Description

Technical Field

[0001] This invention relates to the field of automated processing equipment for foam pumps, specifically to a fully automated continuous testing device for foam pump bodies. Background Technology

[0002] Nowadays, people are paying more and more attention to their health and hygiene. In order to keep their bodies clean, people are now used to using some cleaning liquids when washing their hands, face, or taking a bath. To meet people's needs, a large number of facial cleansers, hand soaps, shower gels, and other cleaning liquids have appeared on the market. In order to make them convenient to use, foam pumps have emerged. When in use, you can output foamy fluid by pressing the nozzle, which is convenient for people to use.

[0003] Currently, after assembling a foam pump, it is necessary to test its pressure, liquid feeding performance, and airtightness to ensure its quality. Existing testing equipment mostly involves separate testing processes, making simultaneous testing impossible and requiring manual operation. Chinese patent CN111982429B discloses a foam pump body testing device, including a frame with a liquid feeding testing mechanism, an internal pressure testing mechanism, and a negative pressure testing mechanism arranged linearly on it. A conveying mechanism is also provided on the frame, with a discharge fixture on the conveying mechanism. The foam pump body is placed on the discharge fixture, and the conveying mechanism drives the foam pump body through the liquid feeding testing mechanism, the internal pressure testing mechanism, and the negative pressure testing mechanism. After sealing at the top and bottom of each mechanism, gas is pumped in, and the pump body is pressed down to test the gas output, the air compression density inside the cylinder, and the negative pressure and sealing performance are tested during vacuuming.

[0004] However, when using this equipment, the foam pump needs to stop at different testing stations for varying durations, resulting in time differences. This necessitates frequent starting and stopping of the conveying mechanism, affecting its lifespan and creating downtime between testing stations, thus impacting overall testing efficiency. Summary of the Invention

[0005] To address the aforementioned issues, it is necessary to provide a fully automated continuous testing device for foam pump bodies, addressing the problems inherent in existing technologies.

[0006] To solve the problems of the prior art, the technical solution adopted by the present invention is as follows:

[0007] A fully automatic continuous testing device for foam pump bodies includes a conveying track with a feeding device and a discharging device connected to its two ends. The pump body moves within the conveying track, and several testing devices are arranged along the extended path of the conveying track. The conveying track includes two horizontally extending straight channels on the same straight line, and several semi-circular arc-shaped channels are arranged between the straight channels, which are connected end-to-end in an "S" shape. A synchronous rotating seat is arranged at the axial position of each arc-shaped channel, and several functionally identical testing devices are evenly distributed around the periphery of each synchronous rotating seat. The synchronous rotating seat drives the testing devices to rotate around the axis of the arc-shaped channel. The testing device includes an upper sealing element for sealing the upper end of the pump body and a lower sealing element for sealing the lower end of the pump body. The upper and lower sealing elements are coaxially mounted on the working end of a first linear actuator. The first linear actuator drives the upper and lower sealing elements to clamp the pump body and move along the conveying track following the rotation of the testing device. The testing device completes the testing during the movement of the pump body.

[0008] Preferably, both the upper and lower seals have an inner cavity and an opening facing one end of the pump body. A rubber sleeve is provided inside the opening, and the rubber sleeve contacts the outer wall of the pump body to seal the pump body. At least one side air passage is provided on the upper and lower seals, extending radially along the axis of the upper and lower seals. The side air passage is connected to the detection device through a flexible pipe.

[0009] Preferably, two first linear actuators for mounting the upper and lower seals on the same axis are fixedly mounted at the upper and lower ends of the fixed base, respectively. The fixed base extends vertically, and the working ends of the two first linear actuators are arranged opposite each other. The fixed base is slidably mounted on the synchronous rotating base, and the fixed base moves radially along the axis of the synchronous rotating base.

[0010] Preferably, a scrap channel is provided on the arc-shaped channel, which is located on the side of the arc-shaped channel away from the material end of the conveying track and extends inward into the arc-shaped channel; a lane-changing unit is provided at the connection between the arc-shaped channel and the scrap channel, which changes the movement path of the pump body so that the detection device drives the pump body that fails the detection to the scrap channel.

[0011] Preferably, the lane-changing unit includes a stop block, which is inserted into one side of the connection between the arc-shaped channel and the waste channel. The rotation axis of the stop block is vertically set, and the inner side of the stop block has a guide surface that can be tangent to the arc-shaped channel and the waste channel. The stop block is driven to the working end of the rotary driver, which is fixedly installed on one side of the arc-shaped channel.

[0012] Preferably, the synchronous rotating seat includes an inner hollow outer cylinder, the axis of which is on the same straight line as the axis of the arc-shaped channel; the outer cylinder is connected to a rotary drive unit, which is fixedly mounted on the base.

[0013] Preferably, a guide plate extending horizontally in the radial direction of the outer cylinder axis is provided on the side of the fixed base facing the outer cylinder. The guide plate is inserted into a guide sleeve provided on the periphery of the outer cylinder. The guide sleeve has a cross-section with the same shape as the guide plate. A second linear actuator is fixedly installed on one side of the guide sleeve. The working end of the second linear actuator is located facing the fixed base. The working end of the second linear actuator moves along the length direction of the guide sleeve. The detection device is connected to the second linear actuator through a controller signal.

[0014] Preferably, a limiting rod protruding from the surface of the guide plate is provided on one side of the guide plate. The limiting rod is inserted into a waist-shaped hole provided on the guide sleeve. The waist-shaped hole extends along the length direction of the guide sleeve. When the limiting rod is located at the farthest end of the waist-shaped hole, the upper seal and the lower seal are on the same straight line as the pump body on the arc-shaped channel.

[0015] Preferably, the base of the synchronous rotating seat is provided with an inner rod extending vertically upward along the axis of the outer cylinder, the outer cylinder is sleeved on the inner rod, and a first signal generator and a second signal generator are respectively provided on the top of the inner rod; a plurality of receivers are provided inside the outer cylinder, and the receivers are located inside the side of the outer cylinder where the detection device is installed; the first signal generator faces the feed end of the arc-shaped channel, and when the receiver receives the signal from the first signal generator, the working end of the second linear driver extends; the second signal generator faces the discharge end of the arc-shaped channel, and when the receiver receives the signal from the second signal generator, the working end of the second linear driver shortens.

[0016] The advantages of this invention compared to the prior art are:

[0017] Firstly, the synchronous rotating seat in this invention drives the detection device and the pump body to move along the arc-shaped channel, which enables continuous feeding of the pump body, reduces the need to start and stop the feeding device for feeding the pump body, and allows the pump body to complete the detection during the movement, without having to stop the pump body to wait when the previous pump body is being detected, which greatly improves the continuity of the detection process.

[0018] Secondly, when the detection device in this invention detects that the pump body is unqualified, it can send a signal to start the lane-changing unit. The lane-changing unit changes the movement channel of the pump body, so that the fixed seat of the detection device drives the upper seal, the lower seal and the unqualified pump body to move from the arc-shaped channel to the waste channel, thereby removing the unqualified pump body from the arc-shaped channel. It can also classify pump bodies with different functional problems, which facilitates subsequent processing.

[0019] Thirdly, the present invention ensures that the detection devices installed on different synchronous rotating seats will not collide directly when they are in overlapping positions by cooperating with the receiver, the first signal generator and the second signal generator set on the synchronous rotating seat, thus protecting the normal operation of the equipment.

[0031] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figures 1 to 10 As shown:

[0033] A fully automatic continuous testing device for foam pump bodies includes a conveyor track 1, with a feeding device and a discharging device connected to both ends of the conveyor track 1. The pump body moves within the conveyor track 1. Several testing devices 2 are arranged along the extension path of the conveyor track 1. The conveyor track 1 includes two horizontally extending straight channels 11 on the same straight line. Several semi-circular arc-shaped channels 12 are arranged between the straight channels 11, and the arc-shaped channels 12 are connected end to end in an "S" shape. A synchronous rotating seat 3 is arranged at the axial position of each arc-shaped channel 12. Each synchronous rotating seat 3... Several identical detection devices 2 are distributed at equal angles around the perimeter. The synchronous rotating seat 3 drives the detection devices 2 to rotate around the axis of the arc-shaped channel 12. The detection device 2 includes an upper sealing element 21 for sealing the upper end of the pump body and a lower sealing element 22 for sealing the lower end of the pump body. The upper sealing element 21 and the lower sealing element 22 are coaxially mounted on the working end of the first linear drive 23. The first linear drive 23 drives the upper sealing element 21 and the lower sealing element 22 to clamp the pump body and move along the conveying track 1 following the rotation of the detection device 2. The detection device 2 completes the detection during the movement of the pump body.

[0034] The continuous testing equipment described in this application has a feeding device and a discharging device connected to both ends of the conveying track 1. The feeding device can be a vibrating feeding plate, etc., and the discharging device can be a conveyor belt or a robotic arm, etc., all of which are existing technologies and are not shown in the figure. The feeding device places the pump body to be tested on the straight channel 11 of the conveying track 1 and conveys it along the straight channel 11 to one end of the arc-shaped channel 12. In this embodiment, both the straight channel 11 and the arc-shaped channel 12 are channels for limiting the movement of the pump body. The pump body moves within the limited space of the straight channel 11 and the arc-shaped channel 12. The arc-shaped channel 12 is semi-circular. When the pump body reaches the connection point between the arc-shaped channel 12 and the straight channel 11, it stops moving. The synchronous rotating seat 3 drives one of the detection devices 2 to the axial position of the pump body. The upper seal 21, located above the pump body, moves downwards under the drive of the first linear actuator 23, and the lower seal 22, located below the pump body, moves upwards under the drive of the first linear actuator 23. The upper seal 21 and lower seal 22 clamp and seal the upper and lower ends of the pump body, allowing the pump body to move along the arc-shaped channel 12 following the movement of the detection device 2. The pump body completes the detection process during its movement. In this embodiment, the testing device 2 can be any device required for testing the pump body's liquid loading performance, pressure, and vacuum negative pressure. Each synchronous rotary seat 3 is equipped with a functional testing device. The first linear actuator 23 can be a linear cylinder or an electric push rod, etc. When the pump body passes through the first arc-shaped channel 12, the first functional test is completed. When the pump body moves to the other end of the arc-shaped channel 12, the upper seal 21 and lower seal 22 of the original testing device 2 move away from the pump body under the drive of the first linear actuator 23, releasing the clamping of the pump body. The synchronous rotary seat 3 located at the next station then drives the device to perform the following tests: Another functional testing device 2 moves to this location, clamps the pump body, and drives the pump body along the next arc-shaped channel 12 to complete a new test. This process is repeated until the pump body is conveyed to the straight channel 11 at the discharge end of the conveying track 1 for unloading. In this embodiment, the synchronous movement of the synchronous rotating seat 3, driving the testing device 2 and the pump body along the arc-shaped channel 12, allows for continuous pump feeding, reducing the need to start and stop the feeding device. The pump body can complete the test during its movement, eliminating the need to stop the pump body during the previous test, thus greatly improving the continuity of the testing process. This embodiment shows three arc-shaped channels 12, and four testing devices 2 are installed on each synchronous rotating seat 3. Operators can adjust the number of arc-shaped channels 12, synchronous rotating seats 3, and testing devices 2 on each synchronous rotating seat 3 according to actual testing needs and cost considerations to achieve the appropriate testing effect.

[0035] In order for the detection device 2 to detect the pump body when the upper seal 21 and the lower seal 22 can seal the upper and lower ends of the pump body, the following features are specifically provided:

[0036] Both the upper seal 21 and the lower seal 22 have an inner cavity and an opening 211 facing one end of the pump body. A rubber sleeve 212 is provided inside the opening 211, and the rubber sleeve 212 contacts the outer wall of the pump body to seal the pump body. At least one side air passage 213 is provided on the upper seal 21 and the lower seal 22, which extends radially along the axis of the upper seal 21 and the lower seal 22. The side air passage 213 is connected to the detection device 2 through a flexible pipe 214.

[0037] In this embodiment, both the upper seal 21 and the lower seal 22 are provided with cavities. When the first linear actuator 23 drives the upper seal 21 and the lower seal 22 to move closer to the pump body along the axial direction of the pump body, the upper and lower ends of the pump body are respectively inserted into the openings 211 of the upper seal 21 and the lower seal 22, and come into contact with the rubber sleeve 212 inside the openings 211. The rubber sleeve 212 deforms and fits against the opening of the pump body to form a seal. Figure 8 As shown, when one end of the pump body is tapered, a sealing effect can be achieved as long as the inner diameters of the opening 211 and the rubber sleeve 212 remain unchanged; for example... Figure 9 As shown, when one end of the pump body is cylindrical, the rubber sleeve 212 and the inner diameter of the rubber sleeve 212 can be set to gradually increase along the axis of the opening 211, which can also ensure the sealing effect. The setting is based on the actual product being tested. Both the upper seal 21 and the lower seal 22 are provided with side air passages 213. The side air passages 213 are connected to the testing device 2 through the pipe 214. The testing device 2 can perform operations such as vacuuming or gas delivery inside the pump body through the side air passages 213, thereby realizing the testing function of the testing device 2.

[0038] To enable the classification of pumps that fail inspection, the following features are specifically designed:

[0039] Two first linear actuators 23 for mounting the upper seal 21 and the lower seal 22 on the same axis are fixedly mounted at the upper and lower ends of the fixed base 24, which extends vertically and the working ends of the two first linear actuators 23 are arranged opposite to each other. The fixed base 24 is slidably mounted on the synchronous rotating base 3 and moves radially along the axis of the synchronous rotating base 3.

[0040] A scrap channel 13 is provided on the arc-shaped channel 12. The scrap channel 13 is located on the side of the arc-shaped channel 12 away from the feeding end of the conveying track 1, and extends inward to the arc-shaped channel 12. A lane-changing unit 14 is provided at the connection between the arc-shaped channel 12 and the scrap channel 13. The lane-changing unit 14 changes the movement path of the pump body so that the detection device 2 drives the pump body that fails the detection to convey the scrap channel 13.

[0041] In this embodiment, two first linear actuators 23 for mounting the upper seal 21 and lower seal 22 on the same axis are fixedly mounted at the upper and lower ends of the fixed base 24, respectively. The fixed base 24 can drive the upper seal 21 and lower seal 22 to move radially along the axis of the synchronous rotating base 3. Under normal conditions, the position of the fixed base 24 makes the upper seal 21 and lower seal 22 and the pump body located on the arc channel 12 on the same axis. The arc channel 12 is located at the discharge end, that is, a waste channel 13 is set at the end near the next arc channel 12. When the detection device 2 detects that the pump body is unqualified, it can send a signal to the controller. The controller starts the lane changing unit 14. The lane changing unit 14 changes the movement channel of the pump body, so that the fixed base 24 of the detection device 2 drives the upper seal 21, lower seal 22 and unqualified pump body to move from the arc channel 12 to the waste channel 13, thereby removing the unqualified pump body from the arc channel 12. It can also classify pump bodies with different functional problems for convenient subsequent processing.

[0042] In order for the lane-changing unit 14 to realize the track-changing operation of the pump body moving from the arc-shaped channel 12 to the waste channel 13, the following features are specifically set:

[0043] The lane-changing unit 14 includes a stop block 141, which is inserted into one side of the connection between the arc-shaped channel 12 and the scrap channel 13. The rotation axis of the stop block 141 is vertically arranged, and the inner side of the stop block 141 has a guide surface 142 that can be tangent to the arc-shaped channel 12 and the scrap channel 13. The stop block 141 is connected to the working end of the rotary driver 143, which is fixedly installed on one side of the arc-shaped channel 12.

[0044] In this embodiment, the lane-changing unit 14 consists of a stop block 141 and a rotary driver 143. One end of the stop block 141 is inserted into one side of the connection between the arc-shaped channel 12 and the scrap channel 13. The rotary driver 143 drives the stop block 141 to rotate around its axis. Figure 4 As shown, under normal operating conditions, the stop 141 is located on one side of the arc-shaped channel 12 and does not obstruct the movement of the pump body; Figure 3 As shown, when the detection device 2 detects that the pump body is a defective product, the detection device 2 sends a signal to the controller. The controller starts the rotary driver 143 to rotate the rotary driver 143 by a certain angle, so that the guide surface 142 is tangent to the arc-shaped channel 12 and the waste channel 13. When the synchronous rotating seat 3 rotates, it drives the detection device 2 and the pump body to the stop 141. The pump body moves along the stop 141 from the arc-shaped channel 12 to the waste channel 13. At this time, the fixed seat 24 moves radially along the axis of the synchronous rotating seat 3, changing the position of the upper seal 21 and the lower seal 22, so that the pump body can enter the waste channel 13.

[0045] In order to enable the synchronous rotating seat 3 to drive the detection device 2 to rotate, the following features are specifically designed:

[0046] The synchronous rotating seat 3 includes an inner hollow outer cylinder 31, the axis of which is on the same straight line as the axis of the arc-shaped channel 12; the outer cylinder 31 is connected to a rotary drive unit 32, which is fixedly mounted on the base 33.

[0047] In this embodiment, the synchronous rotating seat 3 has an outer cylinder 31 and a rotary drive unit 32 for driving the outer cylinder 31 to rotate. In this embodiment, the outer cylinder 31 is a hollow cube with four mounting surfaces. The operator can set the shape of the outer cylinder 31 according to the number of detection devices 2 on a single synchronous rotating seat 3 to facilitate the installation of the fixing seat 24. The rotary drive unit 32 for driving the outer cylinder 31 to rotate can be an indexing rotary disk, or it can achieve synchronous rotation of each outer cylinder 31 through gears and transmission. The servo motor ensures that the outer cylinder 31 can rotate continuously and the angle of a single rotation is 360 divided by the number of detection devices 2, ensuring that each detection device 2 can accurately position the two ends of the arc channel 12, and also providing the time for the first linear driver 23 to drive the upper seal 21 and lower seal 22 to clamp or release the pump body.

[0048] In order to control the radial movement of the fixed seat 24 along the axis of the synchronous rotating seat 3, the following features are specifically provided:

[0049] A guide plate 241 extending horizontally in the radial direction of the outer cylinder 31 is provided on the side of the fixed base 24 facing the outer cylinder 31. The guide plate 241 is inserted into the guide sleeve 311 provided around the outer cylinder 31. The guide sleeve 311 has the same cross-section as the guide plate 241. A second linear actuator 312 is fixedly installed on one side of the guide sleeve 311. The working end of the second linear actuator 312 is set facing the fixed base 24. The working end of the second linear actuator 312 moves along the length direction of the guide sleeve 311. The detection device 2 is connected to the second linear actuator 312 through a controller signal.

[0050] A limiting rod 242 protruding from the surface of the guide plate 241 is provided on one side of the guide plate 241. The limiting rod 242 is inserted into the waist-shaped hole 313 provided on the guide sleeve 311. The waist-shaped hole 313 extends along the length direction of the guide sleeve 311. When the limiting rod 242 is located at the farthest end of the waist-shaped hole 313, the upper seal 21 and the lower seal 22 are on the same straight line as the pump body on the arc-shaped channel 12.

[0051] In this embodiment, the fixed seat 24 is inserted into the guide sleeve 311 provided around the outer cylinder 31 by at least two horizontal guide plates 241 to ensure the smooth horizontal movement of the lower seal 22. A second linear actuator 312 that pushes the fixed seat 24 outward is fixedly installed on one side of the guide sleeve 311. The second linear actuator 312 can be a linear cylinder or an electric push rod, etc. The working end of the second linear actuator 312 is not connected to the fixed seat 24. Under normal working conditions, the working end of the second linear actuator 312 extends and pushes the fixed seat 24 outward. The limiting rod 242 on one side of the guide plate 241 moves into the oblong hole 313 of the guide sleeve 311. When the second linear actuator 312 pushes the fixed seat 24... When the limiting rod 242 is at the farthest end of the waist-shaped hole 313, the upper seal 21 and the lower seal 22 are on the same straight line as the pump body on the arc-shaped channel 12, and the limiting rod 242 accurately positions the fixed seat 24. When the detection device 2 detects that the pump body is a defective product, the detection device 2 sends a signal to the controller, and the controller controls the working end of the second linear actuator 312 to retract, so that when the pump body moves to the stop 141 of the lane-changing unit 14, it can conform to the guide surface 142 of the stop 141 and move from the arc-shaped channel 12 to the scrap channel 13. The fixed seat 24 loses the support of the working end of the second linear actuator 312, so that the fixed seat 24 can retract into the guide sleeve 311 following the movement of the pump body.

[0052] To prevent collisions between the upper seal 21 and lower seal 22 of the detection device 2 on the two synchronous rotating seats 3 when the pump body is qualified, as they move along the arc-shaped channel 12 to the connection point of the arc-shaped channel 12, the following features are specifically designed:

[0053] The base 33 of the synchronous rotating seat 3 is provided with an inner rod 34 extending vertically upward along the axis of the outer cylinder 31. The outer cylinder 31 is sleeved on the inner rod 34. A first signal generator 341 and a second signal generator 342 are respectively provided on the top of the inner rod 34. A plurality of receivers 314 are provided inside the outer cylinder 31. The receivers 314 are located inside the outer cylinder 31 on the side where the detection device 2 is installed. The first signal generator 341 faces the feed end of the arc-shaped channel 12. When the receiver 314 receives the signal from the first signal generator 341, the working end of the second linear driver 312 extends. The second signal generator 342 faces the discharge end of the arc-shaped channel 12. When the receiver 314 receives the signal from the second signal generator 342, the working end of the second linear driver 312 shortens.

[0054] In this embodiment, the base 33 of the synchronous rotating seat 3 is provided with an inner rod 34. The outer cylinder 31 is sleeved on the rotary drive unit 32 so that the inner rod 34 remains fixed when the outer cylinder 31 rotates. The first signal generator 341 and the second signal generator 342 are mounted on the inner rod 34, facing the feed end and the discharge end of the arc-shaped channel 12, respectively. A receiver 314 is provided inside the side of the outer cylinder 31 where the detection device 2 is installed. The first signal generator 341, the second signal generator 342 and the receiver 314 can be a through-beam laser sensor, etc. The receiver 314 moves to be on the same straight line as the first signal generator 341 and the second signal generator 342 to send a signal. When the synchronous rotating seat 3... When the detection device 2 and the pump body rotate to the discharge end of the arc-shaped channel 12, the first linear actuator 23 starts, causing the upper seal 21 and lower seal 22 to release the pump body. At this time, the receiver 314 corresponding to the detection device 2 aligns with the second signal generator 342 on the inner rod 34. After receiving the signal, the receiver 314 shortens the working end of the second linear actuator 312 through the controller. If the detection device 2 has already shortened the second linear actuator 312 due to the pump body's failure, the working end of the second linear actuator 312 remains unchanged. At this time, the fixed seat 24 on the synchronous rotating seat 3 at the next arc-shaped channel 12 also moves to that location, and the receiver 314 corresponding to the fixed seat 24 faces the inner rod 34. The first signal generator 341 operates at its working end. After receiving the signal from the first signal generator 341, the receiver 314 extends the working end of the second linear actuator 312 via a controller. The extension of the second linear actuator 312 pushes the fixed seat 24 forward until the upper seal 21 and lower seal 22 are aligned with the pump body on the same axis. During the forward movement of the fixed seat 24, it pushes the detection device 2 on the other side to move along the guide plate 241 into the guide sleeve 311. The fixed seat 24, located in front, loses the support of the working end of the second linear actuator 312, thus releasing the axial position of the pump body. Subsequently, when the synchronous rotating seat 3 rotates, it drives the fixed seat 24, which is in a retracted state, to rotate until the receiver 314 is aligned with the first signal generator 341. When the generator 341 is aligned, the receiver 314 receives the signal from the first signal generator 341 and then extends the working end of the second linear driver 312 through the controller. The extension of the second linear driver 312 pushes the fixed seat 24 of the detection device 2 located at the first arc-shaped channel 12 forward until the upper seal 21 and the lower seal 22 are on the same axis as the pump body. The detection device 2 clamps the next pump body. In this embodiment, the cooperation of the receiver 314, the first signal generator 341 and the second signal generator 342 ensures that the upper seal 21 and the lower seal 22 on the fixed seat 24 in the overlapping position will not collide directly, thus protecting the normal operation of the equipment.

[0055] Working principle: The feeding device places the pump body to be tested on the straight channel 11 of the conveying track 1, and conveys it along the straight channel 11 to one end of the arc-shaped channel 12. The synchronous rotating seat 3 drives one of the testing devices 2 to move to the axial position of the pump body. The upper seal 21 and the lower seal 22 clamp and fix the upper and lower ends of the pump body while sealing it, so that the pump body can move along the arc-shaped channel 12 with the movement of the testing device 2. The pump body completes the testing process during the movement. When the testing device 2 detects that the pump body is a defective product, it activates the lane-changing unit 14, and the pump body moves from the arc-shaped channel 12 to the scrap section. In channel 13, when the pump body passes through the first arc-shaped channel 12, the first functional test is completed. When the pump body moves to the other end of the arc-shaped channel 12, the upper seal 21 and lower seal 22 of the original detection device 2 move away from the pump body under the drive of the first linear driver 23, releasing the clamping of the pump body. The synchronous rotating seat 3 located at the next station drives the detection device 2 with another functional test to move to this place, clamps the pump body and drives the pump body to move along the next arc-shaped channel 12 and complete the new test. After repeating the above steps, the pump body is conveyed to the straight channel 11 at the discharge end of the conveying track 1 for unloading.
