Description

Technical Field

[0001] This invention relates to the field of scraper technology, and in particular to a method and electronic device for detecting scraper components. Background Technology

[0002] Currently, inkjet printing equipment is usually equipped with multiple wiper blade assemblies for wiping residual ink and dust from the printhead surface. The wiper blade assembly includes wiper blades, which can prevent residual ink from causing contamination and affecting the printing effect in the next printing. In order to ensure the wiping effect, multiple wiper blade assemblies usually need to be installed at the same height.

[0003] In the process of realizing this invention, the inventors discovered that the current method for detecting scraper blades is generally to use a lever gauge for manual detection. That is, when detecting the height of the scraper blade, a lever gauge is usually used to detect each scraper blade one by one. When the detected scraper blade height differs significantly from the stated height, the scraper blade needs to be disassembled, reinstalled, and manually detected again. However, printing equipment usually uses multiple sets of scraper blade assemblies, which results in low accuracy and low efficiency of manual detection using a lever gauge. Summary of the Invention

[0004] In view of the above problems, the present invention provides a method and electronic device for detecting a scraper assembly, which overcomes the above problems.

[0005] This invention provides a method for detecting a scraper assembly, applied to a measuring device. The measuring device includes a detection stage, a driving component, and an optical detection component. The detection stage carries at least one set of scraper assemblies. The optical detection component is disposed on the detection stage and includes a emitter and a receiver. The emitter and receiver detect the height of the scraper assembly. The driving component drives one of the scraper assembly and the optical detection component to pass between the receiver and the emitter. The receiver and emitter detect the height of the scraper assembly. The method involves activating the emitter and the driving component, controlling the driving component to drive the scraper assembly between the emitter and the receiver. As the scraper assembly passes between the emitter and the receiver, light collection data from the receiver is acquired. Based on the light collection data, it is determined whether the scraper in the scraper assembly is qualified.

[0006] In one alternative embodiment, before activating the light emitter and the drive assembly, and controlling the drive assembly to drive the scraper assembly between the light emitter and the receiver, the step of connecting the pressure plate, the scraper, and the mounting base with bolts to form the scraper assembly is further included; and the scraper assembly is installed onto the testing station.

[0007] In one optional embodiment, the light beam emitted by the emitter is sheet-like in the vertical direction, and the light-receiving data includes the light-receiving height of the received light beam in the vertical direction. The step of determining whether there is a height difference in the scraper blades in the scraper blade assembly based on the light-receiving data further includes: extracting the minimum and maximum light-receiving height data from the light-receiving data and calculating the difference between the two; obtaining a preset tolerance; determining whether the difference is greater than the preset tolerance; if yes, determining that the scraper blades in the scraper blade assembly are unqualified; if no, determining that the scraper blades in the scraper blade assembly are qualified.

[0008] In one optional embodiment, the step of obtaining the preset tolerance further includes: obtaining the identifier of the scraper assembly installed on the support plate; and extracting the preset tolerance corresponding to the identifier from the preset identifier preset tolerance reference library according to the identifier.

[0009] In one optional embodiment, the measuring device further includes a display, and the method further includes: acquiring the lowest height corresponding to the lowest point of the beam when the beam from the emitter fully reaches the receiver, and the total beam height; acquiring the receiving height of the receiving data; calculating the difference between the total beam height and the receiving height to obtain an occlusion difference value; and controlling the display to show the occlusion difference value.

[0010] In one optional embodiment, the measuring device further includes an alarm; the method further includes: if it is determined that the scraper in the scraper assembly is unqualified, controlling the alarm to output an unqualified alarm signal; if it is determined that the scraper in the scraper assembly is qualified, controlling the alarm to output a qualified signal.

[0011] In one optional embodiment, the method further includes: when it is determined that the scraper in the scraper assembly is unqualified, removing the unqualified scraper from the scraper holder; reinstalling the scraper on the scraper holder by changing the compression amount, and returning it to the measuring device for re-inspection; after the scraper assembly is disassembled and re-inspected N times, if the scraper assembly passes the test, the scraper assembly is recorded as a standard part; if all scraper assemblies are unqualified, the scraper assembly is recorded as a scrapped part, where N is an integer greater than 1.

[0012] In one alternative implementation, when it is determined that the scraper in the scraper assembly is qualified, the scraper assembly is recorded as a standard part.

[0013] According to another aspect of the present invention, an embodiment of an electronic device is provided, including at least one processor and a memory connected to the at least one processor; wherein the memory is used to store computer programs or instructions, and the at least one processor is used to execute the computer programs or instructions in the memory, wherein when the computer programs or instructions are executed by the processor, the display device performs a method for detecting a scraper assembly.

[0014] The method for detecting a scraper assembly provided in this invention is applied to a measuring device. The measuring device includes a detection stage, a driving component, and an optical detection component. The detection stage is used to support at least one set of scraper assemblies. The optical detection component is disposed on the detection stage and includes a light receiver and a light emitter. The light receiver and the light emitter are used to detect the height of the scraper in the scraper assembly. The driving component is used to drive one of the scraper assembly and the optical detection component so that at least one set of the scraper assembly passes between the light receiver and the light emitter. After the scraper assembly is installed on the detection stage, the light emitter and the driving component are activated. The drive assembly is controlled to drive the scraper assembly to pass between the emitter and the receiver. When the scraper assembly passes between the emitter and the receiver, the receiver's light-collecting data is acquired. Based on the light-collecting data, the difference between the maximum and minimum light-collecting data of the scraper is calculated. The difference is compared with a preset tolerance to determine whether the scraper in the scraper assembly is qualified. If the scraper is unqualified, it is disassembled and re-inspected. If the scraper is still unqualified after a preset number of N inspections, it is marked as a scrapped part. Qualified scrapers will be used as standard parts. Through the above method, the scraper inspection efficiency is higher and the inspection accuracy is more reliable. Attached Figure Description

Detailed Implementation

[0018] To facilitate understanding of the present invention, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them.

The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0020] Please see Figure 1The scraper assembly 10 includes a scraper 11, a mounting base 12, and a pressure plate 13. The scraper 11 is provided with a first connecting hole 111, the mounting base is provided with multiple fixing screw holes 121, and the pressure plate 13 is provided with multiple second connecting holes 131. When assembling the scraper assembly 10, a bolt passes through a first connecting hole 111 and a second connecting hole 131 of the scraper 11 in sequence and is screwed into a fixing screw hole 121. The pressure plate 13 and the mounting base 12 clamp the scraper 11, thereby fixing the scraper 11. When the scraper 11 is clamped and squeezed by the pressure plate 13 and the mounting base 12, the lower end of the scraper 11 will be compressed and thinned, while the upper end of the scraper 11 will bulge, resulting in a change in the height of the scraper 11. Furthermore, the height change of the scraper blade 11 is affected by the amount of compression at the lower end of the scraper blade 11. Generally, the greater the amount of compression at the lower end of the scraper blade 11, the larger the protrusion at the upper end of the scraper blade 11. Conversely, the smaller the amount of compression at the lower end of the scraper blade 11, the smaller the protrusion at the upper end of the scraper blade 11.

[0021] like Figure 2 and Figure 3 As shown, Figure 2 This is a graph showing the measurement data corresponding to the compression and protrusion of the 18 scraper blades 11. Figure 3 It is a line graph showing the compression and protrusion amounts corresponding to the 18 scraper blades 11. Figure 2 The horizontal axis represents the serial number of the scraper blade 11, the vertical axis represents the compression amount of the scraper blade 11, and the number in the middle represents the amount of protrusion at the upper end of the scraper blade assembly 10. Figure 3 In the diagram, the vertical axis represents the amount of protrusion at the top of the scraper 11, the horizontal axis represents the serial number of the scraper 11, and the line is formed by connecting the protrusion amounts corresponding to the compression amounts of the 18 scraper assemblies 10. Figure 2 and Figure 3 It is evident that the compression amount is A > B > C > D > E, and the lines corresponding to compression amounts A, B, C, D, and E are distributed sequentially from top to bottom. This means that the greater the compression amount, the greater the bulge. However, when installing the scraper assembly 10, it is difficult for operators to precisely control the compression amount of the scraper 11. Therefore, after installation, the height of the scraper 11 needs to be checked. If the height of the scraper 11 deviates significantly from the preset height, the user can adjust it promptly to ensure that the height of the scraper 11 is as consistent as possible with the preset height. Therefore, a method for checking the scraper assembly is needed, as follows: Please see Figure 5 and Figure 6 The method includes the following steps: Step S1: Control the drive assembly to drive the scraper assembly to pass between the light emitter and the light receiver.

[0022] The light beam emitted by the emitter 221 is sheet-like in the vertical direction. When the scraper assembly 10 passes between the receiver 222 and the emitter 221, and the height of the scraper assembly 10 is the same, the height of the light beam emitted by the emitter 221 blocked by the scraper is the same. If the height of the scraper assembly 10 is inconsistent, the area of ​​the light beam blocked by the scraper is different, so that the height of the light beam received by the receiver 222 is inconsistent.

[0023] Before the drive assembly 23 drives the scraper assembly 10 to pass between the light emitter 221 and the light receiver 222, the pressure plate 13, scraper 11 and mounting base 12 need to be connected by bolts to form the scraper assembly 10, and the scraper assembly is installed on the detection table 21.

[0024] It is worth noting that before the detection begins, the heights of the emitter 221 and receiver 222 need to be adjusted so that the scraper 11 of the scraper assembly 10 falls within the range of the beam emitted by the emitter 221.

[0025] Step S2: As the scraper assembly passes by the light emitter and the light receiver, acquire the light receiving data from the light receiver; The light-receiving data is the data generated by the light receiver 222 after the light emitter 221 is activated, which includes the light-receiving height of the light beam received by the light receiver 222.

[0026] Step S3: Based on the light-receiving data, determine whether there is a height difference in the scraper blades of the scraper assembly.

[0027] Since the area of ​​the light beam blocked by the scraper assembly 10 is different when the height of the scraper blades 11 of the scraper assembly 10 is inconsistent, the light receiving height of the light beam received by the receiver 222 is inconsistent. Therefore, by judging whether the light receiving heights recorded in the light receiving data are all the same, it can be determined whether there is a height difference in the scraper blades 11 of the scraper assembly 10.

[0028] In this embodiment of the invention, multiple scraper assemblies 10 are driven to pass between the light emitter 221 and the light receiver 222. Then, based on the light received by the light receiver 222, it is determined whether there is a height difference between the multiple scrapers 11 of the multiple scraper assemblies 10, thereby realizing automatic detection of the scraper assemblies 10. Furthermore, the measurement accuracy using the optical detection assembly 22 is higher.

[0029] Since achieving identical heights for all scraper blades 11 across multiple scraper blade assemblies is quite challenging, a preset tolerance can be set. As long as the height difference between the scraper blades 11 in the scraper blade assembly 10 is within the preset tolerance range, they are considered to have identical heights. For details, please refer to [link to relevant documentation]. Figure 6 Step S4 includes: Step S31: Extract the data of minimum and maximum light collection height from the light collection data, and calculate the difference between the two; When the scraper 11 is higher, the area of ​​the beam blocked by the scraper 11 is larger, and the beam received by the receiver 222 is smaller. Therefore, the scraper that blocks the most beam corresponds to the scraper with the smallest beam height, and the scraper with the highest beam height corresponds to the scraper that blocks the least beam height, and the scraper with the largest beam height corresponds to the scraper with the lowest beam height.

[0030] Step S32: Obtain the preset tolerance; Preset tolerances are pre-defined data, such as preset tolerances of 0.3 mm, 0.5 mm, etc.

[0031] Step S33: Determine whether the difference is greater than the preset tolerance; Step S34: If yes, then determine that the scraper in the scraper assembly is defective; Step S35: If not, then determine that the scraper in the scraper assembly is qualified.

[0032] Since different scraper assemblies allow different height differences between their blades—for example, scraper assembly A allows a height difference of 1 mm, while scraper assembly B allows a height difference of 1.5 mm—the presence of a height difference between the blades in the scraper assembly 10 can be detected based on the different scraper assemblies 10. For details, please refer to [link to relevant documentation]. Figure 7 Step S32 further includes: Step S321: Obtain the identification of the scraper assembly installed on the support plate; The identifier is a unique code for the scraper assembly. This identifier can be manually entered by the user or determined by identifying the scraper assembly 10 through a camera image.

[0033] Step S322: Based on the identifier, extract the preset tolerance corresponding to the identifier from the preset identifier tolerance reference library.

[0034] The preset marking tolerance reference library refers to a database that records the correspondence between the markings of the scraper components and the preset tolerances.

[0035] In this embodiment of the invention, by determining the identifier of the scraper assembly 10 and determining the corresponding preset tolerance based on the identifier, and then determining the height between the scrapers of the multiple scraper assemblies 10 based on the preset tolerance and combined with the light-receiving data, different detection standards are implemented according to different scraper assemblies 10.

[0036] Please see Figure 8 , Figure 8This is a flowchart of a method for detecting the scraper assembly 10 according to another embodiment of the present invention. This embodiment differs from the above embodiment in that... (See attached diagram). Figure 8 The method also includes: Step S5: Obtain the lowest height corresponding to the lowest point of the beam when the light beam from the emitter completely reaches the receiver, and the total beam height; When the emitter and receiver are fixed, the lowest and highest positions of the beam in the vertical direction are fixed, and the overall beam height is also fixed.

[0037] Step S6: Obtain the light collection height of the light collection data; Step S7: Calculate the difference between the total beam height and the light receiving height to obtain the occlusion difference value; The occlusion difference is the height of the beam obstructed by the scraper.

[0038] Step S8: Control the display to show the occlusion difference of the scraper.

[0039] In this invention, the occlusion difference of the scraper blade is calculated and displayed in real time, which allows users to easily and intuitively see the occlusion difference of the scraper blade.

[0040] Please see Figure 9 , Figure 9 This is a flowchart of a method for detecting a scraper assembly according to another embodiment of the present invention. This embodiment differs from the previous embodiments in that the method further includes: Step S9: If it is determined that the scraper blade in the scraper blade assembly is defective, control the alarm to output a defective alarm signal; Step S10: If it is determined that the scraper in the scraper assembly is qualified, then control the alarm to output a qualified signal.

[0041] By outputting non-compliance and compliance signals, users can promptly know whether the scraper assembly is qualified. Furthermore, if it fails, the scraper can be disassembled, reinstalled, and retested. Therefore, the method also includes: Step S11: When it is determined that the scraper in the scraper assembly is defective, the defective scraper is removed from the scraper holder; Step S12: Reinstall the scraper blade in the scraper blade holder by changing the compression amount, and return to the measuring device for retesting; Step S13: After the scraper assembly is disassembled and re-inspected N times, if the scraper assembly passes the test, the scraper assembly is recorded as a standard part; if the scraper assembly fails the test, the scraper assembly is recorded as a scrapped part. N is an integer greater than 1.

[0042] In this embodiment of the invention, the scraper 11 is manually reinstalled. The amount of protrusion of the scraper 11 is related to the tightness of the bolts when reinstalling the scraper 11 with the scraper seat 12 and the pressure plate 13. If the scraper is found to be unqualified, the compression amount is changed and the scraper is reinstalled. However, if the scraper is still unqualified after N reinstallations and tests, it means that it is no longer a situation that can be adjusted by adjusting the compression amount. It is a hard defect of the scraper itself. Therefore, if the scraper is still unqualified after N tests, it is directly marked as a scrap part and is not used.

[0043] Step S14: Record the scraper assembly as a standard part.

[0044] Previously, during the assembly of inkjet printing equipment, the squeegee assembly 10 was manually installed on the maintenance panel. If multiple squeegee assemblies 10 needed to be installed, each squeegee 11 in the multiple squeegee assemblies 10 had to be installed on the maintenance panel one by one with the mounting base 12, pressure plate 13, and bolts. Then, a lever gauge was used for testing. The accuracy of the lever gauge was low, and the accuracy of the test was related to the operator's skill level. Moreover, testing each squeegee one by one was very inefficient. When installing multiple squeegee assemblies 10, a lot of time was required to test the squeegees. If the test failed, the squeegee assembly 10 had to be disassembled, reassembled, and tested again. In addition, the inkjet printing equipment also had inkjet devices, etc., which left little space for adjusting the squeegee assembly 10, making it very inconvenient. Using the above method, the required scraper blades 11, mounting base 12, pressure plate 13, and bolts are first assembled into a single structure. Multiple scraper blade assemblies 10 can be tested simultaneously; the specific number to be tested depends on the requirements. If a scraper blade fails, it can simply be removed from the scraper blade holder, reinstalled, and tested again on the testing bench. When the scraper blade assembly 10 passes the test, it can be used directly as a standard part. When installing the scraper blade assembly 10 on the maintenance panel, the operator can directly install the pre-tested, qualified scraper blade assembly 10 onto the maintenance panel. No further testing is required after installation, as the scraper blade assembly 10 has been pre-tested and formed a standard part. Therefore, extensive operator experience is not required, and installation can still be completed quickly and successfully.

[0045] The method for detecting a scraper assembly provided in this embodiment of the invention is applied to a measuring device 20. The measuring device 20 includes a detection stage 21, a driving component 23, and an optical detection component 22. The detection stage 21 is used to carry at least one set of scraper assemblies 10. The optical detection component 22 is disposed on the detection stage 21 and includes a light emitter 221 and a light receiver 222. The light emitter 221 and the light receiver 222 are used to detect the height of the scraper 11 in the scraper assembly 10. The driving component 23 is used to drive one of the scraper assembly 10 and the optical detection component 22, so that at least one set of the scraper assembly 10 passes between the light receiver 221 and the light emitter 222. After the scraper assembly 10 is installed on the detection stage 21, the light emitter 222 is activated. The drive component 23 controls the drive component 23 to drive the scraper component 10 to pass between the light emitter 221 and the light receiver 222. When the scraper component 10 passes between the light emitter 221 and the light receiver 222, the light receiving data of the light receiver 222 is acquired. Based on the light receiving data, the difference between the maximum and minimum light receiving data of the scraper 11 is calculated. The difference is compared with the preset tolerance to determine whether the scraper 11 in the scraper component 10 is qualified. If the scraper is unqualified, the scraper 11 is disassembled and re-inspected. If the scraper is still unqualified after a preset number of N inspections, the scraper 11 is recorded as a scrapped part. The qualified scraper 11 will be used as a standard part. In this way, the scraper inspection efficiency is higher and the inspection accuracy is more reliable.
