Description

Technical Field

[0001] The utility model relates to the technical field of printed paste materials, in particular to a printed paste material resistance value testing device. Background Art

[0002] Printed paste, also known as conductive paste, is a specialized electronic material. Functionally classified into conductive carbon paste and conductive silver paste, it is widely used in the electronics industry, particularly in the wiring of thick-film integrated circuits, electrodes for ceramic capacitors, and leads for hybrid integrated circuits. It can also be used as an electrode material in industries such as solar cells, as well as in printed circuits and electronic packaging.

[0003] In the process of producing printed paste, texture uniformity is a very important indicator because it directly affects the conductive performance and reliability of the paste. However, due to process, equipment or human factors, the texture of the printed paste may sometimes be uneven.

[0004] For example, improper control of process parameters, equipment failure, or human error due to changes in production specifications or batches, or differences in raw materials, can lead to uneven mixing of the slurry. For example, insufficient stirring speed or insufficient stirring time can cause uneven distribution of conductive particles in the slurry, resulting in agglomeration or sedimentation. Equipment failures such as a damaged agitator or clogged pipes can also lead to uneven slurry mixing. In addition, human errors such as incorrect raw material ratios or improper addition order can also adversely affect the texture of the slurry.

[0005] When the printed paste has an uneven texture, its overall resistance is affected. This is because the uneven distribution of conductive particles hinders the flow of current through the paste, increasing resistance. Furthermore, uneven texture can reduce the paste's adhesion, resulting in a weak bond between the film and the substrate, thus affecting its conductivity and reliability.

[0006] Therefore, for the existing printed paste production line, a device capable of testing the printed paste is urgently needed. To this end, a printed paste resistance test device is proposed. Utility Model Content

[0007] In view of this, the embodiments of the present invention hope to provide a printed paste resistance test device to solve or alleviate the technical problem existing in the prior art, namely how to test the resistance performance of the printed paste, and at least provide a useful option for this purpose; the technical solution of the present invention is implemented as follows:

[0008] A printed paste resistance tester is described. The printed paste to be tested is placed in a container 2, which has sufficient volume to accommodate the paste. A current sensor 201 is mounted on the inner bottom wall of container 2 to detect the current flowing through the paste. A test assembly 4, located above container 2, is designed to discharge the paste within the container. The discharge angle is universally adjustable to accommodate different testing requirements.

[0009] Adjustment component 3 is in adjustable series electrical contact with the slurry. By adjusting the contact method and degree, the resistance value in the circuit can be adjusted. When discharge begins, current flows from test component 4 through the slurry and is detected by current sensor 201 at the bottom of the container. Current sensor 201 then transmits the detected current magnitude and flow time information to controller 5.

[0010] After receiving this information, controller 5 calculates the resistance and conductance of the slurry according to Ohm's law. This entire testing process can be performed on a randomly selected amount of slurry within a production batch to reflect the resistance and process performance of the entire batch. If personnel detect any abnormality in the parameters displayed on controller 5 (which requires a display screen), operators immediately stop production and investigate the issue.

[0011] In one embodiment, the device further comprises a housing 1 , the container 2 is placed at the lower end of the housing 1 , the testing component 4 and the adjusting component 3 are both located at the upper end of the housing 1 ; and the controller 5 is disposed in the housing 1 .

[0012] In one embodiment, the adjustment component 3 is designed to include at least two resistors 303 with different resistance values. The varying resistance values ​​of these resistors 303 enable the test device to adapt to a variety of resistance testing environments. In actual operation, one of the resistors 303 is connected in series with the printed paste, so that current flowing through the paste also flows through this resistor 303. The remaining resistors 303 are selectively connected in series or not in series with the resistor 303 already connected in series with the paste, depending on the specific resistance testing requirements.

[0013] This design allows the tester to flexibly adjust the total resistance value in the circuit, thereby simulating different operating environments or test conditions. By increasing or decreasing the number of resistors 303 in series or changing their combination, the resistance value in the circuit can be precisely controlled, thereby providing a more comprehensive and accurate assessment of the conductive properties of the slurry.

[0014] In one embodiment, the test assembly 4 is designed to include at least three linear actuators 401. These linear actuators 401 are arranged in a circular array facing the printed paste and connected to the exterior of a base 402. Each linear actuator 401 features linear adjustment. When linearly moving, they coordinately control universal adjustment of the base 402. This design allows the base 402 (and the discharge electrode 403 thereon) to be flexibly adjusted in position and angle to accommodate diverse testing requirements.

[0015] Electrodes 403 for discharge are located on the exterior of base 402. When a discharge test is required, electrodes 403 release charge, which is then conducted through the printed slurry to the bottom of container 2 and ultimately detected by current sensor 201. By measuring and analyzing the magnitude and duration of the current, the resistance and conductance of the printed slurry can be calculated.

[0016] Furthermore, linear actuator 401 is implemented as a servo cylinder. A servo cylinder is a high-precision linear motion device whose piston rod is hinged to base 402 via a universal joint. This connection not only ensures flexible rotation between the piston rod and base 402, but also enhances the stability and reliability of the entire test assembly 4.

[0017] In one embodiment, the adjustment assembly 3 includes a base 301 and a slider 302. The base 301 is positioned along the length of the container 2, while the slider 302 is capable of sliding along the base 301. A scale is printed on the base 301 to accurately indicate the sliding distance of the slider 302, thereby enabling precise control of the test position. All resistors 303 are fixed to the slider 302 and move as the slider 302 slides.

[0018] A test assembly 4 is located at the bottom of slider 302. Specifically, it includes at least three servo cylinders (linear actuators 401) and a base 402. The servo cylinders are universally connected to the bottom of slider 302 via universal joints, enabling test assembly 4 to perform universally adjustable discharge tests.

[0019] During testing, container 2 is first left to rest for a period of time, allowing the printed paste to naturally settle and settle. Then, by sliding slider 302, test assembly 4 is moved along the length of container 2 to test the resistance of the printed paste in different areas of container 2. In each test area, test assembly 4 performs a universally adjustable discharge test to ensure a more comprehensive and comprehensive test result.

[0020] It's important to note that during the universal adjustment discharge test, the servo cylinder's adjustment angle relative to electrode 403 should be limited to a minimum to ensure that the current can be detected by current sensor 201, positioned perpendicularly below it. Therefore, in this test mode, the current flow time detected by current sensor 201 may not be the primary test criterion, with the focus instead on the magnitude of the detected current. The precise value of the current flow time is determined by the test results with electrode 403 and a specific current sensor 201 positioned perpendicularly relative to each other.

[0021] In one embodiment, at least two current sensors 201 are arranged in an array below the container 2. The distance between these current sensors 201 corresponds to the distance that the slider 302 moves each time, ensuring that each test area has a vertically corresponding current sensor 201 to capture and measure current. A scale on the base 301 accurately determines whether the slider 302 has reached the position of the current sensor 201 that vertically corresponds to the current test area. Once the slider 302 has reached the correct position, the test assembly 4 activates the test.

[0022] During the test, the controller 5 only reads the data from the current sensor 201 that first detected current. The advantage of this design is that, if the printed slurry is uniform and free of foreign matter, the controller 5 should be able to read the same current flow time and current magnitude regardless of which current sensor 201 the slider 302 slides vertically above. This is because a uniform slurry should have consistent conductivity across all regions.

[0023] However, if the current flow time or current magnitude read in any test is different from the previous test value, the resistance value of the paste is considered unqualified. This change may be due to foreign matter in the paste, uneven texture, or other factors that cause differences in conductive properties.

[0024] In one embodiment, a relay 6 is further included. The input end of relay 6 is connected to a power source for receiving electrical energy. The output end of relay 6 is electrically connected to electrode 403 of test assembly 4, thereby supplying energy for the discharge process. In short, relay 6 acts as a switch, controlling the connection between the power source and electrode 403.

[0025] The controller is connected to the relay 6 and can control the on / off state of the relay 6. When a discharge test is required, the controller instructs the relay 6 to connect to the electrode 403, so that the power supply can be supplied to the electrode 403, thereby performing a discharge test. When discharge is not required, the controller controls the relay 6 to disconnect, thus cutting off the connection between the power supply and the electrode 403.

[0026] Furthermore, during the discharge test, the controller also records the time that relay 6 is connected to electrode 403. This allows the current sensor 201 to determine the duration of the current flow based on the recorded connection time. This information is crucial for subsequent analysis of the conductive properties of the slurry.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. Comprehensiveness and Accuracy: This new device precisely controls the test assembly at different locations within the container, ensuring comprehensive and accurate resistance measurement of printed pastes. This design avoids blind spots and errors that can occur with traditional methods, improving the reliability of test results.

[0029] Flexibility and Adaptability: The test assembly of this utility model features a universally adjustable design, adapting to discharge testing requirements at various angles and positions. This flexibility allows the device to accommodate containers of various shapes and sizes, as well as slurries of varying properties, thereby expanding its application range. It can also rapidly and continuously measure resistance at multiple test points, significantly improving testing efficiency. Furthermore, the controller processes and records test data in real time, reducing the complexity and error rates associated with manual operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of the specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] Example: In the prior art, for the existing printed paste production line, there is an urgent need for a device that can test the printed paste; for this purpose, please refer to Figure 1-5 This embodiment provides a related technical solution to solve the above technical problems: a printed paste resistance test device, including a container 2 storing printed paste, the printed paste has a resistance value based on the volume of the container 2, and a current sensor 201 is provided on the inner bottom wall of the container 2; a current sensor 201 is provided above the container 2.

[0039] A test assembly 4, which is capable of discharging the printed paste in the container 2 and the discharge angle is universally adjustable;

[0040] An adjusting component 3, which is in electrical contact with the printed paste in an adjustable series manner and adjusts the resistance value;

[0041] When the discharge starts, current flows through the printed plasma until it is detected by the current sensor 201. The current sensor 201 transmits the current magnitude and flow time to the controller 5. The controller 5 calculates the resistance and conductance of the printed plasma according to Ohm's law.

[0042] During use, a certain amount of printed paste produced by the printed paste production line is randomly selected from a production batch and submitted to this device for testing to reflect the resistance process performance of the entire batch of printed paste. If the performance is poor, the production line must be immediately stopped and the defect point must be identified.

[0043] Specifically, the device operates based on Ohm's law, which states that resistance is equal to the ratio of voltage to current. Discharging the slurry through the test assembly 4 generates a known voltage. Current sensor 201 detects the current flowing through the slurry and transmits the current magnitude and duration to controller 5. Based on the received current and the known voltage, controller 5 uses Ohm's law to calculate the resistance of the slurry. Furthermore, since conductance is the inverse of resistance, controller 5 can also calculate the conductance of the slurry.

[0044] Specifically, in addition to the above functions, the controller 5 is also used to connect and control all electrical components of the entire device to be driven according to a pre-set program as a preset value and drive mode; it should be pointed out that the above drive mode corresponds to the corresponding start and stop time intervals, speed, power and other output parameters between the relevant electrical components below, that is, it meets the requirements of the relevant electrical components described below to drive the relevant mechanical devices to operate according to the functions described therein.

[0045] The design of adjustment component 3 allows for adjustable resistance during testing, thereby simulating different test conditions or correcting for test errors. (Therefore, the current total resistance of adjustment component 3 should be subtracted before applying Ohm's law to the above calculations.) By testing randomly selected slurry materials within a production batch, the average resistance and resistance distribution of the batch can be calculated, thereby assessing whether the process performance of the batch of slurry materials meets requirements.

[0046] It can be understood that in the above scheme: the printed paste resistance testing device has multiple functions: first, it can accurately measure the resistance value of the printed paste, providing important data for evaluating the conductive properties of the paste; second, by adjusting the adjustment function of component 3, different working environments or test conditions can be simulated to make the test results more valuable for reference; in addition, the device can also measure and calculate the conductivity value of the paste, providing supplementary information for a comprehensive understanding of the conductive properties of the paste.

[0047] In practical applications, this device can be used for quality control in printed paste production lines. By randomly selecting a certain amount of paste for testing, quality issues in the production process can be promptly identified and corrective measures can be taken. This not only improves production efficiency and quality stability, but also reduces production costs and resource waste. Furthermore, the device's design offers flexibility and scalability, adapting to the testing needs of different paste types and specifications.

[0048] In this example, see Figures 1 and 2 : It also includes a casing 1, a container 2 is placed at the lower end of the casing 1, a testing component 4 and an adjusting component 3 are both located at the upper end of the casing 1; and a controller 5 is arranged in the casing 1.

[0049] In this example, see Figure 3 The adjustment component 3 includes at least two resistors 303 with different resistance values, wherein one resistor 303 is electrically connected to the printed paste in a series connection, and the remaining resistors 303 are connected in series or not in series with the previous resistor 303 according to the resistance test environment.

[0050] Specifically, this embodiment is based on the series characteristic of resistors, i.e., the total resistance in a series circuit is equal to the sum of the individual resistors. By connecting one or more resistors 303 in series with the printed paste, the total resistance of the circuit can be increased. Since each resistor 303 has a different resistance value, the total resistance of the circuit can be flexibly adjusted by selecting different resistors 303 for series connection.

[0051] Furthermore, since the current is equal everywhere in the series circuit, the current flowing through the slurry is the same as the current flowing through the series resistor 303. This enables the current sensor 201 to accurately detect the current flowing through the slurry and transmit this information to the controller 5 for calculation and processing.

[0052] It can be understood that in the above scheme: by flexibly adjusting the number and combination of series resistors 303, a variety of different working environments or test conditions can be simulated, thereby making a more comprehensive and accurate evaluation of the conductive properties of the slurry; secondly, since the resistance value of each resistor 303 is different, the total resistance value in the circuit can be accurately controlled, improving the accuracy and reliability of the test; finally, the design also has the advantages of simple operation, convenience and speed, making the testing process more efficient and convenient. In practical applications, this design can be widely used in the quality control link of printed slurry production lines and the performance testing link in the product development stage. By randomly selecting a certain amount of slurry for testing and adjusting the production process or product formula in a timely manner according to the test results, it can be ensured that the produced slurry products have good conductive properties and a stable quality level.

[0053] In this example, see Figure 3 : The test assembly 4 includes at least three linear actuators 401. All linear actuators 401 are arranged in a circular array facing the printed paste and connected to the outside of the base 402. When each linear actuator 401 is adjusted linearly, the base 402 can be controlled to make universal adjustments; an electrode 403 for discharge is provided on the outside of the base 402.

[0054] Preferably, the linear actuator 401 is a servo electric cylinder, and the piston rod of the servo electric cylinder is hinged to the base 402 through a universal joint coupling.

[0055] Specifically, this embodiment relies on the precise control capabilities of a linear actuator (servo cylinder) and the flexible rotational characteristics of a universal joint coupling. By controlling the linear motion of the servo cylinder's piston rod, the base 402 can be precisely adjusted in position and angle. The universal joint coupling ensures a flexible connection between the piston rod and base 402, allowing the entire test assembly 4 to adapt to diverse testing environments and requirements.

[0056] Meanwhile, the discharge process of electrode 403 follows the basic principle of charge conduction. When electrode 403 releases charge, the charge is conducted through the printed paste and ultimately detected by current sensor 201. By measuring and analyzing the magnitude and duration of the current flow, Ohm's law can be used to calculate the resistance and conductance of the printed paste.

[0057] It can be understood that in the above scheme, the coordinated control of at least three linear actuators 401 enables universal adjustment of the base 402, allowing the discharge electrode 403 to flexibly adjust its position and angle to suit different testing requirements. Furthermore, the servo cylinder's high-precision control ensures test accuracy and reliability. Finally, the flexible rotation of the universal joint coupling enhances the adaptability and stability of the entire test assembly 4. This design not only improves test efficiency and quality but also provides strong support for subsequent data analysis and processing.

[0058] It is understandable that in the above scheme: the form of at least three linear actuators 401 and their universal joint couplings is equivalent to a parallel mechanism. For those skilled in the art, a conventional parallel mechanism can be used to store a preset program using a PID controller algorithm, that is, to achieve the universal angle adjustment function according to the corresponding time step.

[0059] In this example, see Figure 3 The adjustment assembly 3 includes a base 301 and a slider 302 that slides along the length of the container 2. A scale (not shown in the figure) is printed on the base 301 to indicate the sliding distance of the slider 302. All resistors 303 are fixed on the slider 302.

[0060] A test assembly 4 is provided at the bottom of the slider 302; the cylinder body of the servo electric cylinder is universally hinged to the bottom of the slider 302 through a universal joint coupling;

[0061] During the test, the container 2 can be left still for a period of time to wait for the printed paste to naturally settle and become still; the slider 302 can be slid to enable the test component 4 to test the resistance value of the printed paste in different areas of the container 2, and perform a universally adjusted discharge in each area to achieve a more comprehensive and comprehensive test. Based on the above test mode, the angle of the servo cylinder when performing universal adjustment on the electrode 403 cannot be too large, and it must be ensured that it can be captured by the current sensor 201 perpendicular to it. Therefore, the current flow time detected by the current sensor 201 during universal angle adjustment can be used as a detection standard instead of a detection standard, and only the current size can be detected. The current flow time shall be based on the test value of the relative vertical posture of the electrode 403 and a certain current sensor 201.

[0062] Specifically, the principle of this embodiment is based on a combination of sliding adjustment and universal discharge testing. By sliding slider 302, it is possible to test the printed slurry in different areas of container 2; while the universal adjustment discharge test ensures more comprehensive and accurate test results. Furthermore, a scale allows for precise control of the sliding distance and position of slider 302, thereby improving test accuracy and reliability. Furthermore, the use of a servo cylinder and universal joint coupling ensures the flexibility and stability of the test assembly 4.

[0063] During the universal adjustment discharge test, it's important to carefully control the servo cylinder's adjustment angle relative to electrode 403 to ensure accurate current capture and measurement. Furthermore, because the current flow time can be affected by angle changes, a specific test posture (such as a relatively vertical posture) is required in actual testing to accurately obtain the current flow time value. This is why, in this test mode, the current magnitude is more important than the flow time.

[0064] It can be understood that in the above scheme: through the combination of sliding adjustment and universal discharge testing, comprehensive and accurate testing of the printed paste in different areas of container 2 can be achieved; secondly, the use of a scale can accurately control the test position and distance, improving test accuracy; thirdly, the use of servo cylinders and universal joint couplings ensures the flexibility and stability of the test assembly; finally, accurate current flow time values ​​are obtained through specific test postures, further improving the accuracy and reliability of the test. This design not only improves test efficiency and quality, but also provides strong support for subsequent data analysis and processing. At the same time, the design also has certain versatility and scalability, and can adapt to the testing needs of printed pastes of different specifications and types.

[0065] In this example, see Figure 5At least two current sensors 201 are arranged in an array below the container 2. The distance between the current sensors 201 corresponds to the distance that the slider 302 slides each time. Specifically, a scale is used to determine whether the slider 302 has slid to the current sensor 201 that vertically corresponds to the current test area, and then the test assembly 4 is activated to perform the test. The controller 5 only reads the current sensor 201 that first detects current (due to the vertical relationship). The advantage of this mode is that if the printed paste is free of foreign matter or is prepared with uniform texture, the controller will read the same current flow time and current magnitude regardless of which current sensor 201 the slider 302 slides vertically above each time. Otherwise, if any value is no longer the same as the previously tested value, the paste resistance is deemed unqualified.

[0066] Specifically, this embodiment utilizes a current sensor array and a sliding test assembly. By precisely controlling the sliding distance and position of slider 302, each test area is ensured to have a corresponding current sensor 201 to capture and measure current. Controller 5 only reads the data from the current sensor 201 that first detects current, ensuring the accuracy and consistency of test results.

[0067] Ideally, if the slurry is uniform and free of foreign matter, the current flow time and magnitude should be the same regardless of the test location. This is because a uniform slurry has consistent conductive properties across all areas. However, if test results vary, it can be inferred that there may be a problem with the slurry, such as the presence of foreign matter or an uneven texture.

[0068] It can be understood that in the above scheme: the array of current sensors 201 and the precisely controlled sliding test assembly enable comprehensive and accurate testing of different areas of the slurry. Secondly, the controller 5 only reads the data from the current sensor 201 that first detects current, ensuring the accuracy and consistency of the test results. Finally, by comparing the test results of different areas, potential problems with the slurry, such as foreign matter and uneven texture, can be promptly identified. This design not only improves testing efficiency and quality, but also provides strong support for the preparation and quality control of slurries.

[0069] In this example, see Figure 4 : Also includes a relay 6, the input end of the relay 6 is connected to the power supply, the output end of the relay 6 is electrically connected to the electrode 403 of the test component 4 and realizes the energy supply for the discharge;

[0070] The controller controls the connection to the relay 6 to control its disconnection connection or connection to the electrode 403; when the relay 6 is connected to the electrode 403, the connection time is recorded so that when the current sensor 201 detects the current, the time when the current flows can be determined.

[0071] Specifically, this embodiment utilizes relay 6 to control the connection between the power source and electrode 403, thereby achieving precise control over the discharge process. In response to commands from the controller, relay 6 quickly establishes a connection between the power source and electrode 403 when needed, enabling the discharge process. It then promptly disconnects the connection when it is no longer needed, avoiding unnecessary energy consumption and potential safety hazards.

[0072] At the same time, by recording the time when relay 6 is connected, the time information of the current flow can be accurately obtained. This information is of great reference value for analyzing the conductive properties of the slurry, judging its quality, and optimizing the preparation process.

[0073] It can be understood that in the above scheme: by introducing the combination of relay 6 and controller, precise control of the discharge process is achieved, thereby improving the accuracy and reliability of the test; secondly, by recording the path time, information on the current flow time is obtained, which provides strong support for subsequent data analysis and processing; finally, this design also has certain flexibility and scalability, and can adapt to the testing needs of different specifications and types of slurries.

[0074] The above-described embodiments merely represent implementation methods for the relevant practical applications of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person of ordinary skill in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
