[0002] The micro pump is a small pump, which can be applied to aromatherapy machines, soap machines and the like, and is widely used.

[0049] The detection device and detection method of the micropump according to the embodiments of the present application are described below with reference to the accompanying drawings.

[0050] With reference to Figure 1 and Figure 2 , the present application aims to provide an embodiment of a detection device for a micropump.

[0051] In the present embodiment, the detection device mainly comprises a feeding device 100, a material moving device 140 and a detection device 230.

[0052] The feeding device 100 can comprise a feeding robot and a feeding seat 110, and the feeding robot can place the micropumps one by one in the placement holes 120 of the feeding seat 110, or can place several micropumps at a time in several placement holes 120 to improve the placement efficiency.

[0053] In some specific embodiments of the present application, the feeding robot can be provided with a light identifier, so that when a placement hole 120 has a micro pump, the feeding robot will not place a micro pump in the placement hole 120, thereby preventing the placement of two micro pumps in one placement hole 120 and avoiding feeding confusion.

[0054] For the placement holes 120, the placement holes 120 are arranged in a row to adapt to the arrangement of the detection mechanism 240 and facilitate the clamping of the feeding device 140.

[0055] Referring to Figure 3 In the placement holes 120, the placement holes 120 are provided with elastic lifting seats 130 for supporting the micro pumps. The bottom of the elastic lifting seat 130 is provided with a spring for supporting the elastic lifting seat 130. Meanwhile, the outer contour of the elastic lifting seat 130 matches the shape of the inner surface of the placement hole 120, so that the elastic lifting seat 130 slides up and down along the placement hole 120.

[0056] In some specific embodiments of the present application, the elastic lifting seat 130 can be provided with a second elastic pad 410 for supporting the micro pump to flexibly contact the micro pump, thereby reducing friction loss and avoiding pressure injury.

[0057] In some specific embodiments of the present application, the elastic lifting seat 130 can be provided with a first detector 420 for detecting whether the micro pump is present, so as to confirm whether the elastic lifting seat 130 has placed a micro pump, thereby facilitating the control of the feeding robot and the feeding device 140.

[0058] In some specific embodiments of the present application, the side wall of the placement hole 120 can be provided with a second detector 430 for detecting the lifting of the elastic lifting seat 130. By detecting the position of the elastic lifting seat 130, the presence of the micro pump can be confirmed, and whether the lifting of the elastic lifting seat 130 is normal can also be confirmed, thereby avoiding affecting the cooperation with the blocking material 270.

[0059] Referring to Figure 2 For the feeding device 140, the feeding device 140 includes a horizontal moving frame 150, a lifting frame 160 provided on the horizontal moving frame 150, and a clamping assembly 170 provided on the lifting frame 160. The clamping assembly 170 includes a front clamping jaw 180, a rear clamping jaw 190, a clamping power member 200 for driving the front clamping jaw 180 and the rear clamping jaw 190 to approach each other to clamp a material, the front clamping jaw 180 is provided with a plurality of front clamping recesses 210, the rear clamping jaw 190 is provided with rear clamping recesses 220 corresponding to the front clamping recesses 210, and the front clamping recesses 210 and the rear clamping recesses 220 cooperate to form a clamping space for clamping a micro pump.

[0060] That is, when the placement hole 120 has a micro pump, the horizontal moving frame 150 moves horizontally so that the lifting frame 160 is in a feeding position, the lifting frame 160 is lowered, the clamping power 200 drives the front clamping jaw 180 and the rear clamping jaw 190 to approach each other, forming a clamping space, the clamping space clamps the cylindrical part of the micro pump, then the lifting frame 160 is raised, the clamping assembly 170 can take out the micro pump from the placement hole 120, then the horizontal moving frame 150 reverses the horizontal movement, and the lifting frame 160 is lowered again to place the micro pump at the detection device 230.

[0061] For the clamping power 200, the clamping power 200 can be a pneumatic cylinder, so that the front clamping jaw 180 and the rear clamping jaw 190 move quickly and reliably, and the manufacturing cost is low.

[0062] For the detection device 230, the detection device 230 includes a detection mechanism 240 and a placement translation seat 250, the placement translation seat 250 has a plurality of placement parts 260 for placing the micro pump, and the placement translation seat 250 has a first position and a second position, in the first position, the detection mechanism 240 can detect the micro pump of the placement part 260, and in the second position, the front clamping recess 210 and the rear clamping recess 220 can clamp the micro pump.

[0063] That is, the material moving device 140 places the micro pump at the placement translation seat 250, the placement translation seat 250 moves the micro pump to the detection mechanism 240, and the detection mechanism 240 performs detection work.

[0064] In some specific embodiments of the present application, the placement translation seat 250 can be driven by a pneumatic cylinder, unified power, and simplified configuration.

[0065] In some specific embodiments of the present application, the placement part 260 can be vertically through, and the inner surface of the placement part 260 matches the outer contour of the micro pump, facilitating connection and communication for detection, and avoiding misplacement.

[0066] In some specific embodiments of the present application, the detection mechanism 240 can include a downward pressing detection assembly 440 located above the placement translation seat 250, an upward pressing detection assembly 450 located below the placement translation seat 250, and a side moving detection assembly 460 located on one side of the placement translation seat 250.

[0067] That is, the detection mechanism 240 presses upward and downward and approaches laterally to facilitate connection of the electrical interface and the pipe interface of the micro pump, meet the needs of electrical communication and gas-liquid communication, so that the micro pump can operate normally, and meet the detection needs such as air tightness detection, durability detection, and output detection.

[0068] In some specific embodiments of the present application, the side shift detection assembly 460 can include a side shift seat parallel to the moving direction of the material placing translation seat 250, a left lifting detection piece and a right lifting detection piece arranged on the side shift seat, the left lifting detection piece and the right lifting detection piece are used to detect two micro pumps which are arranged in partial left-right symmetry, and the corresponding detection piece is turned on to detect when the left lifting detection piece or the right lifting detection piece is lowered.

[0069] That is, during detection, the side shift seat is close to the micro pump, and then the left lifting detection piece and the right lifting detection piece are pressed down, for example, the micro pump supports the left lifting detection piece, the pipeline of the left lifting detection piece is turned on with the left lifting detection piece, which is convenient for air or liquid communication, and meets the detection needs of at least two micro pumps.

[0070] Since the present detection equipment can detect multiple micro pumps at the same time, the detection mechanism 240 also has multiple groups.

[0071] When a certain detection mechanism 240 fails or detects inaccurately, if the micro pump is still placed in the material placing part 260, the failed detection mechanism 240 will inevitably detect, and the detection mechanism 240 will obtain an incorrect detection result and alarm, affecting the use of the detection equipment. That is, when several detection stations are invalid, if the material is still normally loaded, invalid detection exists, and re-detection needs to be performed on other detection stations.

[0072] If no loading is performed, the stress of the automatic loading and unloading mechanism is unbalanced, that is, the stress of the material clamping assembly 170 of the material shifting device 140 is unbalanced, which can cause other micro pumps to easily fall during the loading and unloading process and damage the product.

[0073] Specifically, when one side of the front claw 180 and the rear claw 190 lacks a micro pump, due to the action of the material clamping power piece 200 on the middle part of the front claw 180 and the rear claw 190, the gap on the other side of the front claw 180 and the rear claw 190 increases, the micro pump cannot be effectively clamped, the micro pump is easily damaged, and at the same time, the effective station is not loaded and cannot be detected.

[0074] To solve the above problems, the present application is improved, a material blocking piece 270 is additionally arranged between the front claw 180 and the rear claw 190, the number of the material blocking piece 270 is equal to the number of the invalid detection station, and the positions correspond, so that invalid detection can be avoided, and the micro pump can be firmly fixed to avoid falling during the loading and unloading process.

[0075] Specifically, the front clamping jaw 180 or the rear clamping jaw 190 is provided with a plurality of material blocking pieces 270, the outer contour of the material blocking piece 270 matches the material clamping space, when the material clamping assembly 170 is lowered to take the material, the material blocking piece 270 can abut against the micro pump and make the micro pump and the elastic lifting seat 130 synchronous, so that the material clamping space fails to clamp the material.

[0076] It is easy to understand that, by setting the elastic lifting seat 130 and the material blocking piece 270, when some station or some stations of the detection mechanism 240 fail, for example, poor conductivity or poor air tightness, the material blocking piece 270 can be set in the corresponding material clamping space, and when the material moving device 140 moves the material, the material blocking piece 270 will press the micro pump, so that the micro pump and the elastic lifting seat 130 are lowered together, so that the material clamping space cannot clamp the micro pump, that is, the material moving device 140 can only provide the micro pump to the effective station, avoiding invalid detection.

[0077] At the same time, since the outer contour of the material blocking piece 270 matches the material clamping space, it avoids that the material clamping space lacks support due to the lack of micro pumps, avoids uneven force on the front clamping jaw 180 and the rear clamping jaw 190, and avoids that individual micro pumps are loose and fall off.

[0078] Referring to Figure 3 In some specific embodiments of the present application, the front material clamping recess 210 can be provided with a front ring groove 280 for positioning the material blocking piece 270, the rear material clamping recess 220 is provided with a rear ring groove 290 for positioning the material blocking piece 270, the front ring groove 280 or the rear ring groove 290 is provided with a through hole 300, and the through hole 300 is provided with a locking screw 310 connected to the material blocking piece 270.

[0079] It is easy to understand that, by setting the front ring groove 280 and the rear ring groove 290, the material blocking piece 270 can be stably supported, so that the material blocking piece 270 can normally press the micro pump, and by setting the through hole 300 and the locking screw 310, the material blocking piece 270 can be fixed on the corresponding clamping jaw, avoiding that the front clamping jaw 180 and the rear clamping jaw 190 approach and move away from each other, causing the material blocking piece 270 to fall off.

[0080] Referring to Figure 4 In some specific embodiments of the present application, the material blocking piece 270 can include a front shaft for inserting the front material clamping recess 210 and a rear shaft for inserting the rear material clamping recess 220, and the material blocking piece 270 further includes a T-shaped rod 340, three ends of the T-shaped rod 340 are connected to a front half shaft 320, a rear half shaft 330 and a gland 350 respectively, and the gland 350 is used to press the micro pump.

[0081] That is, by turning the material blocking piece 270, the material blocking piece 270 has two states, when the pressure cover 350 is down, the outer contour of the pressure cover 350 matches the material clamping space, ensuring that the material clamping assembly 170 is balanced, at the same time, the pressure cover 350 can press the micro pump.

[0082] When the pressure cover 350 is up, the pressure cover 350 is above the material clamping space and does not touch the micro pump, which does not affect the normal clamping of the material clamping space.

[0083] In this embodiment, the cylindrical part of the micro pump is injection molded or cast, and has a draft angle, so that when the coincidence of the cylindrical part of the micro pump with the material clamping space is low, the material clamping space will not clamp the micro pump, so that the material blocking piece 270 is effective.

[0084] In some specific embodiments of the present application, the material blocking piece 270 can have a first elastic pad 400 abutting the micro pump, that is, the pressure cover 350 has a first elastic pad 400, which reduces the hard contact and protects the micro pump.

[0085] In some specific embodiments of the present application, the front material clamping recess 210 can be provided with a square groove part 360 accommodating the end of the front shaft, the front shaft has a square rod end 370 matching the square groove part 360, the rear material clamping recess 220 is provided with a reset spring 380, the reset spring 380 is sleeved on the rear half shaft 330, and the reset spring 380 is used to push the T-shaped rod 340, so that the square rod end 370 is inserted into the square groove part 360.

[0086] It is easy to understand that, by providing the square groove part 360, the square rod end 370 and the reset spring 380, the pressure cover 350 of the material blocking piece 270 can also be kept in a state, avoiding the material blocking piece 270 from rotating unexpectedly and failing to function normally.

[0087] In use, the material blocking piece 270 is actuated, the reset spring 380 is compressed, the square rod end 370 is separated from the square groove part 360, the material blocking piece 270 can be rotated, so that the pressure cover 350 is in the selected state, then the material blocking piece 270 is released, the reset spring 380 rebounds, the square rod end 370 is inserted into the square groove part 360, so that the material blocking piece 270 is fixed, avoiding the material blocking piece 270 from rotating unexpectedly.

[0088] In this embodiment, the distance between the front clamping jaw 180 and the rear clamping jaw 190 changes less, and the reset spring 380 enables the front shaft and the rear shaft to keep connected and matched with the front clamping jaw 180 and the rear clamping jaw 190, avoiding the material blocking piece 270 from falling off.

[0089] In some specific embodiments of the present application, the top of the front clamping jaw 180 or the top of the rear clamping jaw 190 can be provided with a sensor 390 for detecting the presence or absence of the pressing cover 350, and the sensor 390 is electrically connected to the controller of the detection device to confirm the state of the material blocking piece 270 and ensure that the material blocking piece 270 functions normally.

[0090] In some specific embodiments of the present application, the front clamping jaw 180 or the rear clamping jaw 190 can have a sliding groove to facilitate the adjustment of the position of the sensor 390.

[0091] In some specific embodiments of the present application, the detector and the sensor 390 can include a photoelectric sensor, which is accurate and low in manufacturing cost.

[0092] With reference to Figure 5 , the present application also provides a detection method of a micro pump, which is applied to the detection device of any one of the above micro pumps.

[0093] The detection method of the micro pump comprises the following steps:
