Technical Field

[0001] The utility model relates to the field of copper clad laminate treatment, and more specifically, to a flatness detection device for copper clad laminates. Background Art

[0002] A flatness detection device for copper clad laminates is a device used to detect the flatness of the surface of copper clad laminates, mainly ensuring that the flatness of copper clad laminates meets specific standards through high-precision detection techniques. This device is particularly important for the printed circuit board manufacturing industry because the flatness of copper clad laminates directly affects the quality and function of circuit boards.

[0003] Currently, when the existing flatness detection device for copper clad laminates is in use, the copper clad laminate needs to be placed below the detection device and the flatness is detected by laser; however, after the copper clad laminate is placed flat below the detection device, only one side of the copper clad laminate can be detected, and at the same time, during the detection process of the copper clad laminate, the detection angle cannot be adjusted, so there will be some errors in the detection; how to improve these problems has become an urgent problem for those skilled in the art to solve. Summary of the Utility Model

The vertical plate is fixedly connected to the inner wall of the detection bin, the collar is fixedly connected to the top of the vertical plate, the gear is arranged outside the collar, and the rack is arranged outside the gear.

[0014] Preferably, the gear penetrates through the collar and is rotatably connected to the inner wall of the collar. The gear is fixedly connected to the clamping member, and the gear meshes with the rack.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0030] Referring to Figures 1 - 5 , a flatness detection device for a copper clad laminate, comprising a detection chamber 1, a conveyor belt 2 installed on the outer wall of the detection chamber 1, a clamping member 3 installed inside the detection chamber 1, a guide rail 4 installed inside the detection chamber 1, and a detection lamp 5 installed on the outer wall of the guide rail 4. An angle adjustment assembly 6 is provided inside the detection chamber 1. The angle adjustment assembly 6 consists of a moving unit and a rotating unit. The moving unit is located inside the detection chamber 1, and the rotating unit is located inside the detection chamber 1.

[0031] The moving unit includes a vertical rod 601, a fixed frame 602, a spring push rod 603, a connecting block 604, an inclined rod 605, and a moving frame 606. The vertical rod 601 is fixedly connected to the inner wall of the detection chamber 1. The fixed frame 602 is fixedly connected to the outer wall of the vertical rod 601. The spring push rod 603 is fixedly connected to the outer wall of the fixed frame 602. The connecting block 604 is fixedly connected to the output end of the spring push rod 603. The inclined rod 605 is disposed on the outer wall of the connecting block 604, and movable members are installed at both ends of the inclined rod 605. The moving frame 606 is installed on the outer wall of the vertical rod 601. The inclined rod 605 is connected to the connecting block 604 and the moving frame 606 through the movable members respectively. When the connecting block 604 moves, it can push the inclined rod 605 to move the moving frame 606. The inner wall of the moving frame 606 is slidably connected to the outer wall of the vertical rod 601, and the moving frame 606 can slide on the outer wall of the vertical rod 601.

[0032] The rotating unit includes a vertical plate 607, a collar 608, a gear 609, and a rack 610. The vertical plate 607 is fixedly connected to the inner wall of the detection chamber 1. The collar 608 is fixedly connected to the top of the vertical plate 607. The gear 609 is disposed outside the collar 608. The gear 609 penetrates the collar 608 and is rotatably connected to the inner wall of the collar 608. The gear 609 is fixedly connected to the clamping member 3. The gear 609 can rotate on the outer wall of the collar 608 and drive the clamping member 3 to rotate. The rack 610 is disposed outside the gear 609. The gear 609 meshes with the rack 610. When the rack 610 moves, it can drive the gear 609 to rotate.

[0033] By setting the gear 609 and the rack 610, when detecting that the lamp 5 moves on the outer wall of the guide rail 4, it will push the connecting block 604 to move, so that the inclined rod 605 pushes the rack 610 to move through the moving frame 606, causing the rack 610 to drive the gear 609 to rotate. The gear 609 will then drive the clamping member 3 to adjust the angle of the copper clad laminate, so that the inspection lamp 5 can detect the flatness of the copper clad laminate at different angles; this solves the problem that the angle of detection cannot be adjusted when detecting the flatness of the copper clad laminate.

[0034] The gear 609 is composed of a circular plate 6091, a bent rod 6092, gear teeth 6093, a bottom plate 6094 and a return spring 6095. The circular plate 6091 is arranged outside the collar 608. The bent rod 6092 is fixedly connected to the outer wall of the circular plate 6091. The gear teeth 6093 are arranged outside the circular plate 6091. The bent rod 6092 penetrates through the gear teeth 6093 and is rotatably connected to the gear teeth 6093. The gear teeth 6093 can rotate on the outer wall of the bent rod 6092. The bottom plate 6094 is fixedly connected to the outer wall of the circular plate 6091. The outer wall of the bottom plate 6094 abuts against the outer wall of the gear teeth 6093. The bottom plate 6094 can limit the angle of the gear teeth 6093. The return spring 6095 is fixedly connected to the outer wall of the circular plate 6091. The side of the return spring 6095 away from the circular plate 6091 is fixedly connected to the outer wall of the gear teeth 6093. The existence of the return spring 6095 can push the gear teeth 6093 to reset.

[0035] By setting the gear teeth 6093 and the return spring 6095, when the spring push rod 603 pushes the inclined rod 605 to reset, the moving frame 606 will drive the rack 610 to move. At this time, when the rack 610 resets, it will push the gear teeth 6093 to rotate around the bent rod 6092. When the rack 610 separates from the gear teeth 6093, the return spring 6095 will push the gear teeth 6093 to reset and abut against the bottom plate 6094. By limiting the angle of the gear teeth 6093 through the bottom plate 6094, the normal rotation of the gear 609 can be ensured.

[0036] The working principle of this copper clad laminate flatness detection device: The copper clad laminate is conveyed to the inside of the clamping member 3 through the conveyor belt 2. Control the operation of the inspection lamp 5 and the guide rail 4, so that the inspection lamp 5 slides on the outer wall of the guide rail 4 and presses the connecting block 604. At this time, the inclined rod 605 will, under the push of the connecting block 604, push the moving frame 606 to drive the rack 610 to move. When the rack 610 moves, it will drive the gear 609 to rotate. The gear 609 drives the clamping member 3 to rotate. When the inspection lamp 5 continuously presses the connecting block 604, the angle of the clamping member 3 will continuously change, facilitating the flatness detection of the copper clad laminate at different angles.

[0037] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
