TECHNICAL FIELD

[0001] The present application relates to the technical field of switch testing, in particular to a stop assembly, a conveying mechanism and a switch testing device. BACKGROUND

[0002] Switches are commonly used network devices for optical-electric signal forwarding. During the research and development and production of switches, environmental testing is required. Environmental testing simulates the working of switches in various environments, such as high-temperature or low-temperature environments, to verify the reliability of the working performance of switches and analyze the influence degree and mechanism of environmental factors.

[0003] Currently, common testing experiments are sample detection by third-party laboratories. As the production of switches gradually increases, even if the sampling proportion is expanded, it is impossible to ensure that every switch is a qualified product. Therefore, in related technologies, there are also designs of testing devices for batch testing of switches, which automatically convey switches in batches to the testing devices. The position of the switch may be offset during testing in the device, thereby affecting the testing structure. CONTENT OF THE UTILITY MODEL

In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0029] The present application relates to a switch test device, the switch test device comprising a conveying mechanism, the switch moving on the conveying mechanism to a position in the switch test device to be tested, and then performing high and low temperature test of the switch.

[0030] Further, the conveying mechanism is provided as at least one to enable at least one switch to be synchronously fed into the switch test device, thereby improving efficiency.

[0031] The application relates to a conveying mechanism, which comprises a conveying assembly and a stop assembly 1000, the conveying assembly having a conveying channel, and a stop component 1100 of the stop assembly 1000 being located in the conveying channel.

[0032] Specifically, the conveying channel extends along a first direction which is parallel to the conveying direction of the switches in the conveying mechanism. The switches are moved in the conveying assembly along the first direction to a position to be tested in the switch testing device, and the stop component 1100 can prevent the movement of the switches to prevent the movement of the switches at the position to be tested.

[0033] It can be understood that the conveying mechanism can be applied not only to the switch testing device but also to new energy automobile controller testing devices, new energy photovoltaic testing devices, 3C notebook testing devices and the like, and in this case, the conveyed materials on the conveying mechanism are other types of products to be tested.

[0034] It should be noted that in the conveying channel, the forward direction is that the switches enter the position to be tested in the switch testing device along the first direction. In the switch testing device, when the switches move to the position to be tested, at least one of the front side and the rear side of the switches is stopped by the stop component 1100.

[0035] In some embodiments, the switches can be reciprocally conveyed in the conveying assembly along the first direction. Specifically, the switches are conveyed forward in the conveying assembly to the position to be tested in the switch testing device, and the stop component 1100 is used to prevent the backward movement of the switches during the testing, and the switches are conveyed backward after the testing is completed.

[0036] In this case, the stop component 1100 provided in the conveying channel is used to prevent the backward movement of the switches during the testing, and plays a role of check valve anti-reverse. Specifically, at the position to be tested, the rear side of the switches is provided with the stop assembly 1000, and the stop component 1100 of the stop assembly 1000 stops the rear side of the switches, so that the switches cannot move backward.

[0037] It can be understood that the stop component 1100 can avoid the switches when the switches are conveyed forward to the position to be tested in the switch testing device. After the switches enter the position to be tested in the switch testing device, the stop component 1100 can prevent the backward movement of the switches. When the switches complete the testing and are conveyed backward, the stop component 1100 can avoid the switches.

[0038] In other alternative embodiments, the switches can be conveyed forward in the conveying assembly along the first direction. Specifically, the switches are conveyed forward in the conveying assembly to the position to be tested in the switch testing device, and the switches continue to be conveyed forward after the testing is completed.

[0039] In this case, during testing, the stop component 1100 is arranged in the conveying channel to prevent the switch from moving forward and backward. Specifically, at the position to be tested, the front side and the rear side of the switch are provided with the stop assembly 1000, and the stop components 1100 of the stop assemblies 1000 on the front side and the rear side simultaneously abut against the side of the switch, thereby preventing the switch from moving. Alternatively, during testing, the stop component 1100 is arranged in the conveying channel to prevent the switch from moving forward. Specifically, at the position to be tested, the front side of the switch is provided with the stop assembly 1000, and the stop component 1100 of the stop assembly 1000 abuts against the front side of the switch, thereby preventing the switch from moving forward.

[0040] In some embodiments, the conveying assembly includes two conveying components 2100 extending along a first direction, and the two conveying components 2100 are arranged at intervals along a second direction perpendicular to the first direction in a horizontal plane. It can be understood that the two conveying components 2100 constitute the conveying channel of the conveying assembly, and the stop component 1100 is located between the two conveying components 2100.

[0041] Further, the conveying component 2100 includes a plurality of rollers arranged in at least one column along the first direction. Alternatively, the conveying component 2100 is designed to include a plurality of balls or rollers.

[0042] In some examples, the conveying component 2100 is designed as a non-powered structure, and the switch moves on the conveying component 2100 by external force.

[0043] In other examples, the conveying component 2100 is designed as a powered structure to enable the conveying assembly to automatically convey the switch, and a power source is provided to power the rollers or rollers.

[0044] It can be understood that, as the powered conveying component 2100, at least the conveying component 2100 can be alternatively designed to convey the switch by means of a transmission belt or a chain plate.

[0045] Other configurations and operations of the switch testing device and the conveying mechanism are known to those skilled in the art in the related art, and will not be described in detail here. The structure of the stop assembly 1000 will be described below.

[0046] The present application relates to a stop assembly 1000, which includes a stop component 1100 and a stop base 1200, the stop component 1100 is hinged to the stop base 1200, and the stop component 1100 has a stop end 1101. The stop end 1101 is raised, and the stop end 1101 can prevent the switch from moving backward. The stop end 1101 has a stop surface 1102 for abutting against the switch to achieve the stop of the switch.

[0047] Further, the stop component 1100 has an unlocking end 1103, which can lower the stop end 1101 when subjected to a force, thereby avoiding the switchboard. Specifically, the stop end 1101 and the unlocking end 1103 are spaced apart along the first direction, in which case, by virtue of the hinge between the stop component 1100 and the stop base 1200, the stop end 1101 and the unlocking end 1103 form two ends of a lever. It can be understood that when one of the stop end 1101 and the unlocking end 1103 is raised, the other is lowered.

[0048] It should be noted that the stop assembly 1000 includes an unlocking assembly, which acts on the unlocking end 1103 of the stop component 1100, thereby lifting the unlocking end 1103. Specifically, the unlocking assembly includes a movable unlocking movable piece 1301, which can move along a set trajectory, and is used to lift the unlocking end 1103.

[0049] It can be understood that when the switchboard needs to leave the position to be tested to complete the test, the switchboard will pass through the position of the stop component 1100 again, at which time the stop component 1100 needs to avoid the switchboard. The unlocking movable piece 1301 lifts the unlocking end 1103 to lower the stop end 1101, thereby avoiding the switchboard.

[0050] In some embodiments, the unlocking assembly includes an unlocking drive assembly, which is connected to the unlocking movable piece 1301 and provides power for the movement of the unlocking movable piece 1301.

[0051] Specifically, under the drive of the unlocking drive assembly, the unlocking movable piece 1301 moves along a straight line, and the unlocking movable piece 1301 can reciprocate along the first direction, thereby approaching or moving away from the unlocking end 1103. It can be understood that when the unlocking movable piece 1301 approaches the unlocking end 1103 along the first direction and abuts against the unlocking end 1103, as the unlocking movable piece 1301 continues to move along the first direction, the unlocking movable piece 1301 can lift the unlocking end 1103. Correspondingly, when the unlocking movable piece 1301 moves away from the unlocking end 1103 along the first direction, the unlocking movable piece 1301 gradually separates from the unlocking end 1103, thereby releasing the lifting of the unlocking end 1103.

[0052] In some examples, the unlocking driving assembly drives the unlocking movable component 1301 to reciprocate along the first direction in a screw pair manner. Specifically, the unlocking driving assembly comprises an unlocking driving motor 1302, an unlocking driving rod 1303, an unlocking moving base 1304 and an unlocking driving base 1305, the unlocking driving rod 1303 extends along the first direction, the unlocking driving rod 1303 is connected with a rotating shaft of the unlocking driving motor 1302, the unlocking driving motor 1302 is arranged on the unlocking driving base 1305, and the unlocking moving base 1304 is movably arranged on the unlocking driving base 1305. The unlocking moving base 1304 is provided with a threaded hole, the unlocking driving rod 1303 is provided with an external thread, the unlocking driving rod 1303 is in screw transmission with the unlocking moving base 1304, and the unlocking movable component 1301 is connected with the unlocking moving base 1304.

[0053] It can be understood that the unlocking driving motor 1302 drives the unlocking driving rod 1303 to rotate, the unlocking driving rod 1303 drives the unlocking moving base 1304 to move along the first direction, and the unlocking moving base 1304 drives the unlocking movable component 1301 to move along the first direction.

[0054] Regarding the manner in which the unlocking driving assembly drives the unlocking moving base 1304, at least the following alternative manners exist: the unlocking driving assembly drives the unlocking moving base 1304 in a belt transmission manner; or, the unlocking driving assembly drives the unlocking moving base 1304 in a gear and rack transmission manner; or, the unlocking driving assembly drives the unlocking moving base 1304 by means of a pneumatic cylinder or a hydraulic cylinder; or, the unlocking driving assembly drives the unlocking moving base 1304 by means of a telescopic push rod of a motor.

[0055] In order to improve the stability of the movement of the unlocking movable component 1301, the unlocking driving assembly is further designed to comprise an unlocking guide structure, the unlocking guide structure is arranged on the unlocking driving base 1305, the unlocking moving base 1304 is movably connected with the unlocking guide structure, and the unlocking guide structure extends along the first direction. Under the guidance of the unlocking guide structure, the unlocking moving base 1304 reciprocates along the first direction.

[0056] In some examples, the unlocking guide structure is arranged as a guide rail, and the unlocking moving base 1304 reciprocates along the guide rail by means of a sliding block. At least the following alternative manners exist for the unlocking guide structure: the unlocking guide structure is arranged as a guide rod; or, the unlocking guide structure is arranged as a sliding groove on the unlocking moving base 1304.

[0057] In some embodiments, the unlocking driving assembly comprises a stroke monitoring assembly for monitoring the moving stroke of the unlocking movable element 1301. When the unlocking movable element 1301 approaches the unlocking end 1103 and lifts up the unlocking end 1103, the stroke monitoring assembly generates a first signal indicating that the unlocking movable element 1301 has moved to a position sufficient to allow the locking end 1101 to avoid the switch. When the unlocking movable element 1301 moves away from the unlocking end 1103 and releases the lifting of the unlocking end 1103, the stroke monitoring assembly generates a second signal indicating that the unlocking movable element 1301 has moved to a position sufficient to allow the unlocking end 1103 to drop and the locking end 1101 to be lifted to a position to prevent the movement of the switch.

[0058] Specifically, the stroke monitoring assembly comprises a first sensor, a second sensor and a signal triggering structure, the first sensor and the second sensor are arranged at intervals, the interval of the first sensor and the second sensor is the stroke range of the unlocking movable element 1301, and the signal triggering structure is used to trigger the signal of the first sensor or the second sensor.

[0059] In some examples, the signal triggering structure is arranged on the unlocking moving seat 1304, and the first sensor and the second sensor are arranged on the unlocking driving base 1305. Further, the first sensor and the second sensor are arranged at intervals along a first direction.

[0060] In other examples, the signal triggering structure is arranged on the unlocking driving base 1305, and the first sensor and the second sensor are arranged on the unlocking moving seat 1304.

[0061] It should be noted that the first sensor and the second sensor are arranged as infrared sensors or photoelectric sensors, and the signal triggering structure is arranged as a baffle or a shield.

[0062] Regarding the movement trajectory of the unlocking movable element 1301, at least the following alternative embodiments exist.

[0063] In some alternative embodiments, under the driving of the unlocking driving assembly, the unlocking movable element 1301 moves along a circular trajectory. The circular trajectory of the movement of the unlocking movable element 1301 surrounds a set center, and the unlocking driving assembly drives the unlocking movable element 1301 to move circularly through a rotating shaft or a connecting rod mechanism.

[0064] It can be understood that in this case, the arrangement of the unlocking guide structure and the stroke monitoring assembly are both adjusted adaptively along the circular trajectory.

[0065] In other alternative embodiments, the unlocking movable element 1301 can move reciprocally along a straight trajectory in a third direction parallel to the vertical direction, i.e., the unlocking movable element 1301 moves up and down.

[0066] In some embodiments, one of the unlocking end 1103 and the unlocking movable piece 1301 is provided with an inclined pressure surface 1401, which is provided as a flat surface or a curved surface, and the unlocking end 1103 is gradually lifted by the pressure surface 1401 between the unlocking end 1103 and the unlocking movable piece 1301 during movement.

[0067] Specifically, the side surface of the unlocking end 1103 for abutting against the unlocking movable piece 1301 is provided with the inclined pressure surface 1401, which forms the unlocking end 1103 with gradually changing thickness on the stop component 1100. When the unlocking movable piece 1301 approaches the unlocking end 1103, the unlocking movable piece 1301 first abuts against the position of the pressure surface 1401 with small thickness on the unlocking end 1103, and gradually abuts against the pressure surface 1401 with large thickness on the unlocking end 1103 with the gradual movement of the unlocking movable piece 1301, and then gradually lifts the unlocking end 1103.

[0068] Of course, the unlocking movable piece 1301 can also be provided with the inclined pressure surface 1401 for abutting against the unlocking end 1103.

[0069] It should be noted that one of the unlocking end 1103 and the unlocking movable piece 1301 is provided with the inclined pressure surface 1401, and the other one is provided with an arc surface structure 1402 for contacting the pressure surface 1401 and lifting the unlocking end 1103. The arc surface structure 1402 can reduce the friction between the unlocking movable piece 1301 and the unlocking end 1103, so as to make the movement of the unlocking movable piece 1301 more smooth.

[0070] It can be understood that if the pressure surface 1401 is provided on the unlocking end 1103, the arc surface structure 1402 is provided on the unlocking movable piece 1301. If the pressure surface 1401 is provided on the unlocking movable piece 1301, the arc surface structure 1402 is provided on the unlocking end 1103.

[0071] In some examples, the arc surface structure 1402 can roll to achieve a rolling friction contact mode. Specifically, the arc surface structure 1402 is provided as a rolling wheel. Of course, the arc surface structure 1402 that can achieve rolling contact can also be designed as a ball or a roller.

[0072] In other examples, the arc surface structure 1402 is designed as a sliding friction contact mode. Specifically, the arc surface structure 1402 is provided as an arc-shaped end surface. Further, the arc surface structure 1402 is provided as a spherical surface.

[0073] In some embodiments, the stop assembly 1000 comprises a stop reset member for lifting the stop end 1101, the stop reset member is arranged on the stop base 1200, the stop reset member exerts a force on the stop component 1100 and lifts the stop end 1101, so that the stop end 1101 prevents the switch from moving. Specifically, the stop reset member comprises a stop elastic member 1500, the stop elastic member 1500 exerts an elastic force on the stop component 1100 and lifts the stop end 1101.

[0074] Further, the stop elastic member 1500 generates elastic potential energy under compression and exerts an elastic pushing force on the stop component 1100. Specifically, the stop elastic member 1500 is arranged as a compression spring, the stop elastic member 1500 is located between the stop base 1200 and the stop component 1100, one end of the stop elastic member 1500 abuts against the stop base 1200, and the other end of the stop elastic member 1500 abuts against the stop component 1100.

[0075] In some examples, the stop base 1200 is provided with a first mounting structure, and one end of the stop elastic member 1500 is arranged at the first mounting structure. Specifically, the first mounting structure is arranged as a groove, and the end of the stop elastic member 1500 is inserted into the groove. Alternatively, the first mounting structure is arranged as a stand, and the end of the stop elastic member 1500 is sleeved on the stand.

[0076] In some examples, the stop component 1100 is provided with a second mounting structure, and the other end of the stop elastic member 1500 is arranged at the second mounting structure. Specifically, the second mounting structure is arranged as a groove, and the end of the stop elastic member 1500 is inserted into the groove. Alternatively, the second mounting structure is arranged as a stand, and the end of the stop elastic member 1500 is sleeved on the stand.

[0077] Regarding the structure of the stop reset member or the stop elastic member 1500, at least the following alternative embodiments also exist.

[0078] In some alternative embodiments, the stop elastic member 1500 generates elastic potential energy under tension and exerts an elastic pulling force on the stop component 1100. Specifically, the stop elastic member 1500 is arranged as a tension spring.

[0079] In other alternative embodiments, the stop reset member is arranged as a torsion spring, which is sleeved on the stop base 1200 for mounting the hinge shaft of the stop component 1100.

[0080] In still other alternative embodiments, the stop elastic member 1500 is arranged as a pneumatic spring, which generates an elastic pushing force under compression.

[0081] It should be noted that under the action of the stop elastic member 1500, the stop member 1100 is normally kept in the state that the stop end 1101 is upturned. When the switchboard is conveyed to the position to be tested, the switchboard first passes the unlocking end 1103 and then the stop end 1101 during the movement in the first direction, and the stop end 1101 is automatically pressed down by the switchboard, so that the stop end 1101 avoids the switchboard.

[0082] There are at least the following alternative embodiments about the way that the stop end 1101 of the stop member 1100 is reset to the upturned state.

[0083] In some alternative embodiments, the moment generated by the unlocking end 1103 is greater than the moment generated by the stop end 1101, with the hinged position of the stop member 1100 and the stop base 1200 as the fulcrum. In this case, according to the principle of leverage, the stop end 1101 can be automatically upturned.

[0084] Specifically, the distance from the unlocking end 1103 to the hinged shaft of the stop member 1100 is greater than the distance from the stop end 1101 to the hinged shaft along the length direction of the stop member 1100. Alternatively, the weight of the unlocking end 1103 is greater than the weight of the stop end 1101.

[0085] In some embodiments, the stop end 1101 is provided with a rolling contact 1104 for contacting the switchboard to reduce the resistance when the switchboard passes the stop end 1101.

[0086] Specifically, the rolling contact 1104 is provided as at least one, and the rolling contact 1104 is provided as a roller. It can be understood that the rolling contact 1104 can be alternatively designed as a ball or a roller.

[0087] There are at least the following alternative embodiments about the contact between the stop end 1101 and the bottom of the switchboard.

[0088] In some alternative embodiments, the side surface of the stop end 1101 for contacting the switchboard is provided with an inclined guide surface, and the guide surface is inclined relative to the axis of the length direction of the stop member 1100. When the stop end 1101 is in the upturned state, the bottom of the switchboard gradually presses down the stop end 1101 along the inclined guide surface when the switchboard passes the stop end 1101, so that the stop end 1101 avoids the switchboard.

[0089] Further, the guide surface is provided as a plane or a curved surface.
