Description

Technical Field

[0001] This application relates to the technical field of circuit board manufacturing and processing, and in particular to an automatic circuit board cutting device. Background Technology

[0002] Circuit boards are indispensable components in electronic devices, serving as the carriers for electrical connections between electronic components. The manufacturing process of circuit boards typically involves processes such as material preparation, drilling, copper plating, pattern transfer, electroplating, and etching. In the material preparation step, a large sheet of material is usually cut into smaller pieces that meet the design requirements.

[0003] The traditional production method involves manually removing the cut circuit boards one by one from the cutting machine's operating table. This method requires manpower, and there is a vacuum period when removing them manually, which cannot maximize production efficiency. At the same time, the residual heat from the cutting machine may cause burns to the workers. Utility Model Content

[0004] In order to improve the efficiency of circuit board production and protect the health of workers, this application provides an automatic circuit board cutting device.

[0005] The automatic circuit board cutting device provided in this application adopts the following technical solution:

[0006] An automatic circuit board cutting device includes a cutting table, a cutting mechanism, a first unloading assembly, and a storage platform. The cutting mechanism includes a cutting blade, a first drive cylinder, and a cutting conveyor belt. The cutting blade is slidably connected to the cutting table, and the sliding direction of the cutting blade is vertical. The first drive cylinder is connected to the cutting table and is used to drive the cutting blade to slide. The cutting conveyor belt is connected to the cutting table and is used to transport the circuit board. The transport direction of the cutting conveyor belt is perpendicular to the length direction of the cutting blade. The first unloading assembly includes a conveyor platform and an unloading conveyor belt. The conveyor platform is connected to the cutting table, and the unloading conveyor belt is connected to the conveyor platform and is used to transport the circuit board. The storage platform is located below the conveyor platform on the side away from the cutting table.

[0007] By adopting the above technical solution, the circuit board is placed on the cutting table, the first drive cylinder drives the cutting blade to slide, thereby cutting the circuit board. The cutting conveyor belt transports the cut circuit board to the conveyor table, and the unloading conveyor belt transports the cut circuit board to the top of the storage table in sequence, thereby realizing automatic unloading, improving the production efficiency of the equipment, reducing manual intervention, reducing the labor intensity of the workers, reducing the possibility of injury caused by improper manual operation, and protecting the health of the workers.

[0008] Preferably, the first feeding component further includes a second feeding assembly, which comprises a second transmission frame, a second vertical drive assembly, a second horizontal drive assembly, and a second feeding suction cup. The first feeding assembly also includes a deceleration block connected to the conveyor table. The deceleration block is used to abut against the end of the circuit board away from the cutting table. The second transmission frame is slidably connected to the conveyor table. The second vertical drive assembly is connected to the cutting table and is used to drive the second transmission frame to slide vertically. The second horizontal drive assembly is connected to the cutting table and is used to drive the second transmission frame to slide horizontally. The second feeding suction cup is connected to the second transmission frame and is used to adsorb the circuit board above the feeding conveyor belt and place it on the storage table.

[0009] By adopting the above technical solution and setting a deceleration block, the circuit board stops smoothly after contacting the deceleration block, which facilitates the second feeding component to pick up the circuit board and place it on the platform, thus helping to achieve uniform arrangement of the circuit boards.

[0010] Preferably, the first feeding assembly further includes a second drive cylinder. The conveyor is slidably connected to the cutting table, and the sliding direction of the conveyor is vertical. The second drive cylinder is connected to the cutting table and is used to drive the conveyor to slide. The deceleration block is connected to the cutting table. The conveyor is provided with a groove for the deceleration block to pass through. When the upper surface of the feeding conveyor belt is flush with the upper end of the cutting table, the upper end of the deceleration block is embedded in the groove.

[0011] By adopting the above technical solution, when the second unloading component adsorbs the previous circuit board and places it on the platform, the second drive cylinder drives the conveyor to move upward, so that the upper surface of the conveyor is flush with the upper surface of the cutting platform, making it easier for the next circuit board to fall onto the conveyor. The deceleration block is embedded in the groove, so that the next circuit board is smoothly transported to the top of the platform by the unloading conveyor belt, thereby improving the unloading efficiency.

[0012] Preferably, the cutting mechanism further includes a sliding seat, a third drive cylinder, and a fixed suction cup. The sliding seat is slidably connected to the cutting table, and the sliding direction of the sliding seat is vertical. The third drive cylinder is connected to the cutting table and is used to drive the sliding seat to slide. The upper end of the cutting table is provided with a plurality of sliding grooves, which are distributed at intervals along a direction perpendicular to the length of the cutting blade. The number of cutting conveyor belts is the same as the number of sliding grooves and corresponds one-to-one. The cutting conveyor belts are connected to the sliding seat and are slidably embedded in the sliding grooves. The fixed suction cup is connected to the upper end of the cutting table and is used to adsorb the side surface of the circuit board near the cutting table. There are a plurality of fixed suction cups, which are evenly distributed on the upper end of the cutting table.

[0013] By adopting the above technical solution, the third drive cylinder drives the sliding seat to move downward, which in turn moves the cutting conveyor belt downward, so that the cutting conveyor belt is embedded in the groove, and the fixed suction cup adsorbs the circuit board, reducing the possibility of the circuit board moving during the cutting process and improving the reliability of the equipment processing.

[0014] Preferably, the cutting mechanism further includes a connecting seat, a fixing strip, and a first resetting member. The connecting seat is slidably connected to the cutting table, and the sliding direction of the connecting seat is vertical. The cutting blade is connected to the connecting seat, and the fixing strip is slidably connected to the connecting seat, and the sliding direction of the fixing strip is vertical. When the cutting blade moves away from the cutting table, the fixing strip is located below the cutting blade. The first resetting member is connected to the connecting seat and the fixing strip, and the first resetting member causes the fixing strip to tend to move closer to the cutting table.

[0015] By adopting the above technical solution, the first drive cylinder drives the connecting seat to move downward, which in turn drives the cutting blade and the fixing strip to move downward. The fixing strip is located below the cutting blade. During the downward movement of the connecting seat, the fixing strip first abuts against the circuit board. The cutting blade continues to move downward to cut the circuit board. The fixing strip moves upward relative to the connecting seat. Under the action of the first reset member, the fixing strip presses against the circuit board, reducing the possibility of the circuit board moving during the cutting process and improving the reliability of the equipment processing.

[0016] Preferably, the assembly further includes a feeding component, a support base, and a baffle. The support base is located on the side of the cutting table away from the placement table. The baffle is connected to the side of the support base near the cutting table and is used for the end of the circuit board near the cutting table to abut against it. The feeding component includes a rotating roller, a first transmission frame, a first vertical drive component, a first horizontal drive component, and a first transmission suction cup. The rotating roller is rotatably connected to the support base, and the rotation axis of the rotating roller is horizontal. There are several rotating rollers, which are evenly distributed along a direction perpendicular to the rotation axis of the rotating roller. The first transmission frame is slidably connected to the support base. The first vertical drive component is connected to the support base and is used to drive the first transmission frame to slide in a vertical direction. The first horizontal drive component is connected to the support base and is used to drive the first transmission frame to slide along the conveying direction of the cutting conveyor belt. The first transmission suction cup is connected to the first transmission frame and is used to adsorb the circuit board above the rotating roller and place it on the cutting table.

[0017] By adopting the above technical solution, the circuit board is placed above the rotating roller, the rotating roller drives the circuit board to slide against the baffle, the first transmission suction cup adsorbs the circuit board, the first horizontal driving component and the first vertical driving component drive the first transmission frame to slide, and place the circuit board on the cutting table, realizing circuit board loading. There is no need for the staff to place the circuit board on the cutting table, which improves the safety of the equipment.

[0018] Preferably, it further includes a positioning plate and a fourth drive cylinder. The positioning plate is slidably connected to the support base. The sliding direction of the positioning plate is parallel to the rotation axis of the rotating roller. There are two positioning plates, which are symmetrically distributed along the rotation axis of the rotating roller. The number of fourth drive cylinders is the same as the number of positioning plates and corresponds one-to-one. The fourth drive cylinder is connected to the support base and is used to drive the positioning plate to slide.

[0019] By adopting the above technical solution and setting up positioning plates, the two positioning plates abut against the two sides of the circuit board, so that the circuit board is located directly below the first transfer suction cup, which facilitates the first transfer suction cup to adsorb the circuit board and improves the reliability of the equipment.

[0020] Preferably, the lower end of the positioning plate is provided with several grooves, and several rotating rollers are respectively rotatably embedded in several grooves, with the outer wall of the rotating rollers fitting against the groove wall.

[0021] By adopting the above technical solution, the lower end of the positioning plate is provided with a groove, and the outer wall of the rotating roller is in contact with the groove wall, which guides the sliding of the positioning plate and improves the stability of the sliding of the positioning plate.

[0022] Preferably, it also includes a protection mechanism, which includes two safety light curtain assemblies, and the two safety light curtain assemblies are respectively connected to both sides of the cutting table along the conveying direction of the cutting conveyor belt.

[0023] By adopting the above technical solution, the safety light curtain assembly can immediately stop the machine when it detects a human body or other obstacle entering the danger zone, effectively preventing workers from being injured due to accidental contact or contact, and ensuring the safety of workers' lives.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. Place the circuit board on the cutting table. The first drive cylinder drives the cutting blade to slide, thereby cutting the circuit board.

[0026] 2. When the second unloading component picks up the previous circuit board and places it on the platform, the second drive cylinder drives the conveyor to move up, so that the upper surface of the conveyor is flush with the upper surface of the cutting table, making it easier for the next circuit board to fall onto the conveyor. The deceleration block is embedded in the groove, so that the next circuit board is smoothly transported to the top of the platform by the unloading conveyor belt, improving unloading efficiency.
