting knife assembly 24 for cutting, and continues to convey The cut liner 25 is inserted into the core insertion hole 62 at another radial position on the turntable 6 while the telescopic core changing assembly 9 is inserting the core to be inserted into the conductive foam 2; the automatic driving stepper motor 7 drives the turntable 6 to rotate, and can quickly and accurately transport the cut liner in the core insertion hole 62 at a radial position on the turntable 6 to the telescopic core changing assembly 9, and at the same time, synchronously insert a new cut liner 25 into the core insertion hole 62 at another radial position on the turntable 6, and repeat the above steps to realize the uninterrupted insertion or replacement of the cut liner, thereby ensuring the continuity of the production process and improving the efficiency of the overall production line.

[0069] The present invention provides a working method for an automatic conductive foam liner replacement device, which is easy to operate and meets the requirements of high-precision alignment and insertion of replacement liner cores, effectively avoiding problems of artificial damage and contamination of the surface of the conductive foam, improving production efficiency, reducing production costs, ensuring that the quality and effect of each insertion and replacement of the liner core are completely consistent, and improving the overall performance and stability of the product.
