Description

Technical Field

[0001] This invention relates to the field of lamination technology, and more particularly to a lamination testing system for adhesive bonding. Background Technology

[0002] Most portable electronic products have electronic displays, and the assembly process involves assembling these displays. XL adhesive is widely used to secure various components of the display, such as the glass panel, LCD, LED, and backlight, ensuring their stability and precise alignment during assembly. To further enhance the bonding strength of XL adhesive, it needs to be compressed to ensure full contact between the adhesive and the surface.

[0003] In existing pressing equipment, the pressing head assembly is used to press the corresponding components of the display screen. The pressing head assembly is driven by the same drive module. However, the part to be processed is not a complete plane. Some parts have curved surfaces or unevenness. This results in uneven force on the working surface of the pressing head assembly. That is, the pressing force is greater at the protruding points, which can easily damage the workpiece and affect the product yield.

First, the image acquisition mechanism acquires the image information of the workpiece and uploads the image information to the control module. The control module generates a preset planning path based on the image information. The pressing mechanism is driven to move to the starting position of the preset planning path, and the lifting mechanism drives the pressing mechanism to descend to a preset height, so that the pressing head assembly presses against the surface of the workpiece. At this time, the pressing sensor detects the pressure value of the corresponding pressing head assembly and uploads it to the control module. The control module adds the pressure values ​​of several pressing head assemblies to obtain the total pressure value. The stress on the workpiece is determined by comparing the total pressure value with a preset pressure threshold. When the total pressure value reaches the preset pressure threshold, the pressure on the workpiece is determined. When the pressure is less than or equal to a preset pressure threshold, the pressing mechanism moves along a preset planned path. When the total pressure exceeds the preset pressure threshold, the lifting mechanism drives the pressing mechanism to move upward a preset distance, thereby reducing the pressure on the workpiece. This pressing detection equipment can quickly formulate a preset pressing path by using real-time image information acquired by the imaging mechanism, thus improving production efficiency. At the same time, by monitoring the pressing force in real time through sensors, it can automatically adjust the pressure when the workpiece surface is uneven, avoiding excessive pressure at a single location and reducing the risk of workpiece damage. Because it can automatically adjust the pressing force, it reduces product damage caused by uneven force, thereby improving the product yield. Attached Figure Description

Detailed Implementation

[0049] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0050] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0051] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0052] This invention provides a tension adhesive pressing detection system, including a lifting mechanism 10 and a control module 100, a pressing mechanism 20 disposed at the drive end of the lifting mechanism 10, and an image acquisition mechanism 30 disposed on the pressing mechanism 20; the lifting mechanism 10, the pressing mechanism 20, and the image acquisition mechanism 30 are electrically connected to the control module 100 respectively; the pressing mechanism 20 includes a first mounting plate 21 and a plurality of pressing head assemblies 22 slidably connected to the first mounting plate 21 in a vertical direction, each pressing head assembly 22 and the first mounting plate 21 are provided with a first elastic element 23, and a pressing sensor 24 is disposed at one end of the first elastic element 23; wherein, the first elastic element 23 is a spring; the first elastic element 23 provides an elastic buffering function to avoid hard contact with the workpiece and to protect the workpiece.

[0053] The image acquisition mechanism 30 is used to acquire image information of the workpiece and upload it to the control module 100. The control module 100 generates a preset planned path based on the image information. The pressure sensor 24 is used to detect the pressure value of the corresponding pressure head assembly 22 and upload it to the control module 100. The control module 100 adds the pressure values ​​of several pressure head assemblies 22 to obtain a total pressure value. When the total pressure value is less than or equal to a preset pressure threshold, the pressure mechanism 20 moves along the preset planned path. When the total pressure value is greater than the preset pressure threshold, the lifting mechanism 10 drives the pressure mechanism 20 to move upward a preset distance.

[0054] It should be noted that the lifting mechanism 10 drives the pressing mechanism 20 to move upwards by a preset distance. The amount of movement of the lifting mechanism 10 needs to be planned. The planning process is as follows: calculate the difference between the total pressure value and the preset pressure threshold, and set a step-like mapping table between the difference and the amount of movement; for example, when the difference exceeds 10% of the preset pressure threshold, the movement is 1mm; when the difference exceeds 20% of the preset pressure threshold, the movement is 2mm. It can be flexibly set according to actual needs to maximize the protection of the workpiece and improve efficiency.

[0055] The working principle of this invention is as follows: During operation, the workpiece is placed sequentially below the pressing mechanism 20. First, the image acquisition mechanism 30 acquires the image information of the workpiece and uploads it to the control module 100. The control module 100 generates a preset planned path based on the image information. The pressing mechanism 20 is driven to move to the starting position of the preset planned path, and the lifting mechanism 10 drives the pressing mechanism 20 to descend to a preset height, so that the pressing head assembly 22 presses against the surface of the workpiece. At this time, the pressing sensor 24 detects the pressure value of the corresponding pressing head assembly 22 and uploads it to the control module 100. The control module 100 adds the pressure values ​​of several pressing head assemblies 22 to obtain a total pressure value. The total pressure value is compared with a preset pressure threshold to determine the stress condition of the workpiece. When the total pressure value is less than a certain threshold, the pressure sensor 24 detects the pressure value of the corresponding pressing head assembly 22 and uploads it to the control module 100. The control module 100 adds the pressure values ​​of several pressing head assemblies 22 to obtain a total pressure value. The total pressure value is compared with a preset pressure threshold to determine the stress condition of the workpiece. When the pressure is equal to or equal to a preset pressure threshold, the pressing mechanism 20 moves along a preset planned path; when the total pressure value is greater than the preset pressure threshold, the lifting mechanism 10 drives the pressing mechanism 20 to move upward a preset distance, thereby reducing the pressure on the workpiece; compared with the pressing equipment in the prior art, this pressing detection equipment can quickly formulate the preset planned path for pressing by the control module 100 through the real-time image information obtained by the image acquisition mechanism 30, thereby improving production efficiency; at the same time, by monitoring the pressing force in real time through sensors, it can automatically adjust the pressure when the workpiece surface is uneven, avoid excessive pressure at a single position, reduce the risk of workpiece damage, and reduce product damage caused by uneven force due to the automatic adjustment of pressing force, thereby improving the product yield.

[0056] In this embodiment, the pressing mechanism 20 includes a second mounting plate 25, a rotary drive assembly 26 is provided on the lower end surface of the second mounting plate 25, and a third mounting plate 27 is connected to the drive end of the rotary drive assembly 26. The rotary drive assembly 26 is used to drive the third mounting plate 27 to rotate. A first drive member 28 is provided on the third mounting plate 27, and a first guide rail 29 is provided on the third mounting plate 27 along a first direction. The first mounting plate 21 is slidably connected to the first guide rail 29. The drive end of the first drive member 28 is connected to the first guide rail 29 and is used to drive the pressure head assembly 22 to move linearly along the first direction. The first direction is the length direction of the third mounting plate 27.

[0057] It should be noted that the rotating drive assembly 26 drives the pressure head assembly 22 to rotate and move, thereby adjusting the pressing angle to adapt to different preset planning paths. This has a significant effect on processing workpieces with complex shapes or workpieces that need to be pressured from different angles. By adjusting the pressing angle, this structure ensures that there are no dead corners on the surface of the workpiece, that is, every part can be effectively pressed.

[0058] At the same time, the first driving component 28 drives the pressure head assembly 22 to move linearly along the first direction, thereby realizing the adjustment of the lateral pressing position of the pressure head assembly 22.

[0059] In summary, this design is ideal for pressing operations that require flexible and precise control. By making good use of both rotary and linear movement, it ensures that every part of the workpiece is properly pressed.

[0060] Specifically, there are two first mounting plates 21, and several pressure head assemblies 22 are symmetrically arranged on the two first mounting plates 21; the first driving member 28 has an output shaft 281, a first bevel gear 282 is arranged on the output shaft 281, a second bevel gear 283 is meshed on both sides of the first bevel gear 282, a driving screw 284 is arranged on the second bevel gear 283, and a screw nut is threadedly connected to the first mounting plate 21, and the screw nut is threadedly connected to the driving screw 284.

[0061] Combination Figure 3As shown, the first mounting plate 21 in this design comprises two symmetrically arranged first mounting plates 21 and pressure head assemblies 22, with five pressure head assemblies 22 forming a group. The left and right groups of pressure head assemblies 22 can move closer or further apart under the force of the first driving member 28, adjusting the distance between them to adapt to different pressing requirements. Regardless of the workpiece size, it can be adapted by adjusting the distance between the two first mounting plates 21. This improves the processing capacity of the equipment and provides flexibility for handling workpieces of various sizes. In addition, this design also provides greater control precision, allowing for precise adjustment of the position of the pressure head assemblies 22 to adapt to specific pressing requirements.

[0062] Furthermore, a guide post 221 is provided on the first mounting plate 21 along the vertical direction, and the pressure head assembly 22 is slidably connected to the guide post 221; the pressure head assembly 22 includes a pressure head body 222, and a roller 223 is rotatably connected to the lower end face of the pressure head body 222, and the roller 223 is covered with an adhesive body; wherein, the adhesive body is a flexible material, so that when the pressure head assembly 22 contacts the surface of the display screen, it can provide a flexible contact function and avoid damaging the display screen.

[0063] In this embodiment, the adhesive bonding detection system further includes a base assembly 40, on which a support column is provided. A first linear module 50 is provided on the upper end surface of the support column. The driving end of the first linear module 50 is connected to a second linear module 60. The driving end of the second linear module 60 is connected to a lifting mechanism 10. The lifting mechanism 10 includes a fourth mounting plate 11. A second guide rail 12 is provided on the fourth mounting plate 11 along the vertical direction. A second mounting plate 25 is slidably connected to the second guide rail 12. A second driving member 13 is provided at one end of the second guide rail 12. The driving end of the second driving member 13 is connected to the second mounting plate 25 and is used to drive the second mounting plate 25 to move linearly along the vertical direction.

[0064] Combination Figure 1 As shown, in order to enable the pressing mechanism 20 to move along the preset planned path, a corresponding driving structure is set in this scheme. The driving structure in this scheme includes a first linear module 50 and a second linear module 60, thereby pushing the pressing mechanism 20 to move, so that it has two degrees of movement on the plane to adapt to the movement of the preset planned path.

[0065] In this embodiment, a plurality of sensors are spaced apart on the side wall of the fourth mounting plate 11, and a sensing plate corresponding to the sensor is provided on the second mounting plate 25. When the second driving member 13 drives the second mounting plate 25 to move linearly in the vertical direction, the sensing plate is used to pass through the corresponding sensor to generate a first electrical signal. Through the cooperation of the sensing plate and the sensor, the spatial height of the pressing mechanism 20 can be detected in real time to avoid collisions and protect the safety of the equipment.

[0066] In this embodiment, the adhesive bonding detection system further includes a conveying mechanism 70, which is located below the bonding mechanism 20. The conveying mechanism 70 includes a conveyor belt 71, one end of which is connected to a synchronous belt assembly 72, and the other end of which is connected to a motor 73. The motor 73 drives the conveyor belt 71 to rotate. Limiting plates 74 are respectively provided on both sides of the upper end face of the conveyor belt 71. Guide slopes 75 are provided on the limiting plates 74, and the guide slopes 75 are gradually moved closer to the center along the conveying direction of the conveyor belt 71. This forms a conveying space channel that is wide at one end and narrow at the other end, so as to push the workpiece to be conveyed along the correct direction and position of the conveyor belt 71, thereby improving the positional accuracy of the conveying and thus improving the accuracy of image information and preset planning paths.

[0067] Specifically, the conveying mechanism 70 is provided with a limiting component 80 at a preset position. There are two limiting components 80, which are arranged parallel and spaced apart. Each limiting component 80 includes a mounting block 81, and a first cylinder 82 is arranged vertically on the mounting block 81. The piston rod of the first cylinder 82 is connected to an extension plate 83, and a limiting baffle 84 is provided on the extension plate 83. The limiting baffle 84 is used to restrict the workpiece. By forming a limiting space between the two limiting components 80, the workpiece can be blocked and limited to a preset position on the conveyor belt 71 to facilitate the pressing operation, play a positioning role, and improve the stability during the pressing process.

[0068] As a preferred embodiment, a pushing component 90 is provided on one side of the conveyor belt 71. The pushing component 90 includes a second cylinder 91. The piston rod of the second cylinder 91 is provided with a second elastic member 92. The end of the second elastic member 92 away from the second cylinder 91 is connected to a push block 93. That is, a floating push block 93 structure is formed so that the push block 93 can always maintain good contact with the side wall of the workpiece after the second cylinder 91 is running, thereby adapting to workpieces of different widths and sizes (displays of different inches).

[0069] In this embodiment, the control module 100 includes:

[0070] The input interface unit 110 is connected to the image acquisition mechanism 30 and the pressure sensor respectively, and is used to receive image information and pressure values;

[0071] The data processing and analysis unit 120 is used to generate a preset planned path. Specifically, the data processing and analysis unit 120 includes an image processing module 121, an optimization algorithm module 122, and a pressure analysis module 123. The image processing module 121 processes the image information received from the image acquisition mechanism 30 and extracts the shape and feature point information of the workpiece. The optimization algorithm module 122 runs an optimization algorithm model to generate the preset planned path. The pressure analysis module 123 analyzes the pressure information of each pressure head assembly 22 in real time and adjusts the lifting amount of the lifting mechanism 10 according to the total pressure value.

[0072] The control output unit 130 is used to control the operation of the pressing mechanism 20 and the lifting assembly. The control output unit 130 includes a control interface for the pressing mechanism 20 and a control interface for the lifting mechanism 10. The control interface for the pressing mechanism 20 controls the action of the pressing mechanism 20 and performs the pressing operation according to the preset planning path. The control interface for the lifting mechanism 10 controls the lifting amount of the lifting mechanism 10 according to the pressure analysis results.

[0073] Storage unit 140 stores an optimization algorithm model for planning a preset planning path, which can be called by data processing and analysis unit 120.

[0074] The communication and network unit 150 is used to upload image information and preset planned paths to the cloud; and to communicate with other devices or host computers to realize remote monitoring and diagnosis.

[0075] The interaction unit 160 includes an operation interface and a display unit. The display unit is used to display the preset planned path, pressure value, and total pressure value. The operation interface provides a user interface for functions such as starting, stopping, and manually adjusting parameters.

[0076] In summary, through these components, the control unit can fully control the pressing mechanism 20, including receiving and analyzing image information, adjusting the lifting mechanism 10 according to pressure information, and generating and executing preset planned paths, ensuring the efficient, accurate and safe operation of the equipment.

[0077] It should be noted that the control module 100 generates a preset planned path based on image information, specifically including:

[0078] S1, Generate an initial path using preset rules; The generation of a preset planning path first requires an initial path. Typically, the preset rules can be generated according to a fixed pattern (such as a spiral or Z-shaped line), covering all or part of the workpiece area.

[0079] S2, the image information is processed by the image processing module 121 to extract several feature points of the workpiece; these feature points may be specific areas to be processed on the surface of the workpiece, such as protrusions, depressions or edges.

[0080] S3, set the objective function, call the optimization algorithm model to optimize the path finding of image information and several feature points to obtain the preset planned route; whereby the objective function is set to minimize the pressing time and keep the pressing pressure of each pressing head component 22 as uniform as possible; the path finding optimization includes global optimization and local optimization;

[0081] Global optimization, such as the global layout of the path, for example, the start and end sides of the path artifacts, can make the entire process smoother.

[0082] Local optimization: In local areas, routes are planned to reduce unnecessary movement and make full use of each pressure head assembly 22.

[0083] An exemplary objective function, using the solution to loop problems (such as the Traveling Salesman Problem, TSP), treats all the points that the pressure head needs to cover as nodes in a graph, and finds a path that covers all nodes with the shortest total distance.
