Description

TECHNICAL FIELD

[0002] Release film is a special functional film widely used in electronic, printing, packaging and other industries. Its core function is to provide surface release effect, which facilitates material layering, peeling or transfer. Due to the high performance requirements of the application field of release film, strict quality control standards are required in the production process to ensure product consistency and reliability.

[0003] Among the main quality control standards of release film, release force and mechanical strength are key indicators for evaluating the surface performance and physical performance of release film. The release force refers to the peeling force between the release film and the adhered material. If the release force is too high, it may cause peeling difficulty, and if it is too low, it may cause the material to fall off prematurely. The mechanical strength refers to the tensile strength, tear strength and puncture resistance of the release film to cope with mechanical stress in the production and use process.

[0004] For the above key indicators, current sampling detection of release film in laboratory environment can only be carried out by using different equipment (such as peeling force tester, universal material testing machine, etc.), but this detection method requires special operators to spend time and effort to detect, resulting in low detection efficiency.

DETAILED DESCRIPTION

[0020] The application will be further described in detail below with reference to the accompanying drawings. Figures 1-3 The application will be further described in detail below with reference to the accompanying drawings.

[0021] The embodiment of the present application discloses a multi-sensor fusion release film quality online evaluation system.

[0022] Referring to Figure 1 The multi-sensor fusion release film quality online evaluation system comprises a coating liquid pool 1, an unwinding roller 2, a winding roller 3, a pulling mechanism 4, a guiding mechanism 5, a fixing mechanism 6, a visual module and a control module.

[0023] The coating liquid pool 1 is hollow inside and open at the upper end, and the inside is provided with an adhesive for adhering to the surface of the release film, and the coating liquid pool 1 is arranged along the conveying direction of the release film. The unwinding roller 2 is arranged at one end of the coating liquid pool 1, and the width direction of the unwinding roller 2 is consistent with the width direction of the coating liquid pool 1. The pulling mechanism 4 is arranged above the coating liquid pool 1 and connected with the winding roller 3, for supporting the winding roller 3 and applying a pulling force to the winding roller 3. An operator can first wind one end of the release film, which has not been coated with adhesive, on the unwinding roller 2, and the other end of the release film is wound on the winding roller 3 after being guided by the guiding mechanism 5. The winding roller 3 is provided with a detection unit for detecting the quality parameters of the release film. In the embodiment, the detection unit is a piezoelectric force sensor, which can be arranged on the roller frame of the winding roller 3 and located at the inlet of the film, so that the release film first contacts the detection end of the detection unit and then is wound on the winding roller 3. The winding roller 3 and the unwinding roller 2 both comprise a roller frame, a roller barrel rotatably connected to the roller frame and a rotating motor for driving the rotation of the roller barrel, and both adopt the existing technology, so the specific description is not expanded.

[0024] Referring to Figure 2 The guiding mechanism 5 moves between the upper side of the coating liquid pool 1 and the obliquely lower side of the winding roller 3 and is arranged away from the unwinding roller 2. The guiding mechanism 5 contacts the upper surface of the release film and is used for guiding the lower surface of the release film to be close to the liquid surface of the adhesive. Then the guiding mechanism 5 moves away from the coating liquid pool 1 to provide space for subsequent detection. Then the pulling mechanism 4 applies a pulling force to the winding roller 3 to drive the winding roller 3 to move one end of the release film, and the release force of the release film is detected by the detection unit. Therefore, the conveying track of the release film is as follows: the release film comes out from the unwinding roller 2, passes above the coating liquid pool 1, contacts the guiding mechanism 5, is conveyed upward and is wound on the winding roller 3.

[0025] The fixing mechanism 6 is located on one side of the coating liquid pool 1 and is used for fixing the release film and the guiding mechanism 5 after the release force is detected, so as to facilitate the pulling of the release film by the pulling mechanism 4 for detecting the mechanical strength of the release film. The visual module is arranged above one side of the conveying path of the release film and is used for obtaining the conveying position of the release film. The control module is electrically connected with the unwinding roller 2, the winding roller 3, the guiding mechanism 5, the fixing mechanism 6, the pulling mechanism 4, the detection unit and the visual module. The control module is configured as follows: S110, if the quality evaluation requirement information is obtained (when the winding roller 3 winds a small amount of release film, for example: after the winding roller 3 winds three turns, the user is reminded to press the button pre-installed on the device to initiate the quality evaluation requirement), the viscosity consistency detection is performed, and if the detection result indicates that the viscosity meets the standard, the release film adhesive process is performed; Regarding the viscosity consistency detection, the specific settings are as follows: A detection tube 11 is fixedly connected to the bottom of the coating liquid pool 1, an electromagnetic valve is installed on the detection tube 11, a photoelectric opposite sensor is installed 2 cm below the lower pipe opening of the detection tube 11, and the liquid drops vertically pass through the light beam; the control module performs viscosity consistency detection, which includes: S111, obtaining the detection signal feedback by the photoelectric opposite sensor; It can be understood that the photoelectric opposite sensor is composed of a pair of infrared emitters and receivers. When the adhesive drops, the liquid drops will interrupt the infrared light beam, and the sensor will generate an electrical signal (such as a pulse signal).

[0026] S112, based on the detection signal, recording the number of liquid drop falling and the time interval, and calculating the falling speed; It can be understood that by recording the number of times and the time interval of the interruption of the infrared light beam, the falling speed can be calculated, such as: drop frequency = drop number / time.

[0027] S113, based on the falling speed, searching the preset database to determine the matched liquid viscosity; It can be understood that the drop speed-liquid viscosity relationship data table is pre-stored in the database. According to the drop speed, the corresponding liquid viscosity can be obtained by looking up the table.

[0028] S114, if the matched liquid viscosity meets the preset standard viscosity, output the viscosity meets the standard prompt.

[0029] It can be understood that the standard viscosity can be a unified standard range for testing; the viscosity meets the standard prompt can be that the green light pre-installed on the device is turned on, and then the release film adhesive process can be performed.

[0030] Regarding the release film adhesive process, it includes: S120, controlling the guide mechanism 5 to guide the release film to approach the adhesive liquid surface, and controlling the winding speed of the winding roller 3 to be less than the unwinding speed of the unwinding roller 2; It can be understood that the guide mechanism 5 moves and approaches the lower surface of the release film to the adhesive liquid surface, and controls the respective rotating speeds of the winding roller 3 and the unwinding roller 2, so that the release film passing above the coating liquid pool 1 can relax and vertically drop into the coating liquid pool 1 due to gravity, and the release film can be adsorbed on the adhesive surface due to the adsorption force between the liquid and the film.

[0031] S121, acquire image data fed back by the vision module, process the image data, and identify the position of the release film; It can be understood that the image data collected by the camera can determine whether the release film located above the coating liquid pool 1 falls into the coating liquid pool 1.

[0032] S122, if it is identified that the release film is adsorbed to the adhesive liquid surface, control the winding roller 3 and the unwinding roller 2 to stop moving, and control the guide mechanism 5 to move to a preset point away from the adhesive liquid surface (that is, the guide mechanism 5 is moved away from the release film transmission track to prevent the guide mechanism 5 from interfering with the subsequent detection of the release force, for example, moving to the obliquely upward direction away from the release film), and then performing a quality evaluation process; The quality evaluation process includes: S130, acquire detection data fed back by the detection unit; It can be understood that the detection unit includes a piezoelectric force sensor, which can be arranged on the roller frame of the winding roller 3 and located at the film inlet, so that the release film can contact the detection end of the detection unit for detecting the change of force.

[0033] S131, control the pulling mechanism 4 to execute the release force detection instruction, and call the detection data after the current time and define it as data one. It can be understood that the release force detection instruction refers to the pulling mechanism 4 applying a transient pulling force to the winding roller 3, so that the winding roller 3 moves one end of the release film, so that the release film adsorbed to the adhesive liquid surface is pulled up from the liquid surface instantaneously, and the data curve detected by the detection unit will suddenly increase and then decrease to present a gentle trend, at which time the pulling mechanism 4 is controlled to stop moving.

[0034] S132, based on data one, perform release force evaluation analysis to obtain evaluation result one and output; It can be understood that the data detected by the detection unit in this process is called and analyzed, which can be dynamically displayed by the obtained data one through the curve and data processing analysis to obtain the required release force. The data processing analysis process adopts the prior art.

[0035] S133, if a signal is received after the output of the evaluation result one (i.e., the measured release force data) is completed, control the fixing mechanism 6 to move; It can be understood that the release force is detected first, and after the evaluation result one is obtained, the mechanical strength detection is performed, which needs to be fixed by the fixing mechanism 6 to facilitate the test by pulling the release film by the winding roller 3.

[0036] S134, if a signal is received after the fixing mechanism 6 is completed, control the pulling mechanism 4 to execute the mechanical strength detection instruction, and call the detection data after the current time and define it as data two. It can be understood that the mechanical strength detection instruction refers to the pulling mechanism 4 applying a constant force to the winding roller 3 to pull the winding roller 3 to move, and since the fixing mechanism 6 fixes the release film, when the winding roller 3 is pulled, the data detected by the detection unit is called and analyzed, the data curve shows a gradually rising trend from flat, and when the data curve drops sharply and is approximately zero when the release film is torn, it means that the release film has been torn, and the mechanical strength detection is completed, and the pulling mechanism 4 stops acting.

[0037] S135, based on the data two, the mechanical strength evaluation analysis is carried out, the evaluation result two is obtained and output.

[0038] It can be understood that the data two is dynamically displayed in a curve, and the existing data processing technology is used to process and analyze the data two to obtain the mechanical strength data.

[0039] Through the above setting, the release film can be detected on the system of the application in sequence for its release force and mechanical strength parameters, without the need to replace different equipment for detection, saving manpower, being able to timely evaluate the quality of the release film online, and improving the detection efficiency.

[0040] Reference Figure 1 With Figure 2 , the pulling mechanism 4 includes a support 41, a support plate 42, a pulling rod 43 and a power unit 44, the support 41 is erected on both sides of the liquid pool 1, the support plate 42 is fixedly connected to the top of the support 41 in a horizontal manner, and the support plate 42 is located above the liquid pool 1 and the unwinding roller 2, so that the release film from the unwinding roller 2 passes between the support plate 42 and the liquid pool 1. One end of the pulling rod 43 is hinged to the upper surface of the support plate 42, and the other end of the pulling rod 43 is fixedly connected to the roller frame of the winding roller 3 and does not hinder the rotation of the winding roller 3. The power unit 44 is arranged on the upper surface of the support plate 42 and connected to the pulling rod 43, for applying force to the pulling rod 43 to drive the pulling rod 43 to rotate, thereby driving the winding roller 3 to move.

[0041] The power unit 44 is electrically connected to the control module, and the control module is configured to: If the signal fed back after the fixing mechanism 6 completes the action is received, the power unit 44 is controlled to rotate the pulling rod 43 at a constant speed.

[0042] Through the above setting, when the mechanical strength of the release film is detected, the power unit 44 controls the pulling rod 43 to rotate at a constant speed, so that the pulling rod 43 can move the winding roller 3 at a constant speed, and the release film is pulled for detection, so that the data detection is more accurate. An encoder can be installed on the rotating shaft at the hinge between the pulling rod 43 and the support plate 42 to monitor the rotating speed of the pulling rod 43 and feed back to the power unit 44.

[0043] The power unit 44 comprises a sliding block 441, a power motor 442, a pulling rope 443 and a reset spring 444. The sliding block 441 is slidably connected to the upper surface of the support plate 42 in the horizontal direction. The power motor 442 is installed at the end of the support plate 42 away from the winding roller 3. The output shaft of the power motor 442 is coaxially fixed with a winding drum. One end of the pulling rope 443 is fixedly connected to the outer wall of the winding drum, and the other end is fixedly connected to the side wall of the sliding block 441. The end of the support plate 42 away from the power motor 442 is fixedly connected with a vertical limiting plate 445. One end of the reset spring 444 is fixedly connected to the side wall of the limiting plate 445 towards the sliding block 441, and the other end is fixedly connected to the side wall of the sliding block 441 away from the pulling rope 443. The upper part of the sliding block 441 is fixedly connected with a connecting rod 446, and the top of the connecting rod 446 is fixedly connected with a horizontal slide rod which is in a cylindrical shape. A slide groove is formed in the lower surface of the pulling rod 43 along the length direction of the pulling rod 43 for the slide rod to slide. The cross section of the slide groove is in a T shape. The power motor 442 is electrically connected to the control module.

[0044] Through the above arrangement, when the release force detection instruction is executed, the power motor 442 is controlled to instantaneously wind the pulling rope 443, pull the sliding block 441 to instantaneously move quickly, and drive the slide rod to move in the slide groove of the pulling rod 43, so that the pulling rod 43 drives the winding roller 3 to instantaneously rotate and pull up the release film from the liquid pool 1. When the mechanical strength detection instruction is executed, the power motor 442 is controlled to uniformly wind the pulling rope 443, so that the pulling rod 43 can pull the winding roller 3 to move at a constant speed, and the mechanical strength of the release film is detected.

[0045] Referring to Figure 1 With Figure 3 The guide mechanism 5 comprises a guide rod 51 with smooth surface and in contact with the release film, and a moving assembly 52 connected to the guide rod 51. The guide rod 51 is arranged in the width direction of the release film and located above the liquid pool 1. The moving assembly 52 comprises a horizontal moving unit 521, a lifting unit 522 and a vertical rod 523. The horizontal moving unit 521 is arranged at one side of the liquid pool 1. In this embodiment, the horizontal moving unit 521 is a linear motor, and the lifting unit 522 is an electric push rod. The vertical rod 523 is vertically arranged and the bottom thereof is installed on the moving part of the horizontal moving unit 521, and the moving part of the horizontal moving unit 521 can move along the length direction of the liquid pool 1. The main body of the lifting unit 522 is fixedly connected to the top of the vertical rod 523, and one end of the guide rod 51 is fixedly connected to the lifting part of the lifting unit 522, so that the guide rod 51 can move up and down and left and right.

[0046] Through the above setting, before the release force detection, the horizontal moving unit one 521 and the lifting unit 522 can control the guide rod 51 to drive the release film close to the liquid surface of the adhesive. After the release film is adsorbed on the adhesive liquid surface, the guide rod 51 needs to be away from the release film to prevent interference with the winding roller 3 pulling the release film for release force detection. Therefore, by moving the guide rod 51 towards the direction close to the unwinding roller 2 and also upwards by the horizontal moving unit one 521 and the lifting unit 522, that is, away from the adhesive liquid surface, a moving space is provided for the release film to separate from the adhesive. It can be understood that the guide rod 51 is moved to the moving track of the release film after the subsequent winding roller 3 pulls the release film from the adhesive liquid surface. It should be noted that the release film moves towards the guide rod 51 after being pulled from the adhesive liquid surface, and the release film will again contact the guide rod 51, which is convenient for the subsequent fixing mechanism 6 to fix the release film.

[0047] With reference to Figure 3 , the fixing mechanism 6 includes a horizontal moving unit two 61, a vertical rod 62, a sleeve rod 63, and a cylinder 64. The horizontal moving unit two 61 is arranged on the side of the liquid pool 1 away from the horizontal moving unit one 521. In this embodiment, the horizontal moving unit two 61 is a linear motor. The moving part of the horizontal moving unit two 61 moves along the width direction of the liquid pool 1. The vertical rod 62 is fixedly connected to the moving part of the horizontal moving unit two 61. The sleeve rod 63 is arranged horizontally along the width direction of the liquid pool 1, and one end of the sleeve rod 63 is fixedly connected to the top side wall of the vertical rod 62.

[0048] With reference to Figure 2 And Figure 3 When the guide rod 51 is located at the preset point away from the adhesive liquid surface, the sleeve rod 63 is aligned with the guide rod 51. The guide rod 51 is fixedly connected to the end face of the sleeve rod 63 in a columnar protrusion. The diameter of the protrusion is smaller than the diameter of the guide rod 51. The end face of the sleeve rod 63 towards the guide rod 51 is axially provided with a groove for the protrusion. The cylinder 64 is a miniature small stroke cylinder and is embedded in the top of the vertical rod 62. The cylinder 64 is fixedly connected to a clamping rod 65 parallel to the sleeve rod 63, and the clamping rod 65 is located above the sleeve rod 63. The horizontal moving unit two 61 and the cylinder 64 are electrically connected to the control module.

[0049] Through the above setting, when the guide rod 51 moves away from the adhesive liquid level point, the sleeve rod 63 is just aligned with the guide rod 51. After the release film is detected by the winding roller 3 to detect the release force, the release film is in contact with the guide rod 51 again. The horizontal moving unit two 61 moves the sleeve rod 63 towards the guide rod 51, so that the protrusion extends into the groove, and the sleeve rod 63 is spliced with the guide rod 51. At this time, the clamping rod 65 is located above the guide rod 51 and the release film. The clamping rod 65 is controlled to descend by the air cylinder 64, so that the clamping rod 65 clamps the release film. The rubber pads are sleeved outside the clamping rod 65 and the sleeve rod 63 to increase the friction, so as to fix the position of the release film, which is convenient for the subsequent pulling rod 43 to pull the winding roller 3 to pull the release film.

[0050] In another embodiment of the present application, considering that the release film is transparent, in order to clearly obtain the conveying position of the release film, the vision module comprises a camera and a line laser (not shown in the figure). The line laser is arranged above the side of the release film and is inclined to irradiate on the surface of the release film, so that the laser beam forms an acute angle with the surface of the release film, and the line laser beam covers the width direction of the release film. The camera is arranged above the side of the release film, and the visual angle thereof captures the laser feature position formed by the line laser on the release film, so that the camera can clearly collect the image of the release film. Through the existing recognition model, the image is processed and recognized to obtain the conveying state and position of the release film.

[0051] In another embodiment of the present application, in order to make the viscosity of the adhesive in the coating liquid pool 1 uniform, a stirring mechanism (not shown in the figure) is arranged in the coating liquid pool 1. The stirring mechanism is electrically connected to the control module, and the control module is configured to: if the quality evaluation requirement information is acquired, control the stirring mechanism to execute the stirring instruction.

[0052] In the present embodiment, the stirring mechanism adopts the existing propeller stirrer. After the quality evaluation requirement initiated by the user is acquired, the stirring mechanism is controlled to stir the adhesive uniformly, and then the viscosity consistency detection is performed, so that the viscosity detection is more accurate.

[0053] The present application also discloses a multi-sensor fusion release film quality online evaluation method.

[0055] The above are the preferred embodiments of the present application, but do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
