A Corona Treatment Machine with Adaptive Distance

Abstract

This application relates to the field of corona treatment machine technology and discloses an adaptive distance corona treatment machine, including a base plate. A main body of the treatment machine is mounted on the upper surface of the base plate. Two cables are fixedly installed on the back of the main body of the treatment machine, and a corona head is fixedly installed at the other end of each cable. This adaptive distance corona treatment machine, by setting up components such as a threaded rod, a slider, a corona head, and a laser rangefinder, detects the distance between the corona head and the workpiece surface using the laser rangefinder. It then activates a corresponding motor to rotate the threaded rod, which in turn drives the slider to rise and fall, thereby raising and lowering the mounting plate and the corona head until the mounting plate moves the corona head on the bottom surface to the required height. This allows the device to adjust the distance between the corona head and the workpiece surface in real time, achieving an adaptive distance effect, thus maintaining a constant discharge gap and improving processing uniformity.

Description

Technical Field

[0001] This application relates to the field of corona treatment technology, specifically to a corona treatment machine with adaptive distance. Background Technology

[0002] Corona treatment technology is a widely used method for modifying material surfaces. It generates a corona on the material surface through high-voltage discharge, causing the surface molecules to polarize or oxidize, thereby increasing the surface energy. Currently, corona treatment machines play an important role in industries such as packaging, printing, and electronics. Especially in the treatment of plastic films, corona technology has become the mainstream choice due to its high efficiency and environmental friendliness. With the advancement of materials science, the requirements for surface treatment are becoming increasingly stringent, and corona treatment technology is constantly being optimized to meet diverse needs.

[0003] An existing patent (publication number: CN217373565U) discloses a three-dimensional curved surface corona treatment machine, including an operating table. Four fixed cylinders are fixed to the top of the operating table. A push-back assembly is installed inside each fixed cylinder. A base is inserted into the inside of each fixed cylinder. The treatment machine body is installed between the tops of the four bases. A magnetic block is fixed to the top of each base. A clamping assembly is installed on the outside of each fixed cylinder. The push-back assembly includes a first spring fixed to the bottom wall of the fixed cylinder and a push plate fixed to the top of the first spring. This three-dimensional curved surface corona treatment machine, through the cooperation between the structures in the push-back assembly and the clamping assembly, facilitates the installation and disassembly of the treatment machine body by operators. Therefore, it effectively improves the stability during placement and prevents positional displacement under collision or other external forces, while also preventing damage to the treatment machine body from drops.

[0004] However, in the above-mentioned scheme, it was found that when using a processor, cable and corona head to process three-dimensional curved surfaces, the corona head usually needs to be held by the operator or fixed at a specified height. When the operator holds the corona head, it is impossible to maintain a constant discharge gap. When it is fixed at a specified height, the discharge gap cannot be changed, resulting in an uncontrollable distance between the corona head and the workpiece surface, which easily leads to a decrease in processing uniformity. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an adaptive distance corona treatment machine, which can adjust the distance between the corona head and the workpiece surface in real time to achieve an adaptive distance effect. This allows for maintaining a constant discharge gap and improving processing uniformity. It solves the problems of existing technologies, which typically require operators to hold the corona head or fix it at a specified height. The handheld method can easily lead to the inability to maintain a constant discharge gap, while the fixed method prevents the discharge gap from being changed, resulting in uncontrollable distance between the corona head and the workpiece surface and reduced processing uniformity.

[0006] To achieve the above objectives, this application provides the following technical solution: a corona treatment machine with adaptive distance, comprising a base plate, a treatment machine body disposed on the upper surface of the base plate, two cables fixedly installed on the back of the treatment machine body, a corona head fixedly installed at the other end of each cable, two uprights fixedly installed on the upper surface of the base plate, a motor fixedly installed on the upper surface of each upright, a threaded rod fixedly connected to the output shaft of each motor, the outer surface of each threaded rod rotatably connected to the inner wall of the corresponding upright, a slider threadedly connected to the outer surface of each threaded rod, a groove formed on the side of each upright that is close to each other, the inner wall of each groove slidably connected to the outer surface of the corresponding slider, a mounting plate fixedly connected to the side of each slider that is close to each other, the bottom surface of each mounting plate fixedly connected to the upper surface of the corresponding corona head, the inner wall of each mounting plate fixedly connected to the outer surface of the corresponding cable, a mounting frame fixedly installed on the front of each mounting plate, and a laser rangefinder fixedly installed on the inner wall of each mounting frame.

[0007] The above scheme enables the device to adjust the distance between the corona head and the workpiece surface in real time, achieving an adaptive distance effect and maintaining a constant discharge gap to improve processing uniformity. By configuring the main body of the processor, cables, and the corona head, the device performs corona treatment on the workpiece surface. A mounting frame is installed on the front of the mounting plate, and a laser rangefinder is installed on the inner wall of the mounting frame. This laser rangefinder facilitates the detection of the distance between the corona head and the workpiece surface below. Then, the corresponding motor is activated, causing the corresponding threaded rod to rotate. Through the connection between the threaded rod and the slider, the slider can slide up and down on the inner wall of the groove, allowing the slider and mounting plate to rise and fall until the mounting plate moves the corona head on the bottom to the required height. This allows the device to adjust the distance between the corona head and the workpiece surface in real time, achieving an adaptive distance effect and maintaining a constant discharge gap to improve processing uniformity.

[0008] Furthermore, a second motor is fixedly installed on the right side of the base plate, and two transmission rollers are rotatably connected to the inner wall of the base plate. The output shaft of the second motor is fixedly connected to the right end of the corresponding transmission roller.

[0009] With the above scheme, motor 2 is installed on the right side of the base plate and set as a fixed connection to realize the installation of motor 2. The transmission roller is installed on the inner wall of the base plate and set as a rotatable connection to realize the limiting of the transmission roller. The output shaft of motor 2 is connected to the corresponding transmission roller so that motor 2 can drive the transmission roller to rotate.

[0010] Furthermore, a transmission belt is provided above the base plate, and the outer surface of each transmission roller is connected to the inner wall of the transmission belt.

[0011] With the above scheme, the transmission belt is set above the base plate and connected to the transmission roller. When the second motor drives one of the transmission rollers to rotate, the transmission belt can drive the workpiece on the upper surface to move through the connection between the transmission belt and the transmission roller.

[0012] Furthermore, two guide members are fixedly installed on the inner side wall of the base plate.

[0013] The above scheme allows the guide to be installed on the inner wall of the base plate. The arc-shaped surface of the guide enables the workpiece to automatically move to the area below the corresponding laser rangefinder when it is driven on the transmission belt.

[0014] Furthermore, a limiting plate is fixedly connected to the upper surface of one of the mounting plates, and the outer surface of each cable is fixedly connected to the inner wall of the limiting plate.

[0015] With the above solution, the limiting plate is installed on the upper surface of the mounting plate to fix the outer surface of the cable to the limiting plate, so that the cable can be limited and prevented from sagging.

[0016] Furthermore, a guide plate is fixedly connected to the back of one of the uprights, and a guide groove is provided on the right side of the guide plate.

[0017] The above method involves installing the guide plate on the back of one of the uprights as a fixed connection, thereby achieving the installation of the guide plate. A guide groove is opened on the right side of the guide plate, which runs through the guide plate. The cable is placed in the guide groove to prevent it from falling into the transmission belt area and thus avoiding interference with the corona treatment.

[0018] Furthermore, a limit rod is fixedly connected to the upper surface of the base plate, and a fixing plate is fixedly connected to the upper surface of the base plate.

[0019] The above method involves installing the limiting rod on the upper surface of the base plate as a fixed connection, and then installing the fixing plate on the upper surface of the base plate to achieve the installation of the fixing plate.

[0020] Furthermore, the inner wall of the fixing plate is threadedly connected to a threaded rod II, and the right end of the threaded rod II is rotatably connected to a clamping plate.

[0021] The above scheme involves installing the second threaded rod on the inner wall of the fixed plate and setting it as a threaded connection. By rotating the second threaded rod, it can be connected to the fixed plate, allowing the second threaded rod to move. The clamping plate is then connected to the second threaded rod and rotated to the right end of the second threaded rod, so that when the second threaded rod rotates, the clamping plate can clamp the main body of the processor.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This adaptive distance corona treatment machine comprises components such as a threaded rod, a slider, a corona head, and a laser rangefinder. The laser rangefinder detects the distance between the corona head and the workpiece surface, activating a corresponding motor to rotate the threaded rod. The threaded rod then drives the slider to rise and fall, thereby raising and lowering the mounting plate and the corona head until the mounting plate moves the corona head to the desired height. This allows the device to adjust the distance between the corona head and the workpiece surface in real time, achieving an adaptive distance effect. This maintains a constant discharge gap and improves processing uniformity. A limiting rod on the upper surface of the base plate limits the right side of the machine body. Rotating the threaded rod connects it to a fixed plate, causing a clamping plate to move. This movement limits the left side of the machine body, achieving a clamping and limiting effect. This prevents the machine body from shifting due to collisions or other external forces, and also prevents damage from drops. Attached Figure Description

[0038] Please see Figure 2 and Figure 3A limiting rod 20 is fixedly connected to the upper surface of the base plate 1, and a fixing plate 21 is fixedly connected to the upper surface of the base plate 1. The limiting rod 20 is installed on the upper surface of the base plate 1 to form a fixed connection, and the fixing plate 21 is installed on the upper surface of the base plate 1 to realize the installation of the fixing plate 21.

[0039] Please see Figure 1 , Figure 2 and Figure 4 The inner wall of the fixing plate 21 is threaded with a threaded rod 22. The right end of the threaded rod 22 is rotatably connected to a clamping plate 23. The threaded rod 22 is installed on the inner wall of the fixing plate 21 and is set as a threaded connection. By rotating the threaded rod 22, the threaded rod 22 can be connected to the fixing plate 21, so that the threaded rod 22 can move. The clamping plate 23 is connected to the threaded rod 22 and rotatably connected to the right end of the threaded rod 22, so that when the threaded rod 22 rotates, the clamping plate 23 can clamp the main body 9 of the processor.

[0040] This embodiment of an adaptive distance corona treatment machine includes components such as a threaded rod 4, a slider 6, a corona head 8, and a laser rangefinder 12. The laser rangefinder 12 detects the distance between the corona head 8 and the workpiece surface, activating the corresponding motor 3 to rotate the threaded rod 4. The threaded rod 4 then drives the slider 6 to rise and fall, thereby raising and lowering the mounting plate 7 and the corona head 8 until the mounting plate 7 moves the corona head 8 to the required height. This allows the device to adjust the distance between the corona head 8 and the workpiece surface in real time, achieving an adaptive distance effect. To maintain a constant discharge gap and improve processing uniformity, a limiting rod 20 is set on the upper surface of the base plate 1 to limit the right side of the processor body 9. Then, the threaded rod 22 is rotated to connect with the fixed plate 21, thereby driving the clamping plate 23 to move. Through the movement of the clamping plate 23, the left side of the processor body 9 is limited. This device can clamp and limit the processor body 9, preventing the processor body 9 from shifting its position under collision or other external forces, and also preventing damage to the processor body 9 from falling.

[0041] It should be noted that both motor 3 and motor 13 are servo motors, which can realize the forward and reverse rotation of threaded rod 4 and transmission roller 14 respectively, thereby achieving the lifting effect of slider 6 and the conveying effect of transmission belt 15. Three-dimensional curved surface corona treatment can be achieved through the main body of the processing machine 9, cable 10 and corona head 8.

[0042] The working principle of the above embodiments is as follows:

[0043] First, the main body 9 of the processing machine is placed on the base plate 1. The right side of the main body 9 is limited by the limiting rod 20. Then, the threaded rod 22 is rotated to connect with the fixed plate 21, thereby driving the clamping plate 23 to move. The movement of the clamping plate 23 limits the left side of the main body 9, preventing the main body 9 from shifting its position under collision or other external forces, and also preventing damage to the main body 9 from falling. Then, the motor 13 is started to rotate the transmission roller 14, thereby enabling the transmission belt 15 to drive the transmission. The workpiece is placed on the surface of the transmission belt 15. The workpiece is conveyed by guide 16 to the area below the corresponding laser rangefinder 12. The laser rangefinder 12 detects the distance between the corona head 8 and the workpiece surface. Then, the corresponding motor 3 is started to rotate the corresponding threaded rod 4. The threaded rod 4 drives the slider 6 to rise and fall inside the slide groove 5, thereby allowing the mounting plate 7 and the corona head 8 to rise and fall until the mounting plate 7 moves the corona head 8 on the bottom surface to the required height. This allows the device to adjust the distance between the corona head 8 and the workpiece surface in real time, achieving an adaptive distance effect, thus maintaining a constant discharge gap and improving processing uniformity.
