Description

Technical Field

[0001] The present invention relates to the technical field of screen production, and in particular to a roller pressure adjustment system and a control method. Background Art

[0002] At present, in the well-known television (TV) production line, screen pressurization is a crucial production step. Common screen pressurization methods mainly include manual roller pressurization and electric cylinder pressurization.

[0003] Manual roller pressure is a relatively traditional method. In actual operation, it is difficult for workers to ensure that the roller applies pressure at the same location each time because it is completely dependent on manual operation. There are also big problems with the consistency of pressure. Different workers have different strengths. The single-sided pressure method will cause the screen to be stressed in one direction. Under this uneven stress condition, deformation is likely to occur, affecting the overall quality and performance of the product and increasing the defective rate of the product.

[0004] The electric cylinder pressurization method overcomes the problem of inaccurate manual operation, but the electric cylinder pressurization equipment is often designed and manufactured based on specific size specifications. When faced with TV screens of different sizes, the electric cylinder pressurization equipment cannot adapt well to screens of various sizes, resulting in the inability to achieve the ideal pressurization effect when performing pressurization operations on non-standard screens. The investment cost of the electric cylinder pressurization equipment is high. Once the production line needs to adjust the product or replace the screen of a different size for production, it is difficult for the electric cylinder pressurization equipment to make corresponding changes and adjustments quickly.

DETAILED DESCRIPTION

[0064] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0065] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0066] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0067] A roller pressure automatic adjustment system, such as Figure 1 , Figure 2 , Figure 3 As shown, including,

[0068] A roller pressurizing robot 1 and a pressurizing mechanism 2 arranged at the end of the roller pressurizing robot 1, wherein the pressurizing mechanism 2 comprises:

[0069] The mounting frame 21 is connected to the end of the roller pressurizing robot 1;

[0070] The image collector 22 is disposed on the mounting frame 21 and is used to collect the position data of the target object 4 and perform data processing to output the target positioning data;

[0071] The upper roller pressure component 23 is disposed on a side of the mounting frame 21 away from the image collector 22 and is used to pressurize the upper surface of the target object 4 under the action of a pressure control signal;

[0072] The lower roller pressure component 24 is disposed on a side of the mounting frame 21 close to the image collector 22 and is used to pressurize the lower surface of the target object 4 under the action of a pressure control signal;

[0073] The control module 3 is connected to the pressurizing mechanism 2 and is used for receiving the target positioning data and outputting a pressurizing control signal according to the target positioning data.

[0074] Specifically, the present invention provides an automatic roller pressure adjustment system for pressurizing the screen on the production line. The target object 4 refers to the screen on the production line. The image collector 22 is used to collect the position data of the target object 4, which is transmitted to the control module 3 after processing. The control module 3 outputs a pressure control signal to the upper roller pressure component 23 and the lower roller pressure component 24, which can ensure the consistency of the pressure position and pressure. The upper roller pressure component 23 and the lower roller pressure component 24 work together, and the forces offset each other to avoid deformation during the pressurization process. The pressure position can be adjusted according to the size of different screens, with high compatibility and low investment cost.

[0075] In a preferred embodiment, referring to Figure 3 The upper roller pressure assembly 23 includes:

[0076] An upper roller mounting plate 231, one end of which is connected to the mounting frame 21;

[0077] The upper roller 232 is provided at the other end of the upper roller mounting plate 231 and is used to apply pressure to the upper surface of the target object 4;

[0078] The force sensor 233 is disposed between the upper roller mounting plate 231 and the mounting frame 21 and is used to collect the pressure applied by the upper roller 232;

[0079] The electric cylinder 234 is disposed above the force sensor 233 and is used to control the upper roller 232 to move up and down, and adjust the height of the upper roller 232 to adapt to different machine sizes. The force sensor 233 and the electric cylinder 234 are not automatically adjusted in real time at the same time;

[0080] The electric cylinder 234 can automatically adjust the roller height and roller pressure to ensure constant pressure, and is compatible with different machine sizes, greatly reducing investment and later debugging and maintenance costs, and improving production flexibility and efficiency;

[0081] The lower roller pressure assembly 24 includes:

[0082] A lower roller mounting plate 241, one end of the lower roller mounting plate 241 is connected to the mounting frame 21, and the other end of the lower roller mounting plate 241 extends toward one side of the upper roller mounting plate 231 to form a bottom support plate 245;

[0083] The lower roller 242 is disposed on the bottom support plate 245 and corresponds to the position of the upper roller 232;

[0084] The cylinder 243 is disposed on the first end of the lower roller mounting plate 241. The cylinder 243 is a gas-driven linear reciprocating actuator and is connected to the lower roller 242.

[0085] A proportional valve 244 is close to the image collector 22 and is connected to the cylinder 243 to control the air flow of the cylinder 243. The proportional valve 244 can accurately control the air flow and has a fast response speed, thereby controlling the pressure of the lower roller 242;

[0086] The cylinder 243 cooperates with the proportional valve 244 to provide pressure and constant force to the lower roller 242 to adapt to the position change of the roller assembly.

[0087] Specifically, the image collector 22 is used for visual positioning of the target object 4. The image collector 22 feeds back data to the control module 3. The control module 3 processes the feedback data using a visual algorithm and then sends out a control signal. The upper roller pressure component 23 and the lower roller pressure component 24 adjust the position and pressure under the action of the control signal to solve the inaccurate position caused by the differences between each component and each tooling board. The position of each rolling is maintained at the set optimal position to ensure the quality of the product.

[0088] The cooperation between the upper and lower rollers can eliminate the problem of component deformation caused by uneven pressure on one side.

[0089] The electric cylinder 234 collects and processes data in real time, controls the pressure of the upper roller 232 to be constant, so that the pressure on the parts is constant. It can move up and down to automatically adjust the height of the roller group while keeping the force unchanged, avoiding damage to parts caused by excessive pressure and quality problems caused by insufficient pressure.

[0090] The upper roller 232 provides constant pressure on the TV screen during the rolling process to make the screen fit with the tape, and the lower roller 242 provides bottom support. During the pressurization process of the upper roller 232, the lower roller 242 provides a reaction force of the same size and opposite direction, so that the component can offset the force when it is subjected to the pressure of the upper roller 232, thereby avoiding deformation of the component.

[0091] The upper roller mounting plate 231 is used to provide a stable structural support to ensure that the upper roller 232 maintains a stable position and posture during the pressurization process, which helps to accurately apply pressure.

[0092] The upper roller 232 is connected to the mounting frame 21 so that the upper roller 232 can move to a suitable pressing position along with the mounting frame 21 under the control of the roller pressing robot 1 .

[0093] The upper roller 232 directly contacts the upper surface of the target object 4 to implement a pressurizing operation on the upper surface of the screen, and is a key component for transmitting pressure to the screen.

[0094] By cooperating with the lower roller 242, uniform pressure is applied to the screen to prevent the screen from being deformed due to unidirectional force.

[0095] The force sensor 233 collects the pressure data of the upper roller 232 in real time and provides feedback information for accurate pressure control. By monitoring the pressure, abnormal pressure conditions can be discovered in time to ensure the stability and consistency of the pressurization process.

[0096] Help the system achieve closed-loop control of pressure, so that the actual pressure can more accurately follow the preset pressure value, improving the stability of product quality.

[0097] The electric cylinder 234 can automatically adjust the height of the upper roller 232 to meet the pressure requirements of screens of different models and sizes. On the production line, the thickness and size of screens of different models may be different. The electric cylinder 234 can quickly and accurately adjust the position of the upper roller 232 to ensure the accuracy of the pressure position.

[0098] It helps to improve the production flexibility of the system, reduce the equipment adjustment time required for product switching, and improve production efficiency.

[0099] The lower roller mounting plate 241 provides a mounting base for the lower roller 242 , ensuring the stability of the lower roller 242 during operation, so that the lower roller 242 can accurately cooperate with the upper roller 232 to apply uniform pressure to the screen.

[0100] The bottom support plate 245 structure formed by its extension increases the contact area with the lower roller 242. The extension direction of the bottom support plate 245 is parallel to the bottom surface of the upper roller mounting plate 231, which helps to better withstand the force generated by the lower roller 242 when pressurized.

[0101] The cylinder 243 works on the principle of gas compressibility and pressure transmission. When compressed air enters the cavity of the cylinder 243, it pushes the piston to move, and the piston is connected to the lower roller mounting plate 241, thereby transmitting the pressure to the lower roller 242. By controlling the gas flow and pressure entering the cylinder 243 (adjusted by the proportional valve 244), the movement speed and thrust of the piston can be accurately controlled, thereby achieving accurate control of the pressure of the lower roller 242.

[0102] The proportional valve 244 can accurately control the air flow of the cylinder 243, thereby realizing high-precision control of the pressure of the lower roller 242. The pressure of the lower roller 242 can be adjusted quickly and accurately according to different production process requirements and screen characteristics.

[0103] The response speed is fast, and the gas flow rate can be adjusted in time according to the instructions of the control module 3, so as to ensure the stability and consistency of the pressure during the pressurization process and improve the product quality.

[0104] In a preferred embodiment, the control module 3 is a programmable logic controller (PLC), and the image collector 22 is a (high-precision) camera.

[0105] Specifically, the camera captures the image information of the target object 4 through the principle of optical imaging, and then uses the internal image processing algorithm to analyze the image, identify the key position features of the target object 4, and then output accurate target positioning data.

[0106] The programmable logic controller can flexibly modify the control program according to different production process requirements and characteristics of the target object 4. Receive the target positioning data transmitted by the image collector 22. The programmable logic controller processes the target positioning data according to the preset program logic and algorithm, calculates the position and size of the pressure required to be applied by the upper and lower roller components, and then outputs the corresponding pressure control signal.

[0107] A control method for a roller pressure automatic adjustment system, referring to Figure 4 , used to control the roller pressure automatic adjustment system, including,

[0108] Step S1, the image collector 22 acquires the position data of the target object 4, compares the position data with a preset standard position, and obtains the roller offset;

[0109] Step S2, obtaining target positioning data according to the roller offset calculation, the target positioning data including the detection center point and four offset base points;

[0110] Step S3, the control module 3 receives the target positioning data and outputs a pressurization control signal according to the target positioning data;

[0111] In step S4 , the upper roller pressing component 23 presses the upper surface of the target object 4 under the action of the pressing control signal, and the lower roller pressing component 24 presses the lower surface of the target object 4 under the action of the pressing control signal.

[0112] Specifically, the present invention also provides a control method for a roller pressurizing automatic adjustment system, which is used to control the roller pressurizing automatic adjustment system to perform a pressurizing action on a screen on a production line. The target object 4 refers to the screen on the production line. The image acquisition device 22 is used to collect position data of the target object 4, which is transmitted to the control module 3 after processing. The control module 3 outputs a pressurizing control signal to the upper roller pressurizing component 23 and the lower roller pressurizing component 24, which can ensure the consistency of the pressurizing position and pressure.

[0113] The upper roller pressurizing assembly 23 and the lower roller pressurizing assembly 24 work together, and the forces offset each other, thereby avoiding deformation during the pressurizing process. The pressurizing position can be adjusted according to the sizes of different screens, with high compatibility and low investment cost.

[0114] The image collector 22 collects the position data of the target object 4, converts the physical position information of the target object 4 into a digital image signal, and then analyzes it through an internal image processing algorithm. By comparing the collected position data with the preset standard position, the offset of the roller relative to the ideal pressure position can be obtained.

[0115] The target positioning data is calculated based on the roller offset, which involves geometric calculations and coordinate transformation principles. By analyzing the offset, the positions of the detection center point and the four offset base points are calculated, providing an accurate position basis for subsequent pressurization control.

[0116] The control module 3 outputs a pressure control signal according to the target positioning data, and the signal acts on the upper roller pressure component 23 and the lower roller pressure component 24 at the same time.

[0117] In terms of control principle, the control module 3 converts the target positioning data into control instructions for the driving device through the internal control algorithm, so that the upper roller 232 and the lower roller 242 pressurize the target object 4 with the same pressure and synchronous action.

[0118] Based on the precisely controlled pressurization method and according to the principle of mechanics, it can ensure that the upper and lower surfaces of the target object 4 are subjected to uniform force, thereby avoiding uneven deformation caused by single-sided force.

[0119] The entire control method realizes automated operation, reducing the time and labor costs required for manual operation.

[0120] During the production process, the system quickly collects position data, calculates target positioning data and outputs pressurization control signals, achieving fast and continuous pressurization operations. Since the accuracy of pressurization position and pressure is guaranteed, rework due to quality problems is reduced, thereby shortening the product production cycle and improving production efficiency.

[0121] Based on the adaptive adjustment capability of the position data of the target object 4, no matter how the size, shape and material of the target object 4 change, the system can obtain its position data through the image collector 22, and then calculate the corresponding target positioning data and pressure control signal according to the established control algorithm. The data-driven control strategy enables the system to flexibly adapt to different production needs without large-scale changes to the hardware, which reflects strong adaptability and versatility.

[0122] In a preferred embodiment, referring to Figure 6 , Figure 7 In step S2, the detection center point is obtained by using the following formula:

[0123]

[0124] Among them, (X5, Y5, R) represents the detection center point;

[0125] (X0, Y0, R) represents the center point of the standard position;

[0126] W represents the width of the target object 4;

[0145] (X2, Y2, R) represents the second offset base point;

[0146] W represents the width of the target object 4 .

[0147] Specifically, Figure 6 The line connecting point ① and point ② before the offset is compared with the line connecting point ① and point ② after the offset. The red arrow indicates the reference center point A of the line connecting point ① and point ② before the offset, and the green arrow indicates the detection center point B of the line connecting point ① and point ② after the offset. The roller offset (X, Y, R) is obtained by comparison.

[0148] Among them, the position of the detection center point B is compared with the position of the reference center point A to obtain the offset X in the X direction and the offset Y in the Y direction. The connecting line of point ① and point ② before the offset is compared with the connecting line of point ① and point ② after the offset to obtain the offset angle R.

[0149] Figure 7 The standard position center point of the target object 4 is C (X0, Y0, R). The detection center point B (point 5) of the line connecting the offset points ① and ② is generated after the offset. The target positioning data is calculated by the roller offset (X, Y, R). The target positioning data includes the detection center point (point 5) and four offset basic points (point 1, point 2, point 3, and point 4).

[0150] The rolling track points of the upper roller 232 and the lower roller 242 are ① to ③. After the X and Y offsets, the roller tracks are kept consistent with the edge of the screen. After the R offset, they remain parallel to the edge of the screen. The following is a table of the detection center point of the target object 4 after the offset and the positions of the four offset basic points.

[0151]

[0152] Specifically, refer to Figure 5 The image collector 22 collects the position data of the screen to be pressurized, and sends the position data to the control module 3 through the roller pressurizing robot 1. The detection center point of the offset target object 4 and the positions of the four offset basic points are calculated through the visual algorithm.

[0153] The control module 3 sends a control signal to the upper roller pressing assembly 23 and the lower roller pressing assembly 24. The control module 3 receives the visual positioning data, adjusts the position of the roller pressing robot 1 after processing, compensates for the differences in tooling and components, and ensures the consistency of the rolling position.

[0154] The upper roller pressure component 23 receives the control signal, and the electric cylinder 234 drives the upper roller 232 to apply pressure to the target object 4 under the action of the control signal.

[0155] The lower roller pressure assembly 24 receives the control signal, and the proportional valve 244 controls the air flow of the cylinder 243 under the action of the control signal. The cylinder 243 then drives the lower roller 242 to move, exerting an upward reaction force on the target object 4.

[0156] The force sensor 233 feeds back the collected pressure of the upper roller 232 to the control module 3, and the control module 3 dynamically adjusts the height and pressure of the electric cylinder 234 according to the feedback data to ensure the accuracy and stability of the roller mechanism action.
