[0043] 1 to 3 , a pipeline detection switching device 100 provided in one embodiment of the present application includes a bracket 1, an air source module 2, a switching module 3 and a moving module 4. Among them:

[0044] The bracket 1 includes a top plate 11, and the top plate 11 is provided with a first connecting hole 111 and a second connecting hole 112 passing through at intervals. The air source module 2 includes a first air source block 21 and a second air source block 22. The first air source block 21 and the second air source block 22 are both arranged on one side of the top plate 11. The first air source block 21 is provided with a first air inlet 211 and a first air outlet that are connected. The first air inlet 211 is used to communicate with the first detection device, and the first air outlet is connected to the first connecting hole 111. The second air source block 22 is provided with a second air inlet 221 and a second air outlet that are connected. The second air inlet 221 is used to communicate with the second detection device, and the second air outlet is connected to the second connecting hole 112. The switching module 3 is arranged on the other side of the top plate 11, and is provided with a first air guide hole 32, a second air guide hole 33 and an air receiving hole 31 that are connected to each other. The opening of the first air guide hole 32 and the opening of the second air guide hole 33 are both arranged opposite to the top plate 11, and the air receiving hole 31 is used to communicate with the workpiece to be measured. The switching module 3 has a first detection position and a second detection position. In the first detection position, the first air guide hole 32 is connected to the first communication hole 111, and the top plate 11 blocks the second air guide hole 33. In the second detection position, the second air guide hole 33 is connected to the second communication hole 112, and the top plate 11 blocks the first air guide hole 32. The moving module 4 is drivingly connected to the switching module 3, and the moving module 4 is used to drive the switching module 3 to move between the first detection position and the second detection position.

[0045] In the above-mentioned pipeline switching device, since the first air inlet 211 is connected to the first detection device, the second air inlet 221 is connected to the second detection device, the first air outlet is connected to the first connecting hole 111, and the second air outlet is connected to the second connecting hole 112, the workpiece to be tested is connected to the air receiving hole 31 of the switching module 3, and when the switching module 3 is in the first detection position, the first air guide hole 32 of the switching module 3 is connected to the first connecting hole 111, and the second air guide hole 33 is blocked; when the switching module 3 is in the second detection position, the second air guide hole 33 of the switching module 3 is connected to the second connecting hole 112, and the first air guide hole 32 is blocked, so when the switching module 3 is in the second detection position, the second air guide hole 33 of the switching module 3 is connected to the second connecting hole 112, and the first air guide hole 32 is blocked. When the switching module 3 is in the first detection position, the first detection device can be connected to the workpiece to be tested through the first air inlet 211, the first air outlet, the first connecting hole 111, the first air guide hole 32 and the air receiving hole 31 to form a first detection circuit, so that the first detection device can perform a first type of detection on the workpiece to be tested; when the switching module 3 is in the second detection position, the second detection device can be connected to the workpiece to be tested through the second air inlet 221, the second air outlet, the second connecting hole 112, the second air guide hole 33 and the air receiving hole 31 to form a second detection circuit, so that the second detection device can perform a second type of detection on the workpiece to be tested. Therefore, the switching module 3 can be used as an intermediate bridge, so that the workpiece to be tested can be connected to the first detection device and the second detection device respectively, so that the workpiece to be tested can be switched between the first type of detection and the second type of detection, thereby realizing multiple types of detection of the workpiece to be tested. Among them, since the moving module 4 can drive the switching module 3 to move between the first detection position and the second detection position, the switching module 3 can reliably switch between the first type of detection and the second type of detection under the drive of the moving module 4. Therefore, through the pipeline inspection switching device 100, the workpiece to be inspected can complete various types of inspections at the same station, thereby avoiding the workpiece disassembly and assembly operations added by switching stations, and effectively improving the inspection efficiency. In addition, it can also avoid the need to transport the workpiece to be inspected between different stations, reduce the inspection cost, and avoid workpiece defects caused by improper transportation.

[0046] Among them, the detection instruments in the first detection device and the second detection device connected to the pipeline detection switching device 100 can be adjusted according to the actual needs of the product, so that the pipeline detection switching device 100 can adjust the switching detection type according to the needs of the product. For example, for air-conditioning pipelines, the pipeline detection switching device 100 can switch between flow detection and sealing detection; or, for products for sealing detection, the pipeline detection switching device 100 can switch between low-pressure detection sealing detection and high-pressure detection sealing detection; or, for products for flow detection, the pipeline detection switching device 100 can switch between small flow detection and large flow detection. In this way, it is beneficial to enhance the flexibility and compatibility of the application of the pipeline detection switching device 100. In addition, the pipeline detection switching device 100 can be directly connected to the automation equipment for automatic testing, or it can be directly connected to the instrument for use alone with manual assistance.

[0047] Schematically, the first detection device may include a leak detector with an air source. In this way, when the switching module 3 is in the first detection position, the air tightness of the workpiece can be detected by the first detection device. Specifically, when the switching device is in the first detection position, the end of the workpiece to be tested that is away from the air connection hole 31 is blocked, and the leak detector is turned on so that the gas in the air source can enter the switching module 3 through the first air source block 21, and then enter the workpiece to be tested. After the inflation is completed, the air intake is stopped, and the detection end of the first detection device performs a sealing test on the workpiece to be tested (such as detecting whether the pressure in the workpiece changes within a predetermined time period) to determine whether the air tightness of the workpiece to be tested meets the requirements based on the test results. In this way, compared with the traditional water detection method of directly sealing both ends of the pipeline and placing it in water, and detecting the air tightness of the workpiece to be tested by detecting whether bubbles are generated, this air tightness leak detection method can save the time of pipeline drying and help improve detection efficiency.

[0048] Schematically, the second detection device can be a device for flow detection. In this way, when the switching module 3 is in the second detection position, the second detection device can detect the flowability of the workpiece to be tested by detecting the gas flow. The second detection device can, for example, include a gas source, a pressure regulating valve or an electric control valve, a pressure gauge, a valve, and a flow meter 23 for communicating with the second air inlet 221, which are connected in sequence. Specifically, when the switching module 3 is in the second detection position, the end of the workpiece to be tested away from the air receiving hole 31 is kept unblocked, so as to open the valve located on the air inlet side of the flow meter 23, and then the pressure of the second detection circuit is adjusted by the pressure regulating valve or the electric control valve, and the pressure on the pressure gauge is observed. When the pressure is adjusted to the target pressure, the adjustment is stopped, and then the reading on the flow meter 23 is read to determine whether the flowability of the pipeline meets the requirements. In this way, compared with the traditional pressure comparison method of detecting the flowability of the workpiece to be tested by comparing the pressure between the input port and the output port, the result of the gas flow test is not affected by the external air pressure fluctuation, so that the reliability of the test result can be more effectively guaranteed.

[0049] In one embodiment, as shown in FIG. 1 and FIG. 2 , the switching module 3 further has a first in-place position and a second in-place position, the first in-place position is spaced apart from the first detection position, the second in-place position is spaced apart from the second detection position, and in the first in-place position and the second in-place position, the top plate 11 is spaced apart from the switching module 3, the moving module 4 includes a first driving component 41 and a second driving component 42, the first driving component 41 is drivingly connected to the second driving component 42, the second driving component 42 is drivingly connected to the switching module 3, the switching module 3 can be driven by the first driving component 41 to move between the first in-place position and the second in-place position, the second driving component 42 is used to drive the switching module 3 to move between the first in-place position and the first detection position, and is also used to drive the switching module 3 to move between the second in-place position and the second detection position. In this way, the first driving component 41 and the second driving component 42 can cooperate to enable the switching module 3 to move between the first detection position, the first in-place position, the second in-place position and the second detection position in sequence. Among them, since the switching module 3 is spaced apart from the top plate 11 when the switching module is in the first in-position and the second in-position, when the switching module 3 is indirectly moved between the first detection position and the second detection position by using the first in-position and the second in-position, friction between the switching module 3 and the top plate 11 can be avoided during the movement, thereby effectively protecting the switching module 3 and avoiding damage to the switching module 3. At the same time, it can also ensure that the switching module 3 can drive the workpiece to be tested to connect with different detection devices to perform different types of detection items.

[0050] Schematically, in combination with FIG. 1 and FIG. 2, when performing detection, the first drive component 41 can be driven first to move the switching module 3 to the first in-place position, and then the second drive component 42 can be driven to move the switching module 3 closer to the top plate 11 and move from the first in-place position to the first detection position, so that the workpiece to be tested is connected to the first detection device to perform the first type of detection. After completing the first type of detection, the second drive component 42 can be driven to move the switching module 3 away from the top plate 11 to move from the first detection position to the first in-place position, and then the first drive component 41 can be driven to move the switching module 3 from the first in-place position to the second in-place position, and then the second drive component 42 can be driven to move the switching module 3 from the second in-place position to the second detection position, so that the workpiece to be tested is connected to the second detection device, and the second type of detection is performed.

[0051] In other embodiments, the second type of detection may be performed before the first type of detection. For example, the position switching of the switching module 3 during the detection process may be the second in-place position, the second detection position, the second in-place position, the first in-place position and the first detection position in sequence, and the specific movement process will not be repeated.

[0052] Further, in one embodiment, as shown in FIG. 1 and FIG. 2 , the bracket 1 further includes a bottom plate 13 and a support column 12, the bottom plate 13 and the top plate 11 are spaced apart along the first direction S2, and the support column 12 is connected between the bottom plate 13 and the top plate 11 to form a workpiece cavity 1a. The switching module 3 and the moving module 4 are both arranged in the workpiece cavity 1a, the first detection position and the first in-place position are spaced apart and arranged relative to each other in the first direction S2, the second detection position and the second in-place position are spaced apart and arranged relative to each other in the first direction S2, the second detection position and the second in-place position are spaced apart in the first direction S2, the switching module 3 can be driven by the first driving component 41 to move between the first in-place position and the second in-place position along the second direction S1, the second driving component 42 is used to drive the switching module 3 to move between the first in-place position and the first detection position along the first direction S2, and is also used to drive the switching module 3 to move between the second in-place position and the second detection position along the first direction S2, wherein the first direction S2 and the second direction S1 are arranged at an angle. In this way, under the drive of the first driving component 41, the switching module 3 can move to the first in-position relative to the first detection position and the second in-position relative to the second detection position, so that when the second driving component 42 is driven at the first in-position, the switching module 3 can accurately enter the first detection position to perform the first type of detection; when the second driving component 42 is driven at the second in-position, the switching module 3 can accurately enter the second detection position to perform the second type of detection. Therefore, the pipeline detection switching device 100 can achieve the effect of performing multiple types of tests at the same station, thereby improving the detection efficiency.

[0053] Schematically, the first direction S2 is arranged perpendicular to the second direction S1.

[0054] Further, in one embodiment, as shown in FIG. 1 and FIG. 2 , a slide rail 131 extending along the second direction S1 is provided on one side of the bottom plate 13 facing the top plate 11, and the first driving assembly 41 includes a first driving member 411 and a sliding seat 412 that are drivingly connected, the first driving member 411 is provided on the bottom plate, and the second driving assembly 42 is provided on the sliding seat 412, the sliding seat 412 is slidably matched with the slide rail 131, and the sliding seat 412 can drive the switching module 3 to move between the first in-position position and the second in-position position along the second direction S1 under the drive of the first driving member 411. In this way, the stability of the sliding seat 412 when moving along the second direction S1 can be ensured by the sliding cooperation between the sliding seat 412 and the slide rail 131 and the guiding effect of the slide rail 131, so as to ensure that the sliding seat 412 can accurately drive the switching module 3 to move to the first in-position position and the second in-position under the drive of the first driving member 411, thereby ensuring that the switching module 3 can accurately move to the first detection position and the second detection position under the drive of the second driving assembly 42, and the reliability of the pipeline detection switching module 3 is ensured.

[0055] Optionally, the first driving member 411 may be a telescopic cylinder.

[0056] Optionally, in one embodiment, as shown in FIG. 1 and FIG. 2 , the pipeline detection switching device 100 includes a first stopper 51 and a second stopper 52, both of which are arranged in the workpiece cavity 1a and are spaced apart in the second direction S1. In the first position, the sliding seat 412 abuts against the first stopper 51, and in the second position, the sliding seat 412 abuts against the second stopper 52. In this way, when the sliding seat 412 drives the switching module 3 to reciprocate along the second direction S1 under the drive of the first driving member 411, the sliding seat 412 can be accurately limited to the first position relative to the first detection position by abutting against the first stopper 51, so as to ensure that the switching module 3 can reliably move to the first detection position along the first direction S2 for the first type of detection; the sliding seat 412 can also be accurately limited to the second position relative to the second detection position by abutting against the second stopper 52, so as to ensure that the switching module 3 can reliably move to the second detection position along the first direction S2 for the second type of detection. Therefore, the arrangement of the first limiting member 51 and the second limiting member 52 is conducive to ensuring the reliability of the pipeline detection switching device 100 .

[0057] Optionally, in one embodiment, as shown in FIG. 1 and FIG. 2 , the pipeline detection switching device 100 further includes a controller, a first sensor 61 and a second sensor 62, the first sensor 61 and the second sensor 62 are both disposed in the workpiece cavity 1a, the controller is electrically connected to the first sensor 61, the second sensor 62, the first drive assembly 41 and the second drive assembly 42, and the controller can control the first drive assembly 41 to stop driving when the first sensor 61 detects that the switching module 3 enters the first in-position, and control the second drive assembly 42 to start so that the switching module 3 moves along the first direction S2 to the first detection position. The controller can also control the first drive assembly 41 to stop driving when the second sensor 62 detects that the switching module 3 enters the second in-position, and control the second drive assembly 42 to start so that the switching module 3 moves along the first direction S2 to the second detection position. In this way, when the sliding seat 412 drives the switching module 3 to move along the second direction S1 under the drive of the first driving member 411, the first sensor 61 can detect in real time whether the switching module 3 has entered the first in-place position, and the second sensor 62 can detect in real time whether the switching module 3 has entered the first in-place position, and feed back the detection result to the controller in real time, so that when the first sensor 61 detects that the switching module 3 enters the first in-place position, the controller can automatically drive the switching module 3 to move from the first in-place position to the first detection position along the first direction S2 to perform the first type of detection; and when the second sensor 62 detects that the switching module 3 enters the second in-place position, the controller can automatically drive the switching module 3 to move from the second in-place position to the second detection position along the first direction S2 to perform the second type of detection. Therefore, the setting of the first sensor 61 and the second sensor 62 helps the controller to accurately determine whether the switching module 3 has precisely reached the first position and the second position, thereby helping the controller to automatically control the switching module 3 to move from the first position to the first detection position, and from the second position to the second detection position, so as to ensure the effective implementation of the detection. Therefore, this design can improve the automation and reliability of the pipeline detection switching device 100, which is beneficial to improving the detection efficiency.

[0058] Schematically, the position of the controller can be designed as needed. For example, the controller can be set in the workpiece cavity 1a.

[0059] Further, in one embodiment, as shown in FIG. 1 and FIG. 2 , the second driving assembly 42 includes a second driving member 424 and a lifting seat 421 that are drivingly connected, the second driving member 424 is disposed on the first driving assembly 41, and the lifting seat 421 is connected to the switching module 3. Under the drive of the second driving member 424, the lifting seat 421 can drive the switching module 3 to move between the first in-position position and the first detection position along the first direction S2, and can also drive the switching module 3 to move between the second in-position position and the second detection position along the first direction S2. In this way, when the sliding seat 412 drives the switching module 3 to move to the first in-position position under the drive of the first driving member 411, the switching module 3 can move close to the top plate 11 along the first direction S2 under the action of the second driving member 424, so that the switching module 3 can move from the first in-position position to the first detection position to perform the first type of detection. When the detection is completed, the switching module 3 can move away from the top plate 11 along the first direction S2 under the action of the second driving member 424, so that the switching module 3 moves from the first detection position to the first in-place position, so that the switching module 3 can move to the second in-place position along the second direction S1 under the drive of the first driving member 411, and then can move close to the top plate 11 at the second in-place position to move to the second detection position for the second type of detection. Therefore, the pipeline detection switching device 100 can achieve the effect of performing multiple types of tests at the same station, thereby improving detection efficiency.

[0060] Optionally, the second driving member 424 may be a telescopic cylinder.

[0061] Illustratively, the controller is electrically connected to both the first driving member 411 and the second driving member 424 .

[0062] Optionally, in one embodiment, as shown in FIG1 , the second driving assembly 42 further includes a slide bar 423 and a sleeve 422, one end of the slide bar 423 is connected to the lifting seat 421, the other end of the slide bar 423 extends along the first direction S2, and the sleeve 422 is disposed on the second driving member 424, and the sleeve 422 is slidably sleeved on the outer periphery of the slide bar 423. In this way, the stability of the lifting seat 421 when moving along the first direction S2 can be ensured by the sliding cooperation between the sleeve 422 and the slide bar 423, so as to ensure that the lifting seat 421 can reliably drive the switching module 3 to move along the first direction S2, so that the switching module 3 can move between the first in-place position and the first detection position and between the second in-place position and the second detection position, thereby ensuring the reliability of the pipeline detection switching module 3.

[0063] Optionally, as shown in FIG1 , the number of sleeves 422 and the number of slide bars 423 can be multiple, and the multiple slide bars 423 are arranged at intervals along the outer circumference of the lifting seat 421, and the sleeves 422 and the slide bars 423 are slidably connected in a one-to-one correspondence. Preferably, the number of sleeves 422 and the number of slide bars 423 are both two, and the two slide bars 423 are respectively connected to the two sides of the lifting seat 421.

[0064] In one embodiment, as shown in FIG2 , the gas source module 2 further includes a flow meter 23, the gas inlet end of the flow meter 23 is used to communicate with the second detection device, and the gas outlet end of the flow meter 23 is communicated with the second gas inlet 221. In this way, when the second detection device is a flow test device including a gas source, a pressure regulating valve / electrically controlled valve, a pressure gauge, and a valve, when the switching module 3 is located at the second detection position, the second detection device can detect whether the flowability of the workpiece under test meets the requirements through the flow meter 23.

[0065] In one embodiment, in combination with FIGS. 1 to 4 , the opening edge of the first air guide hole 32 is provided with a first seal 321, and the opening edge of the second air guide hole 33 is provided with a second seal 331. In the first detection position and the second detection position, the top plate 11 can be sealed with the first seal 321 and the second seal 331. In this way, when the switching module 3 is in the first detection position and the second detection position, the first seal 321 can block the gap between the surface of the top plate 11 facing the switching module 3 and the opening edge of the first air guide hole 32, and the second seal 331 can block the gap between the surface of the top plate 11 facing the switching module 3 and the opening edge of the second air guide hole 33, so as to avoid gas leakage from the first air guide hole 32 and / or the second air guide hole 33 to the external environment during the detection process, thereby ensuring the reliability of the detection result of the pipeline detection switching module 3.

[0066] Schematically, the first sealing member 321 and the second sealing member 331 are both O-type sealing rings, wherein the O-type sealing ring has the characteristic of being able to perform plane sealing. In this way, during the movement of the switching module 3 along the first direction S2 to approach the top plate 11, when the switching module 3 is about to reach the first detection position, the surface of the top plate 11 opposite to the switching module 3 can contact and squeeze the first seal 321 and the second seal 331, so that the first seal 321 can seal the first air guide hole 32 and the first connecting hole 111, and the surface of the top plate 11 can reliably block the second air guide hole 33 through the second seal 332, so as to avoid affecting the reliability of the detection result due to air leakage of the second air guide hole 33 during the first type of detection; similarly, when the switching module 3 is about to reach the second detection position, the surface of the top plate 11 opposite to the switching module 3 can contact and squeeze the first seal 321 and the second seal 331, so that the second seal 331 can seal the second air guide hole 33 and the second connecting hole 112, and the surface of the top plate 11 can reliably close the first air guide hole 32 through the first seal 321, so as to ensure the reliability of the second type of detection.

[0067] In one embodiment, the first gas source block 21 is provided with an inlet valve 212 and an exhaust valve 213, and both the inlet valve 212 and the exhaust valve 213 are connected between the first inlet port 211 and the first outlet port. In this way, during the first type of detection, the on-off of the first detection circuit can be controlled by the inlet valve 212, so that the gas can be controlled to enter the workpiece under test through the inlet valve 212. After the detection is completed, the gas in the workpiece under test can be discharged through the exhaust valve 213, so that the workpiece under test can be tested for the next test.

[0068] Schematically, the intake valve 212 and the exhaust valve 213 are used to be electrically connected to the first detection device, so that when the first detection device is started to perform the first type of detection, the intake valve 212 can be automatically turned on to automatically complete the first type of detection. When the first type of detection is completed, the exhaust valve 213 can automatically open the exhaust operation under the control of the first detection device.

[0069] Further, in one embodiment, in combination with FIGS. 1 to 4, the number of the first air outlets, the number of the second air outlets, the number of the second air inlets 221, the number of the first connecting holes 111, the number of the second connecting holes 112, the number of the air receiving holes 31, the number of the first air guide holes 32, and the number of the second air guide holes 33 are all multiple, each first air outlet can be connected to the first air inlet 211, and an air intake valve 212 and an exhaust valve 213 are provided between each first air outlet and the first air inlet 211, and the first air outlet and the first air inlet 211 are connected to each other. The connecting holes 111 are connected in one-to-one correspondence, the second air outlet is connected in one-to-one correspondence with the second air inlet 221 and the second connecting hole 112, the air receiving hole 31 is connected in one-to-one correspondence with the first air guide hole 32 and the second air guide hole 33, in the first detection position, the first connecting hole 111 is connected in one-to-one correspondence with the first air guide hole 32, and the top plate 11 can close a plurality of second air guide holes 33, in the second detection position, the second connecting hole 112 is connected in one-to-one correspondence with the second air guide hole 33, and the top plate 11 can close a plurality of first air guide holes 32. In this way, the pipeline detection switching device 100 can detect a plurality of workpieces to be detected at a time, thereby improving the detection work efficiency.

[0070] Among them, the number of first air inlets 211 can be set as needed. For example, the number of first air inlets 211 is multiple, and the first air inlets 211 are connected to the first air outlets one-to-one, and each first air inlet 211 is connected to a first detection device. In this way, the first detection device can perform the first type of detection on the workpiece to be measured one-to-one; or, the number of first air inlet 211 can be only one, and multiple first air inlets 211 are connected to the same first detection device. In this way, the first detection device can first perform the first type of detection on multiple workpieces to be measured at the same time, so as to determine whether the multiple workpieces to be measured meet the detection requirements based on the detection results. If the detection results find that the detection requirements are not met, the single workpiece to be measured is detected through the cooperation of the first detection device and the air inlet valve 212 and the exhaust valve 213 to determine which workpieces to be measured do not meet the requirements.

[0071] Optionally, in one embodiment, in combination with FIGS. 1 to 4, the number of first air outlets, the number of second air outlets, the number of second air inlets 221, the number of first connecting holes 111, the number of second connecting holes 112, the number of air receiving holes 31, the number of first air guide holes 32, and the number of second air guide holes 33 are all four, the number of first air inlets 211 is two, one first air inlet 211 is connected to two of the first air outlets, and the other first air inlet 211 is connected to the other two first air outlets, and an air intake valve 212 and an air exhaust valve 213 are provided between each first air outlet and the corresponding first air inlet 211. In this way, the pipeline detection switching device 100 can detect four workpieces to be detected each time, thereby improving the detection work efficiency. Among them, when performing the first type of inspection on the workpiece to be tested, the first inspection device first simultaneously inspects the corresponding two workpieces to be tested. If the inspection finds that there are problems that do not meet the inspection requirements, the first inspection device is able to separately inspect one of the workpieces to be tested by opening and closing the intake valve 212 and the exhaust valve 213 to confirm the workpiece to be tested that does not meet the inspection requirements.

[0072] In conjunction with FIG. 1 to FIG. 3 , the present application further provides a pipeline detection method, which uses the pipeline detection switching device 100 in any of the above embodiments to perform detection, and includes the following steps:

[0073] S1: The moving module 4 drives the switching module 3 to move to the first detection position. In this way, the first air guide hole 32 in the switching module 3 can be connected with the first connecting hole 111, and the second air guide hole 33 can be closed, so that the workpiece to be tested can be connected with the first air outlet in the first air source block 21, so that the workpiece to be tested can form a complete detection circuit with the first detection device, so as to facilitate the first type of detection.

[0074] S2: The first detection device performs a first type of detection on the workpiece. Thus, when the first detection device is started, gas can enter the workpiece through the first gas inlet 211, so that the first detection device can detect the workpiece and determine whether the workpiece meets the requirements of the first type of detection based on the detection results.

[0075] S3: The moving module 4 drives the switching module 3 to move to the second detection position. In this way, the second air guide hole 33 in the switching module 3 can be connected with the second connecting hole 112, and the second air guide hole 33 can be closed, so that the workpiece to be tested can be connected with the second air outlet in the second air source block 22, so that the workpiece to be tested can form a complete detection circuit with the second detection device, so as to facilitate the second type of detection.

[0076] S4: The second detection device performs a second type of detection on the workpiece. In this way, the first detection device can allow gas to enter the workpiece through the second air inlet 221, so that the second detection device can detect the workpiece and determine whether the workpiece meets the requirements of the second type of detection based on the detection results.

[0077] In the above pipeline detection method, since the switching module 3 can not only move to the first detection position but also move from the first detection position to the second detection position under the drive of the moving module 4, and the first detection device can perform the first type of detection on the workpiece under test at the first detection position, and the second detection device can perform the second type of detection on the workpiece under test at the second detection position, the switching module 3 can be used as an intermediate bridge, so that the workpiece under test can be connected to the first detection device and the second detection device respectively, so that the workpiece under test can switch between the first type of detection and the second type of detection, thereby realizing multiple types of detection of the workpiece under test. Therefore, through the pipeline detection method, the workpiece under test can complete multiple types of detection at the same station, thereby avoiding the workpiece disassembly and assembly operations increased by switching stations, and effectively improving the detection efficiency.

[0078] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
