Description

Technical Field

[0001] This utility model relates to the field of coating of reverse copper foil, specifically a coating processing device for reverse copper foil substrate. Background Technology

[0002] Reversible copper foil substrate is a widely used material in circuit board manufacturing. Its core material is reverse copper foil, which is a copper foil with the rough surface reversed and the smooth surface roughened and enhanced.

[0003] In existing technologies, U-shaped coating rollers are generally used to coat the roughened surface of copper foil. In existing technologies, one way to adjust the coating pressure and thickness is to adjust the distance between the coating roller and the flipped copper foil substrate. There are many existing adjustment methods. However, during the adjustment process, the movement range of the coating roller within a unit (e.g., one second) is relatively large, which makes it inconvenient to make precise adjustments. Utility Model Content

[0004] The purpose of this invention is to provide a reverse copper foil substrate coating processing device in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reverse copper foil substrate coating processing device, comprising a fixed base plate, with upwardly protruding guide slides welded to both sides of the top of the fixed base plate, and lifting sliders slidably mounted on the outer walls of the guide slides. Rotating shafts are rotatably mounted inside both lifting sliders, and coating rollers are fixedly mounted at the ends of the two rotating shafts that are close to each other. Multiple glue grooves are equidistantly spaced on the outer circumference of the coating rollers. A rotary motor is mounted on the outer side of one of the lifting sliders via a bracket, and the output shaft of the rotary motor is coaxially and fixedly connected to one of the rotating shafts. A lifting mechanism that synchronously drives the two lifting sliders to move upwards is mounted on the top of the fixed base plate.

[0006] As a further embodiment of this utility model: the lifting mechanism includes a worm gear rotatably mounted on the top center of the fixed base plate via a support frame, a forward and reverse motor is mounted on the outside of the support frame, the output shaft of the forward and reverse motor is coaxially fixedly connected to the center of one end of the worm gear, a worm wheel is designed above the outer periphery of the worm gear, and the helical part of the worm gear meshes with the teeth of the worm wheel.

[0007] As a further embodiment of this utility model: a synchronous shaft extending along the length of the fixed base plate is assembled at the center of the worm gear. Rotary gears are coaxially fixedly installed at both ends of the synchronous shaft. A lifting rack meshes with the outer side of the rotating gear. The top end of one lifting rack is fixedly connected to the bottom end of one lifting slider. Multiple fixed support frames are fixedly installed on the top of the fixed base plate.

[0009] As a further embodiment of this utility model: the bottom end of the fixing rod matches the outer periphery of the coating roller, and the holding box is used to hold the coating adhesive.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3In this embodiment of the present invention, a reverse copper foil substrate coating processing device includes a fixed base plate 1. Guide slide rods 7 protruding upwards are welded to both sides of the top of the fixed base plate 1. Lifting sliders 6 are slidably mounted on the outer wall of the guide slide rods 7. Rotating shafts are rotatably mounted inside each of the two lifting sliders 6. Coating rollers 10 are fixedly mounted at the ends of the two rotating shafts that are close to each other. Multiple glue grooves 12 are equidistantly opened on the outer circumference of the coating rollers 10. A rotary motor 11 is mounted on the outer side of one lifting slider 6 via a bracket. The output shaft of the rotary motor 11 is coaxially and fixedly connected to one of the rotating shafts. A lifting mechanism that synchronously drives the two lifting sliders 6 to move upwards is mounted on the top of the fixed base plate 1.

[0018] In this embodiment: First, the drive roller moves the copper foil substrate from below the coating roller 10. The S-side of the copper foil (i.e., the original smooth surface after roughening treatment) is then transferred to the surface of the coating roller 10 by the rotating motor 11 during rotation. The rotating coating roller 10 then brings the coating adhesive into contact with the S-side of the copper foil. When it is necessary to change the amount of coating adhesive by adjusting the height of the coating roller 10, the lifting mechanism is activated. The lifting mechanism moves the coating roller 10 in the vertical direction, thereby adjusting the distance between the coating roller 10 and the copper foil substrate.

[0019] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The lifting mechanism includes a worm gear 14 rotatably mounted on the top center of a fixed base plate 1 via a support frame. A forward and reverse motor 13 is mounted on the outside of the support frame. The output shaft of the forward and reverse motor 13 is coaxially fixedly connected to the center of one end of the worm gear 14. A worm wheel 15 is designed on the upper outer periphery of the worm gear 14. The helical part of the worm gear 14 meshes with the teeth of the worm wheel 15. A synchronous shaft 3 extending along the length of the fixed base plate 1 is mounted at the center of the worm wheel 15. Rotary gears 4 are coaxially fixedly mounted on both ends of the synchronous shaft 3. A lifting rack 5 meshes on the outside of the rotating gear 4. The top end of one lifting rack 5 is fixedly connected to the bottom end of one lifting slider 6. Multiple fixed support frames 2 are fixedly mounted on the top of the fixed base plate 1. The multiple fixed support frames 2 are rotatably connected to the synchronous shaft 3.

[0020] In this embodiment: when adjusting the height of the coating roller 10 to adjust the distance between the coating roller 10 and the copper foil substrate, the forward and reverse motor 13 is started. The forward and reverse motor 13 drives the worm gear 14 to rotate. The spiral part of the rotating worm gear 14 drives the teeth of the worm wheel 15 to rotate. The rotating worm gear 15 drives the synchronous shaft 3 to rotate. When the synchronous shaft 3 rotates, it drives the rotating gears 4 at both ends to rotate. The rotating gears 4 drive the lifting rack 5 to move in the vertical direction. The lifting rack 5 drives the lifting slider 6 connected to it to move up and down along the guide slide 7. At the same time, the lifting slider 6 synchronously drives the coating roller 10 and the holding box 9 to move synchronously in the vertical direction, so as to achieve the purpose of adjusting the height of the coating roller 10.

[0021] During the above process, the rotating worm 14 rotates one revolution, driving the tooth block of the worm wheel 14 to rotate one tooth position. The worm 14 then drives the two rotating gears 4 to rotate through the synchronous shaft 3. This can prevent the rotating gears 4 from rotating too fast and keep the rotating gears 4 at a low speed, so as to realize the slow adjustment of the lifting rack 5 in the vertical direction.

[0022] Please refer to this carefully. Figure 1 and Figure 2 The top of the lifting slider 6 is welded with a fixing rod 8. The inner sides of the two fixing rods 8 are welded to the ends of the holding box 9. The bottom end of the fixing rod 8 matches the outer periphery of the coating roller 10. The holding box 9 is used to hold the coating adhesive.

[0023] In this embodiment: when the coating roller 10 rotates, the coating adhesive inside the container 9 can come into contact with the surface of the coating roller 10, thereby achieving the purpose of transferring the coating adhesive.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
