Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flexible copper clad laminate manufacturing equipment, and particularly relates to an edge pressing device for a flexible copper clad laminate in a curing furnace. Background Art
[0002] As the basic material of printed circuit boards, copper clad laminates play an important role in the electronics industry. Among them, flexible copper clad laminates have been widely used in wearable devices and other electronic products that require bending or folding due to their good flexibility, light weight, and bending resistance. To ensure that the coating on the flexible copper clad laminate can adhere to the substrate, it is usually necessary to heat and cure the flexible copper clad laminate through a curing furnace.
[0003] However, when processing flexible copper clad laminates in a curing furnace with a high-temperature environment, warping may occur at the edges due to reasons such as the mismatch between the thermal expansion coefficients of the material and the copper foil, resulting in uneven stress on the copper clad laminate during the curing process, and further leading to appearance quality problems such as wrinkles, corrugations, and uneven edges of the product; if the warping degree of the flexible copper clad laminate is severe, it may not be able to be wound and unwound normally, thus unable to continue subsequent processing, reducing production efficiency, and increasing the scrap rate.
[0004] As Figure 1 shown, when the applicant tried to solve the problem of edge warping of flexible copper clad laminates, one method was to select to let the copper clad laminate interweave up and down between rotating shafts in the transmission path, and suppress edge warping by applying appropriate tension. However, due to the speed differences in the transmission system and the deformation of the rotating shafts themselves, the transmission speeds of each transmission rotating shaft are inconsistent and there are different degrees of vibration and jogging, still possibly resulting in wrinkles on the surface of the flexible copper clad laminate, reducing the product quality, and even unable to meet the production standards. Summary of the Utility Model

[0024] As Figures 2 to 5 shown, the present utility model discloses a flexible copper clad laminate edge pressing device for a curing furnace, including a conveying frame 1.

A pressing wheel 4 capable of pressing the edge of the copper clad laminate is rotatably connected to the adjusting frame 3. The pressing wheel 4 is located above the conveying rotating shaft 2. A first adjusting mechanism 5 capable of adjusting the position of the pressing wheel 4 in the left-right direction and a second adjusting mechanism 6 capable of adjusting the distance between the pressing wheel 4 and the conveying rotating shaft 2 are further provided on the adjusting frame 3.
[0025] The conveying frame 1 is used to carry and convey the copper clad laminate. It has a plurality of conveying rotating shafts 2 arranged in parallel, so as to ensure that the copper clad laminate moves along the conveying direction in a straight line and maintain the stable state of the copper clad laminate during the conveying process. The adjusting frame 3 is rotatably connected with the pressing wheel 4, and the first adjusting mechanism 5 and the second adjusting mechanism 6 are provided to provide an adjusting function for the pressing wheel 4. Through the rolling of the pressing wheel 4, it is ensured that the pressure is evenly distributed on the edge of the copper clad laminate to prevent warping. The first adjusting mechanism 5 can adjust the position of the pressing wheel 4 in the left-right direction to adapt to copper clad laminates of different widths. The second adjusting mechanism 6 can adjust the distance between the pressing wheel 4 and the conveying rotating shaft 2 to adapt to copper clad laminates of different thicknesses.
[0026] By arranging a rotatable pressing wheel 4 on the adjusting frame 3, the pressing wheel 4 can press the edge of the copper clad laminate during the transmission process, enabling the copper clad laminate to maintain better flatness throughout the transmission process and reducing quality problems such as wrinkles and ripples. By arranging a first adjusting mechanism 5 that can adjust the position of the pressing wheel 4 in the left-right direction, it can adapt to copper clad laminates of different widths, ensuring that the pressing wheel 4 can effectively contact and press the edge of the copper clad laminate according to the copper clad laminate. By arranging a second adjusting mechanism 6 that can adjust the distance between the pressing wheel 4 and the transmission rotating shaft 2, the pressing force can be adjusted according to the actual situation to adapt to copper clad laminates of different thicknesses or characteristics.
[0027] The second adjusting mechanism 6 includes a seat body 61 and a lifting frame 62 that is slidably connected to the seat body 61 in the up-down direction and can drive the pressing wheel 4 to move in the up-down direction. A first locking member 63 is provided between the seat body 61 and the lifting frame 62 to lock the two.
[0028] The seat body 61 provides support for the lifting frame 62 and ensures that it can slide in the up-down direction. The lifting frame 62 can drive the pressing wheel 4 to move in the up-down direction. By moving the lifting frame 62 up and down, the distance between the pressing wheel 4 and the transmission rotating shaft 2 can be adjusted. The first locking member 63 can be realized by a bolt fastener. By tightening or loosening the bolt fastener, the seat body and the lifting frame can be locked or released. It can also be realized by a buckle method. By the acting force of a spring, the buckle is matched with the holes or grooves on the seat body 61 or the lifting frame 62 to lock the position. It can also be realized by hydraulic or pneumatic locking, handle locking, magnetic locking, etc. The first locking member 63 can lock the relative position between the seat body 61 and the lifting frame 62, prevent sliding during the working process, and ensure that the position of the pressing wheel 4 will not change in the up-down direction after the distance is adjusted.
[0029] The first adjusting mechanism 5 includes a sliding rod 51 connected to the lifting frame 62 and arranged in the left-right direction. A support frame 52 is slidably connected to the sliding rod 51. A rotating rod 53 extending along the direction of the transmission frame 1 is provided on the support frame 52. The pressing wheel 4 is arranged on the rotating rod 53. A second locking member 54 is provided between the sliding rod 51 and the support frame 52 to lock the two.
[0030] The sliding rod 51 is arranged in the left - right direction. The support frame 52 is slidably connected to the sliding rod 51, and a rotating rod 53 is provided on the support frame 52 and extends along the direction of the conveyor frame 1, ensuring that the pressing wheel 4 on the rotating rod 53 can cover the edge of the copper - clad laminate. By adjusting the position of the support frame 52 that can slide left - and - right along the sliding rod 51, the position of the pressing wheel 4 in the left - right direction can be adjusted. The second locking member 54 can be realized by a bolt fastener. By tightening or loosening the bolt fastener, the sliding rod 51 and the support frame 52 can be locked or released; it can also be realized by a snap - fastener. By the acting force of a spring, the snap - fastener is engaged with the holes or grooves on the sliding rod 51 or the support frame 52 to lock the position; it can also be realized by hydraulic or pneumatic locking, handle locking, magnetic locking, etc. The second locking member 54 can lock the relative position between the sliding rod 51 and the support frame 52 to prevent sliding during the working process.
[0031] A fixing member 7 for maintaining the relative position between the pressing wheel 4 and the conveyor rotating shaft 2 is further provided on the rotating rod 53.
[0032] The fixing member 7 can maintain the relative position between the pressing wheel 4 and the conveyor rotating shaft 2, ensuring that the pressing wheel 4 does not move relatively after the position is adjusted.
[0033] The fixing member 7 is a fixing block, and a fixing opening 71 matching the shaft diameter of the conveyor rotating shaft 2 is provided on the fixing member 7.
[0034] By the matching of the fixing opening 71 on the fixing block 7 with the shaft diameter of the conveyor rotating shaft 2, the relative position between the pressing wheel 4 and the conveyor rotating shaft 2 is fixed.
[0035] The shape of the fixing opening 71 is U - shaped.
[0036] The U - shaped fixing opening 71 design makes it easy for the fixing block 7 to be sleeved on the conveyor rotating shaft 2, facilitating installation and disassembly. At the same time, the U - shaped fixing opening 71 can adapt to conveyor rotating shafts 2 with different diameters, ensuring that the pressing wheel 4 is stable in position during the working process and is not prone to sliding or deviation.
[0037] The fixing member 7 can also maintain the relative position between the pressing wheel 4 and the conveyor rotating shaft 2 in other ways. For example, the rotating rod 53 is provided with a positioning hole and a positioning pin whose one end can cooperate with the positioning hole, and a positioning plate is further provided on the seat body 61, and the other end of the positioning pin can be inserted into the positioning plate.
[0038] An avoidance rod 8 for staggering the fixing member 7 and the sliding rod 51 in the up - down direction is provided between the support frame 52 and the rotating rod 53.
[0039] The design of the avoidance rod 8 provides sufficient space between the fixing member 7 and the sliding rod 51 to avoid collision or interference between the two during the adjustment process.
[0040] Compared with the transmission path in which the copper clad laminate is arranged vertically and horizontally between the rotating shafts 2, in the copper clad laminate transmission path of the present invention, the transmission shaft 2 is only used for support, avoiding vibration and jogging problems caused by inconsistent transmission speeds; the transmission path is more stable, reducing failures caused by transmission shaft problems and improving the reliability of the entire system; the transmission shaft is only used for support, reducing complex transmission structures and lowering the maintenance difficulty; the consistency of the transmission path is better, effectively solving the wrinkle problem on the surface of the flexible copper clad laminate and improving the surface quality of the product.
