Description

Technical Field

[0001] The invention relates to the technical field of notebook marking, in particular to a notebook shell auxiliary positioning laser marking device. Background Art

[0002] In order to ensure accurate positioning and consistency in the marking process on the laptop shell, laser marking technology is widely used in electronics, automotive parts, aerospace and other industries. It can provide precise markings such as serial numbers, company logos, QR codes, etc. The notebook shell auxiliary positioning laser marking device not only ensures accuracy, but also improves production efficiency. It is one of the indispensable equipment in modern manufacturing.

[0003] The patent with announcement number CN215545852U discloses a marking machine for processing laptop computer shells, including a marking machine, a chassis and a blanking plate. The marking machine is fixedly connected to the right side of the rear side of the top of the chassis, and the right side of the blanking plate is fixedly connected to the top of the left side of the chassis. This patent sets a pushing component, which can drive the pushing component through the transmission mechanism to move the baffle to the left, and push the marked material to the blanking plate. At the same time, the heat dissipation holes and the heat dissipation fan can discharge the heat inside the body, which can prevent the internal temperature of the chassis or the marking machine from being too high, causing the wire to melt and cause a short circuit in the equipment. It solves the problem that the existing notebook laser marking machine needs to be manually aligned and positioned, then fixed, and then marked. When the marking is completed, the fixed notebook shell is taken out, and the next round of marking operation is cumbersome, and the manual speed is slow, which affects the marking efficiency. It has the advantages of automatic loading and unloading, but this patent still has the problem that dust adheres to the laser lens, which is easy to cause wear and tear and requires regular maintenance.

The blocking plate is fixedly connected to the air blowing pipe. The air blowing pipe is unidirectionally connected from the inside of the air suction groove pipe to the outside of the air suction groove pipe. The built-in motor of the flip arm drives the flip arm to rotate around the base, so that the flip arm flips and applies pressure downward to the pressure rod. After the pressure rod is subjected to force, it pushes the connected connecting rod seat to move. The connecting rod seat makes the lifting plate move downward along the vertical sliding rod, so that the laser lens connected to the bottom side of the lifting plate is close to the parts that need to be marked below. In this process, the lifting plate moves downward to drive the connected pressing rod to move downward. The cylinder pushes the piston at the bottom to slide along the inner wall of the air cavity, and the air in the air cavity is discharged through the air pipe connected to the piston. At this time, the air pipe moves with the lower pressure cylinder and slides with the air cavity. The air discharged through the air pipe is transported to the connected suction groove pipe, so that the air blows the blocking piece to bend downward and form a gap with the inner wall of the blowing pipe, and the air is discharged from the blowing pipe through the gap. In addition, the oil tank built into the vertical guide block is discharged into the lower pressure cylinder through the connected oil pipe. The oil is discharged into the lower pressure cylinder through the downward movement of the lower pressure cylinder, so that the lower pressure cylinder is close to the upper ejector rod, and the upper ejector rod squeezes the space in the lower pressure cylinder to release the lubricating fluid through the one-way leaf The one-way leaf disc is discharged, so that the lubricating liquid is reserved above the one-way leaf disc and in the connected oil drain pipe. When the lubricating liquid in the oil drain pipe accumulates to a certain amount, it can lubricate the rotating shaft of the flip arm, thereby reducing the wear of parts and improving the service life of parts. At the same time, when the pressure cylinder moves upward again, the pressure cylinder drives the piston to draw the outside air into the air cavity. The outside air absorbs the dust attached to the laser lens through the air suction groove tube, and allows the dust to pass through the dust collecting cone cylinder in the air suction groove tube along with the air, and use the air to push open the elastic cover sheet on the dust collecting cone cylinder, and allow the air to enter the air cavity through the connected air supply pipe.

When the flip arm flips around the table seat, the bottom end of the flip arm applies pressure to the elastic frame, so that the elastic frame pulls the pull-down folding plate downward through the tension spring, and the movement of the elastic frame drives the connected cross frame and the inclined slot plate to move downward, so that the inclined slot plate and the upper slot plate pass downward. During the process, pressure is applied to the bent slide bar, so that the bent slide bar pulls the connected hinged connecting rod along the guide plate. In this process, the upper slot plate first slides along the horizontal frame through the connected vertical slide plate to squeeze the reset spring. When the reset spring shrinks under pressure, the spring elastic force provides support for the vertical slide plate, so that the vertical slide plate pulls the bent slide bar to slide along the guide plate through the connected upper slot plate. The guide plate pulls the hinged connecting rod, so that the pull rod connected to the hinged connecting rod pulls the connecting rod cross plate to slide along the fixed bar, and uses the fixed bar to push the telescopic push plate connected to the spring sheet, so that the two telescopic push plates are close to each other to push the accessories on the conveyor belt to the center.

[0012] According to the above technical solution, the positioning and buffering mechanism includes a pressure plate, and two slide groove bars are arranged above the pressure plate. The top surface of each slide groove bar is fixedly connected to a pressure rubber strip, and the front end surface of the slide groove bar is fixedly connected to a bent connecting rod.

As the pressure plate falls, the pressure strip moves to apply pressure to the edge of the accessory. At this time, the elastic frame continues to move downward to pull the tension spring to deform, and the pull-down folding plate stops moving. The width of the accessory is measured by the telescopic push plate to assist in adjusting the position of the pressure strip. At the same time, when the pressure plate is reset upward, the pressure plate pulls the connecting cable to drive the flip handle to flip around the connection of the discharge chute, and the buffer flap is driven to rise through the flip handle, and the potential energy generated by the accessory sliding down the discharge chute is consumed through the buffer flap.

The fixed bar is used to push the telescopic push plate connected to the spring sheet, so that the two telescopic push plates are close to each other to push the accessories on the conveyor belt to the center. When the telescopic push plate contacts the accessories, the spring sheet is squeezed to deform, so that the telescopic push plate is prevented from continuously pushing the accessories to cause the accessories to be compressed and deformed. By adjusting the placement position of the accessories on the conveyor belt, the placement position is prevented from affecting the position of the laser marking, so as to prevent affecting the effect of the laser marking.

After the pressure rod 53 is subjected to force, it pushes the connected connecting rod seat 54 to move. The connecting rod seat 54 makes the lifting plate 55 move downward along the vertical slide rod 58, so that the laser lens 56 connected to the bottom side of the lifting plate 55 is close to the parts to be marked below. In this process, the lifting plate 55 moves downward and drives the connected downward pressure cylinder 59 to push the bottom piston to slide along the inner wall of the air cavity 510, so that the air in the air cavity 510 passes through The air pipe 514 connected to the piston is discharged. At this time, the air pipe 514 moves with the lower pressure cylinder 59 and slides with the air cavity 510. The air discharged through the air pipe 514 is transported into the connected suction groove pipe 511, so that the air blows the blocking piece 519 to bend downward and form a gap with the inner wall of the blowing pipe 520, and the air is discharged from the blowing pipe 520 through the gap. The dust attached to the parts at the marking location is blown off by the discharged air to prevent the dust from attaching and affecting the clarity of the marking. In addition, the oil tank built into the vertical guide block 57 is connected to the oil pipe 511 through the connected oil pipe 51 5 is discharged into the lower pressure cylinder 59, and the lower pressure cylinder 59 moves downward, so that the lower pressure cylinder 59 is close to the upper push rod 512, and the upper push rod 512 squeezes the space in the lower pressure cylinder 59 to discharge the lubricating liquid through the one-way leaf 513, so that the lubricating liquid is reserved above the one-way leaf 513 and in the connected oil discharge pipe 516. When the lubricating liquid in the oil discharge pipe 516 accumulates to a certain amount, it can lubricate the rotating shaft of the flip arm 52, thereby reducing the wear of parts and improving the service life of parts. At the same time, when the lower pressure cylinder 59 moves upward again, the lower pressure cylinder 59 drives the piston The outside air is drawn into the air cavity 510, and the outside air absorbs the dust attached to the laser lens 56 through the air suction groove pipe 511, and the dust is allowed to pass through the dust collecting cone 517 in the air suction groove pipe 511 along with the air, and the elastic cover sheet 518 on the dust collecting cone 517 is pushed open by the air, and the air is allowed to enter the air cavity 510 through the connected air delivery pipe 514, so as to prevent scratches caused by regular wiping of the lens, and to avoid dust attached to the lens without timely cleaning, which may cause damage to the lens, increase the maintenance cost of the equipment or shorten the service life of the lens; When the flip arm 52 flips around the pedestal 51, the bottom end of the flip arm 52 applies pressure to the elastic frame 62, so that the elastic frame 62 pulls the pull-down folding plate 61 downward through the tension spring, and the movement of the elastic frame 62 drives the connected cross frame 63 and the inclined slot plate 64 to move downward, so that the inclined slot plate 64 and the upper slot plate 65 apply pressure to the bending slide bar 67 during the downward process, so that the bending slide bar 67 pulls the connected hinged connecting rod 69 along the guide plate 68. In this process, the upper slot plate 65 first slides along the cross frame 63 through the connected vertical slide plate 66 to squeeze the return spring to be stressed. When the return spring is compressed and contracted, the spring elastic force provides support for the vertical slide plate 66, allowing the vertical slide plate 66 to pass through the connected The upper groove plate 65 pulls the bent slide bar 67 to slide along the guide plate 68, and the guide plate 68 pulls the hinged connecting rod 69, so that the pull rod 610 connected to the hinged connecting rod 69 pulls the connecting rod cross plate 612 to slide along the fixed strip 611, and the fixed strip 611 is used to push the telescopic push plate 613 connected to the spring sheet, so that the two telescopic push plates 613 are close to each other to push the accessories on the conveyor belt 4 to the center, and when the telescopic push plate 613 contacts the accessories, the spring sheet is squeezed and deformed to prevent the telescopic push plate 613 from continuously pushing the accessories to cause the accessories to be compressed and deformed. By adjusting the placement position of the accessories on the conveyor belt 4, it is prevented that the placement position affects the position of the laser marking, and prevents the effect of the laser marking from being affected; The flip arm 52 flips and pushes the elastic frame 62 to pull the tension spring to drive the pull-down folding plate 61 to slide downward along the platform 3. The movement of the pull-down folding plate 61 will drive the connected pressure plate 71 to slide downward along the vertical slide rod 58. The pressure plate 71 drives the pressure rubber strip 73 downward together through the connected slide groove bar 72. The movement of the telescopic push plate 613 drives the connected bending connecting rod 74, so that the bending connecting rod 74 drives the slide groove bar 72 to slide along the horizontal slide groove on the pressure plate 71. The slide groove bar 72 slides and mobilizes the connected pressure rubber strip 73 to move to adapt to the width of the accessory. As the pressure plate 71 falls, the pressure rubber strip 73 is moved to press on the edge of the accessory. At this time, the elastic frame 62 continues to move downward to pull the tension spring to deform , and the pull-down folding plate 61 stops moving, and the width of the accessory is measured by retracting the push plate 613 to assist in adjusting the position of the pressure strip 73. The pressure strip 73 is pressed against the edge of the accessory by position adjustment to prevent the pressure strip 73 from blocking the marking position and preventing the accessory from shifting during laser marking. At the same time, when the pressure plate 71 is reset upward, the pressure plate 71 pulls the connecting cable 75, so that the connecting cable 75 drives the flip handle 77 to flip around the connection with the discharge chute 76, and the buffer flap 78 is driven to tilt up by the flip handle 77. The buffer flap 78 is used to consume the potential energy generated by the accessory sliding down the discharge chute 76, thereby preventing the accessory from sliding down the discharge chute 76 and causing collision, which can buffer the accessory from sliding and avoiding collision.
