It should also be understood that the terms "include," "comprising," "having," and the like specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof. Furthermore, the term "and / or" as used in this specification includes any and all combinations of the relevant listed items.

[0045] In an exemplary embodiment, referring to Figure 1 , provides a micro switch calibration system, which includes a first test station 1, a second test station 2 and a test host (not shown in the figure); wherein, automatic calibration software is burned into the measurement and control host to realize various functions of the measurement and control host; the measurement and control host can be connected to both the first test station 1 and the second test station 2.

[0046] The first testing station 1 includes a plurality of first checking tables 11 and a plurality of first transmission mechanisms 12 .

[0047] Each first calibration platform 11 is used to carry a first microswitch 13 to be tested and to provide power to the carried first microswitch 13. Each first calibration platform 11 is used to carry one first microswitch 13 to be tested. The first microswitch 13 to be tested can be fixed to the carrying surface of the first calibration platform 11. For example, the first microswitch 13 to be tested can be fixed by a fixing fixture on the carrying surface of the first calibration platform 11. The first calibration platform 11 can be electrically connected to the carried first microswitch 13 to be tested. For example, the first calibration platform 11 can be electrically connected to the carried first microswitch 13 to be tested via a wire, so that the first microswitch 13 to be tested is connected in series to the power supply circuit.

[0048] Different types of first transmission mechanisms 12 are configured to correspond to different types of first microswitches 13 to be tested. These different types of first transmission mechanisms 12 have different specific structures. The first microswitches 13 to be tested may be, for example, push-type or rotary. Different types of first microswitches 13 to be tested are matched with different types of first transmission mechanisms 12, enabling the different types of first transmission mechanisms 12 to actuate the actuating reeds of the different types of first microswitches 13 to be tested.

[0049] The measurement and control host is used to control each first transmission mechanism 12 to touch the action reed of the corresponding first microswitch 13 to be tested according to the verification instruction, and verify according to the first opening and closing detection signal of the first microswitch 13 to be tested to obtain the mechanical operation test result of the first microswitch 13 to be tested, wherein the mechanical operation test result includes the mechanical operation test being qualified or the mechanical operation test being unqualified.

[0050] For example, the measurement and control host obtains the first opening and closing detection signal of the first microswitch 13 to be tested, and when the first opening and closing detection signal meets the first preset condition, determines that the mechanical operation test of the first microswitch 13 to be tested is qualified; when the first opening and closing detection signal does not meet the first preset condition, determines that the mechanical operation test of the first microswitch 13 to be tested is unqualified. For example, the first preset condition may include: when the first microswitch 13 to be tested continuously performs a preset number of closing-opening operation cycles, the first opening and closing detection signal obtained each time is the same as the preset signal. The measurement and control host can independently control each first transmission mechanism 12 to independently perform mechanical operation verification on the first microswitch 13 to be tested on each first verification station 11.

[0051] The second testing station 2 includes a plurality of second testing tables 3 and a second transmission mechanism 4 .

[0052] Each second calibration platform 3 is used to carry a second microswitch 21 to be tested and to provide power to the carried second microswitch 21. Each second calibration platform 3 is used to carry one second microswitch 21 to be tested. The second microswitch 21 to be tested can be fixed to the carrying surface of the second calibration platform 3. For example, the second microswitch 21 to be tested can be fixed by a fixing fixture on the carrying surface of the second calibration platform 3. The second calibration platform 3 can be electrically connected to the carried second microswitch 21 to be tested. For example, the second calibration platform 3 can be electrically connected to the carried first microswitch 13 to be tested via a wire, so that the second microswitch 21 to be tested is connected in series to the power supply circuit.

[0053] The second transmission mechanism 4 is used to be set corresponding to each second microswitch to be tested 21. Among the multiple second verification tables 3 of the second test station 2, the types of the second microswitches 21 to be tested carried by at least two second verification tables 3 are the same or different. The type of the second microswitch to be tested 21 is, for example but not limited to, a press-type second microswitch to be tested 211 or a rotary second microswitch to be tested 212. The specific structure of the second transmission mechanism 4 can be compatible with any type of second microswitch to be tested 21, so that the action reed of each second microswitch to be tested 21 can be touched separately by the second transmission mechanism 4. Since the second transmission mechanism 4 can touch the action reed of each second microswitch to be tested 21 for a preset number of times in the same time period, the second test station 2 of the embodiment of the present application can perform mechanical life verification on the second microswitches to be tested 21 in batches in the same time period.

[0054] The measurement and control host is used to control the second transmission mechanism 4 to trigger the action reed of each second microswitch 21 to be tested according to the verification instruction, and verify according to the second opening and closing detection signal of the second microswitch 21 to be tested to obtain the mechanical life test result of the second microswitch 21 to be tested, wherein the mechanical life test result includes the mechanical life test passing or the mechanical life test failing.

[0055] For example, the measurement and control host computer respectively obtains the second opening and closing detection signal of each second microswitch to be tested 21, and determines that the mechanical life test of the second microswitch to be tested 21 is qualified when the second opening and closing detection signal satisfies a second preset condition; and determines that the mechanical life test of the second microswitch to be tested 21 is unqualified when the second opening and closing detection signal does not satisfy the second preset condition. For example, the second preset condition may include: after the second microswitch to be tested 21 continuously performs a preset number of closing-opening operation cycles, the obtained second opening and closing detection signal is the same as the preset signal.

[0056] The above-mentioned microswitch verification system can, in the first test station, determine whether a mechanical operation test of a first microswitch to be tested is qualified or unqualified, thereby realizing the verification and evaluation of the mechanical operation reliability performance of the microswitch; and, in the second test station, can determine whether a mechanical life test of a second microswitch to be tested is qualified or unqualified, thereby realizing the verification and evaluation of the mechanical life reliability performance of the microswitch.

[0057] In an exemplary embodiment, the plurality of first transmission mechanisms 12 of the first test station 1 include at least one first transmission mechanism 121 of a first type. Figure 2The first transmission mechanism 121 of the first type includes a motor and a retractable contact 7. The retractable contact 7 is connected to the motor and positioned parallel to the support surface of the first calibration platform 11 between the motor and the actuating reed of the first push-type microswitch to be tested 131. A measurement and control host is connected to the motor and is configured to drive the motor according to calibration instructions, causing the motor to cause the retractable contact 7 to extend and retract, extending until it actuates the actuating reed of the first push-type microswitch to be tested 131. The motor is, for example, but not limited to, an integrated servo motor.

[0058] In this embodiment, the first type of the first transmission mechanism 121 includes a motor and a telescopic contact 7 , so that the first type of the first transmission mechanism 121 has a simple structure, low cost, and is easy to implement.

[0059] In an exemplary embodiment, the plurality of first transmission mechanisms 12 of the first test station 1 include at least one first transmission mechanism 122 of the second type. Figure 3 The second type of first transmission mechanism 122 includes a motor and a raised contact 8. The raised contact 8 is connected to the motor and positioned perpendicular to the support surface of the first calibration platform 11 between the motor and the actuating reed of the first rotary microswitch 132 to be tested. A measurement and control host is connected to the motor and is configured to drive the motor according to calibration instructions, causing the motor to rotate the raised contact 8 and actuate the actuating reed of the first rotary microswitch 132 to be tested. The motor may be, for example, but not limited to, an integrated servo motor.

[0060] In this embodiment, the second type of first transmission mechanism 122 includes a motor and a raised contact 8, so that the second type of first transmission mechanism 122 has a simple structure, low cost, and is easy to implement.

[0061] In an exemplary embodiment, referring to Figure 3 The raised contact 8 includes a rotating platform 8-1, a step portion 8-3 and two raised columns 8-2; the rotating platform 8-1 is connected to the motor; the side wall of the step portion 8-3 is mechanically connected to the side wall of the rotating platform 8-1, and the surface of the step portion 8-3 facing away from the motor and the surface of the rotating platform 8-1 facing away from the motor are located in the same horizontal plane; the two raised columns 8-2 are uprightly arranged on the surface of the step portion 8-3 facing away from the motor; wherein, reference Figure 4 The surface of the rotating table 8-1 facing away from the motor is used to carry the first rotary micro switch to be tested 132, and the space between the two raised columns 8-2 is used to place the action reed of the first rotary micro switch to be tested 132.

[0062] In this embodiment, the raised contact 8 includes a rotating platform 8-1, a step portion 8-3 and two raised columns 8-2, which further makes the second type of first transmission mechanism 122 simple in structure, low in cost and easy to implement.

[0063] In an exemplary embodiment, referring to Figure 1 In the second test station 2, multiple second calibration tables 3 are sequentially arranged around a second transmission mechanism 4. The second transmission mechanism 4 includes a motor and a rotary contact. The rotary contact is connected to the motor and is arranged opposite the actuating reed of each second microswitch 21 to be tested in a direction parallel to the supporting surface of the second calibration table 3. A measurement and control host is connected to the motor and is configured to drive the motor according to calibration instructions, so that the motor drives the rotary contact to rotate and sequentially actuate the actuating reed of each second microswitch 21 to be tested a preset number of times.

[0064] In this embodiment, mechanical life tests can be performed on a plurality of second micro switches 21 to be tested at the same time, which is conducive to batch testing and improves test efficiency.

[0065] In an exemplary embodiment, the measurement and control host is also used to determine that the mechanical life test of the second microswitch 21 to be tested has passed when the second opening and closing detection signals of the second microswitch 21 to be tested with a preset number of touches all meet the second preset conditions.

[0066] Exemplarily, a second transmission mechanism 4 is provided at the center of the second test station 2. The rotary contact rotates 360 degrees under the control of the motor to sequentially trigger the second micro switch 21 to be tested on each second calibration station 3, thereby achieving simultaneous mechanical life verification of each second micro switch 21 to be tested. The motor is located below the rotary contact, and the motor can be an integrated servo motor. In the mechanical life test, a mechanical operation test is performed before and after the mechanical life and after each series of 1000 closing-opening operation cycles. If the second closing-opening detection signal indicates correctly, it is determined that the mechanical life test of the second micro switch 21 to be tested is qualified. If the indication is incorrect, it is determined that the mechanical life test of the second micro switch 21 to be tested is unqualified. For products with a mechanical life of 5000 times or more, the number of mechanical operations is uniformly performed as 5000 times.

[0067] Among them, the automatic calibration software in the measurement and control host realizes automatic control of the second transmission mechanism through settings, touches the action reed of the microswitch under test in a controllable manner, triggers the detection signal of the microswitch, and receives the detection signal for analysis and judgment, thereby realizing automatic testing of the mechanical life test of the microswitch.

[0068] In an exemplary embodiment, the measurement and control host is also used to determine that the mechanical operation test of the first microswitch 13 to be tested is qualified when the reaction time of the first opening and closing detection signal of the first microswitch 13 to be tested is within a first preset range and the effective stroke is within a second preset range; wherein the reaction time is the time between the moment when the first transmission mechanism 12 just touches the action reed of the first microswitch 13 to be tested and the moment when the measurement and control host obtains the first opening and closing detection signal; the effective stroke is the stroke length of the first transmission mechanism 12 within the reaction time.

[0069] This embodiment realizes a precise test of the mechanical operation test of the first micro switch 13 to be tested.

[0070] In an exemplary embodiment, the measurement and control host is further configured to determine that the mechanical operation test of the first microswitch 13 to be tested is qualified when the first opening and closing detection signals of the first microswitch 13 to be tested for a preset number of times all meet a first preset condition.

[0071] Exemplarily, the first microswitch 13 to be tested performs 5 consecutive closing-opening operation cycles at a preset rated power supply voltage, and the first opening and closing detection signals all indicate correctness; and the first microswitch 13 to be tested performs 5 consecutive closing-opening operation cycles at a preset minimum power supply voltage, and the first opening and closing detection signals all indicate correctness; and the first microswitch 13 to be tested performs 5 consecutive closing-opening operation cycles at a preset maximum power supply voltage, and the first opening and closing detection signals all indicate correctness, then it is determined that the mechanical operation test of the first microswitch 13 to be tested is qualified.

[0072] In an exemplary embodiment, referring to Figure 1 The first test station 1 includes two first calibration tables 11, a first type of first transmission mechanism 121 and a second type of first transmission mechanism 122, wherein the first type of first transmission mechanism 121 is used to touch the action reed of the push-type first microswitch to be tested 131, and the second type of first transmission mechanism 122 is used to touch the action reed of the rotary first microswitch to be tested 132; the second test station 2 includes four second calibration tables 3, and the four second calibration tables 3 are arranged in sequence around the second transmission mechanism 4, wherein at least one second calibration table 3 is used to carry the push-type second microswitch to be tested 211, and at least one second calibration table 3 is used to carry the rotary second microswitch to be tested 212, and the second transmission mechanism 4 is used to touch the action reed of each second microswitch to be tested 21 respectively.

[0073] In this embodiment, by setting the number of calibration stations, the micro switch calibration system is made more portable and flexible, which is conducive to testing micro switches in various practical application scenarios.
