Description

TECHNICAL FIELD

[0001] The utility model relates to automatic test technical field, concretely relates to full -automatic test equipment of vending cabinet. BACKGROUND

[0002] In today's era of rapid development of automation technology, the automatic test of vending cabinet is crucial to ensure its efficient and stable operation. Traditionally, the test of vending cabinet relies on manual test frame. However, this traditional manual test frame exposes many problems that cannot be ignored.

[0003] First of all, in terms of dynamic characteristic test ability, manual test frame has serious shortcomings. In the actual operation process of vending cabinet, it will face various dynamic changes, such as dynamic response of mechanical parts caused by frequent goods access operation. Manual test frame is difficult to simulate these complex and rapid dynamic scenarios, and cannot accurately evaluate the performance of vending cabinet under real dynamic conditions, which makes vending cabinet frequently malfunction after being put into actual use due to its inability to adapt to dynamic changes.

[0004] Secondly, in terms of parameter control accuracy, manual test frame has obvious defects. During the test, accurate control of key parameters such as temperature, humidity, motor speed, etc. is directly related to the accuracy of performance evaluation of vending cabinet. Manual test frame often relies on manual operation and adjustment, and it is difficult to achieve high-precision control of parameters, which is prone to large error fluctuations. The lack of parameter control accuracy makes the test results unable to truly reflect the actual performance of vending cabinet, which may lead to misjudgment of product quality and affect the market competitiveness of products.

[0005] Thirdly, in terms of data collection and analysis, manual test frame has significant shortcomings. During the test, a large amount of data related to the performance of vending cabinet needs to be collected and analyzed in depth to fully understand its running status and performance advantages and disadvantages. Manual test frame's data collection often relies on manual recording, which is inefficient and prone to errors, and it is difficult to achieve real-time and accurate collection of multi-parameter and high-frequency data. At the same time, in the later stage of data analysis, manual analysis not only consumes time and effort, but also is limited by human factors, making it difficult to use complex and efficient data analysis algorithms and models, and unable to fully tap the information hidden behind the data, which is not conducive to the comprehensive and in-depth evaluation and improvement of the performance of vending cabinet.

[0006] In summary, the shortcomings of traditional manual test frame in dynamic characteristic test ability, parameter control accuracy and data collection and analysis in the automatic test of vending cabinet, an entirely new and more efficient and accurate test scheme is urgently needed to solve the problem, in order to meet the needs of modern vending cabinet production and quality detection.

[0040] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0041] In today's era of rapid development of automation technology, automatic testing of vending cabinets is crucial to ensure their efficient and stable operation. Traditionally, the testing of vending cabinets relies on manual test stands. However, this traditional manual test stand exposes many problems that cannot be ignored.

[0042] Firstly, in terms of dynamic performance testing capability, manual test stands have serious shortcomings. In actual operation, vending cabinets will face various dynamic changes, such as dynamic response of mechanical parts caused by frequent goods access operations. Manual test stands are difficult to simulate these complex and rapidly changing dynamic scenarios, and cannot accurately evaluate the performance of vending cabinets under real dynamic conditions, which makes vending cabinets frequently malfunction after being put into actual use due to their inability to adapt to dynamic changes.

[0043] Secondly, in terms of parameter control accuracy, the manual test stand has obvious defects. During the test process, the accurate control of key parameters such as temperature, humidity, motor speed, etc. is directly related to the accuracy of the performance evaluation of the vending cabinet. The manual test stand often relies on manual operation and adjustment, and it is difficult to achieve high-precision control of parameters, and it is easy to produce large error fluctuations. The lack of parameter control accuracy makes the test results unable to truly reflect the actual performance of the vending cabinet, which may lead to misjudgment of product quality and affect the market competitiveness of the product.

[0044] Furthermore, in terms of data collection and analysis, the manual test stand has significant shortcomings. During the test process, a large amount of data related to the performance of the vending cabinet needs to be collected and analyzed in depth to fully understand its running status and performance advantages and disadvantages. The data collection of the manual test stand often relies on manual recording, which is low in efficiency and prone to errors, and it is difficult to achieve real-time and accurate collection of multi-parameter and high-frequency data. At the same time, in the later stage of data analysis, manual analysis not only consumes time and effort, but also is limited by human factors, making it difficult to use complex and efficient data analysis algorithms and models, and unable to fully tap the information hidden behind the data, which is not conducive to the comprehensive and in-depth evaluation and improvement of the performance of the vending cabinet.

[0045] In summary, the traditional manual test stand has deficiencies in dynamic characteristic test capability, parameter control accuracy, and data collection and analysis in the automatic test of the vending cabinet, and a new and more efficient and accurate test scheme is urgently needed to solve the problem to meet the needs of modern vending cabinet production and quality detection.

[0046] The embodiments of the present application will be described below in combination with Figures 1 to 7 .

[0047] According to the embodiments of the present application, on the one hand, a vending cabinet full-automatic test equipment is provided, which comprises a frame 1, a limiting piece 2, a reset piece 3, a lifting frame 4, a driving device 5 and a control assembly. The lower side of the frame 1 is provided with a placing cavity, and the placing cavity is suitable for placing a cabinet lock 7. The limiting piece 2 is connected with the frame 1 and is arranged on the upper side of the placing cavity. The limiting piece 2 is suitable for slidingly placing a lock catch 8. The reset piece 3 is arranged on the limiting piece 2, and the reset piece 3 is suitable for abutting against the lock catch 8. The reset piece 3 has a biasing force for forcing the lock catch 8 to remain on the outside of the cabinet lock 7. The lifting frame 4 is movably arranged in the frame 1, and the lifting frame 4 is arranged on the upper side of the reset piece 3. The driving device 5 is fixed on the frame 1. The driving device 5 is connected with the lifting frame 4, and the driving device 5 is configured to drive the lifting frame 4 to move downward to push the lock catch 8 to overcome the biasing force of the reset piece 3 and enter the inside of the cabinet lock 7, or the driving device 5 is configured to drive the lifting frame 4 to move upward to separate from the lock catch 8. The control assembly is electrically connected with the driving device 5 and the cabinet lock 7 to control the driving device 5 and the cabinet lock 7 to generate corresponding actions.

[0048] During the test process, when the control assembly issues a test instruction, the driving device 5 drives the lifting frame 4 to move downward, pushes the lock catch 8 to overcome the biasing force of the reset member 3 by precise force control, so as to enter the inside of the cabinet lock 7 at a speed and force that meet the actual use conditions, the control assembly controls the driving device 5 to stop running, at the same time, the control assembly controls the cabinet lock 7 to close, and after about 2S, the control assembly controls the driving device 5 to drive the lifting frame 4 to move upward, when the lifting frame 4 reaches the predetermined position, the control assembly issues an instruction to make the driving device 5 stop running. Then, after about 1S, the control assembly controls the cabinet lock 7 to be opened one by one, and the reset member 3 pushes the lock catch 8 back to the initial position in turn, so as to complete a test cycle, and after about 2S, the next cycle is carried out. The whole test process does not need manual intervention, realizes fully automatic operation, greatly improves the test efficiency, avoids errors and uncertainties caused by manual operation, and significantly improves the accuracy and reliability of the test results. Compared with the traditional manual test frame, the vending cabinet full-automatic test equipment has significant advantages in dynamic characteristic test ability, parameter control precision, data acquisition and analysis and the like. It can more truly and comprehensively simulate various working conditions of the vending cabinet in actual use, tests the cabinet lock 7 from multiple angles and in all directions, effectively solves many problems existing in the traditional test mode, provides strong technical support for quality detection and performance optimization of the vending cabinet, and has wide market application prospect and popularization value.

[0049] Specifically, the frame 1 is the basic support structure of the whole equipment, and the lower side part is provided with a special placing cavity, which is designed in a modular manner and can adapt to cabinet locks 7 of various models, so that the cabinet lock 7 will not be deviated or shaken during the test process, laying a foundation for accurate testing.

[0050] Specifically, as shown in the structure shown in the structure, Figures 3 to 6 As shown, the width of the lifting frame 4 is smaller than the distance between the two limiting members 2 on the lock catch 8, so that the lifting frame 4 will not be interfered by the limiting members 2 beside the lock catch 8 during the descending process. Figure 7

[0051] As shown in the structure shown in the structure, Figure 4 Figure 4 ​​Only one reset member 3 is shown for illustration. The reset member 3 is a spring, which is sleeved on the surface of the limiting member 2, and the upper end of the spring is in contact with the lower side of the lock catch 8, and the lower end of the spring is in abutment on the above-mentioned plate member of the frame 1. It can be understood that when the lifting frame 4 does not press down the lock catch 8, the lock catch 8 can always be on the upper side of the cabinet lock 7 under the action of the reset member 3, and when the lifting frame 4 is pressed down, it can enter the inside of the cabinet lock 7. At the same time, when the cabinet lock 7 is opened after the lifting frame 4 is lifted, the lock catch 8 can be reset under the biasing force of the reset member 3 to leave the inside of the cabinet lock 7 for the next test.

[0052] As shown in Figure 3 , Figure 5 and Figure 7 , the lifting frame 4 is plate-shaped, and the two ends of the lifting frame 4 are provided with notches, and the lifting frame 4 is slidably connected with the upper side plate of the frame 1 through the notches, and the side edge of the frame 1 can also limit the lifting frame 4, so that it can only move upward or downward. A row of lock catches 8 and a cabinet lock 7 are arranged on the lower side of the lifting frame 4, and when the lifting frame 4 is pressed down, it can uniformly push the row of cabinet locks 7 on the lower side. As shown in Figure 7 , the lifting frame 4 is provided with two.

[0053] The control assembly is electrically connected with the driving device 5 and the cabinet lock 7. It is developed based on an embedded control system, and integrates a high-performance microprocessor, a rich sensor interface and a communication module. The control assembly can accurately control the action of the driving device 5 through a preset test program, including the lifting speed, force and movement trajectory of the lifting frame 4. At the same time, it can also interact with the cabinet lock 7, and real-time monitor the working state of the cabinet lock 7, such as the extension of the lock tongue, the rotation angle of the lock cylinder, the current and voltage in the lock body and other parameters. The control assembly uses data analysis algorithm and fault diagnosis model to analyze and process the collected data in real time. The control assembly acts on the control of the operation of the above-mentioned structure by using the preset program, and it can be adaptively improved by using the existing program.

[0054] In one embodiment, the driving device 5 has a leveling mode, in which the lifting frame 4 is leveled by the driving device 5. Under long-term use, the accumulation of deviation of the driving device 5 may cause the lifting frame 4 to tilt, which makes the lifting frame 4 easily interfere with the frame 1 during movement, or it cannot effectively push all the lock catches 8 on the lower side of the lifting frame 4 into the cabinet lock 7. Therefore, in this embodiment, the driving device 5 is provided with a leveling mode, and when the lifting frame 4 tilts, the control assembly controls the driving device 5 to enter the leveling mode, and in the leveling mode, the lifting frame 4 is leveled by the driving device 5.

[0055] In one embodiment, the drive device 5 includes several drive components, all of which are connected to the lifting frame 4. In leveling mode, at least one drive component is activated individually, or multiple drive components are activated sequentially in a preset order, driving the lifting frame 4 to level. Specifically, the drive components employ a design of high-performance servo motors combined with precision lead screw transmission mechanisms. Each drive component independently controls one support point of the lifting frame 4, forming a distributed drive system. This structural design enables the lifting frame 4 to achieve multi-point, precise height adjustment during leveling.

[0056] by Figure 2 and Figure 7 Taking the structure shown as an example, in the initial stage of leveling, high-precision tilt sensors distributed on both sides of the lifting frame 4 collect tilt data in real time and transmit it to the control component. The control component analyzes the data based on a preset leveling algorithm. When tilting of the lifting frame 4 is detected, it determines the driving component to be activated based on the tilt angle and direction. During adjustment, the control component prioritizes activating the single driving component closest to the tilt direction. After receiving the control command, the servo motor of this driving component operates at a constant low speed, slowly adjusting the height of the corresponding support point through the screw transmission mechanism. At the same time, the tilt sensors continuously provide data feedback, and the control component dynamically adjusts the operating parameters of the driving component based on the real-time data until the lifting frame 4 reaches a horizontal state. Alternatively, when driving components are installed at all four corners and the center of the lifting frame 4, if the tilt angle of the lifting frame 4 is large or there is a complex multi-directional tilt, the control component will activate multiple driving components, activating them one by one in a preset order. For example, if the lifting frame 4 is diagonally tilted, the control component first activates the driving components located at both ends of the tilt direction, raising or lowering the corresponding points at the same rate to initially reduce the tilt angle. Subsequently, based on feedback from the tilt sensor, the control component sequentially activates other drive components to fine-tune the lifting frame 4. During this process, the drive components achieve precise coordination through the control component. The activation timing, operating speed, and stroke of each drive component are rigorously calculated to ensure a smooth transition of the lifting frame 4 during leveling, avoiding structural stress concentration or equipment vibration caused by excessive local adjustment.

[0057] In one embodiment, the drive components on the lifting frame 4 are arranged along the same straight line. For example... Figure 2 As shown, the drive device 5 includes a first drive member 51, a second drive member 52, a third drive member 53, and a fourth drive member 54. The first drive member 51 and the third drive member 53 act on a lifting frame 4, and the second drive member 52 and the fourth drive member 54 act on a lifting frame 4. The first drive member 51 and the third drive member 53 are on the same straight line, and the second drive member 52 and the fourth drive member 54 are on the same straight line. This allows the drive members on the same straight line to drive only one end of the lifting frame 4 to move up or down when leveling the lifting frame 4.

[0058] In one embodiment, the driving device 5 further comprises several lead screws; one end of any lead screw is connected to the lifting frame 4 through a threaded hole on the lifting frame 4, and the other end of the lead screw is coupled with and driven by the driving member to rotate. During the leveling work, when the driving member receives the instruction from the control assembly to start rotating, the lead screw coupled therewith rotates synchronously. Since the lead screw is connected to the lifting frame 4 through threads, according to the screw transmission principle, the rotating motion of the lead screw is converted into the linear motion of the lifting frame 4 along the axis direction of the lead screw. For example, when the driving member rotates clockwise, the lead screw drives the lifting frame 4 to move upward along the axis of the lead screw; conversely, when the driving member rotates counterclockwise, the lifting frame 4 moves downward. By controlling the rotating direction, rotating speed and rotating number of the driving member, the lifting height and speed of the lifting frame 4 can be accurately controlled.

[0059] In one embodiment, the control assembly comprises a relay 61 and a counter 62, the relay 61 is connected to the frame 1, and the relay 61 is electrically connected with the driving device 5 and the cabinet lock 7; the counter 62 is connected to the frame 1, and the counter 62 is electrically connected with the relay 61. The relay 61 and the counter 62 as the core components of the control assembly bear the important functions of signal transmission, logic control and data statistics, and work with the driving device 5, the cabinet lock 7 and the like to ensure the stable and efficient operation of the full-automatic testing equipment for the vending cabinet. All of them are existing components, which are directly used in the embodiment.

[0060] In one embodiment, as shown in Figure 1 the control assembly further comprises an upper side optocoupler 63 and a lower side optocoupler 64, the upper side optocoupler 63 is fixed on the upper side of the frame 1; the upper side optocoupler 63 is electrically connected with the relay 61, and the upper side optocoupler 63 is adapted to detect the position in the lifting process of the lifting frame 4; the lower side optocoupler 64 is fixed on the inner side of the frame 1, the lower side optocoupler 64 is electrically connected with the relay 61, and the lower side optocoupler 64 is adapted to detect the position in the lowering process of the lifting frame 4. The upper side optocoupler 63 and the lower side optocoupler 64 as the key elements for realizing the accurate position detection in the control assembly work with the relay 61 through the photoelectric induction principle to provide real-time and accurate feedback signals for the motion control of the lifting frame 4.

[0061] During the test, when the control assembly sends a test instruction, the driving device 5 drives the lifting frame 4 to move downwards, pushes the lock catch 8 to overcome the biasing force of the reset member 3 by precise force control, so as to enter the cabinet lock 7 at a speed and force in line with the actual use condition, the lifting frame 4 reaches the signal area of the lower light coupling 64, the control assembly controls the driving device 5 to stop running, and simultaneously controls the cabinet lock 7 to close.

[0062] In an embodiment, a buffer member is arranged on the frame 1, and the buffer member is adapted to abut against the lower side of the lock catch 8. Figure 4 As shown in the figure, the side edge of the lock catch 8 is located on the upper side of the middle plate member of the frame 1, and during the process that the driving device 5 drives the lifting frame 4 to move downwards and the lifting frame 4 pushes down the lock catch 8 to move downwards, the side edge of the lock catch 8 will hit the upper side of the middle plate member of the frame 1 to generate noise, therefore, in the embodiment, a silica gel buffer member is arranged on the upper side of the plate member of the frame 1 to reduce the sound generated by the side edge of the lock catch 8 hitting the middle plate member of the frame 1.

[0063] According to the embodiment of the utility model, on the other hand, a full-automatic vending cabinet test method is also provided, which comprises the following steps:

[0064] The driving device 5 is started, the driving device 5 drives the lifting frame 4 to move downwards, the lifting frame 4 abuts against the upper side of the lock catch 8, the lifting frame 4 continues to push the lock catch 8 to move downwards along the limiting member 2 and compresses the reset member 3, until the lock catch 8 enters the cabinet lock 7;

[0065] The control assembly controls the cabinet lock 7 to close;

[0066] After 2S, the driving device 5 is started, the driving device 5 drives the lifting frame 4 to move upwards to a preset height and stop;

[0067] After 1S, the control assembly controls the cabinet lock 7 to open, and the lock catch 8 rises to leave the inside of the cabinet lock 7 under the action of the reset member 3;

[0068] After 2S, the above steps are repeated.

[0069] The vending machine full-automatic test method, since the vending machine full-automatic test equipment is adopted, the whole test process does not need manual intervention, full-automatic operation is realized, the test efficiency is greatly improved, errors and uncertainties brought by manual operation are avoided, and the accuracy and reliability of the test result are obviously improved. Compared with the traditional manual test frame, the vending machine full-automatic test equipment has obvious advantages in dynamic characteristic test capability, parameter control precision, data acquisition and analysis and the like. It can more truly and comprehensively simulate various working conditions of the vending machine in actual use, tests the cabinet lock 7 from multiple angles and in all directions, effectively solves many problems existing in the traditional test mode, provides strong technical support for quality detection and performance optimization of the vending machine, and has wide market application prospect and popularization value.

[0070] In one embodiment, when the driving device 5 is started, the driving device 5 drives the lifting frame 4 to move downward, the lifting frame 4 abuts against the upper side of the lock catch 8, the lifting frame 4 continues to push the lock catch 8 to move downward along the limiting piece 2 and compress the reset piece 3, until the lock catch 8 enters the inside of the cabinet lock 7, and the driving device 5 further comprises that, among the plurality of driving pieces in the driving device 5, at least one driving piece is independently started or a plurality of driving pieces are started one by one in a preset order, and the lifting frame 4 is leveled.

[0071] In the long-term use, the accumulation of the deviation of the driving device 5 can cause the lifting frame 4 to tilt, which makes the lifting frame 4 easily interfere with the frame 1 during movement, or it cannot effectively push all the locks 8 on the lower side of the lifting frame 4 into the cabinet lock 7. In the initial leveling stage, the high-precision inclination sensors distributed on both sides of the lifting frame 4 collect the inclination data in real time and transmit them to the control assembly. The control assembly analyzes the data based on the preset leveling algorithm, and when it detects that the lifting frame 4 is tilted, it will determine the starting driving part according to the tilt angle and direction. When adjusting, the control assembly will preferentially select the single driving part closest to the tilt direction to start alone. After receiving the control instruction, the servo motor operates at a constant low speed, slowly adjusts the height of the corresponding support point through the screw transmission mechanism, and the inclination sensor continuously feeds back the data. The control assembly dynamically adjusts the operating parameters of the driving part according to the real-time data until the lifting frame 4 reaches the horizontal state. Alternatively, when the lifting frame 4 is provided with driving parts at the four corners and the center position, when the lifting frame 4 has a large tilt angle or a complex multi-direction tilt, the control assembly will start multiple driving parts and start them one by one according to the preset order. For example, if the lifting frame 4 presents a diagonal tilt state, the control assembly first starts the driving parts located at both ends of the tilt direction to raise or lower the corresponding point at the same rate, thereby initially reducing the tilt angle. Subsequently, according to the feedback of the inclination sensor, the control assembly sequentially starts other driving parts to fine-tune the lifting frame 4. In this process, the driving parts are precisely coordinated through the control assembly, and the starting time, operating speed and stroke of each driving part are strictly calculated to ensure smooth transition of the lifting frame 4 during leveling and avoid structural stress concentration or equipment vibration caused by excessive local adjustment amplitude.

[0072] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
