Description

Technical Field

[0001] This application relates to the field of pump core testing, and more particularly to a pump core testing device. Background Technology

[0002] In the cosmetic packaging industry, pump cartridges are core components that ensure accurate product dispensing and long-term stable storage, making their performance and reliability crucial. Among these, the pump cartridge's dispensing volume per cycle and overall airtightness are two of the most critical testing indicators, directly impacting the user experience and quality assurance of the product.

[0003] Currently, the testing of these two indicators for pump cores in industrial production generally suffers from fragmented testing processes and low levels of integration. Specifically, discharge volume testing and airtightness testing need to be performed on two separate sets of testing equipment. After completing one test, the pump core must be manually transferred to another workstation before subsequent tests can be conducted. This segmented testing mode not only leads to frequent transfers of workpieces between processes but also artificially prolongs the complete testing cycle of a single pump core. Furthermore, existing testing equipment often lacks automation, requiring repeated operator intervention in multiple stages, from loading and positioning to unloading. This highly manual operation method not only increases labor intensity but also severely restricts the improvement of overall testing efficiency due to the uncertainty of human operation rhythm, making it difficult to meet the high-efficiency and rhythmic quality control requirements of modern large-scale production.

[0025] This application provides a pump core testing device with a first orientation, and the testing device includes a rotating base 100, an inflation component 200, an exhaust component 300, and a liquid bottle 400.

[0026] Specifically, the rotating base 100 has multiple feeding slots 121 on its circumferential surface for accommodating pump cores a. Each feeding slot 121 has a feeding station and a discharging station. The rotating base 100 is connected to a rotary drive unit 101 that drives its rotation. An inflation member 200 is slidably disposed on the circumferential surface of the rotating base 100 and corresponds to the feeding slots 121, and can slide along a first direction. A track ring 201 is provided on one side of the inflation member 200 along the first direction. The inflation member 200 abuts against the track ring 201. When the rotating base 100 rotates, the inflation member 200 moves along the first direction under the guidance of the track ring 201, and the inflation member 200 inflates. The inflation channel is connected to an inflation valve. An exhaust component 300 is correspondingly disposed on the side of the inflation component 200 away from the track ring 201. The exhaust component 300 is connected to a linear drive component 301, which is used to drive the exhaust component 300 to move toward or away from the inflation component 200 in a first direction. The exhaust component 300 has an exhaust channel, which is connected to a pressure sensor 302 and a first exhaust valve 303. A liquid bottle 400 is connected to the exhaust channel and has an air outlet. A detector 401 is disposed on one side of the liquid bottle 400, and the air outlet of the liquid bottle 400 is connected to a second exhaust valve 402.

[0027] See Figure 1As shown in the figure, in this embodiment, the first direction Z mentioned above is the vertical direction.

[0028] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 8 As shown, the inflation component 200 is lifted upwards and the linear drive component 301 drives the exhaust component 300 downwards, causing them to come into contact. During this process, the first exhaust valve 303 is first closed. The inflation component 200 lifts the pump core in the feeding trough 121 to the exhaust component 300. Specifically, the air inlet end of the pump core is connected to the inflation channel, and the air outlet end of the pump core is sealed to the exhaust channel to prevent gas inside the pump core from escaping from the connection between the pump core and the inflation channel and the connection between the pump core and the exhaust channel. At this time, the exhaust channel is independent of the outside. During the pressing process, the pump core... The air in the intake channel is pumped to the exhaust channel, which is connected to the air pressure sensor 302. As the linear drive 301 drives the exhaust component 300 to continue moving downward, the exhaust component 300 comes into contact with the inflation component 200. At this time, the maximum value detected by the air pressure sensor 302 can be observed, which is the pump core's output (which can be understood as the water output). The detected air pressure value information is transmitted to the processor and compared with the preset value to determine whether the pump core's output is qualified, thus realizing the detection of the pump core's output.

[0029] Please continue reading. Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown, after testing the pump core's discharge volume, it is necessary to test the airtightness of the assembly of each component of the pump core to check for leaks. Specifically, after testing the discharge volume, the exhaust component 300 and the inflation component 200 abut against each other, thereby sealing the pump core within the sealed space formed by the inflation component 200 and the exhaust component 300. Then, liquid can be poured into the liquid bottle 400 and connected to the exhaust component 300. If the pump core leaks, gas will enter the liquid bottle 400 and generate bubbles. The detector 401 detects the number of bubbles and judges the degree of leakage by the amount of bubbles generated. If the number of bubbles is greater than the preset number, the pump core is judged to be defective; if the number of bubbles is less than or equal to the preset number, it is judged to be qualified.

[0030] Specifically, when testing the airtightness of the pump core, the first exhaust valve 303 and the second exhaust valve 402 need to be closed first. Closing the first exhaust valve 303 prevents gas leakage. Next, the inflation valve is opened, and the gas from the external gas supply source is delivered to the inlet of the pump core through the inflation channel. At this time, the inflation channel is in a high-pressure gaseous state. If the pump core leaks due to gaps caused by assembly, the gas will flow from the gaps in the pump core into the sealed space. The gas will enter the liquid bottle 400 through the exhaust channel, thereby generating bubbles. During the bubble generation process, the number of bubbles is detected by the detector 401, thereby realizing the airtightness test.

[0031] Understandably, after testing the pump core's output and airtightness, the inflation valve is closed to stop inflation into the inflation channel. Then, the first exhaust valve 303 and the second exhaust valve 402 can be opened to release the gas in the exhaust channel. When the pump core needs to be unloaded, when the pump core is rotated to the unloading position, the linear drive 301 drives the exhaust component 300 back to its initial position, and under the trajectory guidance of the track ring 201, the inflation component 200 will also return to its initial position and drive the pump core to move to the loading trough 121 again. At this time, the inflation component 200 and the exhaust component 300 separate. When unloading, the inflation valve can be opened to blow air into the pump core located in the loading trough 121, so that the pump core is detached from the loading trough 121 to achieve unloading.

[0032] In this embodiment, the discharge volume detection, air tightness detection, and loading / unloading are all completed during the rotation of the rotary seat 100. Furthermore, the discharge volume detection and air tightness detection are both completed on the same equipment, eliminating the need to transfer the pump core back and forth between different equipment, thereby greatly improving the detection efficiency.

[0033] For example, the inflation valve, the first exhaust valve 303, and the second exhaust valve 402 are all solenoid valves that can be remotely controlled. Each feeding trough 121 is equipped with an inflation component 200, an exhaust component 300, a linear drive component 301, a liquid bottle 400, a first exhaust valve 303, a detector 401, and a second exhaust valve 402. That is to say, each station is equipped with a set of components for detecting the discharge volume and airtightness. In this embodiment, the detector 401 can be a fiber optic sensor or other sensors that can detect the generation of bubbles. The specific model is not limited here.

[0034] For example, the linear drive 301 is a device and component for linear drive, such as a linear cylinder or a motor screw module.

[0035] Please see Figure 2 and Figure 3As shown, in this embodiment, the rotary drive 101 is a motor, and the output end of the motor can be equipped with a corresponding reducer to reduce rotation and increase torque, thereby driving the rotary seat 100 to rotate. Specifically, the track ring 201 is a circular ring, and the top surface of the ring is provided with a corresponding groove or protrusion. The groove or protrusion abuts against the bottom of the inflatable component 200, so that as the rotary seat 100 drives the inflatable component 200 to rotate, the inflatable component 200 moves up and down under the action of the groove or protrusion and gravity.

[0036] In some embodiments, the rotating base 100 includes a base 110 and a feeding plate 120. The base 110 is connected to the rotating drive 101. A plurality of inflatable components 200 are slidably disposed on the periphery of the base 110 along a first direction. A guide plate 111 is fixedly disposed on the periphery of the base 110. A plurality of first guide holes 1111 corresponding to the inflatable components 200 are opened on the edge of the guide plate 111. The feeding plate 120 is fixedly connected to the guide plate 111. The feeding groove 121 is evenly disposed on the periphery of the feeding plate 120.

[0037] Please see Figure 4 As shown, the base 110 is connected to the rotating shaft driven by the rotating drive member 101, thereby enabling the rotating drive member 101 to drive the base 110 to rotate. Multiple inflatable members 200 are slidably arranged on the circumferential surface of the base 110 along the first direction. Specifically, the inflatable members 200 are slidably connected by a slider guide rail. In order to make the up-and-down movement of the inflatable members 200 more stable, a guide plate 111 is fixedly installed on the top surface of the base 110, and multiple evenly distributed first guide holes 1111 are opened through the edge of the guide plate 111, which correspond one-to-one with the positions of the inflatable members 200. This allows the inflatable members 200 to move and be lifted to the feeding trough 121 through the first guide holes 1111, thereby lifting the pump core.

[0038] Continue reading Figure 4 The upper surface of the guide plate 111 is connected to the feeding plate 120 through multiple columns. Then, multiple feeding slots 121 are evenly opened on the periphery of the feeding plate 120, and the position of each feeding slot 121 corresponds one-to-one with the position of each inflator 200, so that the pump core in the feeding slot 121 will move toward the exhaust component 300 during the lifting process of the inflator 200.

[0039] In some embodiments, the rotary seat 100 further includes a driven plate 130 connected to the feeding plate 120, and the driven plate 130 has a plurality of second guide holes 131 that penetrate the driven plate 130 and correspond to the feeding groove 121.

[0040] Please continue reading. Figure 4As shown, the second guide hole 131 is located directly below the exhaust component 300, so that when the linear drive component 301 drives the exhaust component 300 to descend, it can pass through the second guide hole 131 and guide the exhaust component 300 through the second guide hole 131, thereby making the exhaust component 300 more stable during the lifting and lowering movement.

[0041] In some embodiments, the inflatable member 200 includes a first rod 210, an inflation hole 211 is provided in the first rod 210 along a first direction, and an installation groove 212 is provided at the end of the first rod 210 facing the exhaust member 300. The inflation hole 211 communicates with the installation groove 212. A roller 220 is rotatably provided at the end of the first rod 210 away from the exhaust member 300, and the roller 220 abuts against the track ring 201.

[0042] See Figure 5 and Figure 6 As shown, an air inlet 211 is opened in the axial direction inside the first rod 210 to guide and transport the gas, and an installation groove 212 is opened on the top of the first rod 210 to accommodate the pump core, so that the pump core can be lifted together with the first rod 210 to achieve movement.

[0043] If the bottom of the first rod 210 directly contacts the upper surface of the track ring 201, sliding friction will occur between the first rod 210 and the track ring 201 as the first rod 210 rotates. Without lubrication, the contact surfaces of the track ring 201 and the first rod 210 will wear, resulting in the inflation component 200 failing to meet the required lifting or lowering accuracy. However, using lubricating fluid or grease may pollute the working environment. Therefore, in this embodiment, a roller 220 is rotatably installed at the bottom of the first rod 210. By having the circumferential surface of the roller 220 contact the upper surface of the first rod 210, sliding friction is converted into rolling friction, thereby reducing component wear caused by friction.

[0044] In some embodiments, an inflation seat 230, a support seat 240, and a receiving seat 250 are sequentially arranged in the mounting groove 212 along a first direction. An inflation nozzle 231 is provided on the end face of the inflation seat 230 facing the support seat 240. An air passage 232 is provided in the inflation seat 230 through the air nozzle 231 and the air passage 232 is connected to the inflation hole 211. An clearance hole 241 is provided in the support seat 240 through the support seat 240. The air nozzle 231 is at least partially disposed in the air passage 232. An receiving groove 251 for accommodating the pump core is provided in the receiving seat 250, and the clearance hole 241 is connected to the receiving groove 251.

[0045] See Figure 6 and Figure 7 as well as Figure 11As shown, when testing the pump core's output and airtightness, it is necessary to seal the connection between the pump core's air inlet and the inflation channel to prevent gas leakage at the connection. To this end, an inflation seat 230, a support seat 240, and a receiving seat 250 are arranged in the receiving groove 251 and they abut against each other in sequence. The pump core is placed in the receiving groove 251, and the pump core's inlet passes through the clearance hole 241 and cooperates with the inflation nozzle 231 to form a seal. Gas enters the pump core through the airflow channel formed by the inflation hole 211 and the air passage hole 232.

[0046] Specifically, the exhaust component 300 provides a downward pressure to the pump core, the air inlet of the pump core is tightly sealed against the circumference of the air inlet 231, and the bottom of the pump core abuts against the upper surface of the support seat 240, further achieving a seal.

[0047] In this embodiment, the inflatable base 230 and the inner wall of the mounting groove 212 are sealed together, as are the receiving base 250 and the inner wall of the mounting groove 212.

[0048] In this embodiment, the opening of the receiving groove 251 has a beveled guide surface, which makes it easier for the pump core to enter the receiving groove 251.

[0049] In some embodiments, the exhaust channel includes a first air passage and a second air passage. The exhaust component 300 includes a second rod 310, which has a first exhaust hole 311 along a first direction and a second exhaust hole 312 connected to the first exhaust hole 311 along its radial direction. The second exhaust hole 312 is connected to the air pressure sensor 302. The exhaust component 300 also includes a sealing seat 320, which has an exhaust groove 321 along the first direction. The exhaust groove 321 is connected to the first exhaust hole 311 to form a first air passage. The sealing seat 320 is also provided with a third exhaust hole 322 for communicating between the exhaust groove 321 and the outside. The third exhaust hole 322 is connected to the exhaust groove 321 to form a second air passage. The third exhaust hole 322 is connected to the first exhaust valve 303.

[0050] Please see Figure 8 as well as Figure 9 as well as Figure 11 As shown, when the exhaust component 300 is driven down by the second rod 310 and comes into contact with the inflation component 200, the exhaust groove 321 connects with the receiving groove 251 to form a sealed space for accommodating the pump core. The air outlet of the pump core is connected to the exhaust nozzle at the end of the second rod 310. The exhaust nozzle is conical, which can seal the exhaust nozzle with the air outlet of the pump core to prevent air leakage at the connection. The exhaust groove 321 is connected to the liquid bottle 400 through the third exhaust hole 322. It can be understood that the air inlet and outlet of the pump core are sealed to prevent gas from leaking out from the air inlet and outlet and affecting the detection effect.

[0051] Understandably, when the discharge volume test is performed, the gas enters the first exhaust port 311 through the exhaust nozzle. That is, the gas is transmitted to the position of the pressure sensor 302 through the first air passage formed by the exhaust groove 321 and the first exhaust port 311, so as to realize the pressure detection in the first exhaust port 311. If the air tightness test is required, if the pump core leaks, the gas will enter the exhaust groove 321 and finally be discharged into the liquid bottle 400 through the third exhaust port 322, thereby forming bubbles in the liquid bottle 400 to realize the air tightness test.

[0052] In some embodiments, the exhaust groove 321 includes a first slot 3211 and a second slot 3212 arranged sequentially along a first direction toward the second rod 310. The first slot 3211 communicates with the second slot 3212, and the second slot 3212 is connected to the first exhaust hole 311. The sealing seat 320 is also provided with a first connecting hole 3221 and a second connecting hole 3222. The third exhaust hole 322 is connected to the first slot 3211 through the first connecting hole 3221, and the third exhaust hole 322 is connected to the second slot 3212 through the second connecting hole 3222.

[0053] Please continue reading. Figure 9 As shown, since the pump core may leak air at both its bottom and top positions, in order to ensure that the pump core can be detected at both the first slot 3211 and the second slot 3212, a first connecting hole 3221 and a second connecting hole 3222, both connected to the third exhaust hole 322, are provided in the sealing seat 320. The first connecting hole 3221 transports the gas leaking from the pump core into the first slot 3211 to the third exhaust hole 322, and the second connecting hole 3222 transports the gas leaking from the leaking pump core into the second slot 3212 to the third exhaust hole 322. Finally, the gas is transported to the liquid bottle 400 through the third exhaust hole 322. In this embodiment, the third exhaust hole 322 and the liquid bottle 400 are connected by a gas pipe.

[0054] In some embodiments, the liquid bottle 400 includes a bottle body 410, the bottle body 410 having a cavity 411, a bottom cover 420 provided at one end of the bottle body 410, a top cover 430 provided at the end of the bottle body 410 away from the bottom cover 420, a detector 401 extending through the top cover 430 into the cavity 411, and the top cover 430 also having a fourth vent hole 431 connected to the cavity 411, the fourth vent hole 431 being connected to the second vent valve 402.

[0055] Please see Figure 10As shown, the entire liquid bottle 400 consists of a bottle body 410, a bottom cap 420, and a top cap 430. The bottle body 410 is provided with an air inlet that communicates with the cavity 411. The air inlet can be connected to the third exhaust port 322 through an air pipe, so that the gas from the third exhaust port 322 can be delivered into the cavity 411 to form bubbles that are detected by the detector 401.

[0056] In this embodiment, after the airtightness test of the pump core is performed, the pressure inside needs to be released. For this purpose, the pressure can be released by opening a fully penetrating fourth vent 431 on the top cover 430. Specifically, the fourth vent 431 is connected to the second vent valve 402 through an air pipe, and then the pressure relief and exhaust are controlled by the second vent valve 402.

[0057] In some embodiments, the loading station is provided with a feeder 122, and the unloading station includes a qualified product unloading station and a defective product unloading station. The qualified product unloading station is provided with a first feeder 123, and the defective product unloading station is provided with a second feeder 124.

[0058] See Figure 1 and Figure 2 As shown, in this embodiment, the feeder 122 is a linear vibrating feeder. Specifically, the pump core is conveyed to the linear vibrating feeder in an orderly manner by the vibrating plate, and then the pump core is conveyed to each rotating feeding trough 121 by the linear vibrating feeder, thereby sequentially detecting the discharge volume and airtightness of the pump core.

[0059] In this embodiment, both the first feeder 123 and the second feeder 124 are feeding guides, i.e., guides with grooves. Specifically, when feeding is required, for example, when feeding qualified products, at the qualified product feeding position, the inflation valve is opened and air is blown into the pump core through the inflation channel, causing the pump core to detach from the feeding trough 121 and fall into the first feeder 123, thus feeding the qualified product and allowing it to enter the next process. Similarly, when feeding defective products, at the defective product feeding position, the inflation valve is opened and air is blown into the pump core through the inflation channel, causing the pump core to detach from the feeding trough 121 and fall into the second feeder 124, thus feeding the defective product and allowing it to enter the next process.

[0060] In some embodiments, the pump core testing equipment further includes a frame, which includes a frame body 500 and a mounting plate 510. The mounting plate 510 is disposed on the frame body 500, and the rotating seat 100 is disposed on the mounting plate 510.

[0061] The rotary drive 101 is located below the mounting plate 510. The base 110 is rotatably mounted on the mounting plate 510. The rotary drive 101 is connected to the base 110's shaft. The rotary drive 101 drives the base 110 to rotate. In order to ensure safety, a cover adapted to it is provided on the circumference of the frame.
