Only actuators that pass the tests can meet quality requirements. The tester needs to install the actuator on the corresponding model coating die before testing.

[0004] 1. In actual working conditions, the actuator is connected to the coating die head, and the tail end of the coating die head is connected to the actuator. The actuator directly contacts the coating slurry. During the coating process, the slurry will form a certain cavity pressure inside the coating die head, and this cavity pressure will produce additional resistance to the actuator. However, when the coating die head is currently used to test the actuator, due to the limitations of laboratory conditions, the actual coating slurry is usually not used in the aging test on the coating die head, resulting in the lack of resistance to the actuator imposed by the cavity pressure under actual working conditions, affecting the test results and the delivery quality of the actuator.

DETAILED DESCRIPTION

[0057] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0058] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a", "an" and "an" as used herein may also be meant to include the plural forms. The terms "comprise", "include" and "have" are inclusive and therefore specify the presence of stated features, elements and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0059] Although the terms first, second, etc. may be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms may only be used to distinguish one element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. In addition, in the description of the present invention, unless otherwise clearly specified and limited, the terms "set" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0060] For ease of description, spatial relative terms can be used in the text to describe the relationship of an element or feature relative to another element or feature as shown in the figure, and these relative terms are, for example, "front", "rear", "middle", "inside", "longitudinal", "lateral", "side", "vertical", "outside", etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation in addition to the orientation depicted in the figure. For example, if the mechanism in the figure flips, the element described as "below other elements or features" or "below other elements or features" will be subsequently oriented to "above other elements or features" or "above other elements or features". Therefore, the example term "below..." can include the orientation on and below. The mechanism can be oriented in addition (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.

[0061] Before leaving the factory, the actuator (including motor or electric cylinder) is usually subjected to aging test and life test. Only the actuator that passes the test can meet the quality requirements. The tester needs to install the actuator on the corresponding model coating die before testing.

[0062] However, the current use of coating dies to perform aging tests on actuators has the following problems:

[0063] 1. In actual working conditions, the actuator is connected to the coating die head. The coating die head is a device used in the coating process to evenly coat the slurry on the substrate. The tail end of the coating die head is connected to an actuator, which directly contacts the coating slurry. The function of the actuator is to drive the coating die head for coating operations. During the coating process, the slurry will form a certain cavity pressure inside the coating die head, and this cavity pressure will produce resistance to the actuator in the opposite direction of the coating direction. However, when the actuator is tested using the coating die head, due to the limitations of laboratory conditions, the actual coating slurry is usually not used in the aging test on the coating die head, which means that the test is carried out under the condition of no slurry cavity pressure. In the absence of slurry, the actuator will not be subject to the resistance generated by the cavity pressure in the actual working conditions. This lack will cause the test results to not fully reflect the performance of the actuator under the actual working conditions. Due to the lack of cavity pressure resistance under actual working conditions, the test results may underestimate or overestimate the performance of the actuator in actual work, thereby affecting the validity and reliability of the test.

[0064] 2. During the aging test on the coating die head, there is a probability of accidents during the operation, which increases the probability of wear and damage to the coating die head. The coating die head has very strict inspection on shipment, which in turn affects the shipment of the coating die head.

[0065] 3. The production cycle of the coating die head is long, and the aging test on the coating die head prolongs the delivery cycle of the entire equipment.

[0066] Based on the above reasons, if the aging test is carried out based on the coating die head, it will inevitably lead to high labor costs, low efficiency, reduced quality, and affect normal production.

[0067] Based on this, the present invention provides a test cabinet and a test method, which utilizes the telescopic shaft of the telescopic mechanism to coaxially abut with the output shaft of the actuator, thereby simulating the resistance encountered by the actuator under actual working conditions, thereby replacing the method of using a coating die head for testing, thereby ensuring the accuracy of the test, avoiding damage to the coating die head, and shortening the production cycle of the actuator.

[0068] At present, there are still the following problems in using coating die heads to perform aging tests on actuators:

[0069] 4. The number of actuators installed on the coating die head is limited, and the test cannot be completed in one batch.

[0070] Based on this, the present invention arranges multiple rows of test mounting plates on the test cabinet, arranges multiple actuator mounting positions and multiple telescopic mechanisms on each row of test mounting plates, and makes each telescopic mechanism correspond to each actuator mounting position, thereby increasing the number of tests that can be conducted at a single time, so that the test cabinet can test multiple actuators at the same time, thereby improving the test efficiency.

[0071] The specific embodiments of the present invention are described in detail below in conjunction with the test cabinet of the first aspect of the present invention.

[0072] It should be noted that the test cabinet of the first aspect of the present invention is only a preferred embodiment of the present invention. The test cabinet of the present invention can adopt the test cabinet of the first aspect of the present invention or other structures. For the convenience of explanation, the present invention is explained below through the test cabinet of the first aspect of the present invention.

[0073] Combination Figures 1 to 4 As shown, this embodiment discloses a test cabinet, including a cabinet body and a telescopic mechanism 4. An actuator mounting position is provided on the cabinet body, and the actuator mounting position is suitable for positioning the actuator. The telescopic mechanism 4 is arranged inside the cabinet body, and the telescopic mechanism 4 has a telescopic shaft, and the telescopic shaft of the telescopic mechanism 4 is coaxially abutted with the output shaft of the actuator. When performing an aging test or a life test of the actuator, the telescopic shaft of the telescopic mechanism 4 applies pressure to the output shaft of the actuator to simulate the resistance encountered by the actuator under actual working conditions.

[0074] The above-mentioned test cabinet can simulate the operating conditions of the actuator, including the resistance encountered during operation, etc., and add a load force module (i.e., telescopic mechanism) to the test to make the test conditions more perfect. It can replace the method of using a coating die for testing, saving costs, and can perform aging tests or life tests more quickly, saving a lot of time and resources, improving test efficiency and test accuracy, and improving the delivery quality of the actuator.

[0075] When using the test cabinet for testing, there is no need to frequently replace expensive testing equipment such as the coating die head, which greatly reduces the consumption of materials and equipment. Because the use of the test cabinet for testing does not require the actuator to be installed on the coating die head, it can avoid damage to the coating die head and shorten the production cycle of the actuator. The maintenance of the test cabinet is relatively simple, reducing the cost of maintenance and repair.

[0076] By applying pressure to the output shaft of the actuator through the telescopic shaft of the telescopic mechanism 4, the resistance encountered by the actuator under actual working conditions can be accurately simulated, which helps to more realistically evaluate the performance and reliability of the actuator in actual use. The telescopic mechanism 4 can accurately control the pressure applied through a precise control system to ensure the accuracy of the test.

[0077] In addition, the test cabinet is dedicated to actuators and can also be used for aging tests or life tests of actuator products in other working conditions other than the lithium battery industry. Various actuator tests can be performed by simply adjusting the actuator installation position and the parameters of the telescopic mechanism 4.

[0078] In some embodiments, a test mounting plate 3 is detachably provided on the side wall of the cabinet. The test mounting plate 3 is provided with a mounting hole group and a through hole 32. The mounting hole group forms an actuator mounting position, and the mounting hole group includes at least one mounting hole 31. The mounting hole group on the test mounting plate 3 can accurately fix the actuator to ensure that it will not be displaced during the test, thereby improving the stability and accuracy of the test. The test mounting plate 3 can be disassembled, and the type of the test mounting plate 3 can be replaced when testing actuators of different specifications. Figure 3 As shown, one side of the test mounting plate 3 is provided with mounting holes 31 for various types of actuators, wherein the mounting holes 31 are mounting threaded holes, and the other side is provided with a cylinder for providing load conditions for the aging test.

[0079] The fixed end of the telescopic mechanism 4 is positioned on the side of the test mounting plate 3 facing away from the mounting hole group, and the telescopic shaft of the telescopic mechanism 4 is movably extended through the through hole 32 of the test mounting plate 3, so that the telescopic shaft can be coaxially docked with the output shaft of the actuator, so that the telescopic shaft of the telescopic mechanism can directly act on the output shaft of the actuator, ensuring the accuracy of the force direction.

[0080] In this embodiment, the design of the test mounting plate 3 makes the installation and removal of the actuator more convenient and quick, reducing the time of installation and debugging. The mounting hole group can adapt to different types of actuators, increasing the versatility and flexibility of the test cabinet.

[0081] In some embodiments, a plurality of mounting hole groups and a plurality of through holes 32 are provided on the test mounting plate 3, the number of the mounting hole groups is the same as the number of the through holes 32, each mounting hole group positions an actuator respectively, a plurality of telescopic mechanisms 4 are provided, and each through hole 32 corresponds to a telescopic mechanism 4.

[0082] In this embodiment, multiple actuators can be tested at the same time, which greatly improves the test efficiency, reduces the need for multiple separate test equipment, and saves equipment costs. Each telescopic mechanism 4 works independently to ensure that the output shaft of each actuator can be accurately applied force to avoid mutual interference. Multiple mounting hole groups can be adapted to actuators of different models and specifications, increasing the versatility and flexibility of the test cabinet.

[0083] In some embodiments, a plurality of test mounting plates 3 are provided, and the plurality of test mounting plates 3 are linearly spaced and arranged on the outer wall of the cabinet. Preferably, the installation direction of each test mounting plate 3 is horizontal, and the actuator installation positions are arranged along the width direction of the cabinet along the layers of test mounting plates, and the arrangement direction of each test mounting plate 3 is vertically spaced. Figure 1 There are 10 test installation plates in total, and each test installation plate has 22 actuator installation positions and 22 cylinders.

[0084] In this embodiment, the provision of multiple test mounting plates 3 can significantly increase the test capacity of the test cabinet, so that more actuators can be tested at the same time, thereby improving the test efficiency. The linear spacing arrangement allows sufficient space between each test mounting plate 3, avoiding mutual interference and ensuring that each actuator can be tested independently. The modular design of the test mounting plate 3 allows it to be easily adjusted and replaced to adapt to different types of actuators. Each test mounting plate 3 can be fixed independently to ensure that each actuator can remain stable during the test process, avoiding displacement and vibration. The design of multiple test mounting plates 3 makes it possible to perform multiple types of tests at the same time, such as aging tests, life tests, etc., to meet different test requirements.

[0085] In some embodiments, the telescopic mechanism 4 includes a cylinder 41. The air intake pipeline and the exhaust pipeline of at least one cylinder are both arranged on a control valve 11, the control valve 11 is connected to an air intake manifold, the end of the air intake manifold is provided with a total air intake port 7, the total air intake port 7 is connected to the air source through a connecting pipe, and the control valve 11 is used to control the connection and disconnection between the cylinder 41 and the air source and the deflation of the cylinder 41, so as to control the telescopic movement of the cylinder 41.

[0086] It should be noted that the air intake and exhaust pipelines of at least one cylinder are both arranged on one control valve 11, which means that one control valve 11 can control the air intake and exhaust pipelines of one cylinder, and one control valve 11 can also control the air intake and exhaust pipelines of multiple cylinders at the same time. When one control valve 11 controls the air intake and exhaust pipelines of multiple cylinders at the same time, the air intake pipelines of each cylinder can be connected to a cylinder air intake main pipe, and the exhaust pipelines of each cylinder can be connected to a cylinder air intake and exhaust main pipe, and then the cylinder air intake main pipe and the cylinder air intake and exhaust main pipe can be connected to the control valve 11 respectively.

[0087] The control valve 11 is a two-position three-way valve. The control valve 11 can be an electric control valve or a hand valve. When the control valve 11 is a hand valve, the hand valve includes a handle, a valve body and an internal valve core. The handle is connected to the valve core. The position of the valve core is changed by rotating or turning the handle to control the on-off of the air circuit. The hand valve has three interfaces, namely the valve air inlet, the valve air outlet and the valve exhaust. The valve air inlet is connected to the air source, the valve air outlet is connected to the cylinder air inlet 42, and the valve exhaust is connected to the cylinder exhaust 43. When the hand valve is in the initial position, the valve air inlet and the valve air outlet are disconnected, and the cylinder is in a static state. Pull the handle to move the valve core to a new position, at which time the valve air inlet and the valve air outlet are connected. Compressed air enters the hand valve from the valve air inlet, and then enters the air inlet of the cylinder through the valve air outlet. Pull the handle again to return the valve core to its initial position. At this time, the valve air inlet and valve air outlet are disconnected again, the compressed air in the cylinder is sealed, and the piston stops moving. Continue to pull the handle to move the valve core to another position. At this time, the valve exhaust port and the cylinder exhaust port are connected, and the compressed air in the cylinder is discharged through the valve exhaust port.

[0088] In this embodiment, the air intake and exhaust pipelines of the cylinder 41 are both arranged on the control valve 11, which makes the pipeline layout more concise, reduces the complexity of the pipeline, and reduces the difficulty of installation and maintenance. The control valve 11 integrates the functions of air intake and exhaust, reduces additional pipelines and joints, and improves the compactness and reliability of the system. The centralized control design reduces the number of required pipelines and joints and reduces material costs.

[0089] In some embodiments, the cylinders 41 are arranged in multiple rows, and each row of cylinders 41 includes multiple cylinders. Preferably, a row of cylinders 41 is arranged on a test mounting plate 3. In this embodiment, multiple actuators can be tested at the same time, which greatly improves the test efficiency. The design of multiple rows of cylinders makes it possible to perform aging tests or life tests on multiple actuators at one time, reducing the time required for a single test and speeding up the test progress.

[0090] Each row of cylinders 41 is controlled by a control valve 11, which reduces the complexity of the control system and makes the control more centralized and efficient. Each row of cylinders 41 and the corresponding control valve 11 form a module, which makes maintenance and repair more convenient. The centralized control design reduces the number of required pipes and joints and reduces material costs.

[0091] In some embodiments, a barometer 5 and / or a pressure regulating valve 6 are provided on the intake manifold. In this embodiment, the barometer 5 can monitor the air pressure in the intake manifold in real time to ensure that the air pressure is within a safe and stable range, which helps to detect air pressure anomalies in a timely manner and prevent equipment damage or test failure caused by excessively high or low air pressure. The pressure regulating valve 6 can accurately adjust the air pressure in the intake manifold, thereby adjusting the cylinder output force, ensuring that the cylinder 41 is always in the best working state during the test, which helps to improve the accuracy and consistency of the test. Figure 1 There are two groups of pressure regulating valves 6 to control the test installation plates of the 1st to 5th layers and the 6th to 10th layers respectively, and 10 hand lever valves to control the switches of the 10th layers of cylinders respectively.

[0092] In some embodiments, the cabinet includes a first cabinet 1 and a second cabinet 2. The telescopic mechanism 4 is arranged in the first cabinet 1. A test power socket 9 that can be connected to the actuator is arranged on the side of the second cabinet 2 to provide the power required for the actuator test. The second cabinet 2 is a double-door cabinet, and a control circuit is arranged in the second cabinet 2. The control circuit is used to simulate the working current and working voltage of the actuator, and can adjust the working current and working voltage of the actuator. The control circuit can be adjusted according to different test requirements to adapt to a variety of test scenarios and conditions.

[0093] In this embodiment, the first cabinet 1 is mainly used to install the telescopic mechanism 4, and the second cabinet 2 is used to install the test power socket 9 and the control circuit. The functions are clear, and the layered design of the first cabinet 1 and the second cabinet 2 isolates the electrical part and the mechanical part from each other without interfering with each other, thereby improving space utilization.

[0094] Preferably, the first cabinet 1 and the second cabinet 2 are both rectangular cabinets, and the first cabinet 1 is arranged above the second cabinet 2, making full use of the vertical space, making the entire cabinet structure more compact and saving floor space.

[0095] In some embodiments, four rollers 10 are disposed on the lower side of the second cabinet 2 for convenient movement of the cabinet.

[0096] In some embodiments, an all-in-one machine 8 is provided on the top surface of the second cabinet 2, and the all-in-one machine 8 is used to control the aging test or life test of the actuator, and can monitor the test process in real time, which is more convenient to operate. The all-in-one machine 8 can monitor various parameters in the test process in real time, such as working current, working voltage, temperature, etc., to ensure the accuracy and consistency of the test conditions. The all-in-one machine 8 can record all data in the test process, which is convenient for subsequent data analysis and troubleshooting. The all-in-one machine 8 can detect abnormal conditions in the test process in real time, such as overvoltage, overcurrent, etc., and issue an alarm in time and take corresponding measures to prevent equipment damage or safety accidents. The all-in-one machine 8 integrates control and monitoring functions, making the operation easier, and the user can complete all control and monitoring operations on one interface.

[0097] The specific embodiments of the present invention are described in detail below in conjunction with the testing method of the second aspect of the present invention.

[0098] It should be noted that the testing method of the second aspect of the present invention is only a preferred embodiment of the present invention. The testing method of the present invention can adopt the testing method of the second aspect of the present invention or other methods. For the convenience of explanation, the present invention is explained below through the testing method of the second aspect of the present invention.

[0099] Combination Figure 5 As shown, this embodiment provides a testing method, which is performed using a test cabinet and includes the following steps:

[0100] 1) Install the actuator on the test mounting plate 3 of the cabinet, and make the output shaft of the actuator coaxially abut against the telescopic shaft of the telescopic mechanism 4, which can more realistically simulate the resistance encountered by the actuator under actual working conditions.

[0101] 2) Open the control valve 11 and apply a load force to the output shaft of the actuator through the telescopic axis of the telescopic mechanism 4 to simulate the resistance encountered by the actuator under actual working conditions, ensure that the test conditions are highly consistent with the actual use environment, and improve the reliability of the test results.

[0102] 3) Connect the test power socket 9 to the actuator through a power cord.

[0103] 4) Set up an aging test program in the software on the all-in-one machine to perform an aging test or life test on the actuator.

[0104] 5) Observe the aging test record of the integrated machine to see if the actuator has any alarm or abnormality; if an alarm occurs, disassemble the actuator for repair and proceed to step 1); if no alarm occurs, proceed to the next step.

[0105] 6) After the actuator test is completed, close the control valve and disassemble the actuator.

[0106] Before conducting aging test or life test on the actuator, the following steps are also included:

[0107] The telescopic length of the telescopic mechanism 4 is dynamically adjusted to simulate the dynamic resistance encountered by the actuator under actual working conditions. This can more realistically simulate the dynamic resistance encountered by the actuator under actual working conditions, ensure that the test conditions are highly consistent with the actual use environment, and comprehensively evaluate the performance of the actuator under different working conditions.

[0108] Connecting the test power socket 9 on the cabinet to the actuator and controlling the current and voltage of the actuator can more realistically simulate the current and voltage of the actuator under actual working conditions.

[0109] After the actuator is subjected to aging test or life test, the following steps are also included:

[0110] Observe the test record of the integrated machine 8 to check whether the actuator has any abnormality; when the actuator has any abnormality, an alarm will be automatically triggered and the actuator will be removed from the cabinet for maintenance.

[0111] The above test method can more realistically simulate the resistance encountered by the actuator under actual working conditions by coaxially connecting the output shaft of the actuator with the telescopic shaft of the telescopic mechanism, which helps to ensure that the test results can reflect the performance of the actuator in actual use. The load force is applied to the output shaft of the actuator through the control valve and the telescopic mechanism to simulate the resistance in actual working conditions, so that the test conditions are closer to the actual use environment. By ensuring that the test conditions are highly consistent with the actual use environment, the test error can be reduced and the reliability of the test results can be improved. By setting up an aging test scheme on the all-in-one machine, the actuator can be comprehensively tested, including performance tests under long-term operation and extreme conditions, to ensure its long-term stability and reliability. By observing the aging test records on the all-in-one machine, the operating status of the actuator can be monitored in real time, and abnormal situations can be discovered and handled in time. When an alarm occurs, the actuator can be quickly disassembled and repaired, and then retested to ensure that each actuator has been rigorously tested and verified.

[0112] In some embodiments, in combination Figure 6 As shown, the program control logic for performing an aging test on the actuator includes the following steps:

[0113] S1. Start the test;

[0114] S2. Select aging parameters;

[0115] S3. Select the actuator to be tested for aging and start aging;

[0116] S4. Set the current position of the actuator to the negative limit position; set the stepping direction of the actuator to the positive direction;

[0117] S5 determines whether to manually end the automatic test; when the automatic test needs to be manually ended, execute step 16; when the automatic test does not need to be manually ended, execute step S6;

[0118] S6. Determine whether the time is aged; when the time is aged, execute step S7; when the time is not aged, execute step S8;

[0119] S7. Determine whether the aging time has been reached; when the aging time has been reached, execute step S16; when the aging time has not been reached, execute step S9;

[0120] S8. Determine whether the aging times have been reached; when the aging times have been reached, execute step S16; when the aging times have not been reached, execute step S9;

[0121] S9. Determine whether the current stepping direction of the actuator is the positive direction; when the current stepping direction of the actuator is the positive direction, execute step S10; when the current stepping direction of the actuator is not the positive direction, execute step S13;

[0122] S10. Determine whether the current position of the actuator is greater than or equal to the positive limit position; when the current position of the actuator is greater than or equal to the positive limit position, execute step S11; when the current position of the actuator is less than the positive limit position, execute step S12;

[0123] S11. Set the stepping direction of the actuator to the reverse direction, and execute step S5;

[0124] S12. Control the actuator to continue to step in the positive direction and execute step S10;

[0125] S13. Determine whether the current position of the actuator is less than or equal to the negative limit position; when the current position of the actuator is less than or equal to the negative limit position, execute step S14; when the current position of the actuator is greater than the negative limit position, execute step S15;

[0126] S14. Set the stepping direction of the actuator to the positive direction, and execute step S5;

[0127] S15. Control the actuator to continue to step in the negative direction and execute step S13;

[0128] S16. Set the current position of the actuator to 0;

[0129] S17. End the test.

[0130] The program control logic for the aging test of the actuator has clear control logic for each step to ensure the accuracy and repeatability of the test process. By setting the positive limit position and the negative limit position, it is ensured that the actuator will not exceed the safety range during the test, thereby improving the safety and reliability of the test. By accurately controlling the stepping direction and position of the actuator, it is ensured that the motion trajectory during the test conforms to the actual working conditions. By judging whether the aging time and the number of aging times have been reached, it is ensured that the actuator is fully aged in multiple cycles to evaluate its long-term performance and reliability. Through the stepping test in the positive and reverse directions, the bidirectional movement of the actuator in actual use is simulated to ensure the comprehensiveness of the test. The entire test process is highly automated, reducing human intervention and improving the efficiency and consistency of the test. Multiple actuators can be tested at the same time to improve the batch processing capacity of the test.

[0131] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention.
