In the production process of the conductive film, each layer of structure needs to be compounded, such as the upper circuit film, the isolation layer, the lower circuit film, etc. After the compounding is completed, the conductive film needs to be hot-pressed to improve the composite effect between the layers.

[0028] The keyboard conductive film that has been composited is loaded in the form of a roll. The roll is loaded through the unwinding mechanism 02, and after passing through multiple groups of material-passing strip holes 0931 in sequence, it is rolled up by the rewinding mechanism 03. When the roll passes through the material-passing strip holes 0931 corresponding to the bottom of the hot pressing mechanism 11, the X-axis driving component 05 and the Y-axis driving component 08 drive the hot pressing mechanism 11 to run to the position directly above the position that needs hot pressing, and the hot pressing process is performed on the position through the hot pressing mechanism 11. The advantages of this design are: abandoning the traditional sheet-like conductive film loading mode and improving it to a roll loading mode can greatly improve the conveying efficiency of the conductive film. On the other hand, by arranging multiple groups of hot pressing modules side by side, multiple positions on the roll can be hot pressed at the same time, which improves the efficiency of hot pressing.

[0029] The winding mechanism 03 includes a first mounting bracket 031, a first rotating motor 032, a feeding roller 033, a buffer rack 034 and a winding roller 035. The first mounting bracket 031 is fixed to the feeding end of the frame 01, the first rotating motor 032 is fixed to the first mounting bracket 031, the feeding roller 033 is rotatably mounted on the first mounting bracket 031 and one end is connected to the power output end of the first rotating motor 032, the buffer rack 034 and the winding roller 035 are fixedly arranged in sequence on one side of the winding roller 035 along the feeding direction.

[0030] The first rotary motor 032 drives the unloading roller 033 to rotate, thereby driving the coil to be transported to one side of the buffer rack 034. The buffer rack 034 buffers the coil, and the coil is reeled up by the reeling roller 035.

[0031] The winding mechanism 03 also includes a clamping assembly 036, which includes a first Z-axis cylinder 0361, a connecting bracket 0362, a mounting cross bar 0363, a sliding sleeve 0364, a locking screw 0365 and a clamping roller 0366. The first Z-axis cylinder 0361 is fixed to the first mounting bracket 031, and the connecting bracket 0362 is fixed to the power output end of the first Z-axis cylinder 0361. The first Z-axis cylinder 0361 and the connecting bracket 0362 are each provided with two groups and correspond to the two ends of the unloading roller 033 respectively. The two ends of the rod 0363 are respectively fixed on two sets of connecting brackets 0362, the sliding sleeve 0364 is sleeved on the mounting cross bar 0363 and is slidably connected to the mounting cross bar 0363, one end of the locking screw 0365 is threadedly connected to the sliding sleeve 0364 and the end thereof is in contact with the mounting cross bar 0363, the clamping roller 0366 is rotatably mounted on the sliding sleeve 0364 and corresponds to the top of the unloading roller 033, and at least two sets of the sliding sleeve 0364, the locking screw 0365 and the clamping roller 0366 are arranged on the mounting cross bar 0363.

[0032] After the locking screw 0365 is loosened, the sliding sleeve 0364 can adjust its position on the mounting cross bar 0363, so that the clamping roller 0366 is adjusted to a suitable position. When conveying the coil, the mounting cross bar 0363 is driven down by the first Z-axis cylinder 0361, so that the clamping roller 0366 is pressed on the upper surface of the coil, thereby increasing the friction between the coil and the unloading roller 033, so as to improve the stability of the unloading roller 033 when conveying the coil.

[0033] The mounting base 09 includes a mounting base 091, a support block 092, a support stand 093 and a connecting column 094. The mounting base 091 is fixed to the power output end of the Y-axis drive assembly 08 and is slidably connected to the Y-axis slide 07. The hot pressure platform 10 is fixed to the upper middle part of the mounting base 091. The support block 092 is fixed to the upper part of the mounting base 091. The support block 092 is arranged in two groups and corresponds to the two sides of the hot pressure platform 10 respectively. The lower end of the support stand 093 is fixed on the support block 092. The support stand 093 is arranged in two groups and corresponds to the left and right sides of the support block 092 respectively. The support stand 093 is provided with a material passing strip hole 0931. The two ends of the connecting column 094 are respectively fixed on the two groups of support stands 093. There are multiple groups of connecting columns 094. The hot pressing mechanism 11 is fixed to the upper end of the support stand 093.

[0034] The frame body formed by connecting the supporting frame 093 and the connecting column 094 is fixed on the installation base plate 091 through the supporting block 092, so that there is a larger installation space inside the installation seat 09 and the weight of the installation seat 09 is reduced as much as possible.

[0035] A pressure sensor 101 is fixedly provided on the upper end of the hot pressing platform 10. When the hot pressing mechanism 11 performs hot pressing on the coil, the pressure applied to the coil gradually increases. The pressure applied to the coil can be measured in real time by the pressure sensor 101. When the preset pressure is reached, the hot pressing mechanism 11 stops pressing down, thereby accurately controlling the hot pressing pressure and improving the hot pressing effect.

[0036] The hot pressing mechanism 11 includes a second mounting bracket 111, a Z-axis slide 112, a Z-axis driving assembly 113, a lifting plate 114 and a hot pressing head 115. The second mounting bracket 111 is fixed to the upper end of the mounting seat 09, the Z-axis slide 112 and the Z-axis driving assembly 113 are both fixed on the second mounting bracket 111, the lifting plate 114 is fixed to the power output end of the Z-axis driving assembly 113 and is slidably connected to the Z-axis slide 112, the hot pressing head 115 is fixed to the lower end of the lifting plate 114 and corresponds to the top of the hot pressing platform 10, and the hot pressing head 115 adopts an electromagnetic pulse hot pressing head 115.

[0037] The Z-axis driving assembly 113 drives the lifting plate 114 to descend on the Z-axis slide 112, so that the hot pressing head 115 is pressed tightly against the coil. The hot pressing head 115 adopts an electromagnetic pulse hot pressing head 115, and abandons the traditional heating rod method for heating, which can make the heating efficiency faster and the heating temperature more stable.

[0038] The hot pressing mechanism 11 also includes a first buffer component 116, which includes a first boss 1161, a second boss 1162 and a first buffer spring 1163. The first boss 1161 is fixed on the second mounting bracket 111 and corresponds to the top of the lifting plate 114. The second boss 1162 is fixed on the lifting plate 114. The upper and lower ends of the first buffer spring 1163 are respectively fixed on the first boss 1161 and the second boss 1162. The first boss 1161, the second boss 1162 and the first buffer spring 1163 are arranged in two groups and correspond to the two sides of the Z-axis driving component 113 respectively.

[0039] When the Z-axis driving assembly 113 drives the lifting plate 114 to descend, the first buffer spring 1163 is stretched, thereby playing a buffering role in the descent of the lifting plate 114 .

[0040] The hot pressing mechanism 11 further includes a diaphragm conveying assembly 117, which includes a film-laying roller 1171, a film-collecting roller 1172, a damping roller 1173, a second rotating motor 1174, an elastic telescopic frame 1175 and a limit block 1176. The film-laying roller 1171 and the film-collecting roller 1172 are rotatably mounted on the lifting stand 114 through a rotating shaft, and the film-laying roller 1171 and the film-collecting roller 1172 correspond to the hot pressing head 1171, respectively. 15, the damping rollers 1173 are rotatably mounted on the lifting plate 114, the outer circumference of the damping rollers 1173 is wrapped with elastic rings, the elastic rings are in conflict with the rotating shaft of the film-laying roller 1171, and the damping rollers 1173 are symmetrically arranged in two groups about the rotating shaft of the film-laying roller 1171. The second rotating motor 1174 is fixed on the lifting plate 114 and the power output end is connected to the rotating shaft of the film-collecting roller 1172. The elastic telescopic frame 1175 includes a fixed frame 117 51, buffer slide 11752, buffer frame 11753, third convex column 11754, fourth convex column 11755 and second buffer spring 11756, fixed frame 11751 is fixed to the lower end of lifting plate 114, buffer slide 11752 is vertically fixed on fixed frame 11751, buffer frame 11753 is slidably connected with buffer slide 11752, third convex column 11754 is fixed to the upper end of buffer frame 11753, fourth convex column 11755 and second buffer spring 11756 are provided. 55 is fixed on the fixing frame 11751 and corresponds to the lower part of the third protrusion 11754, the upper and lower ends of the second buffer spring 11756 are respectively fixed on the third protrusion 11754 and the fourth protrusion 11755, the limit block 1176 is fixed on the lower end of the buffer frame 11753, and a limit through hole 11761 is vertically provided on the limit block 1176, and the elastic telescopic frame 1175 and the limit block 1176 are each arranged in two groups and correspond to the two sides of the hot pressing head 115 respectively.

[0041] In order to prevent the hot pressing head 115 from directly contacting the coil and to protect the coil, a diaphragm can be provided between the hot pressing head 115 and the coil. The conventional diaphragm is directly pasted on the hot pressing head 115. After being used several times, the diaphragm will become dirty and need to be replaced frequently, otherwise it will affect the appearance of the conductive film. The diaphragm coil of the present design is discharged through the film discharge roller 1171 and passes through the limiting through holes 11761 on the two sets of limiting blocks 1176 in sequence, so that the diaphragm corresponds to the bottom of the hot pressing head 115, which can protect the conductive film coil during hot pressing and can be replaced according to the method described above. According to the demand, after a certain number of hot pressing, the second rotating motor 1174 drives the film collecting roller 1172 to rotate, thereby winding the diaphragm and replacing the diaphragm under the hot pressing head 115, thereby avoiding frequent manual replacement of the diaphragm and improving production efficiency. Two sets of damping rollers 1173 are arranged at the end of the rotating shaft of the film unwinding roller 1171. The elastic ring outside the damping roller 1173 hinders the rotation of the rotating shaft of the film unwinding roller 1171 through friction, so that the film unwinding roller 1171 can only rotate when the film collecting roller 1172 rotates, thereby realizing stable material unwinding.

[0042] The heat pressing mechanism 11 also includes a positioning component 118, which includes a camera 1181 and a light source component 1182. The camera 1181 is fixed on the second mounting bracket 111 with the shooting end facing downward, and the light source component 1182 is fixed on the mounting seat 09 and corresponds to the bottom of the camera 1181.

[0043] Before hot pressing the coil, the X-axis drive component 05 and the Y-axis drive component 08 are used to drive the camera 1181 to take pictures and locate the unknown part of the hot pressing, thereby improving the accuracy of the hot pressing. The light source component 1182 provides fill light for the camera 1181 when taking pictures, thereby improving the effect of the picture positioning.

[0044] The hot pressing mechanism 11 also includes a cooling component 119, which includes an air inlet connector 1191, a regulating valve 1192 and a universal tube 1193. The air inlet connector 1191 is fixed on the lifting plate 114, the regulating valve 1192 is fixed on the air inlet connector 1191 and is connected to the air inlet connector 1191, and one end of the universal tube 1193 is fixed on the regulating valve 1192, and the other end faces the hot pressing platform 10.

[0045] The air inlet connector 1191 is connected to the air supply equipment. After the hot pressing head 115 completes the hot pressing of the coil, the Z-axis drive assembly 113 drives the hot pressing head 115 to reset. At this time, the air outlet end of the universal tube 1193 is aligned with the hot pressing position and outputs cooling gas, so that the coil is cooled quickly and the production efficiency is improved. The regulating valve 1192 can adjust the air outlet volume.

[0046] The above does not limit the technical scope of the present invention in any way. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
