Description

Technical Field

[0001] The present application relates to the technical field of leakage testing, and in particular to a material moving device and leakage testing equipment. Background Art

[0002] In the medical industry, demand for mature pharmaceuticals is generally high, necessitating high production efficiency. For example, pharmaceutical filling, packaging, and leak testing equipment must achieve a production capacity of at least 60 pcs / min, with higher capacity requirements reaching 90 or 120 pcs / min. To achieve this high production capacity, product loading and unloading also require high efficiency.

[0003] During leak testing of plastic or glass ampoules (typically using a vacuum decompression method), a material transfer device is used to facilitate rapid loading. This device typically includes a turntable and a lever. The lever is mounted on the turntable, and as the turntable rotates, the lever pushes the ampoules to the loading position. Once the ampoules reach the loading position, the lever moves upward relative to the turntable to prevent the lever from continuing to rotate and pushing them away from the loading position. Furthermore, when the lever is needed to load the next batch of ampoules, it moves downward relative to the turntable to move the next batch.

[0004] In related art, material transfer devices use a discharge block to raise and lower the lever. The discharge block has an ascending slope, a horizontal surface, and a descending slope. The ascending slope is used to raise the lever, and the descending slope is used to lower the lever. However, the discharge block takes up a lot of space, easily interfering with the installation of other devices, and is inconvenient to use. Utility Model Content

[0055] Reference Figures 1 to 4 According to the first embodiment of the present application, the material transfer device includes a carrier 100, a first material transfer module 200, a stopper 310 (see Figure 4 ), the first guide 320 and the second guide 330. The carrier 100 is provided with a carrying surface 111, which is used to carry the product 400 (refer to Figure 2 The first material moving module 200 includes a first driving assembly 210, a first mounting seat 220 and a first pushing member 230. The first pushing member 230 is mounted on the first mounting seat 220. The first pushing member 230 can move to a first position relative to the first mounting seat 220 (refer to FIG. Figure 2 ) or the second position (refer to Figure 3When the first pusher 230 is in the first position, the minimum distance D between the first pusher 230 and the carrying surface 111 is less than the height H of the product 400. When the first pusher 230 is in the second position, the minimum distance D between the first pusher 230 and the carrying surface 111 is not less than the height H of the product 400. The first driving assembly 210 is used to drive the first mounting seat 220 to move, so that the first pusher 230 in the first position pushes the product 400 carried by the carrying surface 111.

[0056] The stopper 310 is mounted on the first mounting base 220 and is used to detachably secure the first pusher 230 in the second position. The first guide 320 is mounted on the platform 100 and is used to drive the first pusher 230 from the first position to the second position. The second guide 330 is mounted on the platform 100 and is used to drive the first pusher 230 from the second position to the first position.

[0057] The material moving device according to the embodiment of the present application has at least the following beneficial effects: when the first pushing member 230 is in the first position, the first pushing member 230 can push the product 400 (for example, an ampoule); when the first pushing member 230 is in the second position, the first pushing member 230 no longer pushes the product 400; the first guide member 320 is responsible for moving the first pushing member 230 from the first position to the second position, the limiting member 310 is responsible for keeping the first pushing member 230 in the second position, and the second guide member 330 is responsible for moving the first pushing member 230 from the second position to the first position. Therefore, the movement and holding functions of the first pushing member 230 are respectively realized by the limiting member 310, the first guide member 320 and the second guide member 330. The installation positions of the limiting member 310, the first guide 320 and the second guide 330 can be arranged as needed without having to be connected into a whole, which has higher space utilization and is more convenient to use.

[0058] Specifically, the first drive assembly 210 can drive the first pusher 230 to perform circular motion. In this case, the first drive assembly 210 can include a motor or a rotary cylinder. In another embodiment, the first drive assembly 210 can also drive the first pusher 230 to perform linear motion. In this case, the first drive assembly 210 can include one of a linear motor, a cylinder, an oil cylinder, a motor-driven rack and pinion mechanism, a motor-driven crank slider mechanism, a motor-driven synchronous wheel and belt mechanism, and a motor-driven sprocket and chain mechanism.

[0059] It should be noted that, in order to reduce the probability of the product 400 escaping from the first pusher 230 during the process of the first pusher 230 pushing the product 400, the carrier 100 is further provided with a first guide groove 150. The length direction of the first guide groove 150 is the same as the motion trajectory of the first pusher 230 driven by the first drive assembly 210. For example, if the motion trajectory of the first pusher 230 driven by the first drive assembly 210 is arc-shaped, the length direction of the first guide groove 150 is also arc-shaped; if the motion trajectory of the first pusher 230 driven by the first drive assembly 210 is straight, the length direction of the first guide groove 150 is also straight.

[0060] When the product 400 is in the first guide groove 150, the inner surface of the first guide groove 150 can limit the movement direction of the product 400, thereby reducing the probability of the product 400 escaping from the first pusher 230. The specific formation of the first guide groove 150 is described below.

[0061] It should be noted that the height H of the product 400 refers to the height of the product 400 when it is normally placed on the supporting surface 111. When the minimum distance D between the first pusher 230 and the supporting surface 111 is less than the height H of the product 400, as long as the product 400 is in the moving path of the first pusher 230, the first pusher 230 and the product 400 will overlap in the horizontal direction. Once the first pusher 230 approaches the product 400, it can push the product 400. Similarly, when the minimum distance D between the first pusher 230 and the supporting surface 111 is not less than the height H of the product 400, the first pusher 230 and the product 400 no longer overlap in the horizontal direction, the first pusher 230 is located above the product 400, and the first pusher 230 cannot push the product 400 in the horizontal direction.

[0062] In another embodiment, the first guide member 320 may also include an actuator such as a cylinder or a linear motor, which actively pushes the first pusher 230 from the first position to the second position. Similarly, the second guide member 330 may also include an actuator such as a cylinder or a linear motor, which actively pushes the first pusher 230 from the second position to the first position.

[0063] Reference Figure 3 In some embodiments of the present application, the limiting member 310 can magnetically attract the first pushing member 230 located at the second position.

[0064] The magnetic adsorption method has a simple structure, and the process of the first pusher 230 entering or leaving the second position is relatively simple, which is beneficial to simplifying the structure of the material moving device and increasing the speed at which the first pusher 230 enters or leaves the second position.

[0065] Reference Figure 3In an improved solution of the above embodiment, the limiting member 310 includes a magnet 311, and the material of the first pushing member 230 includes one of iron, cobalt and nickel.

[0066] By setting the limit member 310 as a magnet 311 and setting the first pusher 230 as a magnetic material, the first pusher 230 is not magnetic, which helps to reduce the possibility of the first pusher 230 adsorbing other components (such as the linear bearing 240), and the movement of the first pusher 230 between the first position and the second position is smoother.

[0067] Specifically, refer to Figure 4 The first material moving module 200 further includes a connecting block 280, which is located above the guide base 270. The left end of the connecting block 280 is fixed to the guide base 270 via screws. A magnet 311 is located below the connecting block 280 and is fixed to the right end of the connecting block 280 via screws or glue. The magnet 311 is located above the chute 271. When the first material pushing member 230 is in the second position, the magnet 311 can attract the first material pushing member 230.

[0068] In another embodiment, the limiting member 310 includes one of iron, cobalt and nickel, and a magnet 311 is fixed to one end of the first pushing member 230 close to the limiting member 310, so that the limiting member 310 can also magnetically attract the first pushing member 230 located in the second position.

[0069] Reference Figure 6 In some embodiments of the present application, the limiting member 310 includes an elastic member 312 , and the elastic member 312 and the first mounting seat 220 can clamp the first pushing member 230 located at the second position.

[0070] By providing the elastic member 312 , the first pushing member 230 can be detachably fixed at the second position, and it is convenient to stay at the second position or to leave the second position.

[0071] Specifically, refer to Figure 6 The first material transfer module 200 further includes a pressing head 291, and the elastic member 312 includes a compression spring. The pressing head 291 is slidably connected to the guide seat 270, and the pressing head 291 slides horizontally relative to the guide seat 270. The pressing head 291 is supported against the guide seat 270 by the compression spring. When the compression spring is compressed, the pressing head 291 tends to enter the chute 271.

[0072] The pressing head 291 is provided with a third inclined surface 292. The first pusher 230 enters the chute 271 and slides along the third inclined surface 292, thereby pushing the pressing head 291, causing the pressing head 291 to compress the compression spring. When the first pusher 230 moves to the second position, the pressing head 291 and the guide seat 270 together clamp the first pusher 230. In other words, the elastic member 312 and the first mounting seat 220 together clamp the first pusher 230 in the second position.

[0073] In another embodiment, the elastic member 312 may also be a bellows, a rubber column, etc.

[0074] Reference Figure 1 In some embodiments of the present application, the moving direction of the first pusher 230 driven by the first driving component 210 is a first direction (for example, the first direction is counterclockwise (viewed from top to bottom)), and the position of the first guide member 320 relative to the carrier 100 along the first direction is adjustable.

[0075] For products 400 of different sizes, the pushing end position of the first pusher 230 is different. By adjusting the position of the first guide 320 relative to the carrier 100 along the first direction, the pushing end position of the first pusher 230 can be adjusted, thereby making the material transfer device more compatible.

[0076] Specifically, the platform 100 may be provided with a plurality of mounting holes 121 (e.g., threaded holes or through holes) along the first direction, and the first guide member 320 may be secured to the platform 100 via fasteners (e.g., screws or bolts) passing through the mounting holes 121. To adjust the position of the first guide member 320, the fasteners are loosened, the first guide member 320 is moved to the target position, and the first guide member 320 is secured to the platform 100 again using the fasteners. This completes the position adjustment of the first guide member 320 relative to the platform 100 along the first direction.

[0077] In another embodiment, the carrier 100 may be provided with a waist-shaped hole, the length direction of the waist-shaped hole being arranged along the first direction, and the first guide member 320 is fixed to the carrier 100 by a fastener (such as a screw or bolt) passing through the waist-shaped hole, thereby also realizing the position adjustment of the first guide member 320 relative to the carrier 100 along the first direction.

[0078] Reference Figure 1 In some embodiments of the present application, the moving direction of the first pusher 230 driven by the first driving component 210 is set as the first direction, and the position of the second guide member 330 relative to the carrier 100 along the first direction is adjustable.

[0079] By adjusting the position of the second guide member 330 relative to the carrier 100 along the first direction, the pushing starting position of the first pusher 230 can be adjusted, which is conducive to reasonably arranging the position of the second guide member 330 and making the position arrangement of the second guide member 330 more flexible.

[0080] The position adjustment structure of the second guide member 330 relative to the carrier 100 along the first direction may refer to the first guide member 320 and will not be described again here.

[0081] Reference Figure 1 and Figure 5 In some embodiments of the present application, the first material moving module 200 also includes a roller 290, which is installed on the first pushing member 230, and the moving direction of the first pushing member 230 driven by the first driving component 210 is the first direction; the first guide member 320 is provided with a first inclined surface 321, and the first inclined surface 321 gradually rises along the first direction; the second guide member 330 is provided with a second inclined surface 331, and the second inclined surface 331 gradually descends along the first direction; when the first driving component 210 drives the first pushing member 230 to move along the first direction, the roller 290 can roll along the first inclined surface 321 and the second inclined surface 331.

[0082] By setting a first inclined surface 321 on the first guide member 320 and a second inclined surface 331 on the second guide member 330, the power of the first driving component 210 can not only make the first pushing member 230 move along the first direction, but also realize the switching of the first pushing member 230 between the first position and the second position. The structure of the material moving device is simpler and the equipment cost of the material moving device is lower.

[0083] The following describes a specific embodiment in which the first guide member 320 drives the first pusher 230 to move from the first position to the second position, and describes a specific embodiment in which the second guide member 330 drives the first pusher 230 to move from the second position to the first position.

[0084] Reference Figure 4 , the first pusher 230 can move in the up and down direction relative to the first mounting seat 220, and the first position is located below the second position. At this time, the first material moving module 200 also includes a slider 250, a nut 260, a linear bearing 240 and a guide seat 270. The guide seat 270 is located above the first mounting seat 220, and the guide seat 270 is fixed to the first mounting seat 220 by fasteners. The guide seat 270 is provided with a slide groove 271, and the length direction of the slide groove 271 is arranged along the up and down direction. The first mounting seat 220 is provided with a first through hole 221, and the linear bearing 240 is passed through the first through hole 221, and the linear bearing 240 is fixed to the mounting seat 220 by a set screw. The first pusher 230 is inserted into the linear bearing 240, so that the first pusher 230 can move in the up and down direction relative to the first mounting seat 220.

[0085] The slider 250 is positioned within the chute 271, and the upper end of the first pusher 230 is secured to the slider 250 via screws. The roller 290 is provided with a screw, and the slider 250 is provided with a second through-hole 251. After passing through the second through-hole 251, the screw engages with the nut 260, thereby mounting the roller 290 on the slider 250. The first pusher 230 is also fixedly connected to the slider 250. Within the constraints of the linear bearing 240, the roller 290 can move in the vertical direction or rotate about a vertical axis. However, within the constraints of the inner surface of the chute 271, the slider 250 cannot rotate about a vertical axis, meaning that the roller 290 can only move in the vertical direction.

[0086] The first pusher 230 contacts the first guide 320 and the second guide 330 via the roller 290, thereby reducing friction. Furthermore, the roller 290 can only move in the up-and-down direction. Once mounted on the first mounting base 220, the roller 290 is not easily displaced. The roller 290 precisely mates with the first guide 320 and the second guide 330, allowing it to move along a fixed path within the first and second guides 320 and 330.

[0087] Reference Figure 1 When the first pusher 230 driven by the first driving assembly 210 passes through the first guide member 320, the roller 290 rolls along the first inclined surface 321, thereby the first pusher 230 can move from the first position to the second position. Figure 5 When the first pusher 230 driven by the first driving assembly 210 passes through the second guide member 330 , the roller 290 rolls along the second inclined surface 331 , thereby the first pusher 230 can move from the second position to the first position.

[0088] Specifically, the first inclined surface 321 can be a plane, a curved surface or other curved surface. The second inclined surface 331 can be a plane, a curved surface or other curved surface. Figure 1 In some embodiments of the present application, the moving direction of the first pusher 230 driven by the first driving component 210 is set as the first direction, and there are multiple first pushers 230, and the multiple first pushers 230 are arranged at intervals along the first direction; the number of the limiting members 310 and the first pushers 230 is the same, and the limiting members 310 are used to detachably fix the first pushers 230 in the second position one by one.

[0089] By providing a plurality of first pushing members 230 , the material moving device can move a plurality of products 400 at the same time, and the efficiency of moving the products 400 by the material moving device is higher.

[0090] Specifically, the number of the first pushing members 230 may be two, three, four or other numbers.

[0091] Reference Figure 7 In some embodiments of the present application, the material transfer device further includes a second material transfer module 500, which includes a second mounting seat 510, a second pusher 520, and a second drive assembly 530. The second pusher 520 is mounted on the second mounting seat 510. The second drive assembly 530 is used to drive the second mounting seat 510 to move, so that the second pusher 520 pushes the product 400 carried by the carrier 100.

[0092] By adding the second material moving module 500, the material moving device can move the product 400 along different paths at the same time. At this time, the material moving device can be used for loading and unloading, and the material moving device is more efficient in transferring materials.

[0093] Specifically, the specific structure of the second driving assembly 530 refers to the first driving assembly 210 and will not be repeated here.

[0094] Reference Figure 8 In some embodiments of the present application, the carrier 100 includes a bottom plate 110, a top plate 120, a first limiting plate 130, and a second limiting plate 140. The top plate 120, the first limiting plate 130, and the second limiting plate 140 are all located above the bottom plate 110, and the top plate 120, the first limiting plate 130, and the second limiting plate 140 are all fixed to the bottom plate 110 by fasteners. The bottom plate 110 is provided with a bearing surface 111. The top plate 120, the first limiting plate 130, and the bearing surface 111 jointly define a first guide groove 150, and the top plate 120, the second limiting plate 140, and the bearing surface 111 jointly define a second guide groove 160.

[0095] The first material moving module 200 is used to drive the product 400 to move in the first guide groove 150, and the product 400 moves from the right end to the left end of the bottom plate 110, thereby achieving loading. The second material moving module 500 is used to drive the product 400 to move from the left to the right in the second guide groove 160, thereby achieving unloading.

[0096] Reference Figure 7 In an improved solution of the above embodiment, the movement direction of the second pusher 520 is set as the second direction (for example, the second direction is clockwise (viewed from top to bottom)), and there are multiple second pushers 520, and the multiple second pushers 520 are arranged at intervals along the second direction.

[0097] By providing a plurality of second pushing members 520 , the material moving device can move a plurality of products 400 at the same time, and the efficiency of moving the products 400 by the material moving device is higher.

[0098] Specifically, the number of the second pushing members 520 can be two, three, four or other numbers.

[0099] Reference Figure 9 , according to the leakage testing device of the second embodiment of the present application, includes a material moving device and a sealing detection device 600. The sealing detection device 600 includes a vacuum pumping assembly 610, a tank body 620, a detection assembly 630, a tank cover 640 and a third driving assembly 650. The tank body 620 is provided with a receiving groove 621, and the receiving groove 621 is provided with an opening 622. The third driving assembly 650 is used to drive the tank cover 640 to move to the third position or the fourth position, and the third position is below the fourth position. When the tank cover 640 is in the third position, the tank cover 640 opens the opening 622. When the tank cover 640 is in the fourth position (refer to Figure 8 ), the can lid 640 closes the opening 622. The first material transfer module 200 is used to move the product 400 carried on the carrying surface 111 onto the can lid 640 in the third position. The vacuum assembly 610 is used to extract the gas in the receiving tank 621; the detection assembly 630 is used to detect the air pressure in the receiving tank 621.

[0100] The leakage testing equipment according to the embodiment of the present application has at least the following beneficial effects: by using the above-mentioned material moving device, it is helpful to improve the space utilization of the leakage testing equipment, and the installation and use of the leakage testing equipment are more convenient.

[0101] Specifically, the third driving assembly 650 may include one of a linear motor, an air cylinder, an oil cylinder, a motor-driven rack and pinion mechanism, a motor-driven crank slider mechanism, a motor-driven synchronous wheel and belt mechanism, and a motor-driven sprocket and chain mechanism.

[0102] It should be noted that when the can lid 640 moves to the third position, the upper surface of the can lid 640 is flush with the supporting surface 111. At this time, the first material transfer module 200 can move the product 400 carried by the supporting surface 111 onto the can lid 640. Thereafter, the third drive assembly 650 drives the can lid 640 to rise and move to the fourth position. At this time, the product 400 is located in the closed receiving groove 621.

[0103] When the opening 622 of the receiving tank 621 is closed, the vacuum assembly 610 (e.g., a vacuum pump) evacuates the receiving tank 621 to a set vacuum level and maintains the vacuum level for a period of time. During this period of time, the detection assembly 630 continuously detects the vacuum level of the receiving tank 621. If the difference between the vacuum level of the receiving tank 621 and the set vacuum level is within the allowable range, it indicates that the gas in the product 400 has not leaked into the receiving tank 621 and the product 400 is well sealed. If the difference between the vacuum level of the receiving tank 621 and the set vacuum level is large, it indicates that the gas in the product 400 has leaked into the receiving tank 621 and the product 400 is not well sealed.

[0104] Reference Figure 10In some embodiments of the present application, the leakage testing equipment further includes a turntable 700 , and a plurality of sealing detection devices 600 are provided. The sealing detection devices 600 are all installed on the turntable 700 , and the sealing detection devices 600 are arranged at intervals along the rotation direction of the turntable 700 .

[0105] By providing a plurality of sealing detection devices 600 , the sealing performance of a plurality of products 400 can be detected simultaneously, and the sealing detection efficiency is high.

[0106] In some embodiments of the present application, the leakage testing device further includes a conveyor belt, the turntable 700 is located on the left side of the bottom plate 110, and the conveyor belt is located on the right side of the bottom plate 110. The conveyor belt is located in the channel 170 of the carrier 100 and is used to transport the product 400 from front to back.

[0107] When the conveyor belt conveys the product 400 to the vicinity of the first mounting seat 220 , the first material transfer module 200 transfers the product 400 from the conveyor belt to the carrying surface 111 , and transfers the product 400 through the first guide groove 150 to the can cover 640 of a sealing detection device 600 .

[0108] After the seal detection device 600 completes the inspection, it is driven by the turntable 700 to rotate to the vicinity of the second mounting base 510. The second mounting base 510 transfers the inspected product 400 on the can lid 640 to the supporting surface 111, passes the product 400 through the second guide groove 160, and is transferred to the conveyor belt again, thus completing the inspection of the product 400.

[0109] The embodiments of the present application have been described in detail above with reference to the accompanying drawings. However, the present application is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features of the embodiments can be combined with each other unless there is a conflict.
