Description

Technical Field

[0001] This invention relates to the field of copper clad laminate coating technology, specifically to a rapid prototyping equipment for copper clad laminate coating by heating. Background Technology

[0002] After the copper-clad laminates are produced, they need to be stacked into a "stack" and wrapped with adhesive film to ensure that the copper-clad laminates in the "stack" are tightly attached to each other, so as to avoid mutual friction and wear during subsequent transportation.

[0003] In existing technologies, after multiple copper-clad laminates are stacked into a "stack", the "stack" is usually wrapped manually. During the wrapping process, the adhesive film does not adhere tightly to the "stack", resulting in a large gap between the adhesive film and the surface of the "stack". This allows the copper-clad laminates to move around after wrapping, which poses a risk of mutual friction and wear during subsequent transportation. Summary of the Invention

[0004] The purpose of this invention is to provide a rapid prototyping equipment for copper clad laminates by heating, which can tightly wrap the laminates to prevent them from rubbing against each other and wearing out during subsequent transportation.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A rapid prototyping equipment for copper-clad laminate (CCL) coating includes a board stacking conveyor and a bubble wrap conveyor. The discharge end of the board stacking conveyor is located beside the bubble wrap conveyor. A hot air device and a coating conveyor are located above the bubble wrap conveyor. Screw mechanisms are located on both sides of the bubble wrap conveyor, each screw mechanism having a longitudinal slide. Each longitudinal slide has two lifting cylinders. The piston rods of the four lifting cylinders are all fixedly connected to a lifting frame. The lifting frame is a hollow frame, and its bottom wall has multiple suction holes. The lifting frame is connected to a suction pipe, suction holes, and suction... All pipes are connected to the inner cavity of the lifting frame. The bubble film conveying device is equipped with a wrapping station. Two pressing cylinders are fixed to both sides of the wrapping station. The piston rods of the four pressing cylinders are all fixed to a pressing frame. The pressing frame is a hollow frame. The inner wall of the pressing frame is equipped with an air extraction hole. The pressing frame is connected to an air extraction pipe. The air extraction hole and the air extraction pipe are both connected to the inner cavity of the pressing frame. The lifting frame can descend to rest against the upper side of the opening edge of the pressing frame. The hot air device includes a frame. The frame is slidably connected to an oven. The bottom wall of the oven is equipped with an opening and an electric heating wire. The top wall of the inner cavity of the oven is equipped with a blower.

[0007] Specifically, the longitudinal slide is in the shape of an inverted T, thus forming a mounting plate, to which two lifting cylinders are fixed.

[0008] Specifically, the lead screw mechanism is equipped with a lead screw motor, the motor shaft of the lead screw motor is connected to the lead screw, the longitudinal slide is fixedly connected to the lead screw nut, and the lead screw nut is threadedly connected to the lead screw.

[0009] Specifically, the lifting frame includes a square frame and two frame ears. The square frame and the two frame ears are hollow and connected to each other. The bottom wall of the square frame is provided with multiple air intake holes, which are arranged along the outline of the square frame. Both frame ears are provided with air intake pipes.

[0010] Specifically, the bottom wall of the clamping frame has clearance notches on both sides, so that the bottom of the clamping frame forms a square ring-shaped pressure platform.

[0011] Specifically, the frame is equipped with two crossbeams, and transverse guide rails are fixed to the bottom wall of the crossbeams. The oven is slidably connected to the two transverse guide rails. A transverse cylinder is fixed to the inner side of the crossbeams, and the piston rod of the transverse cylinder is fixed to the oven.

[0012] Specifically, the top wall of the oven is equipped with an air inlet, and the blower is located below the air inlet.

[0013] Specifically, the conveyor belt of the film-coating conveyor is higher than that of the bubble wrap conveyor, and the conveying direction of the film-coating conveyor is opposite to that of the bubble wrap conveyor.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] This invention employs a lifting frame to pick up and wrap the film, achieving a high degree of automation. Furthermore, hot air is used to soften and stretch the film, and the cooling and shrinkage of the film tightly wraps it around the four side walls and top wall of the "stacked boards." This process is highly efficient and fast, resulting in a tight and high-quality wrap. Moreover, when the lifting frame descends to rest against the top wall of the pressing frame, the air extraction holes in the pressing frame quickly draw away the gas from the bottom side of the film, i.e., the inside of the pressing frame, thereby accelerating the cooling and shrinkage of the film. This ensures that the film shrinks at an extremely fast speed, tightly wrapping the four side walls and top wall of the "stacked boards," thus guaranteeing the wrapping quality.

[0039] The bubble wrap conveying device 2 has screw mechanisms 5 on both sides. Each screw mechanism 5 has a longitudinal slide 51, and each longitudinal slide 51 has two lifting cylinders 52. The piston rods of the four lifting cylinders 52 are all fixedly connected to a lifting frame 6. The lifting frame 6 is a hollow frame.

[0040] The bubble wrap conveying device 2 is equipped with a wrapping station. Figure 1 At point A, two clamping cylinders 21 are fixedly connected to both sides of the coating station. A clamping frame 7 is fixedly connected to the top of the piston rods of all four clamping cylinders 21. The clamping frame 7 is a hollow frame with an air extraction hole 71 on its inner wall. An air extraction pipe 72 is connected to the clamping frame 7, and both the air extraction hole 71 and the air extraction pipe 72 communicate with the inner cavity of the clamping frame 7. The lifting frame 6 can descend to rest against the upper edge of the opening of the clamping frame 7. The hot air device 3 includes a frame 31, to which an oven 32 is slidably connected. The bottom wall of the oven 32 has an opening with a heating wire 321 at the opening, and a fan 322 is located on the top wall of the inner cavity of the oven 32.

[0041] Specifically, the longitudinal slide 51 is in the shape of an inverted T, thus forming a mounting plate 511, and two lifting cylinders 52 are fixed to the mounting plate 511.

[0042] Specifically, the lead screw mechanism 5 is equipped with a lead screw motor 53, the motor shaft of the lead screw motor 53 is connected to a lead screw, and the longitudinal slide 51 is fixedly connected to a lead screw nut 512, which is threadedly connected to the lead screw.

[0043] Specifically, the lifting frame 6 includes a square frame portion 601 and two frame ears 602. The square frame portion 601 and the two frame ears 602 are hollow and interconnected. The bottom wall of the square frame portion 601 is provided with a plurality of air intake holes 61, which are arranged along the outline of the square frame portion 601. Each of the two frame ears 602 is provided with an air intake pipe 62.

[0044] Specifically, the bottom wall of the clamping frame 7 is provided with clearance notches 701 on both sides, so that the bottom of the clamping frame 7 forms a square ring-shaped pressure platform 702.

[0045] Specifically, the frame 31 is provided with two crossbeams 312, and the bottom wall of the crossbeams 312 is fixedly connected to a transverse guide rail 311. The oven 32 is slidably connected to the two transverse guide rails 311. A transverse cylinder 313 is fixedly connected to the inner side of the crossbeams 312, and the piston rod of the transverse cylinder 313 is fixedly connected to the oven 32.

[0046] Specifically, the top wall of the oven 32 is provided with an air inlet, and the blower 322 is located below the air inlet.

[0047] Specifically, the conveyor belt of the film-coating conveyor 4 is higher than that of the bubble wrap conveyor 2, and the conveying direction of the film-coating conveyor 4 is opposite to that of the bubble wrap conveyor 2.

[0048] The working process of the copper-clad laminate coating heating rapid prototyping equipment of the present invention is as follows:

[0049] S1: Multiple copper-clad laminates are stacked, with a cardboard placed under the bottom copper-clad laminate and a cardboard placed on the top copper-clad laminate, forming a "lamb stack 11". Multiple "lamb stacks 11" are sequentially conveyed forward by the board stack conveyor 1 (not shown in the figure).

[0050] S2: When a certain "plate stack 11" reaches the front extreme position of the plate stack conveyor 1, the "plate stack" is restricted by the limiting position block (located in the plate stack conveyor 1, not shown in the figure) and stops moving forward.

[0051] S3: See Figure 3 The bubble wrap conveyor 2 conveys bubble wrap 8. A robotic arm (not shown) transfers the "stack of plates 11" stopped at a limiting block (not shown) onto the bubble wrap 8. (Refer to...) Figure 3 .

[0052] S4: The "stack of boards 11" and the bubble wrap 8 are conveyed forward by the bubble wrap conveying device 2 until the "stack of boards 11" reaches the wrapping station. Figure 1 When the bubble wrap conveyor 2 stops conveying at point A, the "stack of boards 11" remains at the wrapping station (e.g., at point A). Figure 3 (As shown). Then, the four pressing cylinders 21 contract, causing the pressing frame 7 to move down to the square annular pressing platform 702 to press the bubble film 8 around the "plate stack 11", so that the bubble film 8 around the "plate stack 11" remains flat.

[0053] S5: The laminating conveyor 4 conveys a laminating film 41. Four lifting cylinders 52 work together to move the lifting frame 6 upwards to a height above the belt of the laminating conveyor 4. Then, the lead screw mechanism 5 moves the longitudinal slide 51 to the laminating conveyor 4, positioning the lifting frame 6 above the belt surface of the laminating conveyor 4. Next, the negative pressure device (not shown) connected to the suction pipe 62 is activated, causing the suction holes 61 to draw in air and create negative pressure. Then, the lifting frame 6 moves downwards, allowing multiple suction holes 61 to simultaneously adsorb a single laminating film 41 (see reference). Figure 9 ).

[0054] S6: The horizontal cylinder 313 extends outward, driving the oven 32 forward to the wrapping station. Figure 1 Above (at point A in the middle). Then, the screw mechanism 5 drives the longitudinal slide 51 to move to the film coating station, thereby moving the lifting frame 6 along with the film coating 41 to below the oven 32. Then, the heating wire 321 works and heats up, and the fan 322 blows air downwards. The hot air generated blows downwards to the upper side of the film coating 41, thereby softening the film coating 41 by the heat and blowing it into a downward-protruding pocket shape (such as...). Figure 8 (As shown).

[0055] S7: The heating wire 321 stops, the fan 322 stops blowing air, and the horizontal cylinder 313 retracts, causing the oven 32 to retract. At the same time, the four lifting cylinders 52 retract, thereby driving the lifting frame 6 to move down until the lifting frame 6 is against the upper edge of the opening of the pressing frame 7. At this time, the air intake 61 of the lifting frame 6 stops drawing air, and the exhaust 71 begins to draw air to expel the gas under the film 41, so that the film 41 can adhere more tightly to the top wall of the "board stack 11". During this process, the bottom side of the film 41, which was originally softened and stretched by heat, is against the top wall of the "board stack 11". The film 41 shrinks rapidly due to cooling, so that the middle part of the film 41 tightly covers the top wall and four side walls of the "board stack 11", while the outer peripheral edge of the film 41 folds outward and adheres to the top wall of the bubble wrap 8.

[0056] In this way, the initial covering of the "stack of boards 11" is completed. The outer edge of the film 41 will be further folded to the bottom wall of the "stack of boards 11" in subsequent processes, thereby achieving the covering of the entire "stack of boards 11" for subsequent transportation.

[0057] The aforementioned preliminary coating process utilizes a lifting frame 6 to pick up the coating film 41 and achieve coating, resulting in a high degree of automation. Furthermore, hot air is used to soften and stretch the coating film 41, and its rapid contraction upon cooling tightly wraps the film 41 around the top and four side walls of the "board stack 11." This process is highly efficient and fast, ensuring a tight wrapping and bringing the copper-clad laminates in the "board stack 11" close together. Moreover, as the lifting frame 6 descends to rest against the top wall of the pressing frame 7, the air extraction holes 71 in the pressing frame 7 quickly draw away the gas from the bottom side of the coating film 41, i.e., the inside of the pressing frame 7, thereby accelerating the cooling and contraction of the coating film 41. This ensures that the coating film 41 contracts at an extremely fast speed, tightly wrapping the top and four side walls of the "board stack 11" to guarantee coating quality.
