Description

Technical Field

[0001] This invention relates to the field of screw-making technology, specifically to an intelligent positioning screw-making machine. Background Technology

[0002] A screw tightening machine is an automated device used to replace traditional manual screw tightening. It automatically completes screw feeding, positioning and fastening operations to improve efficiency. It is widely used in fields such as electronic products, home appliances and machinery manufacturing. Screw tightening machines have advantages such as high working efficiency and good product consistency, and can meet the requirements of modern industrial automation for assembly efficiency and assembly precision.

[0003] During the fastening process of existing screw fastening machines, screws are prone to contact with impurities such as metal shavings and dust in the workpiece and feeding track during the conveying process. This causes the threads and screw heads to be covered with debris, which affects the contact stability between the screw head and the bit, leading to problems such as slippage and jamming. At the same time, the debris on the threaded part can affect the meshing with the workpiece, resulting in stripped threads and damage. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of screws adhering to impurities during transportation in the prior art, and to propose an intelligent positioning screw machine.

[0005] To solve the above problems, the present invention provides the following technical solution: A smart positioning screw machine includes a worktable, a lifting device is installed on the worktable, a first driving component is installed on one side of the lifting device, a screw-locking device is installed on the first driving component, and a flipping device is installed on one side of the screw-locking device. The first driving component is connected to a control system. The first driving component includes a first motor and a linear guide rail. The first motor drives the linear guide rail to move. The linear guide rail is installed on an electric screwdriver. During operation, the workpiece is manually placed on the flipping device, the flipping device is controlled to move below the screw-locking device, the lifting device is controlled to lower the screw-locking device to the threaded hole of the workpiece, and the screw-locking device is controlled to lock the screw into the threaded hole of the workpiece.

[0006] The screw-locking device includes a housing and a guide cylinder. A screw channel is installed on the housing, and an electric screwdriver is slidably installed inside the housing. A first driving component is installed on the electric screwdriver, and a sealing component is installed on one side of the electric screwdriver. The electric screwdriver is connected to the control system. In use, the feeding mechanism blows the screw into the screw channel, and the screw falls into the guide cylinder through the screw channel. The guide cylinder positions and aligns the screw, and at the same time cleans the screw head and threads, blowing the cleaned debris out of the housing. The electric screwdriver is then controlled to lock the screw into the threaded hole of the workpiece.

[0007] The guide cylinder includes a cylinder body installed inside a housing. A positioning element is installed inside the cylinder body, and a trigger element is installed on one side of the positioning element. The trigger element slides within the housing. A cleaning element is installed on one side of the cylinder body, and the cleaning element is connected to the sealing assembly via a pipe. The positioning element is used to position the centering screw, the cleaning element is used to clean debris adhering to the screw threads and screw head, and the trigger element is used to control the activation of the positioning element.

[0008] The sealing assembly includes a sealing slider that slides within a housing. An air supply element is mounted on one side of the sealing slider and is installed on a lifting device. An air supply pipe is installed on the air supply element. The air supply element is activated via the air supply pipe and supplies air to the cleaning element. The sealing slider maintains the airflow in the area where the cleaning element is located.

[0009] The positioning element includes an arc-shaped plate with a guide post mounted on it. The guide post slides within the cylinder. A first elastic element is sleeved on the outer side of the guide post. One end of the first elastic element is mounted on the cylinder, and the other end is mounted on the arc-shaped plate. A support plate is mounted on one side of the arc-shaped plate, a first wedge block is mounted on one end of the arc-shaped plate, and a guide plate is mounted on the other end. The first elastic element is a first spring. When the screw falls into the cylinder, it first falls onto the support plate. The trigger element moves away from the first wedge block, and the first spring stretches, causing the arc-shaped plate to move towards the axis of the cylinder until the arc-shaped plate abuts against the screw head, aligning the screw head.

[0010] The cleaning element includes an air jet ring mounted on one side of the cylinder. A spiral nozzle is installed inside the air jet ring, and an air vent is mounted on the air jet ring, connecting to the spiral nozzle. An air jet port is installed inside the housing, and a chip discharge port is installed on one side of the air jet port. Part of the airflow enters the spiral nozzle through the air vent and is ejected through the spiral nozzle, forming an upward spiral airflow that blows away debris adhering to the screw's threaded portion. Another part of the airflow exits from the air jet port, blowing away debris from the screw head's groove. Both parts of the debris are discharged together through the chip discharge port.

[0011] The triggering element includes a limiting plate, which is installed on the inner wall of the housing. A damping pad is installed on the limiting plate. A second elastic element is installed on one side of the damping pad. A sliding ring is installed on one side of the second elastic element. The sliding ring slides inside the housing. A connecting rod is installed on one side of the sliding ring. A second wedge block is installed on one side of the connecting rod. The second elastic element is a second spring. Initially, the second wedge block presses against the first wedge block, pulling the arc plate apart by a certain distance to facilitate the screw head falling onto the support plate. When the screw head falls onto the support plate, the sealing cover moves towards the electric screwdriver. The sealing cover drives the sliding ring to move towards the electric screwdriver, and the sliding ring drives the connecting rod to move towards the electric screwdriver. The connecting rod drives the second wedge block to move towards the electric screwdriver until the second wedge block leaves the first wedge block. When the electric screwdriver descends, the shell of the electric screwdriver presses against the sliding ring. The electric screwdriver drives the sliding ring to move away from the electric screwdriver, and the sliding ring drives the connecting rod to move away from the electric screwdriver. The connecting rod drives the second wedge block to move away from the electric screwdriver. The second wedge block presses against the first wedge block, and the first wedge block moves away from the axis of the cylinder until the arc plate leaves the screw head, facilitating the head of the electric screwdriver to move the screw onto the workpiece.

[0012] The sealing slider includes a sealing cover that slides within a housing. A sliding groove is provided within the housing. An extension rod is mounted on the sealing cover, and a sealing plate is mounted on the extension rod. The sealing plate slides within the sliding groove. A connecting plate is mounted at one end of the extension rod. The connecting plate drives the extension rod to move, and the extension rod causes the sealing cover to slide within the housing.

[0013] The air supply element includes a piston housing mounted on a lifting device. A baffle is installed inside the piston housing, and a first piston rod is mounted on one side of the baffle. The first piston rod slides within the piston housing. A connecting post is mounted on the first piston rod, and a second piston rod is mounted on the connecting post. The second piston rod is located on the other side of the baffle. One end of a connecting plate is mounted on the connecting post. A third elastic element, a third spring, is installed between the first piston rod and the baffle. The piston housing is mounted on a fixed plate. The feeding mechanism distributes the airflow from the screw-blowing pipe into the air inlet pipe. The air inlet pipe causes the first piston rod to move away from the fixed plate. The first piston rod then causes the connecting post to move away from the fixed plate. The connecting post then causes the second piston rod to move away from the fixed plate. The connecting post then causes the connecting plate to move away from the fixed plate. When the screw is blown into the cylinder, the third spring stretches, causing the first piston rod to return to its original position.

[0014] The ventilation duct includes an inlet pipe mounted on the piston housing. A first jet pipe, an exhaust pipe, and a second jet pipe are sequentially installed on one side of the inlet pipe. The first jet pipe is connected to the ventilation pipe via a pipe. A dust collection bag is installed at one end of the exhaust pipe and is mounted on the chip discharge port. The second jet pipe is connected to the air outlet via a pipe. A pressure relief pipe is installed on one side of the first jet pipe. When the first piston rod moves away from the fixed plate, the first jet pipe discharges gas into the ventilation pipe, and the second jet pipe discharges gas into the air outlet. The exhaust pipe creates a negative pressure suction, drawing debris from the chip discharge port into the dust collection bag.

[0015] The lifting device includes a guide rod, a mounting plate mounted on one side of the guide rod, a second drive component mounted on one side of the mounting plate, a lead screw mounted on one side of the second drive component, a lifting plate slidably mounted on the lead screw, and a fixing plate mounted on the guide rod. The second drive component is connected to a control system. The second drive component is a second motor, which drives the lead screw to rotate, causing the lead screw to move the mounting plate on the lead screw. The mounting plate then drives the first motor and the screw-locking device to move.

[0016] The flipping device includes a slide rail, on which a U-shaped plate is slidably mounted. A third driving component is mounted on one side of the U-shaped plate, and a fourth driving component is mounted on the U-shaped plate. A flipping plate is mounted on the fourth driving component. The third and fourth driving components are connected to a control system. The third driving component is a third motor, and the fourth driving component is a fourth motor. The third motor drives the U-shaped plate to move below the screw-locking device. After the screws on one side of the workpiece are tightened, the fourth motor is controlled to drive the flipping plate to rotate, causing the other side of the workpiece to align with the screw-locking device.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: the dual cleaning device can simultaneously clean the debris attached to the threads and screw head surface before fastening. The nozzle blows the screw head to remove the debris in the screw head groove. The spiral nozzle at the screw creates an upward rotating airflow, which not only prevents the blown-down debris from falling onto the workpiece, but also blows away the debris adhering to the threads. The debris from the threads and screw head is transported together to the dust collection bag, which not only improves the stability of the fit between the bit and the screw head, but also allows the threads to accurately enter the workpiece, thus improving the quality of the finished product.
