[0032] As can be understood from the above, the door lock test module 2 is connected with the instrument door 101 under test through the clamping piece 11, the controller drives the clamping piece 11 to drive the instrument door 101 under test to reciprocally open and close to simulate the actual working conditions through the cooperation of the driving opening and closing assembly 13 and the transmission wheel 12, so as to test the limit number of uses of the door shaft 103 / door hinge of the instrument door 101; meanwhile, in combination with the door lock test module 2, the positioning assembly 21 in the door lock test module 2 positions the door lock test module 2 at the door lock 102, and then the controller controls the driving unlocking assembly 23 to drive the pressing assembly 22 to unlock the door lock 102, after unlocking, the door opening and closing test module 1 opens and closes the door to simulate the actual working conditions, completes the complete linkage process from unlocking to opening and closing of the instrument door, and repeats the above steps for multiple cycles to realize the durability testing of the instrument door.

[0033] It should be noted that in the embodiment, the controller is a PLC controller, which is a prior art and will not be described here.

[0034] Optionally, in the embodiment, as shown in Figure 1 and Figure 4 , Figure 4 is a structural schematic diagram of the door opening and closing test module 1 in an embodiment. The driving opening and closing assembly 13 includes a driving wheel 131 and a door opening and closing driving member 132, and the driving wheel 131 is in transmission connection with the transmission wheel 12. The door opening and closing driving member 132 is connected with the driving wheel 131 to drive the driving wheel 131 to rotate. Wherein, the door opening and closing driving member 132 is set as a motor, and can also be set as other power devices. In other embodiments, the driving mode of the driving opening and closing assembly 13 to drive the transmission wheel 12 to rotate is not limited to the above or the figure shown, for example, the driving opening and closing assembly 13 can also drive the transmission wheel 12 to rotate through the rack 2213.

[0035] As shown in Figure 4 , in the embodiment, the driving wheel 131 is in gear transmission with the transmission wheel 12, and in other embodiments, the driving wheel 131 can also be in transmission with the transmission wheel 12 through a synchronous belt or a chain.

[0036] Optionally, the diameter of the driving wheel 131 is smaller than the diameter of the transmission wheel 12, so that the lever principle is used to drive the transmission wheel 12 with a larger diameter to rotate by the driving wheel 131 with a smaller diameter, and the required driving force is smaller, which is conducive to reducing the power of the driving motor.

[0037] As shown in Figure 2 and Figure 4 , the clamping piece 11 is provided with a clamping groove 113, and the clamping piece 11 is sleeved on the door 101 of the instrument to be tested through the clamping groove 113, so that the side wall of the clamping groove 113 applies force to the side of the door when the clamping piece 11 is pushed, and then the door is pushed to open or close.

[0038] Optionally, as shown in Figure 4 , the clamping piece 11 includes a first clamping block 111 and a second clamping block 112 arranged oppositely, and the clamping groove 113 is formed between the first clamping block 111 and the second clamping block 112. When the clamping piece 11 is sleeved on the door 101 of the instrument to be tested, the first clamping block 111 and the second clamping block 112 are located on both sides of the door panel, so that the door 101 of the instrument to be tested can be pushed to open or close. In other embodiments, the specific structure of the clamping piece 11 is not limited to the above, as long as the clamping groove 113 is sleeved on both sides of the instrument door 101.

[0039] Preferably, the slot side wall surface of the card slot 113, i.e. the surface of the first and second clamping blocks 111 and 112 interacting with the door, is shaped to match the two side surfaces of the door panel of the instrument door 101. In this way, the door is opened and closed more smoothly, and relative displacement between the clamping member 11 and the instrument door 101 is avoided.

[0053] After the controller is connected to the power supply, the positions of the trigger 143 and the inductive signal generating element 243 are judged first, if the initial position sensor 141 does not induct the trigger 143, the door opening and closing driving part 132 rotates to drive the driving wheel 131 to rotate, so that the trigger 143 moves to the position of the initial position sensor 141, that is, the instrument door 101 to be tested reaches the initial position, and the instrument door 101 to be tested is in the closed state; similarly, if the first inductor 241 does not induct the inductive signal generating element 243, the driving transmission gear 231 rotates to drive the rack 2213 and the inductive signal generating element 243 to move to stop at the first inductor 241, to reach the initial position, and the door lock of the instrument door is in the locked state.

[0054] After the instrument door and the door lock reach the initial position, the main controller controls the automatic test device to be stationary for 10s. Then, the main controller controls the transmission gear 231 to rotate to drive the rack 2213 to move towards the door lock, the pushing piece 221 moves on the guide rail 222 towards the door lock, and the pushing piece 221 moves on the guide rail 222 towards the door lock until the inductive signal generating element 243 moves to the position of triggering the second inductor 242, the transmission gear 231 stops rotating, and the contact 2212 pushes into the door lock slot of the instrument door to complete the unlocking.

[0055] After the door lock 102 is unlocked, the second sensor 242 sends a signal to the controller, and the controller controls the automatic testing device to be stationary for 10 s to avoid errors caused by movement inertia. The controller sends a signal to the door opening and closing drive 132 to start, thereby driving the driving wheel 131 to rotate, and further driving the transmission wheel 12 to rotate, and the transmission wheel 12 drives the clamping piece 11 to rotate, at this time, the instrument door 101 rotates around the axis of the transmission wheel 12 as the center, and the pump door is opened. When the transmission wheel 12 rotates, the trigger 143 connected thereto rotates, and when the instrument door rotates to the specified position, that is, when the stop position sensor 142 senses the trigger 143, the pump door is completely opened, and the instrument door 101 reaches the end position.

[0056] After the instrument door 101 reaches the end position, the controller controls the transmission gear 231 to rotate reversely, drives the rack 2213 to move away from the door lock, and until the first sensor 241 senses the sensing signal generating element 243, the sensing signal generating element 243 reaches the initial position, the transmission gear 231 stops rotating, the door lock button is completely released, and the door lock 102 returns to the initial state.

[0057] After the door lock 102 returns to the initial state, the controller controls the automatic testing device to be stationary for 10 s. After 10 s, the controller sends a signal to the door opening and closing drive 132 (i.e. a DC motor), and the door opening and closing drive 132 drives the driving wheel 131 to rotate clockwise, the transmission gear 231 meshing with the driving wheel 131 rotates counterclockwise, the clamping piece 11 fixed on the transmission gear 231 drives the instrument door 101 to rotate counterclockwise around the axis of the transmission gear 231 as the center, and until the initial position sensor 141 senses the trigger 143, the instrument door 101 is closed, that is, the instrument door reaches the initial position.

[0058] After the above actions are completed, the instrument door and the door lock complete one opening and closing, the controller records the instrument door and the door lock state, and completes one recording period. The controller transmits a signal to the counter to record the opening and closing times of the instrument door and the door lock, respectively, and automatically continues the above steps in a cycle, and after the test requirement times are reached, the power is cut off, and the durability automatic test of the instrument door shaft / hinge and the door lock is completed.
