Description

Technical Field

[0001] This application relates to the technical field of water pump production, and particularly to a semi-automatic assembly and testing system for water pumps. Background Art

[0002] A water pump may include an electric motor and a hydraulic component. The hydraulic component includes a pump casing, an impeller, etc. During the production process of the water pump, the electric motor and the hydraulic component can be separately sub-assembled first, that is, the electric motor and the hydraulic component are respectively assembled and formed; subsequently, the electric motor and the hydraulic component are assembled together, that is, the electric motor and the hydraulic component are connected. When the water pump assembly is completed, the water pump usually also needs to be subjected to relevant tests, including but not limited to airtightness tests and electrical performance tests. When the airtightness test is qualified, the water pump usually also needs to be oiled. And at the electrical performance test station, a water pump cable is externally connected to test items such as grounding, coil resistance, phase-to-phase resistance difference, and withstand voltage of the water pump. In the prior art, the water pump is usually first assembled on an assembly line and then further relevant tests are carried out on a test line. Since the production efficiency during assembly is usually high, while the production efficiency during testing is low, especially when there are many electrical performance test items and the test takes a long time, the production beats of the two processes of assembly and testing do not match. In the prior art, it is often necessary to adopt a method of temporarily storing the assembled water pump to control the production beat, such as setting up a temporary storage device for transfer and temporary storage between the assembly line and the test line. However, since the temporary storage involves multiple loading and unloading of the water pump, it is not only time-consuming and laborious, inconvenient, but also increases the complexity of the production line and raises the cost. Summary of the Invention

[0003] Based on this, this application provides a semi-automatic assembly and testing system for water pumps to improve the problems in the prior art that a temporary storage device is set between the assembly line and the test line for transferring and temporarily storing the assembled water pump, resulting in inconvenience in the production process, an increase in the complexity of the production line, and an increase in cost.

The front side slide plate is arranged in parallel with both the first slide plate and the second slide plate, and the front side slide plate is connected to the front side driving mechanism.

The rear slide plate is arranged in parallel with both the first slide plate and the second slide plate, and the rear slide plate is connected to the rear drive mechanism.

[0031] An embodiment of the present application provides a semi-automatic assembly and testing system for a water pump, as Figures 1 to 3 shown. The semi-automatic assembly and testing system for a water pump includes:

[0032] A carrier tooling 100;

[0033] A rotary line body. The carrier tooling 100 is slidably arranged on the rotary line body in a first rotary direction. The rotary line body includes a first line body 200, a second line body 300, a front rotary line body 400, and a rear rotary line body 500. The first line body 200 and the second line body 300 are arranged in parallel. The front rotary line body 400 is arranged between the downstream side of the first line body 200 and the upstream side of the second line body 300. The rear rotary line body 500 is arranged between the upstream side of the first line body 200 and the downstream side of the second line body 300;

[0034] An airtightness testing device 600, which is arranged at the corresponding position of the first line body 200;

[0035] An oil injection device;

[0036] An electrical performance testing device 700, which is arranged at the corresponding position of the front rotary line body 400;

[0037] Wherein, when the carrier tooling 100 moves to the first line body 200, the motor and the hydraulic components are assembled into a water pump on the carrier tooling 100. The airtightness testing device 600 conducts an airtightness test on the water pump. When the airtightness test of the water pump is qualified, the oil injection device injects oil into the water pump;

[0038] When the carrier tooling 100 continues to move to the second line body 300, the electrical performance testing device 700 conducts an electrical performance test on the water pump;

[0039] When the electrical performance test of the water pump is completed, the carrier tooling 100 continues to move from the second line body 300 and the rear rotary line body 500 to the first line body 200.

[0040] As Figure 1 and Figure 2As shown, in this embodiment, by way of example, the vehicle tooling 100 can be rotatably arranged on the rotary line body. When the vehicle tooling 100 moves, it can sequentially move to the first line body 200, the front rotary line body 400, the second line body 300, and the rear rotary line body 500, and cycle in this order. The rotary direction formed by the vehicle tooling 100 in this order is the first rotary direction, and the upstream and downstream of the line body are distinguished by this direction. The first line body 200, the front rotary line body 400, the second line body 300, and the rear rotary line body 500 can be arranged within a rectangular area. The first line body 200 and the second line body 300 can be arranged along the length direction of the rectangle, while the front rotary line body 400 and the rear rotary line body 500 can be arranged along the width direction of the rectangle. On the first line body 200, the front rotary line body 400, the second line body 300, and the rear rotary line body 500, components such as profiles and plates can be arranged to form a frame 800, so as to facilitate the arrangement of devices such as the airtightness testing device 600, the oil injection device, and the electrical performance testing device 700, and facilitate the arrangement of a relatively safe enclosed space required for electrical performance testing. The airtightness testing device 600 can be connected to the frame 800 and arranged directly above the first line body 200; the oil injection device (not shown in the figure) can be arranged on one side of the frame 800. The oil injection device can include an oil injection gun and an oil barrel. The oil injection gun can be connected to the oil barrel to pump out the oil in the oil barrel; while the electrical performance testing device 700 can be connected to the frame 800 and arranged directly above the front rotary line body 400.

[0041] Of course, in some embodiments, the electrical performance testing device 700 can also be arranged directly above the front rotary line body 400 on the side close to the first line body 200.

[0042] When the vehicle tooling 100 moves to the first line body 200, the motor and the hydraulic components can be assembled into a water pump on the vehicle tooling 100. After the assembly is completed, the airtightness testing device 600 can perform an airtightness test on the water pump. The airtightness testing device 600 can be an airtightness tester. The airtightness testing device 600 can record, display, store the test results and judge whether it passes. If it passes, it enters the next step of oil injection; if it does not pass, it alarms until the alarm signal is manually eliminated. In other words, when the airtightness test of the water pump is qualified, the oil injection device can inject a fixed amount of oil into the water pump. When the airtightness test of the water pump is unqualified, the water pump can be repaired immediately on the vehicle tooling 100.

[0043] Of course, in some embodiments, when the airtightness test of the water pump is unqualified, the water pump with unqualified airtightness test can also be taken offline for subsequent unified repair.

[0044] Such as Figure 1 and Figure 2As shown, when the vehicle tooling 100 is moved from the first line 200 to the front side of the rotary line 400, the vehicle tooling 100 can further move the water pump that has passed the airtightness test to directly below the electrical performance test device 700, so as to facilitate the electrical performance test device 700 to perform electrical performance tests on the water pump. The items of electrical performance tests can include but are not limited to: visual recognition anti-error, grounding, coil resistance, phase-to-phase resistance difference, withstand voltage, no-load current, and motor rotation direction, etc. The electrical performance test device 700 can also record, display, store the test results and judge whether it passes. If it does not pass, it will alarm until the alarm signal is manually eliminated; if a certain test fails, you can choose to exit the test, then no report will be generated, or after adjustment, you can choose to retest. If the test is successful, it will overwrite the original unqualified test results and continue downward. The rack 800 can be provided with an openable and closable cabinet door at the electrical performance test device 700. When the water pump is undergoing electrical performance tests, the cabinet door can be closed to improve the safety of the test. And when the vehicle tooling 100 is moved from the first line 200 to the front side of the rotary line 400, the cabinet door can be opened to make way for the vehicle tooling 100.

[0045] After all the items of electrical performance tests are completed, the vehicle tooling 100 can continue to move from the front side of the rotary line 400 to the second line 300 and the rear side of the rotary line 500, and can then be offline when moving back to the first line 200 again.

[0046] It can be understood that since the present application arranges the two processes of assembly and testing in the production process of the water pump on the rotary line, the present application can make the two processes of assembly and testing proceed continuously and cyclically. And when arranging the devices corresponding to the testing process, by arranging the relatively time-consuming electrical performance test on the front side of the rotary line 400 and arranging the relatively time-consuming airtightness test on the first line 200, the present application can complete the airtightness test along with the assembly process, so as to realize the redistribution of the production rhythm, that is, the total production efficiency of the airtightness test and assembly can basically match the production efficiency of the airtightness test, thereby avoiding the arrangement of temporary storage equipment for transfer and temporary storage.

[0047] In summary, the present application can avoid the multiple loading and unloading of the water pump involved in temporary storage, and the production process is more convenient and fast; at the same time, the present application also reduces the complexity of the production line and avoids the increase in costs caused by the investment of a large number of automated equipment, etc.

[0048] Specifically, the vehicle tooling 100 includes a sliding base 110 and a fixture 120. The sliding base 110 is slidably arranged on the rotary line, and the fixture 120 is arranged on the sliding base 110. The fixture 120 is used to clamp the motor or the water pump.

[0049] As Figure 2 andFigure 3 As shown, in this embodiment, by way of example, the sliding base 110 can be configured as a trolley shape, and rollers 111 can be provided on the sliding base 110. The sliding base 110 can be in contact with the rotary line body through the rollers 111. The sliding base 110 can be configured as a cuboid shape. The rollers 111 can be embedded on one side of the sliding base 110 in the width direction, and the fixture 120 can be provided on the other side of the sliding base 110. A support plate 112 can be provided on one side of the sliding base 110 close to the fixture 120, and the fixture 120 can be provided on the top of the support plate 112. When the sliding base 110 moves, the rollers 111 can rotate on the rotary line body to reduce the frictional resistance when the sliding base 110 moves, thereby enabling the sliding base 110 to move smoothly. When the sliding base 110 moves, it can drive the fixture 120 to move synchronously. When the sliding base 110 moves on the first line body 200, it can clamp the motor to facilitate the assembly of the motor and the water conservancy components. When the sliding base 110 moves to the front rotary line body 400, the second line body 300, and the rear rotary line body 500, it clamps the water pump. Of course, the component of the fixture 120 for clamping the water pump is also the motor.

[0050] It can be understood that through the reasonable setting of the structure of the carrier tooling 100 in this embodiment, it is not only convenient to realize the rotary movement of the carrier tooling 100 on the rotary line body, but also convenient to fix the motor or the water pump, so as to facilitate the assembly and testing processes.

[0051] More specifically, the first line body 200 includes a first slide plate 210, the second line body 300 includes a second slide plate 310 and a base driving mechanism 320. The first slide plate 210 and the second slide plate 310 are arranged in parallel. The sliding base 110 is slidably arranged on the first slide plate 210 or the second slide plate 310. The base driving mechanism 320 is connected to the sliding base 110 and drives the sliding base 110 to move on the second slide plate 310.

[0052] As Figure 2As shown, in this embodiment, by way of example, the first sliding plate 210 and the second sliding plate 310 can both be arranged as flat plates and can both be arranged vertically. When the sliding base 110 moves onto the first sliding plate 210 or the second sliding plate 310, the first sliding plate 210 or the second sliding plate 310 can pass through the sliding base 110, and the rollers 111 of the sliding base 110 can be distributed on both sides of the first sliding plate 210 or the second sliding plate 310 and abut against the first sliding plate 210 or the second sliding plate 310. The first sliding plate 210 and the second sliding plate 310 are arranged vertically, which can prevent the first sliding plate 210 and the second sliding plate 310 from being bent and deformed due to excessive load, thereby ensuring the smooth movement of the sliding base 110 and at the same time ensuring the accuracy of the moving position of the sliding base 110. The first sliding plate 210 and the second sliding plate 310 can both be arranged on the frame 800 through the inverted "L"-shaped bracket unit 810 for convenient suspended arrangement.

[0053] As Figure 2 and Figure 3 shown, in this embodiment, the movement of the sliding base 110 on the first sliding plate 210 can be manually driven, that is, manually push the sliding base 110 to make it move on the first sliding plate 210. At this time, the assembly of the motor and the hydraulic components can be manual assembly, which can further reduce the investment and use of automated equipment on the premise of affecting the production efficiency of the entire line body to reduce costs. It should be noted that during the assembly process of the motor and the hydraulic components, there are usually some steps that inevitably need to be completed manually, and these steps cannot or are inconvenient to be completed by automated equipment. The movement of the sliding base 110 on the second sliding plate 310 can be automatically driven, that is, the sliding base 110 is driven to move on the second sliding plate 310 by the base drive mechanism 320. The sliding base 110 adopting an automated driving method on the second line body 300 without assembly and testing can make the sliding base 110 rotate back to the first line body 200 faster to ensure production efficiency.

[0054] It can be understood that in this embodiment, by reasonably setting the structures and driving methods of the first line body 200 and the second line body 300, the investment in automated equipment can be minimized on the premise of ensuring production efficiency, thereby reducing costs and at the same time avoiding an increase in the complexity of the production line.

[0055] More specifically, a transmission gear 113 is provided on the sliding base 110. The transmission gear 113 is rotatably arranged. The base drive mechanism 320 includes a drive chain assembly 330 and a drive motor 340. The drive motor 340 is in transmission with the drive chain assembly 330, and the transmission gear 113 is in transmission with the drive chain assembly 330 and is slidably arranged on the drive chain assembly 330.

[0056] As Figure 2 andFigure 3 As shown, in this embodiment, the transmission tooth 113 can be rotatably arranged just above the roller 111 of the sliding base 110, so that the drive chain assembly 330 can be driven on the transmission tooth 113. The drive chain assembly 330 may include a driving tooth 331, a driven tooth 332 and a transmission chain 333. The driving tooth 331 can be driven with the output end of the driving motor 340, for example, it is sleeved on the output end of the driving motor 340, and the driving motor 340 can be connected to the frame 800. The driving tooth 331 can be driven with the driven tooth 332 through the transmission chain 333. When the driving tooth 331 rotates, it drives the driven tooth 332 to rotate synchronously, and the transmission chain 333 moves back and forth. Two driven teeth 332 can be provided, and they are arranged on both sides of the driving tooth 331. The driving tooth 331 can be staggered with the connecting line of the two driven teeth 332, and the transmission chain 333 can be tensioned by an idler wheel. The driving chain assembly 330 may be disposed on a side of the second slide plate 310 away from the first slide plate 210 , and a side of the driving chain 333 close to the second slide plate 310 may extend along a length direction of the second slide plate 310 .

[0057] like Figure 2 and Figure 3 As shown, in this embodiment, when the sliding base 110 is close to the second slide plate 310, the transmission teeth 113 on the sliding base 110 can just mesh with the transmission chain 333 to perform transmission. When the output end of the driving motor 340 rotates to make the transmission chain 333 reciprocate, the transmission chain 333 can drive the transmission teeth 113 to rotate, and the transmission teeth 113 can move on the transmission chain 333, so that the sliding base 110 moves from the rotating front side line body 400 to the second slide plate 310, and at the same time, the automatic movement on the second slide plate 310 is realized.

[0058] It is understandable that, in this embodiment, by providing the transmission teeth 113 on the sliding base 110 and rationally arranging the structure of the base driving mechanism 320 , the base driving mechanism 320 can drive the transmission teeth 113 to achieve smooth movement of the sliding base 110 on the second slide 310 .

[0059] Specifically, the rotating front side line body 400 includes a front side skateboard 410 and a front side driving mechanism 420. The front side skateboard 410 is arranged parallel to the first skateboard 210 and the second skateboard 310, and the front side skateboard 410 is connected to the front side driving mechanism 420. The front side driving mechanism 420 drives the front side skateboard 410 to move between the first skateboard 210 and the second skateboard 310.

[0060] like Figure 1 and Figure 2As shown, in this embodiment, by way of example, the front drive mechanism 420 may be a linear module, whose guide rail may extend along the width direction of the frame 800, and whose slider may be slidably arranged along the width direction of the frame 800. The front slide plate 410 may be connected to the slider through the aforementioned inverted "L"-shaped bracket unit 810. When the slider slides, the slider can drive the front slide plate 410 to move synchronously. The movement track of the front slide plate 410 is between the first slide plate 210 and the second slide plate 310. When the front slide plate 410 is flush with the first slide plate 210, the sliding base 110 can move from the first slide plate 210 to the front slide plate 410. Subsequently, the slider can drive the front slide plate 410 to move in the direction approaching the second slide plate 310. When the front slide plate 410 is flush with the second slide plate 310, the sliding base 110 can move from the front slide plate 410 to the second slide plate 310. It is not difficult to understand that when the front slide plate 410 moves between the first slide plate 210 and the second slide plate 310, it can also move directly below the electrical performance testing device 700 and stop directly below the electrical performance testing device 700 for electrical performance testing.

[0061] It can be understood that through the reasonable setting of the structure of the rotary front line body 400 in this embodiment, it is convenient to realize the movement of the sliding base 110 from the first slide plate 210 to the second slide plate 310, and at the same time, it is convenient to move the water pump directly below the electrical performance testing device 700 for electrical performance testing.

[0062] More specifically, the rotary rear line body 500 includes a rear slide plate 510 and a rear drive mechanism 520. The rear slide plate 510 is arranged parallel to both the first slide plate 210 and the second slide plate 310, and the rear slide plate 510 is connected to the rear drive mechanism 520. The rear drive mechanism 520 drives the rear slide plate 510 to move between the first slide plate 210 and the second slide plate 310.

[0063] As Figure 2As shown, in this embodiment, by way of example, similarly, the rear drive mechanism 520 can also be a linear module, which can be arranged in parallel with the front drive mechanism 420 and is arranged on the other side of the first slide plate 210 and the second slide plate 310. Similarly, the rear slide plate 510 can also be connected to the slider of the rear drive mechanism 520 through the bracket unit 810. When the slider of the rear drive mechanism 520 slides, the slider can drive the rear slide plate 510 to move synchronously. The movement trajectory of the rear slide plate 510 is also between the first slide plate 210 and the second slide plate 310. When the rear slide plate 510 is flush with the second slide plate 310, the sliding base 110 can move from the second slide plate 310 to the rear slide plate 510. Subsequently, the slider can drive the rear slide plate 510 to move in the direction approaching the first slide plate 210. When the front slide plate 410 is flush with the first slide plate 210, the sliding base 110 can move from the rear slide plate 510 to the first slide plate 210.

[0064] It can be understood that in this embodiment, through the reasonable setting of the structure of the rotary rear line body 500, it is convenient to realize the movement of the sliding base 110 from the second slide plate 310 to the first slide plate 210 to realize the rotary movement of the sliding base 110.

[0065] More specifically, positioning mechanisms 900 are provided on both the front slide plate 410 and the rear slide plate 510. The positioning mechanism 900 includes a positioning pin 910 which is slidably arranged. The positioning pin 910 is connected to the sliding base 110 to fix the sliding base 110 on the front slide plate 410 or the rear slide plate 510.

[0066] As Figure 2 and Figure 3 shown, in this embodiment, by way of example, the positioning mechanism 900 can further include a positioning drive cylinder 920. The positioning drive cylinder 920 can be arranged on the bracket unit 810, and the positioning pin 910 can be arranged at the output end of the positioning drive cylinder 920. When the output end of the positioning drive cylinder 920 expands and contracts, it can drive the positioning pin 910 to move synchronously. A pin hole 114 for the positioning pin 910 to extend into can be provided on the sliding base 110. When the sliding base 110 moves to the front slide plate 410 or the rear slide plate 510, the positioning drive cylinder 920 can extend the positioning pin 910 into the pin hole 114 to fix the sliding base 110 on the front slide plate 410 or the rear slide plate 510. When it is necessary to drive the sliding base 110 to move on the front slide plate 410 or the rear slide plate 510, the positioning drive cylinder 920 can withdraw the positioning pin 910 from the pin hole 114.

[0067] It can be understood that in this embodiment, by providing the positioning mechanism 900 to fix the sliding base 110 on the front side slide plate 410 and the rear side slide plate 510, the sliding base 110 can be kept stable when moving between the first slide plate 210 and the second slide plate 310, thereby facilitating the rotary movement of the sliding base 110; at the same time, when the sliding base 110 moves to directly below the electrical performance testing device 700, it is convenient to ensure the accuracy of the test, especially to ensure the accuracy of the tests related to visual testing.

[0068] Specifically, the fixture 120 includes clamping arms 121 and a locking mechanism 122. There are two clamping arms 121 arranged in an opposing manner, and at least one clamping arm 121 is rotatably arranged. The locking mechanism 122 is connected to the two clamping arms 121 and locks and fixes the two clamping arms 121.

[0069] As Figure 2 and Figure 3 shown, in this embodiment, by way of example, the clamping arm 121 can be arranged in a semi-circular shape and can clamp the outside of the motor. A cushion layer can be arranged on the side of the clamping arm 121 for clamping, and the cushion layer can be made of a flexible material to increase the friction and avoid rigid contact with the outside of the motor. The two clamping arms 121 can both be rotatably arranged to facilitate arranging the motor between the two clamping arms 121. Of course, only one of the clamping arms 121 can be rotatably arranged while the other is fixedly arranged. This embodiment takes the latter as an example. The locking mechanism 122 is connected to the two clamping arms 121 and is used to lock and fix the two clamping arms 121. When the locking mechanism 122 is loosened, the rotatably arranged clamping arm 121 can rotate. The locking mechanism 122 can be a latch-type quick clamp for easy operation.

[0070] It can be understood that in this embodiment, through the reasonable setting of the structure of the fixture 120, it is easy to realize the clamping and fixing of the motor, so as to assemble the motor and the hydraulic components into a water pump, and at the same time facilitate the testing of the assembled water pump.

[0071] Specifically, the fixture 120 is rotatably arranged on the sliding base 110. The carrier tooling 100 further includes a plug-in member. The plug-in member passes through the sliding base 110 and is connected to the fixture 120, and limits the rotation of the fixture 120.

[0072] As Figure 2 and Figure 3As shown, in this embodiment, by way of example, a rotating seat 115 may be provided on the sliding base 110, and the fixture 120 may be rotatably arranged in the rotating seat 115 through a rotating shaft. The rotating shaft of the fixture 120 may be perpendicular to the axis of the motor. When the fixture 120 rotates on the sliding base 110, it can move the axis of the motor to different positions, such as keeping the axis of the motor vertical, horizontal, etc. The plugging member (not shown in the figure) may be set as a manually inserted and removed rod, and the plugging member can pass through the rotating seat 115 and extend into the rotation to limit the rotation of the fixture 120; corresponding through holes 116 may be provided on the rotating seat 115.

[0073] It can be understood that in this embodiment, by rotatably arranging the fixture 120 and limiting the rotation of the fixture 120 through the plugging member, the motor or the water pump can be rotated to different angles by rotating the fixture 120, so as to facilitate assembly and testing. For example, when the oil injection hole is perpendicular to the axis of the motor, the axis of the motor can be rotated to the horizontal to make the oil injection hole face upward, thereby facilitating oil injection; for another example, when the relevant items of the electrical performance test involve the switching of the axis of the motor.

[0074] More specifically, a damping is provided at the rotational connection between the fixture 120 and the sliding base 110.

[0075] As Figure 2 and Figure 3 shown, in this embodiment, by way of example, the damping may be made of an elastic material, such as rubber, silica gel or resin, etc. The damping may be sleeved on the rotating shaft of the fixture 120 and extend into the rotating seat 115. The damping can increase the frictional resistance at the rotational connection between the fixture 120 and the sliding base 110 to prevent the fixture 120 from rotating instantaneously under the self-weight of the motor or the water pump and causing an impact when the plugging member is removed.

[0076] The implementation principle of a semi-automatic assembly and test system for a water pump provided by an embodiment of the present application is as follows:

[0077] During the production process, when the sliding base 110 moves onto the first slide plate 210, the motor can be clamped and fixed by the fixture 120, and then the motor and the hydraulic components are assembled into a water pump. After the assembly is completed, the water pump can be subjected to an airtightness test by the airtightness test device 600. When the airtightness test of the water pump is qualified, the water pump can be quantitatively oiled by the oil injection device. After the oil injection is completed, the sliding base 110 can be manually driven to move from the first slide plate 210 to the front slide plate 410. When the sliding base 110 moves onto the front slide plate 410, the positioning drive cylinder 920 on the front slide plate 410 drives the positioning pin 910 to extend into the pin hole 114 of the sliding base 110 to fix the sliding base 110. Subsequently, the sliding base 110 is moved to directly below the electrical performance test device 700 by the front drive mechanism 420, and the electrical performance of the water pump is tested by the electrical performance test device 700. When all the items of the electrical performance test are completed, the front slide plate 410 can continue to approach the second slide plate 310. When the front slide plate 410 is flush with the second slide plate 310, the transmission gear 113 on the sliding base 110 can just engage with the transmission chain 333. At this time, the positioning drive cylinder 920 can drive the positioning pin 910 to withdraw from the pin hole 114, and then drive the output end of the drive motor 340 to rotate so that the transmission chain 333 reciprocates. The transmission chain 333 can drive the transmission gear 113 to rotate, and the transmission gear 113 can move on the transmission chain 333 so that the sliding base 110 moves from the front rotary line body 400 to the second slide plate 310 and further moves on the second slide plate 310. After that, the sliding base 110 can continue to move from the rear rotary line body 500 to the first line body 200 again, and at this time, the assembled and tested water pump can be taken off the production line.

[0078] Since this application arranges the two processes of assembly and testing in the production process of the water pump on the rotary line body, this application can make the two processes of assembly and testing proceed continuously and cyclically. When arranging the devices corresponding to the testing process, by arranging the electrical performance test, which takes a relatively long time, on the front rotary line body 400 and arranging the airtightness test, which takes a relatively short time, on the first line body 200, this application can complete the airtightness test along with the assembly process to reallocate the production rhythm, that is, the total production efficiency of the airtightness test and assembly can basically match the production efficiency of the airtightness test, thereby avoiding the need to arrange temporary storage equipment for transfer and temporary storage.

[0079] In summary, this application can avoid the multiple loading and unloading of the water pump involved in temporary storage, and the production process is more convenient and fast; at the same time, this application also reduces the complexity of the production line and avoids the cost increase caused by the investment of a large number of automated devices.

[0080] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, 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, it should be considered as the scope described in this specification.

[0081] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
