Description

Technical Field

[0001] This utility model relates to the field of LED production technology, and in particular to a punching device for fixing the base plate of LED production PCB. Background Technology

[0002] LED production places increasingly higher demands on PCBs. PCB mounting plates typically require a series of processing steps, especially in terms of the precision required for PCB surface treatment and hole processing. Punching is a key processing step, mainly used to drill holes in the PCB for subsequent assembly and soldering. Mounting plate punching equipment is specifically designed for this purpose. Existing equipment often needs to be adjusted under different production conditions, resulting in poor flexibility and adaptability, leading to longer downtime during production and limiting production efficiency.

[0003] The present invention discloses a punching device for fixing PCBs in LED production, as disclosed in publication number CN113263544B. The purpose of this invention is to provide a punching device for fixing PCBs in LED production that can automatically clamp and has high working efficiency. The technical solution is as follows: A punching device for fixing PCBs in LED production includes support feet and a placement plate, with four support feet at the bottom of the placement plate; baffles symmetrically arranged on the placement plate; a first fixing rod on the placement plate; a spiral spring on the first fixing rod; a feeding plate on the spiral spring, which rotates inside the placement plate; a punching mechanism on the baffle; and a clamping mechanism on the placement plate. This invention, through the cooperation between the clamping mechanism and the punching mechanism, can prevent the PCB fixing plate from shifting position during punching, thus avoiding punching failure.

[0004] However, this LED production PCB fixed base plate punching equipment has the following disadvantages: the feeding system design is not precise enough, resulting in unstable PCB board feeding, requiring manual intervention and adjustment.

[0007] As a further embodiment of this utility model, a connecting member is fixedly connected to one end of the cylinder, and a connecting shaft is rotatably connected to the middle of the connecting member. A transmission member is sleeved on the surface of the connecting shaft. By setting the connecting shaft, the connecting member can be flexibly rotated around the shaft through the rotational characteristics of the connecting shaft, thus ensuring a smoother transmission direction of the cylinder driving force.

[0008] As a further embodiment of this utility model, a motor is fixedly connected to the other side of the induced draft fan. A protective shell is fitted onto the surface of the motor. The protective shell serves to prevent external dust and debris from entering the motor, thus avoiding damage and short circuits and protecting the normal operation of the motor.

[0009] As a further embodiment of this utility model, multiple sets of dust collection hoods are fixedly connected to one side of the dust collection pipe, and a clean air pipe is fixedly connected to the top of the cyclone separator. The dust collection hoods are connected to the induced draft fan through the dust collection pipe, and the induced draft fan generates a strong airflow. This airflow carries the waste residue and dust inside the working box, which enters the internal channel of the dust collection pipe through the dust collection hoods, and is then sucked into the cyclone separator, and finally reaches the dust collection box.

[0010] As a further embodiment of this utility model, a bracket is fixedly connected to the surface of the cyclone separator, and a dust collection box is fixedly connected to the bottom of the cyclone separator. The dust collection box serves to collect the waste residue and dust sucked into the cyclone separator and ultimately fall into the dust collection box, thereby achieving centralized collection and storage of dust and facilitating subsequent unified cleaning.

[0011] As a further embodiment of this utility model, two sets of mounting brackets are fixedly connected to the surface of the workbench. A threaded rod is rotatably connected to one side of the mounting bracket. The threaded rod is used to drive the drive box to control the forward and reverse rotation of the threaded rod, thereby changing the position of the slide plate and effectively adjusting the position of the punching structure.

[0012] As a further embodiment of this utility model, a drive box is fixedly connected to one end of the threaded rod, and a sliding shaft is fixedly connected to the other side of the mounting bracket. The drive box is fixed to one end of the threaded rod to provide driving force for the rotation of the threaded rod.

[0013] As a further embodiment of this utility model, a sliding plate is sleeved on the surface of the sliding shaft, and a punching structure is fixedly connected to one side of the sliding plate. Through the setting of the sliding plate, it serves as a load-bearing and linkage component of the punching structure. The sliding plate will achieve stable position movement under the driving force of the threaded rod and the guiding action of the sliding shaft, thereby adjusting the working position of the punching structure.

[0014] (III) Beneficial Effects This utility model provides a punching device for fixing the base plate of LED production PCB, which has the following beneficial effects: 1. This LED production PCB fixed base plate punching device, through the setting of the feeding component, when it is necessary to improve the stability of PCB board feeding, the PCB is placed in the slot on the surface of the feeding plate, the cylinder is activated, and through the extension and retraction of the cylinder piston rod, the connecting piece is pushed and pulled back and forth, driving the connecting piece to push the transmission component to move, thereby driving the feeding plate to slide smoothly. The slider is fixedly connected to the bottom of the feeding plate, serving as the moving carrier of the feeding plate. Its bottom cooperates with the slide rail, and can slide stably along the slide rail axis, ensuring that the feeding plate can move smoothly back and forth along the slide rail axis. The slide rail ensures that the entire feeding structure does not deviate during the movement, making the feeding component smoother and more stable, thereby effectively improving the stability of PCB board feeding, ensuring feeding accuracy, accurately controlling the feeding speed and position, avoiding the fluctuations of manual operation, making the production process more stable and reliable, thereby improving work efficiency and extending the service life of the equipment.

[0015] 2. This LED production PCB fixed base plate punching device, through the setting of dust removal components, when it is necessary to clean the waste residue and dust removed by punching inside the working box, the motor is started, driving the induced draft fan to run. The induced draft fan will generate negative pressure, forming a directional airflow through the pipeline. This airflow will suck up the waste residue and dust inside the working box, and enter the dust collection pipe through the dust suction hood. The waste residue and dust removed by punching are introduced into the cyclone separator with the airflow, and will rotate at high speed along the wall of the separator. Due to the density difference between dust particles and air, under the action of centrifugal force, the heavier waste will be thrown to the inner wall of the separator, and then settle to the dust collection box at the bottom under the action of gravity. The purified air is discharged from the exhaust port at the top of the cyclone separator, realizing gas-solid separation. This effectively removes waste residue and dust inside the working box, ensuring a cleaner working environment, reducing equipment maintenance costs, extending equipment life, reducing downtime, ensuring the quality and safety of LED products, and improving production efficiency.

[0027] In this invention, the working steps of the device are as follows: First step: When it is necessary to improve the stability of PCB board feeding, the PCB is placed in the slot on the surface of the feeding plate 303. The cylinder 304 is activated.

This airflow will suck away the waste residue and dust inside the working box body 1 and enter the internal channel of the dust collection pipe 502 through the dust suction hood 11. This will cause the waste residue and dust removed by punching to be introduced into the cyclone separator 503 with the airflow. They will rotate at high speed along the wall of the separator. Due to the density difference between dust particles and air; The third step: Under the action of centrifugal force, the heavier waste material will be thrown against the inner wall of the separator, and then sink to the dust collection box 14 at the bottom under the action of gravity, while the purified air will be discharged from the exhaust port at the top of the cyclone separator 503, thus realizing gas-solid separation.
