[0043] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0044] In this application, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.
[0045] In addition, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may or may not be the same in type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.
[0046] The technical solution of the present application will be further described below with reference to specific embodiments and drawings.
[0047] Please also refer to Figure 1 、 Figure 2 and Figure 3 The embodiment of the present application discloses a test system 1, comprising a frame 11, a first integrated component 12, a transfer device 131 and a second integrated component 14. The frame 11 is provided with a test station. The first integrated component 12 is slidably arranged on the frame 11 along a first direction, and is used to integrate a plurality of detection ports. The first integrated component 12 has a first docking end 121. The transfer device 131 is used to carry the fuel cell engine 2. The transfer device 131 can move to the test station. The fuel cell engine 2 has a plurality of pipe ports corresponding to the plurality of detection ports. The second integrated component 14 is arranged on the transfer device 131 and is used to integrate a plurality of pipe ports of the fuel cell engine 2. The second integrated component 14 has a second docking end 141 that can dock with the first docking end 121. The test station is configured so that when the transfer device 131 moves to the test station, the first docking end 121 and the second docking end 141 are opposite to each other along the first direction.
[0048] In this embodiment, the first assembly 12 and the second assembly 14 can both be plate-like structures. The plate-like structure can reduce the weight of the first assembly 12 and the second assembly 14, and at the same time can expand the relative area when the first assembly 12 and the second assembly 14 are docked. Therefore, on the basis of integrating multiple detection ports of the fuel cell engine 2 on the second assembly 14, it is ensured that the ports will not interfere with each other.
[0049] The working principle of this embodiment is that when the transfer device 131 is at the workstation of the previous process (such as the fuel cell engine 2 assembly workstation, etc.), the multiple pipe openings of the fuel cell engine 2 are integrated into the second assembly 14 through pipes, and then the transfer device 131 is moved to the test workstation of the test system 1 to perform the test process. During the test process, the first docking end 121 of the first assembly 12 and the second docking end 141 of the second assembly 14 are first made opposite to each other along the first direction, and then the first assembly 12 is driven to move along the first direction toward the second assembly 14, so that the first docking end 121 and the second docking end 141 are docked, and the test is performed after the docking is completed.
[0050] It can be understood that when the first docking end 121 of the first assembly 12 is docked with the second docking end 141 of the second assembly 14, the multiple detection ports integrated in the first assembly 12 are docked with the corresponding pipe ports integrated in the second assembly 14 at the same time. Compared with manually docking the pipe ports of the fuel cell engine 2 with the corresponding detection ports one by one during the testing process, docking time can be saved, docking efficiency can be improved, and thus testing efficiency can be improved.
[0051] Please continue reading Figure 1 、 Figure 2 and Figure 3In some embodiments, the testing system 1 further includes a driving unit 132 , which is connected to the first integrated component 12 to drive the first integrated component 12 to reciprocate along the first direction.
[0052] For example, the driving unit 132 may be a cylinder.
[0053] In this embodiment, after the first docking end 121 and the second docking end 141 of the first integrated component 12 are opposite to each other along the first direction, the driving unit 132 drives the first integrated component 12 to approach the second integrated component 14 along the first direction, and finally docks the first docking end 121 with the second docking end 141, and a test is performed after the docking is completed.
[0054] After the test is completed, the drive unit 132 drives the first assembly 12 to move in the opposite direction in the first direction and reset. If the test passes, the transfer device 131 can transfer the fuel cell engine 2 to a subsequent process for further processing. If the test fails, the transfer device 131 can transfer the fuel cell engine 2 to a previous process for reprocessing.
[0055] By driving the first integrated component 12 through the driving unit 132 , the movement accuracy of the first integrated component 12 can be improved.
[0056] In some other embodiments, the first integrated component 12 may also be driven manually to reciprocate along the first direction.
[0057] In some specific embodiments, the testing system 1 further includes a position detection unit and a control unit. The position detection unit is configured to detect whether the transfer device 131 has moved to the testing station. If so, the position detection unit generates a first detection signal. The control unit is electrically connected to the position detection unit and the drive unit 132 . Upon receiving the first detection signal, the control unit controls the drive unit 132 to move the first assembly 12 toward the second assembly 14 .
[0058] Among them, detecting whether the transfer device 131 moves to the test station means detecting whether the transfer device 131 moves to the test station of the frame 11 and whether the first docking end 121 of the first integrated component 12 and the second docking end 141 of the second detection component are opposite to each other along the first direction.
[0059] In this embodiment, when the position detection unit detects that the transfer device 131 moves to the test station, the position detection unit generates a first detection signal and sends it to the control unit. After receiving the first detection signal, the control unit generates a drive signal and sends it to the drive unit 132. After receiving the drive signal, the drive unit 132 drives the first integrated component 12 to move toward the second integrated component 14 along the first direction, so that the first docking end 121 of the first integrated component 12 docks with the second docking end 141 of the second integrated component 14.
[0060] It is understandable that in this embodiment, when the position detection unit does not detect that the transfer device 131 has moved to the test station, the position detection unit may be in a silent state. In other words, when the position detection unit does not detect that the transfer device 131 has moved to the test station, the position detection unit will not send the first detection signal to the control unit. Of course, in other embodiments, when the position detection unit detects that the transfer device 131 has moved to the test station, the position detection unit may also generate a second detection signal and send it to the control unit, and the control unit will not generate a drive signal after receiving the second detection signal.
[0061] In some other more specific embodiments, after the position detection unit generates the first detection signal, the driving unit 132 can be manually controlled to drive the first integrated component 12 to move toward the second integrated component 14 along the first direction.
[0062] In some embodiments, the position detection unit is a proximity switch.
[0063] A proximity switch is a position switch that operates without direct mechanical contact with moving parts. In other words, when an object approaches the proximity switch's sensing distance, the switch activates without mechanical contact or pressure. Proximity switches combine the characteristics of both travel switches and micro switches with sensing capabilities, offering reliable operation, stable performance, fast frequency response, long service life, and strong anti-interference capabilities.
[0064] In this embodiment, when the proximity switch senses that the transfer device 131 moves to the testing station, the proximity switch generates a first detection signal and sends it to the control unit.
[0065] When the transfer device 131 moves to the test station, the proximity switch will not contact the transfer device 131, thereby not changing the position of the transfer device 131, ensuring the accuracy of the position of the transfer device 131 when it moves to the test station.
[0066] In some other embodiments, the position detection unit may also be a mechanical limit switch, etc.
[0067] In some more specific embodiments, the testing system 1 further includes a pressure detection unit, which is electrically connected to the control unit and is used to detect the pressure when the first integrated component 12 and the second integrated component 14 are docked.
[0068] When the first butt joint end 121 of the first assembly 12 is butt jointed with the second assembly 14, the butt joint may appear to be successful, but there may actually be a gap between the first butt joint end 121 and the second butt joint end 141. To address this issue, a pressure detection unit may be provided in this embodiment to detect the pressure when the first assembly 12 and the second assembly 14 are butt jointed.
[0069] Specifically, when the pressure detection unit detects that the pressure when the first docking end 121 of the first integrated component 12 and the second docking end 141 of the second integrated component 14 are docked does not reach the preset pressure, the driving unit 132 gradually increases the force applied to the first integrated component 12 toward the second integrated component 14 to reduce the gap between the first docking end 121 and the second docking end 141; when the pressure detection unit detects that the pressure when the first docking end 121 of the first integrated component 12 and the second docking end 141 of the second integrated component 14 are docked reaches the preset pressure, the pressure detection unit generates a third detection signal and sends it to the control unit. After receiving the third detection signal, the control unit controls the driving unit 132 to stop increasing the force applied to the first integrated component 12 toward the second integrated component 14, so that the force applied by the driving unit 132 to the first integrated component 12 remains at its current size.
[0070] In this embodiment, the pressure detection unit can be used to determine whether the first docking end 121 and the second docking end 141 are successfully docked, so that the situation where the first docking end 121 and the second docking end 141 are unsuccessful in docking can be discovered in time.
[0071] In some other more specific embodiments, a distance detection unit may also be provided to detect the distance between the first docking end 121 and the second docking end 141 .
[0072] In some specific embodiments, the test system 1 further includes an airtightness detection unit electrically connected to the control unit. The control unit is configured to control the airtightness detection unit to detect the airtightness of the test system 1 when the pressure detected by the pressure detection unit when the first assembly 12 and the second assembly 14 are connected reaches a preset pressure.
[0073] The airtightness of the test system 1 refers to the airtightness between the fuel cell engine 2 and the activation test unit described below.
[0074] In this embodiment, when the pressure detection unit detects that the pressure when the first docking end 121 of the first integrated component 12 and the second docking end 141 of the second integrated component 14 are docked reaches a preset pressure and the control unit receives a third detection signal, the control unit controls the air tightness detection unit to detect the air tightness of the test system 1 to verify whether the first docking end 121 and the second docking end 141 are successfully docked, thereby avoiding the situation where the pressure detection unit detects that the docking of the first docking end 121 and the second docking end 141 is successful but is actually unsuccessful.
[0075] In some other more specific embodiments, the airtightness detection unit may also be controlled manually.
[0076] In some specific embodiments, the test system 1 further includes an activation test unit connected to the plurality of detection ports and electrically connected to the control unit. The control unit is configured to control the activation test unit to perform an activation test on the fuel cell engine 2 when the airtightness detection unit detects that the airtightness of the test system 1 meets the requirements.
[0077] In this embodiment, when the air tightness detection unit detects that the air tightness of the test system 1 meets the standard, the air tightness detection unit generates a fourth detection signal and sends it to the control unit. After receiving the fourth detection signal, the control unit controls the activation test unit to perform an activation test on the fuel cell engine 2.
[0078] In some other more specific embodiments, the activation test unit may also be controlled manually.
[0079] Please refer again Figure 1 and Figure 2 In some embodiments, the test system 1 further includes a first fixing member 151 , and the first fixing member 151 is configured to fix the transfer device 131 to the test station when the transfer device 131 moves to the test station.
[0080] In this embodiment, when the transfer device 131 moves to the test station, the first fixing member 151 fixes the transfer device 131 to the test station to limit the relative position between the transfer device 131 and the frame 11, thereby preventing the transfer device 131 from shifting after moving to the test station due to other reasons, thereby causing the relative position between the first integrated component 12 and the second integrated component 14 to shift, thereby causing the first integrated component 12 and the second integrated component 14 to fail to dock successfully.
[0081] In some other embodiments, a first accommodating cavity matching the transfer device 131 may also be set at the test station of the rack 11, and the outer surface of the transfer device 131 and the inner wall of the first accommodating cavity formed by the rack 11 may be fitted together, thereby fixing the transfer device 131 to the test station.
[0082] In some embodiments, the first fixing member 151 is a positioning pin, which is disposed on the frame 11 and is connected to the transfer device 131 when the transfer device 131 moves to the testing station.
[0083] When the transfer device 131 moves to the testing station, the positioning pins connect and position the transfer device 131 to correct and fix the relative position of the transfer device 131 and the rack 11 .
[0084] In some other embodiments, the first fixing member 151 may also be a component with a connecting function, such as a bolt.
[0085] See also Figure 4 In some more specific embodiments, the test system 1 further includes a second fixing member 152 , which is configured to connect the first integrated component 12 and the second integrated component 14 when the first docking end 121 and the second docking end 141 are docked.
[0086] It is understandable that after the first butt joint end 121 of the first assembly 12 and the second butt joint end 141 of the second assembly 14 are butt jointed, the first butt joint end 121 and the second butt joint end 141 may become misaligned due to human factors or other factors. To address this issue, in this embodiment, the first assembly 12 and the second assembly 14 can be connected by a second fixing member 152 to limit the relative position of the first assembly 12 and the second assembly 14 after the butt joint.
[0087] In some other more specific embodiments, a second accommodating cavity can be set at the test station of the rack 11, and the first integrated component 12 and the second integrated component 14 are both located in the second accommodating cavity after docking, and the relative position between the first integrated component 12 and the second integrated component 14 is limited by the second accommodating cavity.
[0088] See also Figure 5 In some embodiments, the testing system 1 further includes a sealing member 16 , which is disposed at the first docking end 121 and / or the second docking end 141 .
[0089] In this embodiment, after the first butt joint end 121 and the second butt joint end 141 are butt jointed, the sealing member 16 seals the gap between the first butt joint end 121 and the second butt joint end 141 , thereby improving the airtightness of the testing system 1 .
[0090] It can be understood that there are three implementations of the sealing member 16 being disposed at the first docking end 121 and / or the second docking end 141 , which will be described in detail below.
[0091] In the first embodiment, the first docking end 121 is provided with a first seal 16, and the first seal 16 has a first assembly portion protruding from the first docking end 121. After the first docking end 121 is docked with the second docking end 141, the first assembly portion is attached to the outer surface of the second docking end 141 so that the first seal 16 seals the gap between the first docking end 121 and the second docking end 141.
[0092] In the second embodiment, the second docking end 141 is provided with a second sealing member 16, and the second sealing member 16 has a second assembly portion protruding from the second docking end 141. After the first docking end 121 and the second docking end 141 are docked, the second assembly portion is attached to the outer surface of the first docking end 121 so that the second sealing member 16 seals the gap between the first docking end 121 and the second docking end 141.
[0093] In the third embodiment, the first docking end 121 is provided with a third seal 16, and the second docking end 141 is provided with a fourth seal 16. After the first docking end 121 and the second docking end 141 are docked, the third seal 16 and the fourth seal 16 are fitted together so that the first seal 16 and the second seal 16 cooperate to seal the gap between the first docking end 121 and the second docking end 141.
[0094] In some other embodiments, the first butt joint end 121 and the second butt joint end 141 may be manually tied between the first butt joint end 121 and the second butt joint end 141 after they are butt jointed.
[0095] See also Figure 6 In some embodiments, the first integrated component 12 is provided with a plurality of first transfer channels 122, and the plurality of first transfer channels 122 all include a connected first port 123 and a second port 124, the first port 123 is a detection port, and the second port 124 is located at the first docking end 121; the second integrated component 14 is provided with a plurality of second transfer channels 142, and the plurality of second transfer channels 142 all include a connected third port 143 and a fourth port 144, the plurality of third ports 143 are respectively connected to a plurality of pipeline ports, and the fourth port 144 is located at the second docking end 141.
[0096] In this embodiment, the second assembly 14 is provided with a plurality of second transfer channels 142, each corresponding one-to-one with the plurality of pipe openings of the fuel cell engine 2. When the transfer device 131 is in the previous process position, the plurality of pipe openings of the fuel cell engine 2 are connected to the corresponding third ports 143 of the second transfer channels 142 via pipes. Furthermore, the first assembly 12 is provided with a plurality of first channels corresponding one-to-one with the plurality of second transfer channels 142.
[0097] When the first docking end 121 of the first integrated component 12 is docked with the second docking end 141 of the second integrated component 14, the second port 124 located at the first docking end 121 is docked with the fourth port 144 located at the second docking end 141, thereby connecting the first transfer channel 122 with the corresponding transfer channel, thereby connecting the pipeline port and the detection port of the fuel cell engine 2.
[0098] In some other embodiments, the second integrated component 14 may be provided with multiple second through holes, one end of the multiple pipes is connected to the corresponding pipe openings of the fuel cell engine 2, and the other end extends into the corresponding first through holes and is flush with the second docking surface.
[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them.
