Description

Technical Field

[0001] The present invention relates to the technical field of conductive foam production, and in particular to a production system and process for multi-structure scoop-shaped hollow conductive foam. Background Art

[0002] Conductive foam refers to flame-retardant sponge wrapped with conductive cloth. It can be easily glued to devices that require pressure shielding and has been widely used in electromagnetic shielding of various electronic devices.

[0003] Ladle-shaped hollow conductive foam refers to a conductive foam that is wrapped with conductive cloth to form a cavity with a cylindrical surface. In the production process of existing ladle-shaped hollow conductive foam, manual labor or flat knife processing is usually used to cut and compound the ladle-shaped hollow conductive foam. In order to wrap the conductive cloth to form a cavity with a cylindrical surface, a tube core with a cylindrical surface is usually manually strung in to shape it, so that the conductive cloth is wrapped on the tube core. This production method has low working efficiency and is prone to flattening and deforming of the hollow wrapped surface, affecting the product yield. Summary of the Invention

[0004] The purpose of the present invention is to provide a production system and process for multi-structure scoop-shaped hollow conductive foam, which can save product assembly time, improve product production efficiency, and improve product yield.

[0005] In order to solve the above technical problems, the present invention adopts the following solutions:

[0006] In the first aspect, a production system for a multi-structure gourd-shaped hollow conductive foam adopts a circular knife die-cutting machine, wherein the multi-structure gourd-shaped hollow conductive foam includes a tube core having a cylindrical surface and a plane surface set back to each other, and the tube core is wrapped with a conductive cloth, and the conductive cloth includes a contact portion for contacting the tube core and a plane portion located outside the tube core, the tube core is arranged on the top surface of the plane portion, and a release film is provided on the bottom surface of the plane portion. The release film and the conductive cloth are bonded by conductive glue, and a tape is provided on the side of the contact portion facing the tube core. The contact portion includes a bonding area provided on the outer edge of the conductive cloth and bonded to the plane portion after folding. The circular knife die-cutting machine is provided with a plurality of contact portions for contacting the release film from the front to the back along the processing direction. The first die-cutting group performs preliminary die-cutting on the molded film; the conductive fabric laminating roller laminates the conductive fabric onto the top surface of the pre-die-cut release film; the second die-cutting group performs preliminary die-cutting on the adhesive tape and laminates the pre-die-cut adhesive tape onto the top surface of the conductive fabric; the third die-cutting group performs final die-cutting on the conductive fabric, with the adhesive tape and release film laminated on the upper and lower surfaces respectively; the fourth die-cutting group performs die-cutting on the skeleton layer that provides auxiliary support for the wrapping of the conductive fabric and laminates the die-cut skeleton layer onto the bottom surface of the conductive fabric; the wrapping jig wraps the conductive fabric around the tube core; and the fifth die-cutting group performs segmented die-cutting on the tube core within the wrapped conductive fabric and separates the skeleton layer from the conductive fabric. The release film is PET release film. Its function is to realize the fully automatic cutting and compounding of each layer structure of the multi-structure gourd-shaped hollow conductive foam through the sequential arrangement of the first die-cutting group, the conductive cloth composite roller, the second die-cutting group, the third die-cutting group, and the fourth die-cutting group, thereby effectively improving the composite molding production efficiency of the multi-structure gourd-shaped hollow conductive foam; through the sequential arrangement of the wrapping jig and the fifth die-cutting group after the fourth die-cutting group, the automatic core threading and wrapping of the multi-structure gourd-shaped hollow conductive foam is realized, thereby effectively improving the wrapping efficiency of the multi-structure gourd-shaped hollow conductive foam, and can effectively avoid the flattening and deformity caused by manual core threading and wrapping, and can effectively improve the yield rate.

[0007] Furthermore, the first die-cutting group includes a first die-cutting circular knife and a second die-cutting circular knife in sequence along the forward direction of the release film. The first die-cutting circular knife is provided with a first positioning mark blade group and a first axial blade group for die-cutting the head end of the release film arranged in the plane portion and perpendicular to the forward direction of the release film. The second die-cutting circular knife is provided with a second positioning mark blade group and a second circumferential blade group for die-cutting the two sides of the release film parallel to the forward direction of the release film. A part of the blades in the second circumferential blade group are connected to the two sides of the head end of the release film, and the other part of the blades are located on both sides of the bonding area. Its function is that, through the setting of the first axial blade group, it can die-cut the head end of the release film for being set in the planar part on the original strip-shaped release film material, which is perpendicular to the forward direction of the release film. Then, through the setting of the second circumferential blade group and the positioning function of the first positioning mark blade group and the second positioning mark blade group, the two sides of the release film connected to the head end of each release film in the planar part are die-cut, so that only the end of the release film on the planar part is connected to the release film material, and at the same time, the two sides of the release film for covering the bonding area are formed.

[0008] Furthermore, the second die-cutting assembly includes a third circular die-cutting blade, which is equipped with a third positioning marking blade assembly and a third circumferential blade assembly for cutting the tape on two sides parallel to the tape's forward direction. The third circumferential blade assembly is used to die-cut two sides of the original tape strip, which are then bonded to the contact portion, crossing the fold line of the conductive fabric during wrapping.

[0009] Furthermore, the third circumferential blade assembly is formed as two parallel straight lines in an expanded view of the third circular die-cutting blade. A dashed crease cutter is provided on the third circular die-cutting blade, parallel to the two straight lines of the third circumferential blade assembly. This function is to die-cut a dashed crease along the fold line of the conductive fabric when the tape is wrapped, as it straddles the fold line. Furthermore, the dashed crease acts as a buffer zone for thermal expansion of the tape during use of the multi-structured scoop-shaped hollow conductive foam, effectively extending the adhesive life of the tape.

[0010] Furthermore, the third die-cutting group includes a fourth die-cutting circular knife, which is provided with a fourth positioning mark blade group, a first conductive cloth die-cutting blade group for die-cutting the conductive cloth on the area on the outer contour of the conductive cloth that overlaps with the release film, a second conductive cloth die-cutting blade group for die-cutting the conductive cloth on the area on the outer contour of the conductive cloth that does not overlap with the release film, and a third conductive cloth die-cutting blade group for punching holes in the contact part. Its function is that, through the setting of the first conductive cloth die-cutting blade group, the conductive cloth on the area on the outer contour of the conductive cloth that overlaps with the release film and the tape on the top surface of the contact part can be die-cut without damaging the release film in this area, so that a part of the release film is left outside the outer contour area of ​​the conductive cloth to facilitate the exposed end of the release film to be peeled off; through the setting of the second conductive cloth die-cutting blade group, the conductive cloth on the area on the outer contour of the conductive cloth that does not overlap with the release film and the tape on the top surface of the contact part can be die-cut, so that the outer contour of the conductive cloth is completely formed, and at the same time, the end of the release film on the bottom surface of the contact part is cut off, so that the tape and the release film on the contact part are separately formed and composited on the conductive cloth; through the setting of the third conductive cloth die-cutting blade group, a through hole that passes through the upper and lower surfaces of the contact part can be die-cut in the conductive cloth.

[0011] Furthermore, the die-cutting depth of the third conductive cloth die-cutting blade group on the conductive cloth is greater than the die-cutting depth of the second conductive cloth die-cutting blade group on the conductive cloth, and the die-cutting depth of the second conductive cloth die-cutting blade group on the conductive cloth is greater than the die-cutting depth of the first conductive cloth die-cutting blade group on the conductive cloth. This is because, since the first conductive cloth die-cutting blade group needs to cut the outer contour of the conductive cloth without damaging the release film, and the second conductive cloth die-cutting blade group needs to cut the outer contour of the conductive cloth and the end of the release film at the contact portion, the die-cutting depth of the second conductive cloth die-cutting blade group on the conductive cloth is greater than the die-cutting depth of the first conductive cloth die-cutting blade group on the conductive cloth. Moreover, since the third conductive cloth die-cutting blade group needs to completely penetrate the conductive cloth, the die-cutting depth of the third conductive cloth die-cutting blade group on the conductive cloth is greater than the die-cutting depth of the second conductive cloth die-cutting blade group on the conductive cloth.

[0012] Furthermore, the third conductive fabric die-cutting blade assembly is in the form of strip-shaped holes evenly spaced along the circumference of the fourth circular die-cutting blade. The fourth circular die-cutting blade is provided with crease-pressing blades arranged in the form of dotted lines along the circumference of the fourth circular die-cutting blade. Each blade segment of the crease-pressing blade is located on either side of each individual strip-shaped hole. There are two crease-pressing blades: one located at the fold line on the tape, which is located at the intersection of the contact portion with the flat surface of the tube core and the contact portion with the side surface of the tube core, and the other located at the edge of the bonding area. The crease-pressing blades are configured to create two indentations in the conductive fabric, facilitating the subsequent folding and wrapping of the conductive fabric.

[0013] Furthermore, the fourth die-cutting group includes a fifth circular die-cutting knife, which is provided with a fifth positioning mark blade group and a fifth circumferential blade group for die-cutting the side of the skeleton layer parallel to the forward direction of the skeleton layer. Its function is that, through the provision of the fifth axial blade group, the original strip-shaped skeleton layer can be die-cut into multiple parallel thin strips of skeleton layers, the skeleton layer located on the plane portion is in the form of a wider single thin strip, and the skeleton layer located on the contact portion is in the form of multiple narrow thin strips, with a gap left between the skeleton layer located on the plane portion and the skeleton layer located on the contact portion. Due to the design of the skeleton layer located on the contact portion, when the contact portion is folded into a cylindrical surface during the wrapping process, the narrow thin strips of skeleton layers can be separated from each other, avoiding resistance to the folding of the cylindrical surface and deformation of the cylindrical surface.

[0014] Furthermore, the wrapping jig is provided with a shaping groove with a cylindrical bottom surface along the moving direction of the conductive cloth, and above the shaping groove, a first folding plate for folding the bonding area onto the plane of the tube core and a second folding plate for folding the flat part onto the folded bonding area are provided in sequence along the moving direction of the conductive cloth. Its function is that, through the setting of the shaping groove, the cylindrical surface on the tube core can be matched with the cylindrical surface on the shaping groove, so that the conductive part located between the tube core and the shaping groove forms a cylindrical surface shape; through the setting of the first folding plate, the bonding area can be pressed on the plane of the tube core so that the bonding part that advances to the first folding plate later is folded and pressed on the plane of the tube core as the bonding part that has passed the first folding plate is pressed on the plane of the tube core; through the setting of the second folding plate, the flat part can be pressed on the folded bonding area so that the flat part that advances to the second folding plate later is folded and pressed on the folded bonding area as the flat part that has passed the second folding plate is stuck on the folded bonding area. The surface of the bonding area in contact with the flat part has been peeled off the release film located in the bonding area before being transported to the wrapping jig to expose the conductive glue there, so that the folded flat part is bonded to the folded bonding area.

[0015] Furthermore, the fifth die-cutting assembly includes a sixth circular die-cutting blade, which is equipped with a sixth axial blade assembly for die-cutting the tube cores located outside the front and rear ends of the conductive cloth. This sixth axial blade assembly is used to die-cut the tube cores located outside the front and rear ends of the conductive cloth, thereby separating different conductive cloths with interleaved tube cores from each other for easier transportation and individual use.

[0016] In a second aspect, a production process for a multi-structure scoop-shaped hollow conductive foam is applied to the above-mentioned production system for the multi-structure scoop-shaped hollow conductive foam, comprising the following steps:

[0017] Step S1, performing preliminary die-cutting on the release film through a first die-cutting group;

[0018] Step S2: Laminating the conductive fabric on the top surface of the release film through a conductive fabric laminating roller;

[0019] Step S3: die-cutting the tape through the second die-cutting group and laminating it on the top surface of the conductive cloth;

[0020] Step S4: The conductive cloth with the adhesive tape and release film attached to the upper and lower surfaces respectively is subjected to final die-cutting by the third die-cutting group;

[0021] Step S5: die-cutting the skeleton layer through the fourth die-cutting group and laminating it on the bottom surface of the conductive cloth;

[0022] Step S6: Wrap the conductive cloth inside the tube core using a wrapping jig;

[0023] Step S7: Separate the skeleton layer from the conductive cloth through the fifth die-cutting group and die-cut the tube core through the fifth die-cutting group.

[0024] Furthermore, in step S3, the adhesive tape is die-cut and a dotted fold line is die-cut on the adhesive tape.

[0025] Furthermore, in step S5 , the skeleton layer at the contact portion is die-cut into a plurality of parallel thin strips along the extension direction of the skeleton layer.

[0026] The present invention has the beneficial effects:

[0027] 1. Through the sequential arrangement of the first die-cutting group, the conductive cloth laminating roller, the second die-cutting group, the third die-cutting group, and the fourth die-cutting group, the fully automatic cutting and laminating of each layer structure of the multi-structure scoop-shaped hollow conductive foam is realized, effectively improving the composite molding production efficiency of the multi-structure scoop-shaped hollow conductive foam;

[0028] 2. By setting up the wrapping jig after the fourth die-cutting group and the fifth die-cutting group in sequence, the automatic core-threading and wrapping of the multi-structure scoop-shaped hollow conductive foam is realized, which effectively improves the wrapping efficiency of the multi-structure scoop-shaped hollow conductive foam, and can effectively avoid the flattening and deformity caused by manual core-threading and wrapping, and can effectively improve the yield rate.

The material strip passing through the second die-cutting circular knife 502 is provided with the anti-adhesion film 19, the conductive adhesive 12, the release film 3 and the first transition protective film 13 in order from top to bottom.

[0060] Specifically, a conductive cloth laminating roller 6 for laminating the conductive cloth 2 on the top surface of the release film 3 is provided between the first die-cutting group 5 and the second die-cutting group 7 , and a double-sided tape 17 is provided on the top surface of the conductive cloth 2 passing through the conductive cloth laminating roller 6 .

[0065] Specifically, the third circumferential blade assembly 7012 appears as two parallel straight lines in the expanded view of the third die-cutting circular blade 701. A dashed line crease cutter 7013 is provided on the third die-cutting circular blade 7011, parallel to the two straight lines of the third circumferential blade assembly 7012. This crease cutter 7013 functions to create a dashed crease along the fold line of the conductive fabric 2 when wrapped, as the adhesive tape 4 straddles the fold line during wrapping. Furthermore, this crease serves as a buffer zone for thermal expansion of the adhesive tape 4 during use of the multi-structured scoop-shaped hollow conductive foam, effectively extending the adhesive life of the adhesive tape 4.

[0066] Specifically, such as Figure 14 、 Figure 16 、 Figure 17 、 Figure 18 As shown, the third die-cutting group 8 includes a fourth die-cutting circular knife 801, on which the fourth positioning mark blade group 8011 is provided, a first conductive cloth die-cutting blade group 8012 for die-cutting the conductive cloth 2 on the area where the outer contour of the conductive cloth 2 overlaps with the release film 3, a second conductive cloth die-cutting blade group 8013 for die-cutting the conductive cloth 2 on the area where the outer contour of the conductive cloth 2 does not overlap with the release film 3, and a third conductive cloth die-cutting blade group 8014 for punching holes in the contact part 201.

The third transition protective film 15 plays an auxiliary supporting role during the process of the fourth die-cutting circular knife 801.

[0068] Its function is that, through the setting of the first conductive cloth die-cutting blade group 8012, the conductive cloth 2 located in the area where the outer contour of the conductive cloth 2 overlaps with the release film 3 and the tape 4 located on the top surface of the contact part 201 can be die-cut without damaging the release film 3 in the area, so that a part of the release film 3 is left outside the outer contour area of ​​the conductive cloth 2 for facilitating the removal of the release film 3. The exposed end of the release film 3; through the setting of the second conductive cloth die-cutting blade group 8013, the conductive cloth 2 located in the area where the outer contour of the conductive cloth 2 does not overlap with the release film 3 and the tape 4 located on the top surface of the contact part 201 can be die-cut, so that the outer contour of the conductive cloth 2 is completely formed, and at the same time, the end of the release film 3 located on the bottom surface of the contact part 201 is cut off, so that the tape 4 and the release film 3 on the contact part 201 are separately formed and composited on the conductive cloth 2; through the setting of the third conductive cloth die-cutting blade group 8014, a through hole can be die-cut in the conductive cloth 2 that passes through the upper and lower surfaces of the contact part 201.

[0069] Specifically, the die-cutting depth of the third conductive cloth die-cutting blade group 8014 on the conductive cloth 2 is greater than the die-cutting depth of the second conductive cloth die-cutting blade group 8013 on the conductive cloth 2, and the die-cutting depth of the second conductive cloth die-cutting blade group 8013 on the conductive cloth 2 is greater than the die-cutting depth of the first conductive cloth die-cutting blade group 8012 on the conductive cloth 2.

[0071] Its function is that, since the first conductive cloth die-cutting blade group 8012 needs to cut the outer contour of the conductive cloth 2 but does not damage the release film 3, and the second conductive cloth die-cutting blade group 8013 needs to cut the outer contour of the conductive cloth 2 and the end of the release film 3 located at the contact portion 201, the die-cutting depth of the second conductive cloth die-cutting blade group 8013 on the conductive cloth 2 is greater than the die-cutting depth of the first conductive cloth die-cutting blade group 8012 on the conductive cloth 2, and since the third conductive cloth die-cutting blade group 8014 needs to completely penetrate the conductive cloth 2 for punching, the die-cutting depth of the third conductive cloth die-cutting blade group 8014 on the conductive cloth 2 is greater than the die-cutting depth of the second conductive cloth die-cutting blade group 8013 on the conductive cloth 2.

Each blade segment of the crease-pressing blade 8015 is located on either side of each individual strip-shaped hole. There are two crease-pressing blades 8015: one located at the fold line on the tape 4, at the junction of the contact portion 201 that contacts the die 1 flat surface and the contact portion 201 that contacts the die 1 sideways. The other is located at the edge of the bonding area 2011. The crease-pressing blades create two indentations in the conductive fabric 2, facilitating subsequent folding and wrapping of the conductive fabric 2.

A skeleton layer 18 steering roller is provided above the fifth die-cutting circular knife 901. The skeleton layer 18 steering roller turns the skeleton layer 18 180 degrees and laminates it onto the bottom surface of the release film 3. The material strip above the fourth transition protective film composite roller 903 is provided with adhesive tape 4, double-sided tape 17, conductive cloth 2, conductive adhesive 12, release film 3, skeleton layer 18, and fourth transition protective film 16 from top to bottom. A fourth transition protective film peeling roller 904 is provided behind the fourth transition protective film composite roller 903 for peeling off the fourth transition protective film 16 and the release film 3 located in the bonding area 2011. The material strip after passing through the fourth transition protective film composite roller 903 is shown in FIG. Figure 5 shown.

A gap is left between the skeleton layer 18 located at the plane part 202 and the skeleton layer 18 located at the contact part 201. Due to the design of the skeleton layer 18 located at the contact part 201, when the contact part 201 is folded into a cylindrical surface during the wrapping process, the narrower thin strip skeleton layers 18 can be separated from each other to avoid resistance to the folding of the cylindrical surface and deformation of the cylindrical surface.

[0076] Specifically, such as Figure 6 As shown, the wrapping jig 10 is provided with a shaping groove 1001 with a cylindrical bottom surface along the traveling direction of the conductive cloth 2.
