[0029] The utility model provides Figures 1 to 6 The device for trimming and flattening a copper clad laminate for production shown in the figure comprises:

[0030] A conveying structure for conveying the copper-clad laminate after edge trimming;

[0031] The conveying structure includes a fixed frame 1, two sets of roller shafts 2 are rotatably connected at both ends of the inner cavity of the fixed frame 1 through bearings, two sets of parallel conveyor belts 3 are transmission-connected to the outer sides of the roller shafts 2, and a conveying motor 4 connected to the end of one set of roller shafts 2 is fixed to the outer side of the fixed frame 1;

[0032] and a plate 5 to be processed placed on top of the conveyor belt 3;

[0033] A first movable plate 6 and a second movable plate 7 are located at the upper and lower ends of the plate 5, and a pressing plate 8 for trimming the plate 5 is fixed to the front and rear ends of the first movable plate 6 and the second movable plate 7 on the opposite sides;

[0034] It also includes an adjustment component 9 for relatively moving the first movable plate 6 and the second movable plate 7, and a rotation component 10 for rotating the plate 5;

[0035] The plate 5 is conveyed and transferred by the conveying structure, and then the adjusting component 9 drives the first movable plate 6 and the second movable plate 7 to move toward each other, and the plate 5 is clamped by the extrusion plate 8, and then the rotating component 10 drives the plate 5 to rotate under the clamping of the extrusion plate 8, so that the warped edge of the cut edge of the plate 5 stretches outward to avoid direct flattening due to excessive warping curvature, and the warped edge is folded, which can effectively repair the cut edge of the copper clad laminate and ensure the subsequent normal processing of the copper clad laminate.

[0036] The adjustment component 9 includes a first electric push rod 91 fixed to the bottom of the inner cavity of the fixed frame 1, the piston rod of the first electric push rod 91 is fixed to the center of the bottom of the second movable plate 7, and rack plates 92 are fixed around the opposite sides of the first movable plate 6 and the second movable plate 7. An adjusting gear 93 is meshed on the opposite side of the rack plate 92. The adjusting gear 93 is installed inside a fixed seat 94 through a movable shaft, and the fixed seat 94 is fixed to the inner cavity of the fixed frame 1. The second movable plate 7 is raised and lowered by the first electric push rod 91, and then the first movable plate 6 and the second movable plate 7 are moved toward each other by using the rack plate 92 and the adjusting gear 93, so that the plate 5 is clamped by the extrusion plate 8.

[0037] The rotating assembly 10 includes a rotating motor 101 fixed to the top of the first movable plate 6. The output shaft of the rotating motor 101 passes through the first movable plate 6 and is fixed with a movable box 102. The inner cavity of the movable box 102 is fixed with a second electric push rod 103. The piston rod of the second electric push rod 103 passes through the movable box 102 and extends downward and is fixed with a turntable 104. The top of the second movable plate 7 is rotatably connected to a support column 105 through a bearing. A support frame 106 is fixed to the top of the support column 105. The support frame 106 is located directly below the turntable 104. The turntable 104 is ejected by the second electric push rod 103, and the plate 5 is clamped and fixed in cooperation with the support frame 106. Then, with the cooperation of the rotating motor 101, the plate 5 is rotated between the extrusion plates 8, so that the warped edges at the cut edges of the copper-clad plate are stretched outward under the action of the extrusion plates 8, so as to avoid the warped edges from folding during the flattening operation.

[0038] The bottom of the inner cavity of the fixed frame 1 is fixed with a limit frame 11, and the inner cavity of the limit frame 11 is movably provided with a baffle 12 for limiting the plate 5. A traction spring 13 is fixed to the bottom of the baffle 12, and one end of the traction spring 13 away from the baffle 12 is fixed to the inner cavity of the limit frame 11. The interior of the limit frame 11 is movably connected with an adjustment plate 14 through a movable shaft. One end of the adjustment plate 14 extends to the inner cavity of the limit frame 11 and is located below the baffle 12. A lower pressure column 15 is fixed to the bottom of the second movable plate 7, and the bottom of the lower pressure column 15 is located above the other end of the adjustment plate 14. The lower pressure column 15 is driven by the second movable plate 7 to squeeze one end of the adjustment plate 14, and the other end of the adjustment plate 14 is lifted up by the lever principle to block the plate 5, so as to facilitate the positioning of the plate 5 transported at the top of the conveyor belt 3. At the same time, the traction spring 13 can pull the baffle 12 downward after the lower pressure column 15 moves upward, so as to release the processed plate 5 and transfer the plate 5 by the conveyor belt 3.

[0039] The inner cavity of the support frame 106 is rotatably connected to multiple groups of support rollers 16 through bearings. The top of the support roller 16 is flush with the top of the extrusion plate 8 installed on the top of the second movable plate 7.

[0040] Support rods 17 are fixed on all four sides of the top of the turntable 104. The end of the support rods 17 away from the turntable 104 extends into the interior of the movable box 102. A rubber pad that increases friction is bonded to the bottom of the turntable 104. The setting of the support rods 17 facilitates the support of the turntable 104 to prevent the turntable 104 from shaking and affecting the stability of the plate 5. At the same time, the rubber pad can increase the friction between the turntable 104 and the plate 5, facilitates the rotation of the plate 5, and prevents the turntable 104 from causing scratches on the surface of the plate 5 during rotation.

[0041] Through holes are provided on the surfaces of the first movable plate 6 and the second movable plate 7, and the inner cavity of the through holes is slidably connected to the limiting column 18, and the bottom of the limiting column 18 is fixed to the inner cavity of the fixed frame 1. The first movable plate 6 and the second movable plate 7 can be limited by the limiting column 18 to ensure that the first movable plate 6 and the second movable plate 7 are relatively stable.

[0042] When in use, the trimmed plate 5 is transferred from the right side of the fixed frame 1 to the left through the conveyor belt. Before this, the first electric push rod 91 drives the second movable plate 7 to move downward, so that the lower pressure column 15 squeezes the adjustment plate 14, and then the other end of the adjustment plate 14 lifts up the baffle 12 to block the plate 5, and then the plate 5 is restricted between the first movable plate 6 and the second movable plate 7. Then the first electric push rod 91 drives the second movable plate 7 to move upward. At this time, the first movable plate 6 moves downward under the cooperation of the rack plate 92 and the adjusting gear 93, so that the squeezing plates 8 at the upper and lower positions contact the plate 5, and at the same time the lower pressure column 15 moves upward, so that the traction spring 13 drives The baffle 12 moves downward, and the sheet 5 is clamped by the extrusion plate 8 and falls off the conveyor belt. Then the second electric push rod 103 drives the turntable 104 to move downward, and the sheet 5 is clamped by the turntable 104 and the support frame 106. Then the rotating motor 101 drives the turntable 104 and the support frame 106 to rotate together with the sheet 5. When the edge of the sheet 5 contacts the extrusion plate 8, it stretches outward to reduce the flipping arc of the warped edge, so that the warped edge is flush with the sheet 5 under the extrusion of the extrusion plate 8. Then the first movable plate 6 and the second movable plate 7 move outward under the drive of the first electric push rod 91 to release the sheet 5, and the sheet 5 falls on the conveyor belt 3 again and is transferred to the left.
