Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1

[0035] See also Figure 1-Figure 3 The present invention provides a technical solution: a processing technology for a flexible copper clad laminate, comprising the following steps:

[0036] Step 1: Mix the resin, curing agent, accelerator, solvent, etc. in a certain proportion to make a glue solution, and then apply the glue solution on the substrate to form a glue layer;

[0037] Step 2: Place the substrate coated with the adhesive layer in an oven for drying to evaporate the solvent and solidify the adhesive layer. Slice the dried substrate into square substrates.

[0038] Step 3: The aluminum foil is continuously fed by driving the unfolding member 41 in the hot pressing device, and the substrate is pushed to the workbench below the pressing plate 3 by the provided feeding member 43.

The feeding component 43 can automatically push the stacked substrate plates 5 to the upper surface of the machine body 1 and is located under the pressing plate 3. A lifting component 6 is provided between the feeding component 43 and the machine body 1. The substrate plates 5 are stacked in the lifting component 6. A rolled copper foil 44 located under the pressing plate 3 is provided on the upper surface of the machine body 1. The rolled copper foil 44 is tensioned as a whole. A linkage component 42 is provided between the feeding component 43 and the driving and unfolding component 41. The linkage component 42 can drive the pushing plate 431 to move and push the substrate plates 5 while allowing the front driving shaft 411 to rotate. A driving and unfolding component 41 is provided between the right side of the rolled copper foil 44 and the right end of the machine body 1 to realize the movement and adjustment of the position of the rolled copper foil 44.

[0041] The driving and unfolding member 41 includes a front drive shaft 411 and a rear drive shaft 414 horizontally located at the front and rear of the body 1, respectively. A working motor 412 is provided at the right end of the front drive shaft 411. The working motor 412 can drive the front drive shaft 411 to rotate. A winding roller 416 and an unwinding roller 415 are respectively provided on the front drive shaft 411 and the rear drive shaft 414. The two ends of the rolled copper foil 44 are respectively wound around the unwinding roller 415 and the winding roller 416. As the unwinding roller 415 and the winding roller 416 rotate, the rolled copper foil 44 can be driven to move, thereby changing the position of the rolled copper foil 44 covering the substrate plate 5.

[0042] The feeding member 43 includes a push plate 431 horizontally located on the left side of the substrate plate 5. The push plate 431 moves rightward to push the substrate plate 5 to the right and send it under the pressing plate 3. A fixing column is vertically provided on the upper end of the push plate 431.

[0043] The linkage member 42 includes a worm 421 sleeved on the front drive shaft 411, and the worm 421 can rotate synchronously with the front drive shaft 411. A worm wheel 422 is meshed with the front side of the worm 421, and a mounting shaft 423 is vertically arranged in the worm wheel 422. The worm wheel 422 and the mounting shaft 423 rotate. A connecting plate 425 is sleeved on the upper end of the mounting shaft 423, and the connecting plate 425 rotates with the mounting shaft 423. The other end of the connecting plate 425 is rotatably connected to the rotating plate 426. The other end of the rotating plate 426 is rotatably sleeved on the fixed column. The rotating plate 426 can rotate around the fixed column, and at the same time drive the fixed column and the push plate 431 to move.

[0044] In this embodiment, preferably, a support plate 417 is provided between the front drive shaft 411 and the rear drive shaft 414 and the body 1. The support plate 417 does not affect the rotation of the front drive shaft 411 and the rear drive shaft 414, while supporting the two. The right ends of the front drive shaft 411 and the rear drive shaft 414 are both provided with pulleys 413, and a connecting belt is provided between the two pulleys 413. By combining the connecting belt and the pulley 413, the front drive shaft 411 and the rear drive shaft 414 can be rotated simultaneously.

[0045] In summary, when in use, the working motor 412 works, driving the front drive shaft 411 to rotate, and the rear drive shaft 414 rotates under the action of the pulley 413 and the connecting belt, driving the unwinding roller 415 and the winding roller 416 to rotate synchronously. The synchronous rotation of the two allows the wound copper foil 44 to move forward, allowing the new unused copper foil surface to be located below the pressing plate 3. While the front drive shaft 411 rotates, it drives the worm 421 to rotate, and the worm gear 422 and the mounting shaft 423 engaged therewith rotate, and the mounting shaft 423 rotates. The connecting plate 425 is driven to rotate, and the rotating plate 426 is located above the connecting plate 425, and the two are connected in rotation. Therefore, the rotating plate 426 rotates around the connection as the connecting plate 425 rotates, and the rotating plate 426 rotates the other end around the fixed column, while the rotation drives the push plate 431 to move rightward along the guide plate 433. The push plate 431 pushes the substrate plate 5 on the lifting plate 61 to the right until it is located under the pressing plate 3 and the rolled copper foil 44. As the entire hot press works, the pressing plate The protruding cutting blades on the 3rd periphery cut a rectangular part of the surface of the rolled copper foil 44 and press the cut part onto the substrate plate 5. After the pressing process is completed, the pressing plate 3 moves upward. Without the restriction of the pressing plate 3, the rolled copper foil 44 moves upward and rebounds, and the working motor 412 works again. The rolled copper foil 44 is driven forward by the front driving shaft 411 to roll up the part with the cut notch. At the same time, the pushing plate 431 is driven to move to the right as the front driving shaft 411 rotates, and the pushing plate 431 moves the top substrate plate 5 to the right. The new substrate plate 5 pushes the substrate plate 5 with the processed surface on the upper surface of the machine body 1 to the right. After the new substrate plate 5 is in the processing position, the processed substrate plate 5 is located to the right in the positioning long plate 71 and can be removed. While the new substrate plate 5 is in the processing position, the rectangular notch of the rolled copper foil 44 is rolled up, and the surface of the new copper foil is located above the new substrate plate 5, realizing the next pressing process. The whole process is repeated to achieve stable processing of the substrate plate 5 and improve processing efficiency.

The tensioning member 45 includes two driving cylinders 452 respectively fixed vertically on the inner side surfaces of the support plates 417, and piston rods are provided inside the two driving cylinders 452. A tensioning roller 451 in contact with the upper surface of the rolled copper foil 44 is horizontally provided between the two piston rods. The surface of the tensioning roller 451 is smooth, which does not affect the movement of the rolled copper foil 44, and can be slightly pressed downward to tension it, so that the surface of the rolled copper foil 44 is flat and smooth without wrinkles. The free end of the piston rod passes through the tensioning roller 451, and a connecting bolt is provided between the two to achieve a detachable connection between the two.

[0049] In this embodiment, preferably, a tailstock 432 is provided at the left end of the pushing plate 431, and the tailstock 432 is U-shaped. A guide plate 433 is provided on the front and rear surfaces of the lifting member 6. The left end of the guide plate 433 extends out of the lifting member 6 and is exposed to the outside. The left end of the guide plate 433 passes through the tailstock 432 and is exposed to the outside. The guide plate 433 cooperates with the tailstock 432, which neither affects the left and right movement of the pushing plate 431 nor guides the movement direction.

[0050] In summary, when in use, the working motor 412 drives the front drive shaft 411 to rotate, and a pulley 413 and a connecting belt are set between the rear drive shaft 414 and the front drive shaft 411 to drive the rear drive shaft 414 to rotate, so that the front winding roller 416 gradually rotates and winds, and the unwinding roller 415 rotates and opens, so that the position of the wound copper foil 44 moves, so that the new unused wound copper foil 44 is located below the pressing plate 3. During the movement of the wound copper foil 44, the tensioning roller 451 can always assist in tensioning the wound copper foil 44 to a certain extent, so that the wound copper foil 44 is flat as a whole without wrinkles, thereby increasing the stability and safety of the wound copper foil 44 during the pressing process.

[0051] Example 3

[0052] Reference Figure 6-Figure 8 , which is the third embodiment of the present invention, and the difference between this embodiment and the above two embodiments is.

[0053] In this embodiment, preferably, the lifting member 6 includes two side positioning plates 62 fixed to the left side of the machine body 1, and a lifting plate 61 is horizontally arranged inside the two side positioning plates 62. The substrate plate 5 can be placed on the upper surface of the lifting plate 61. A bidirectional screw rod 65 is horizontally arranged below the side positioning plate 62. A stabilizing plate 63 is arranged between the middle position of the bidirectional screw rod 65 and the machine body 1. The stabilizing plate 63 can support and stabilize the bidirectional screw rod 65. A driving motor 64 is arranged at the front end of the bidirectional screw rod 65. A driving motor 64 is arranged between the driving motor 64 and the side positioning plate 62. The frame increases the installation strength of the drive motor 64, and the drive motor 64 can drive the bidirectional screw rod 65 to rotate. Two nut blocks 66 are screwed on the bidirectional screw rod 65, which are respectively located in the front and rear of the stabilizing plate 63. A rotating rod 67 is rotatably provided between the upper surface of the nut block 66 and the lower surface of the lifting plate 61. A sliding groove is provided on the inner surface of the side positioning plate 62 along its height direction, and a slider extending into the sliding groove is provided on the surface of the lifting plate 61. The slider and the sliding groove slide together to limit the lifting plate 61 so that it will not rotate while moving up and down.

[0054] In this embodiment, preferably, a guide member 7 is provided on the upper surface of the body 1 and is located on the right side of the rolled copper foil 44. The guide member 7 can guide the substrate plate 5 that is unloaded outward after the cladding process. The guide member 7 includes two symmetrically distributed positioning long plates 71, and the distance between the two positioning long plates 71 is adjustable. Fixed sleeves 72 are provided on the front and rear surfaces of the body 1, and a fixed long rod 73 that passes through the fixed sleeve 72 is vertically provided on the outer surface of the positioning long plate 71. A limiting rod is screwed together between the fixed sleeve 72 and the fixed long rod 73, and the limiting rod is screwed and installed on the lower surface of the fixed sleeve 72, and the upper end of the limiting rod is in contact with the surface of the fixed long rod 73, thereby increasing the friction resistance between the fixed long rod 73 and the fixed sleeve 72, thereby limiting and fixing the position of the positioning long plate 71.

[0055] In summary, when in use, the driving motor 64 works, driving the bidirectional screw rod 65 to rotate, and the two nut blocks 66 thereon rotate accordingly and move relative to each other, driving the rotating rod 67 between the nut block 66 and the lifting plate 61 to rotate, and the angle of the rotating rod 67 to the vertical direction is adjusted. The angle of the rotating rod 67 changes, which can drive the lifting plate 61 to move upward, and the slider moves along the slide groove, so that the lifting plate 61 moves up and down without sideways rotation. As the lifting plate 61 moves, it drives the substrate plate 5 placed thereon to move upward, and the new substrate plate 5 is located on the right side of the pushing plate 431. As the subsequent pushing plate 431 pushes the substrate plate 5 to move and be sent to the bottom of the pressing plate 3, the stacked substrate plates 5 are continuously moved upward and fed, and when the new substrate plate 5 moves to the bottom of the pressing plate 3, the processed substrate plate 5 is pushed to the right by the new substrate plate 5 and positioned in the positioning long plate 71, and the substrate plate 5 located in the positioning long plate 71 can be removed.

[0057] This embodiment is obtained by combining Example 1, Example 2 and Example 3.

[0058] When in use, the lifting component 6 adjusts the height of the substrate plate 5 of the lifting plate 61, and uses the driving unfolding component 41 to drive the front drive shaft 411 and the rear drive shaft 414 to rotate, so that the surface of the rolled copper foil 44 between the two is moved and unfolded. While the front drive shaft 411 rotates, the linkage component 44 is used to drive the pushing plate 431 to move, and the top substrate plate 5 is pushed to the bottom of the rolled copper foil 44. As the hot press works, the rolled copper foil 44 and the substrate plate 5 are pressed and processed, and the whole process continuously realizes the new substrate plate 5 and the rolled copper foil 44 pressing and processing, thereby improving the processing stability and processing efficiency of the two.
