Description

Technical Field

[0001] The invention relates to the technical field of copper clad laminate coating, and in particular to a copper clad laminate coating heating rapid prototyping device. Background Art

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

[0003] In the prior art, after a plurality of copper clad laminates are stacked into a "plate stack", the "plate stack" is generally coated manually. During the coating process, the adhesive film is not tightly enough attached to the "plate stack", so that a large gap exists between the adhesive film and the surface of the "plate stack", which makes the copper clad laminates after coating have space to shift, thereby posing a risk of mutual friction and wear during subsequent transportation. Summary of the invention

[0004] The object of the present invention is to provide a copper clad laminate film heating rapid prototyping device, which can make the film tightly cover the "plate stack", so as to avoid the copper clad laminates from rubbing against each other and wearing during subsequent transportation.

[0007] Specifically, the screw mechanism is provided with a screw motor, a motor shaft of the screw motor is connected with a screw, a screw nut is fixedly connected with the longitudinal slide seat, and the screw nut is threadedly connected with the screw.

[0008] Specifically, the lifting frame includes a square frame portion and two frame ears. The square frame portion and the two frame ears are hollow and connected to each other.

In addition, hot air is used to soften and stretch the coating, and the cooling and shrinkage of the coating is utilized to tightly wrap the coating around the four side walls and top wall of the "plate stack".

[0021] Specifically, the longitudinal slide 51 is in an inverted T-shape, thereby forming a mounting plate 511 , and the two lifting cylinders 52 are fixedly connected to the mounting plate 511 .

[0022] Specifically, the screw mechanism 5 is provided with a screw motor 53 , a motor shaft of the screw motor 53 is connected with a screw, a screw nut 512 is fixedly connected to the longitudinal slide 51 , and the screw nut 512 is threadedly connected to the screw.

[0023] 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 connected to each other.

[0024] Specifically, both sides of the bottom wall of the pressing frame 7 are provided with gaps 701 to avoid air leakage, so that the bottom of the pressing frame 7 forms a square ring-shaped pressing platform 702 .

[0026] Specifically, an air inlet is provided on the top wall of the oven 32, and the blowing fan 322 is provided at the lower side of the air inlet.

[0027] Specifically, the conveying belt of the coating conveying device 4 is higher than the conveying belt of the bubble film conveying device 2 , and the conveying direction of the coating conveying device 4 is opposite to that of the bubble film conveying device 2 .

[0028] The working process of the copper clad laminate film heating rapid prototyping equipment of the present invention is as follows: S1: Multiple copper clad laminates are stacked, and a piece of cardboard is set on the lower side of the bottom copper clad laminate, and a piece of cardboard is set on the upper side of the top copper clad laminate, forming a "plate stack 11". Multiple "plate stacks 11" are sequentially conveyed forward by the plate stack conveying device 1 (not shown in the figure).

[0029] S2: When a certain "plate stack 11" reaches the front extreme position of the plate stack conveying device 1, the "plate stack" is restricted by a limiting block (provided in the plate stack conveying device 1, not shown in the figure) and stops moving forward.

[0030] S3: See Figure 3 The bubble film conveying device 2 conveys the bubble film 8. The robot (not shown) transfers the "plate stack 11" that is stagnant on the limit block (not shown) to the bubble film 8, referring to Figure 3 .

[0031] S4: The "plate stack 11" and the bubble film 8 are transported forward by the bubble film transport device 2 until the "plate stack 11" reaches the film coating station ( Figure 1 When the bubble film conveying device 2 stops conveying, the "plate stack 11" stays at the film coating station (such as Figure 3 Then, the four pressing cylinders 21 contract, so that the pressing frame 7 moves down to the square ring-shaped pressing platform 702 to press the bubble membrane 8 around the "plate stack 11", so that the bubble membrane 8 around the "plate stack 11" remains flat.

[0032] S5: The film conveying device 4 conveys the film 41. The four lifting cylinders 52 jointly drive the lifting frame 6 to move up to a height higher than the belt of the film conveying device 4. Then, the screw mechanism 5 drives the longitudinal slide 51 to move to the film conveying device 4, so that the lifting frame 6 is on the upper side of the belt surface of the film conveying device 4. Then, the negative pressure device (not shown) connected to the suction pipe 62 is started, so that the suction hole 61 sucks air to form a negative pressure. Then, the lifting frame 6 moves down, so that the multiple suction holes 61 jointly absorb a piece of film 41 (refer to Fig. 9 ).

[0033] S6: The horizontal cylinder 313 extends outward, driving the oven 32 to move forward to the film coating station ( Figure 1Then, the screw mechanism 5 drives the longitudinal slide 51 to move to the film coating station, so that the lifting frame 6 and the film 41 move to the bottom of the oven 32. Then, the electric heating wire 321 works to generate heat, and the blowing fan 322 blows air downward, and the hot air is blown downward to the upper side of the film 41, so that the film 41 is softened by heat and blown into a downward protruding pocket shape (such as Figure 8 as shown).

[0034] S7: The heating wire 321 stops, the blowing fan 322 stops blowing, and the horizontal cylinder 313 retracts to make the oven 32 retreat. At the same time, the four lifting cylinders 52 contract, thereby driving the lifting frame 6 to move downward until the lifting frame 6 is close to the upper side of the opening edge of the pressing frame 7. At this time, the suction hole 61 of the lifting frame 6 no longer inhales air, and the exhaust hole 71 starts to inhale air to discharge the gas on the lower side of the coating 41, so that the coating 41 can be more closely attached to the top wall of the "plate stack 11". In this process, the bottom side of the coating 41, which was originally softened and stretched by heat, is close to the top wall of the "plate stack 11". The coating 41 shrinks rapidly due to cooling, so that the middle part of the coating 41 tightly covers the top wall and four side walls of the "plate stack 11", and the outer peripheral edge of the coating 41 is folded outward and close to the top wall of the bubble film 8.

[0035] In this way, the preliminary coating of the "plate stack 11" is completed, and the peripheral edge of the coating 41 will be further folded to the bottom wall of the "plate stack 11" in the subsequent process, thereby achieving the coating of the entire "plate stack 11" for subsequent transportation.

[0036] The above-mentioned preliminary coating process uses the lifting frame 6 to absorb the coating 41 and realize the coating, which has a high degree of automation. In addition, hot air is used to soften the coating 41 and stretch it, and the cooling and rapid shrinkage of the coating 41 are used to tightly wrap the coating 41 on the top wall and four side walls of the "plate stack 11". The process is efficient and fast, and the coating is tight, so that each copper-clad plate in the "plate stack 11" is close to each other. Furthermore, when the lifting frame 6 descends to abut against the top wall of the pressing frame 7, the exhaust holes 71 provided in the pressing frame 7 quickly absorb the gas on the bottom side of the coating 41, that is, the inner side of the pressing frame 7, thereby accelerating the cooling and shrinkage of the coating 41, ensuring that the coating 41 shrinks at a very fast speed, thereby tightly covering the top wall and four side walls of the "plate stack 11" to ensure the coating quality.

Although the present invention has been disclosed as above in the form of preferred embodiments, it is not intended to limit the present invention.
