Description

Technical Field

[0001] The utility model relates to the technical field of printed circuit boards, in particular to a dry film hole covering device. Background Art

[0002] Dry film capping is to seal the holes of the circuit board with dry film material, which can effectively prevent the circuit components on the circuit board from being affected by the outside world and achieve the purpose of dustproof, moisture-proof and corrosion-proof. The dry film material is a polyimide film with high strength, high viscosity, high temperature tolerance and chemical stability. It can melt at high temperature and form a strong bond with the surface of the circuit board.

[0003] When applying dry film to a circuit board, the circuit board is usually placed on a conveyor for transportation. When the circuit board is transported to the bottom of the film-applying mechanism, it is subjected to the film-applying process. However, since the conveyor device will inevitably vibrate during operation, it is easy to cause the circuit board to shift in position during the transportation process, resulting in reduced film-applying accuracy and even the need for rework, which adds additional processes and increases production costs. Utility Model Content

[0004] The utility model aims to provide a dry film hole covering device with high film sticking accuracy.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A dry film hole covering device comprises a conveying device, two limit plates are symmetrically arranged on the upper side of the conveying device, a plurality of guide rods are rotatably installed on the lower surface of the limit plates, two side blocks are respectively installed on both sides of the upper surface of the conveying device, and an adjustment mechanism capable of adjusting the distance between the two limit plates is arranged on the side blocks; a vertical plate is installed on the upper surface of the conveying device, a film sticking mechanism is arranged on the upper side of the vertical plate, a first electric push rod is installed on the outer surface of the vertical plate, an installation box is installed at the end of the telescopic end of the first electric push rod, brackets are arranged on both sides of the installation box, a clamping plate is arranged at the end of the bracket, and a correction mechanism capable of simultaneously driving the two brackets to move closer to or away from each other is arranged inside the installation box.

[0007] It can be seen that by setting the limit plate and the guide rod, the two sides of the circuit board can be limited so that it can be conveyed forward in a stable direction and angle. When the circuit board is conveyed to the lower side of the film-laminating mechanism, the conveying device suspends conveying, and then the two clamps are driven by the correction mechanism to approach the circuit board from the other two sides of the circuit board, and the position of the circuit board is corrected to prevent the circuit board from sliding forward due to inertia when the conveying device stops running. The circuit board can then be placed in a position that precisely corresponds to the film-laminating mechanism, thereby improving the film-laminating accuracy, ensuring product quality, avoiding additional rework processes, and reducing production costs. In addition, the spacing between the two limit plates can be adjusted by setting the adjustment mechanism, which is suitable for circuit boards of different specifications.

[0008] Furthermore, the adjustment mechanism includes a bidirectional threaded rod rotatably installed between two opposite side blocks, and one end of the bidirectional threaded rod passes through the outside of the side block, two nuts are symmetrically installed on the outer surface of the bidirectional threaded rod, a first connecting block is installed on the outer surface of the nut, and the end of the first connecting block is connected to the limit plate; a pulley group is arranged for transmission between the ends of the two bidirectional threaded rods, and a handwheel is installed on the end of one of the bidirectional threaded rods.

[0009] When it is necessary to adjust the distance between the two limit plates, the hand wheel can be rotated. Through the transmission action of the pulley group, the two bidirectional threaded rods can be driven to rotate at the same time. The rotation of the bidirectional threaded rods drives the two nuts installed on the surface thereof to move inward or outward at the same time, and through the connection action of the first connecting block, the two limit plates are driven to move, thereby achieving the purpose of adjusting the distance.

[0010] Furthermore, the correction mechanism includes a gear rotatably installed inside the installation box, and L-shaped toothed plates are slidably installed on the upper and lower inner walls of the installation box, and the long arm of the L-shaped toothed plate is meshed and connected with the gear, and the short arm of the L-shaped toothed plate is connected to the bracket, and a second electric push rod is installed inside the installation box, and the end of the telescopic end of the second electric push rod is connected to one of the L-shaped toothed plates.

[0011] When the circuit board moves to the bottom of the film sticking mechanism, the first electric push rod is started first to drive the installation box and the clamping plate to descend, so that the two clamping plates are respectively located on both sides of the circuit board, and then the second electric push rod is started, which drives the L-shaped toothed plate connected to it to move, and through the transmission action of the gears, the two L-shaped toothed plates can move synchronously, and then the two clamping plates can be driven to approach both sides of the circuit board at the same time through the connection action of the bracket, and their positions can be corrected to ensure the film sticking accuracy of the film sticking mechanism.

[0012] Furthermore, a mounting plate is installed at the end of the bracket, a telescopic rod is installed on the outer surface of the mounting plate, and the end of the telescopic rod is connected to the clamping plate. A spring is sleeved on the outer surface of the telescopic rod, and both ends of the spring are respectively abutted against the mounting plate and the clamping plate.

[0013] The spring can play a buffering role when the clamping plate contacts the circuit board, thereby avoiding damage to the circuit board caused by hard contact.

[0014] Furthermore, a slide bar is connected between the two side blocks, a length scale is provided on the outer surface of the slide bar, a movable ring is sleeved on the outer surface of the slide bar, a second connecting block is installed on the outer surface of the movable ring, and the end of the second connecting block is connected to the nut.

[0015] When the distance between the two limit plates is adjusted through the adjustment mechanism, the nut drives the movable ring to slide on the surface of the slide rod, and then the distance between the two limit plates can be accurately adjusted according to the length scale.

[0016] Furthermore, a slide rail is vertically installed on the outer surface of the vertical plate, and a slide groove is opened on the outer surface of the installation box, and the slide groove is adapted to the slide rail.

[0017] The stability of the installation box during lifting and lowering can be improved by arranging the slide rails and the slide grooves. BRIEF DESCRIPTION OF THE DRAWINGS
