[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] Please refer to Figures 1-4 ;

[0025] The linear module test stand of the present invention can not only test the lifespan of multiple modules 2 to be tested at the same time, but also issue an alarm after a module 2 to be tested fails. Furthermore, the present invention can also provide the operator with the number of short-term failures that occurred in each module 2 to be tested before it cannot be used or a long-term failure occurs. It is worth noting that in this embodiment, a long-term failure refers to a failure that persists and cannot slide in both horizontal directions, requiring more detailed troubleshooting and repair, or three short-term failures; a short-term failure refers to a one-time failure caused by temporary factors, such as a short-term jam, which can be restored to normal through further testing.

[0026] A linear module test stand with a reminder function includes a frame 1, and a plurality of test stations are provided on the frame 1. In this embodiment, four test stations are provided on the frame 1 to be able to measure multiple modules 2 to be tested at the same time. The frame 1 includes a vertically placed module fixing plate 11 and support plates 12 located on both sides of the module fixing plate 11. In this embodiment, the support plates 12 are preferably triangular prism-shaped so that the frame 1 can be placed more stably on the workbench. The two support plates 12 are also provided with two reinforcing ribs 13, and the two reinforcing ribs 13 are respectively located on both sides of the module fixing plate 11. In order to further improve the stability of the frame 1, four L-shaped plates 14 are provided at the bottom end of the frame 1. The side walls of the L-shaped plate 14 are fixedly connected to the support plate 12, and the bottom end of the L-shaped plate 14 is detachably connected to the workbench; the four test stations are respectively located on both sides of the two support plates 12 away from the module fixing plate 11 and on both sides of the module fixing plate 11; the modules 2 to be tested are all placed vertically on the test stations. In one embodiment, a driving device for driving the moving end of the module 2 to be tested is provided on the test station; and the driving device is preferably a driving motor, which is mounted on the frame 1, and the driving motor can be rotatably connected to the module 2 to be tested; in this embodiment, the module 2 to be tested includes a driving motor, so that the module 2 to be tested can be detachably placed on the test station.

[0027] The frame 1 is electrically connected with a control module, a counting module and a reminder module. When the module to be tested is installed on the workstation to be tested, the control module can control the driving device of the module to be tested 2, that is, the control module can control the opening and closing of the driving motor. At the same time, the control module can count the speed of the driving motor. The life of the module to be tested 2 can be calculated for the first time through the speed of the driving motor and the number of turns of the driving motor required for the mobile end of the module to be tested 2 to move back and forth. However, considering that the module to be tested 2 may have a short-term fault during actual use, a counting module is also used in this embodiment to more accurately calculate the number of movements of the module to be tested 2. Specifically, a first positioning plate 3 and a second positioning plate 4 are fixedly provided on the frame 1. The first positioning plate 3 and the second positioning plate 4 are respectively located on both sides of the lower end of the module to be tested 2, that is, the first positioning plate 3 and the second positioning plate 4 are respectively located on both sides of the lower end of the module to be tested 2, that is, the first positioning plate 3 and the second positioning plate 4 are respectively located on both sides of the lower end of the module to be tested Plate 4 is located on the side away from the drive motor, and a laser lamp is provided on the side of the first positioning plate 3 facing the second positioning plate 4 to emit light. A light sensor is provided on the side of the second positioning plate 4 facing the first positioning plate 3, that is, the light emitted by the laser lamp can be irradiated and received by the light sensor. The light sensor is electrically connected to the counting module, and the counting module can count the number of times the light sensor is interrupted. When the mobile end of the module to be tested 2 moves to the bottom end, the mobile end of the module to be tested 2 interferes with the light emitted by the laser lamp and is received by the light sensor. At this time, the light sensor can send a signal to the counting module. A counter is provided in the counting module, and the counter automatically increases by one, representing a successful test of the mobile end of the module to be tested 2. At the same time, the counter is electrically connected to the control module to transmit the result that the counter has successfully completed a test to the control module.

[0028] Specifically, the control module includes a microprocessor, which is electrically connected to the counter. The microprocessor is also bidirectionally connected to the reminder module. The reminder module includes a buzzer, several timers, and several prompt lights 5 corresponding to the timers. In this embodiment, the number of timers is preferably three, and accordingly, the number of prompt lights 5 is three. The timers correspond to the prompt lights 5 one-to-one, and the prompt lights 5 are electrically connected to the timers. The circular array of prompt lights 5 is arranged on the surface of the control button 6 of the rack 1; the microprocessor is electrically connected to the buzzer, and bidirectionally electrically connected to the three timers. In this embodiment, the time interval between the timers is equal to the time it takes for the mobile end of the module to be tested 2 to move once.

[0029] During use, the operator first fixedly connects the bottom end of the L-shaped plate 14 of the frame 1 to the workbench, installs the module 2 to be tested on the test station of the frame 1, and electrically connects the drive motor of the module 2 to be tested to the microprocessor. Then, the control button 6 is pressed, so that the drive motor drives the moving end of the module 2 to be tested to move, and the moving end of the module 2 to be tested moves in a circular motion under the drive of the drive motor. When the moving end of the module 2 to be tested passes through the lowest end, it blocks the laser light from irradiating on the light sensor, interrupts the light signal received by the light sensor once, the counter can receive the interrupted signal of the light sensor and increment the counter by one, and at the same time the counter can transmit the signal of incrementing the counter by one to the microprocessor. The microprocessor receives the signal of incrementing the counter by one and transmits it to the timer, so that the timer restarts timing;

[0030] If the first short-term failure occurs and the moving end of the module 2 to be tested does not reach the lowest end, at this time the counter does not receive the signal and thus does not transmit the signal to the microprocessor. The microprocessor does not receive the signal. When Timer 1 does not receive the signal within the specified time and waits until the timing time exceeds the time for the moving end of the module 2 to be tested to make a round trip, Timer 1 transmits the signal to the microprocessor. After receiving the signal, the microprocessor will transmit the signal to the buzzer for a short alarm reminder. At the same time, the indicator light 5 corresponding to Timer 1 will be constantly on; this Timer 1 stops working and Timer 2 starts working; if the second short-term failure occurs and the moving end of the module 2 to be tested does not reach the lowest end, at this time the counter does not receive the signal and thus does not transmit the signal to the microprocessor. The microprocessor does not receive the signal. When Timer 2 does not receive the signal within the specified time and waits until the timing time exceeds the time for the moving end of the module 2 to be tested to make a round trip, Timer 2 transmits the signal to the microprocessor, and at the same time the microprocessor transmits the signal to the buzzer for a short alarm reminder and makes the indicator light 5 corresponding to Timer 2 constantly on; this Timer 2 stops working and Timer 3 starts working; if the third short-term failure occurs, at this time the three short-term failures are regarded as long-term failures. When Timer 3 does not receive the signal within the specified time and waits until the timing time exceeds the time for the moving end of the module 2 to be tested to make a round trip, Timer 3 transmits the signal to the microprocessor. At this time, the microprocessor will control the lifting light corresponding to Timer 3 to be constantly on and make the buzzer sound continuously, and control the drive motor to stop rotating.

[0031] If the first short-term failure is a long-term failure, that is, the drive motor cannot rotate forward or backward, or the life of the module 2 to be tested has expired and the moving end of the module 2 to be tested cannot move, the microprocessor will directly control the buzzer to sound continuously. At the same time, the counter will count the service life of the module 2 to be tested; it should be noted that the error between the value of this counter and the value of the movement of the moving end of the module 2 to be tested calculated according to the number of turns of the drive motor should be less than one time.
