Description

Technical Field

[0001] The utility model belongs to the technical field of copper clad laminate production, and particularly relates to a heating device for copper clad laminates. Background Technique

[0002] Copper clad laminate is the abbreviation of copper clad laminate. It is a plate-like material made by impregnating electronic glass fiber cloth or other reinforcing materials with resin, and covering one or both sides with copper foil and then heating and pressing. Heating and pressing are usually completed together. Various printed circuit boards with different forms and functions are processed, etched, drilled, and copper-plated on the copper clad laminate selectively to make different printed circuits. The performance, quality, processability, manufacturing level, manufacturing cost, and long-term reliability and stability of printed circuit boards depend to a large extent on the copper clad laminate.

[0003] When the commonly used copper clad laminate heating and pressing equipment is working, after the copper clad laminate is conveyed to the corresponding position, a hot pressing head is used for heating and pressing. When this processing device is heating and pressing, the copper clad laminate needs to be stationary. Therefore, during hot pressing, the copper clad laminate needs to stop being conveyed, which affects the efficiency of the entire hot pressing process of the copper clad laminate, and further affects the overall production efficiency of the copper clad laminate. Content of the Utility Model

[0004] The purpose of the utility model is to provide a heating device for copper clad laminates. Its heating component heats and presses the copper clad laminate, and this process does not require stopping the conveyance of the copper clad laminate, thereby improving the production efficiency of the copper clad laminate to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A heating device for copper clad laminates, including a frame and a plate chain conveyor. The plate chain conveyor is installed at the bottom of the frame. Equally spaced copper clad laminate molds are fixedly installed on the plate chain conveyor. The top end of the frame is slidably connected with an installation component. A heating component is arranged at the bottom end of the installation component. A driving component for driving the installation component is arranged on one side of the top end of the frame. The driving component is meshed with the installation component. A buffer component is arranged on the other side of the top end of the frame. One end of the buffer component is fixedly connected with one end of the installation component.

[0006] Further, the installation component includes a top plate. Sliding sleeves are fixedly connected to the four corners of the top plate. The sliding sleeves are slidably connected with the cross beam at the top end of the frame. A rack is fixedly connected to the middle of one end of the top plate.

[0007] Further, there are two heating components at the bottom end of the top plate. The two heating components are symmetrically arranged. The distance between the two heating components is the same as the distance between adjacent two copper clad laminate molds.

[0008] Furthermore, the heating component includes an electric telescopic rod fixedly connected to the bottom end of the top plate, and an electric heating plate is fixedly connected to the bottom end of the electric telescopic rod.

[0009] Furthermore, the driving component includes a U-shaped frame. Connecting frames are fixedly connected to both sides of the U-shaped frame. The two connecting frames are respectively fixedly connected to both sides of the top end of the frame. A gear meshing with the rack is rotatably connected inside the U-shaped frame through a rotating shaft. A toothless portion is provided on the side wall of the gear. A reduction motor is fixedly connected to one side of the U-shaped frame, and the output shaft of the reduction motor is fixedly connected to one end of the rotating shaft.

[0010] Furthermore, the buffering component includes a cylinder fixedly connected to one end of the top end of the frame. A head is slidably connected inside the cylinder. One end of the head is fixedly connected to a connecting rod, and one end of the connecting rod is fixedly connected to one end of the top plate. The other end of the head is fixedly connected to a tension spring, and one end of the tension spring is fixedly connected to one end of the inner wall of the cylinder.

[0011] Furthermore, a through hole is provided on the side wall of the cylinder, the through hole penetrates the side wall of the cylinder, and a notch is provided at one end of the cylinder and is equidistantly distributed around the axis of the cylinder.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the copper clad laminate is conveyed to the lower part of the heating component, the driving component drives the mounting component to move forward synchronously with the copper clad laminate, and the heating component heats and presses the copper clad laminate. During this process, it is not necessary to stop conveying the copper clad laminate, thereby improving the production efficiency of the copper clad laminate; and after the hot pressing is completed, the buffering component also plays a buffering role, avoiding too fast end speed when the mounting component returns, resulting in too large impact force and improving the stability of the device.

[0019] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text only describes one or several specific implementation modes of the present utility model, and does not strictly limit the scope of protection specifically requested by the present utility model.

[0020] As Figure 1 and 2 shown, a copper clad laminate heating device includes a frame 1 and a plate chain conveyor 2. The plate chain conveyor 2 is installed at the bottom of the frame 1. Equally spaced copper clad laminate molds 3 are fixedly installed on the plate chain conveyor 2. An installation component 4 is slidably connected to the top end of the frame 1. A heating component 5 is arranged at the bottom end of the installation component 4. A driving component 6 for driving the installation component 4 is arranged on one side of the top end of the frame 1. The driving component 6 is meshed and connected with the installation component 4. A buffer component 7 is arranged on the other side of the top end of the frame 1. One end of the buffer component 7 is fixedly connected with one end of the installation component 4.

[0021] According to the above structure, during use, the copper clad laminate base layer and surface layer are sequentially placed inside a number of copper clad laminate molds 3. The copper clad laminate is conveyed forward by the plate chain conveyor 2. When the copper clad laminate is conveyed below the heating component 5, the driving component 6 drives the installation component 4 to move forward synchronously with the copper clad laminate. The heating component 5 heats and presses the copper clad laminate, so that the surface layer and the base layer are bonded together to complete the production of the copper clad laminate. After hot pressing, the installation component 4 returns to the initial position under the drive of the buffer component 7 for the next round of hot pressing. When returning, the buffer component 7 also plays a buffering role to prevent the end speed of the installation component 4 from being too fast when returning, resulting in too large an impact force.

[0022] As Figure 1 and 3As shown, the installation component 4 includes a top plate 41. Sliding sleeves 42 are fixedly connected to the four corners of the top plate 41. The sliding sleeves 42 are slidably connected to the cross beams at the top end of the frame 1. In the middle of one end of the top plate 41, a rack 43 is fixedly connected. The driving component 6 includes a U-shaped frame 61. Connecting frames 62 are fixedly connected to both sides of the U-shaped frame 61. The two connecting frames 62 are respectively fixedly connected to both sides of the top end of the frame 1. Inside the U-shaped frame 61, a gear 63 meshing with the rack 43 is rotatably connected through a rotating shaft. A toothless part 64 is arranged on the side wall of the gear 63. On one side of the U-shaped frame 61, a reduction motor 65 is fixedly connected. The output shaft of the reduction motor 65 is fixedly connected to one end of the rotating shaft.

[0023] According to the above structure, during use, the reduction motor 65 drives the gear 63 to rotate. The gear 63 is meshed with the rack 43, thereby driving the top plate 41 to move. The top plate 41 is slidably connected to the frame 1 through the sliding sleeves 42. When the toothless part 64 on the gear 63 rotates to contact the bottom end of the rack 43, the entire installation component 4 can move back under the drive of the buffer component 7.

[0024] As Figure 3 shown, there are two heating components 5 at the bottom end of the top plate 41. The two heating components 5 are symmetrically arranged. The distance between the two heating components 5 is the same as the distance between two adjacent copper clad laminate molds 3. The heating component 5 includes an electric telescopic rod 51 fixedly connected to the bottom end of the top plate 41. At the bottom end of the electric telescopic rod 51, an electric heating plate 52 is fixedly connected.

[0025] According to the above structure, the setting of the two heating components 5 can heat and hot press two copper clad laminates simultaneously and provide corresponding time for the overall movement back of the installation component 4. During heating, the electric telescopic rod 51 extends, and the electric heating plate 52 contacts the surface layer of the copper clad laminate, heating the surface layer and hot pressing the surface layer onto the base layer. After hot pressing is completed, the electric telescopic rod 51 contracts, and the electric heating plate 52 rises.

[0026] As Figure 3 and 4 shown, the buffer component 7 includes a cylinder 71 fixedly connected to one end of the top end of the frame 1. A head 75 is slidably arranged inside the cylinder 71. One end of the head 75 is fixedly connected to a connecting rod 74. One end of the connecting rod 74 is fixedly connected to one end of the top plate 41. The other end of the head 75 is fixedly connected to a tension spring 76. One end of the tension spring 76 is fixedly connected to one end of the inner wall of the cylinder 71. A through hole 73 is arranged on the side wall of the cylinder 71. The through hole 73 penetrates the side wall of the cylinder 71. At one end of the cylinder 71, notches 72 are arranged at equal distances around the axis of the cylinder 71.

[0027] According to the above structure, when the top plate 41 moves forward, the tension spring 76 is stretched. After the toothless part 64 rotates below the rack 43, the tension spring 76 contracts to pull the top plate 41 back. When the end 75 moves to the end of the notch 72, the air inside the cylinder 71 is discharged through the through hole 73. Since the aperture of the through hole 73 is small, the air inside the cylinder 71 is compressed at this time, and the air can generate a pressure on the end 75, thereby reducing the return speed of the end 75 and the entire mounting assembly 4. After the entire mounting assembly 4 returns to the corresponding position, it stops. When the gear 63 meshes with the rack 43 again, the mounting assembly 4 is driven to move forward again for the next hot pressing.

[0028] The working principle of the present utility model is as follows: During use, the base layer and the surface layer of the copper clad laminate are sequentially placed inside a number of copper clad laminate molds 3, and the copper clad laminate is conveyed forward by the plate chain conveyor 2. After the copper clad laminate is conveyed below the heating assembly 5, the reduction motor 65 drives the gear 63 to rotate. The gear 63 is meshed and connected with the rack 43, thereby driving the top plate 41 to move. The setting of the two heating assemblies 5 can heat and hot press two copper clad laminates simultaneously and provide corresponding time for the entire mounting assembly 4 to return. During heating, the electric telescopic rod 51 extends, and the electric heating plate 52 contacts the surface layer of the copper clad laminate to heat the surface layer and hot press the surface layer onto the base layer. After the hot pressing is completed, the electric telescopic rod 51 contracts and the electric heating plate 52 rises. When the top plate 41 moves forward, the tension spring 76 is stretched. When the toothless part 64 on the gear 63 rotates to contact the bottom end of the rack 43, the entire mounting assembly 4 can return under the drive of the buffer assembly 7. The tension spring 76 contracts to pull the top plate 41 back. When the end 75 moves to the end of the notch 72, the air inside the cylinder 71 is discharged through the through hole 73. Since the aperture of the through hole 73 is small, the air inside the cylinder 71 is compressed at this time, and the air can generate a pressure on the end 75, thereby reducing the return speed of the end 75 and the entire mounting assembly 4. After the entire mounting assembly 4 returns to the corresponding position, it stops. When the gear 63 meshes with the rack 43 again, the mounting assembly 4 is driven to move forward again for the next hot pressing.

[0029] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in this field without special description and limitation.
