Description

Technical Field

[0001] This utility model belongs to the field of medical equipment assembly technology, and specifically refers to a drip filter feeding device. Background Technology

[0002] The drip chamber is a key component of an infusion set, generally consisting of the drip chamber body, puncture device, filter, and sheath. To ensure hygiene and safety during the assembly process, the various components of the drip chamber need to be assembled automatically in a sterile workshop.

[0003] Chinese utility model patent with announcement number "CN218396825U" discloses a gasket feeding mechanism, including a horizontal conveying vibratory feeder mechanism, a misalignment component, and a picking mechanism. The picking mechanism includes a picking assembly, whose movement is controlled by a longitudinal picking drive mechanism and a transverse picking drive mechanism. The picking assembly includes a picking rod, which is slidably connected to a gasket pressing block. The gasket pressing block is fixed on a lifting bracket, which is fixedly connected to the longitudinal picking drive mechanism. The picking rod is connected to the longitudinal picking rod drive mechanism. The gasket is more securely fixed by passing the picking rod through a cut in the gasket.

[0004] However, since the drip filter has no cut in the middle, the material handling component in the above technical solution cannot be directly applied to handle the drip filter. Moreover, since the filter is irregular in shape, if the material handling component is simply replaced with a conventional gripper or robotic arm component, it will be inconvenient to handle and the gripping will not be firm enough. During the feeding process, the filter is prone to loosening or flipping, which will affect the subsequent assembly. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a drip filter feeding device that adapts to the shape and structure of the filter and clamps it more firmly.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A drip filter feeding device includes a horizontal conveying vibratory plate mechanism, a misalignment mechanism, and a material picking mechanism. The material picking mechanism includes a material picking mounting frame and a material picking lateral movement component fixedly connected to the mounting frame. A material picking lifting component is connected to the material picking lateral movement component and can drive the material picking lifting component to move. A clamping component is connected to the material picking lifting component and can drive the clamping component to lift. The clamping component includes material picking fingers and a clamping drive component that drives the material picking fingers to open and close. The upper end of the material picking fingers is connected to the clamping drive component, and the lower inner side is provided with an arc-shaped clamping groove. A clamping pressure block is also fixedly provided on the clamping component. The lower part of the clamping pressure block is located between two clamping grooves, and the lower end surface of the clamping pressure block is flat.

[0008] This solution uses a flat-feed vibratory feeder mechanism to adjust and transport the filter discs, and a misalignment mechanism to stagger the filter discs, ensuring that only one filter disc is picked up at a time. Then, the filter disc is picked up and transferred by a material picking mechanism. During material picking, the material picking clamp has an arc-shaped picking groove on its finger, which fits more closely with the outer circumference of the filter disc, making it easier to hold and providing better grip. At the same time, the clamping pressure block supports the upper end of the filter disc, further preventing the filter disc from flipping or loosening during the picking process.

[0009] In this drip filter feeding device, the misalignment mechanism includes a misalignment mounting frame and a misalignment lateral movement component fixed on the misalignment mounting frame. A receiving connector is fixed on the misalignment lateral movement component and can drive the receiving connector to move laterally. A receiving block is fixed on the receiving connector. The receiving block is provided with a receiving port, a receiving groove and a support block. The receiving port is connected to the receiving groove.

[0010] When the horizontal conveying vibratory feeder mechanism delivers the filter sheet to the designated position, the receiving port connects with the horizontal conveying vibratory feeder mechanism. The filter sheet passes through the receiving port into the receiving groove and falls onto the support block. Subsequently, the offset transverse shifting component drives the receiving block to move laterally to close the connection between the receiving port and the horizontal conveying vibratory feeder mechanism, ensuring that only one filter sheet enters the receiving groove at a time. This facilitates subsequent clamping and also avoids multiple filter sheets entering at the same time, which could lead to squeezing or positional displacement.

[0011] In this drip filter feeding device, a staggered lifting component is fixedly connected to the outside of the receiving connector. A lifting connecting plate is fixedly connected to the upper end of the staggered lifting component and can drive the lifting connecting plate to rise and fall. A top material block is fixedly connected to the lifting connecting plate. The top material block is provided with a positioning column and a positioning groove. The receiving groove is vertically connected. The positioning column can be inserted into the receiving groove under the action of the staggered lifting component. The height of the positioning column is higher than the height of the support block.

[0012] The staggered lifting assembly raises the top material block and inserts the positioning pins into the through-hole receiving slots. A space for accommodating the filter sheet is formed between every two positioning pins, allowing for precise positioning of the delivered filter sheet, reducing errors and improving gripping accuracy. When the staggered lateral movement assembly moves the receiving block laterally and closes the receiving port, the staggered lifting assembly lowers the top material block. At this point, the two receiving slots are emptied, facilitating the insertion of the gripping fingers to pick up the filter sheet.

[0013] In this drip filter feeding device, a material receiving transition block is also fixedly connected to the misaligned mounting frame. The upper end face of the material receiving transition block is provided with a transition groove, and the openings at both ends of the transition groove correspond to the flat conveying vibrating plate mechanism and the material receiving port, respectively.

[0014] By setting a receiving transition block between the receiving block and the flat conveying vibratory plate mechanism, the filter sheet enters the transition groove first, which can avoid the deviation caused by vibration. At the same time, it guides the path of the filter sheet conveying, so that the filter sheet can fall into the preset position more accurately. The setting of the receiving transition block can also better cooperate with the misalignment mechanism for misalignment.

[0015] In this drip filter feeding device, a fixed frame is fixedly connected to the receiving transition block, and a positioning detection component is installed on the fixed frame. The positioning detection component can detect the positioning status of the filter and control the misalignment component to perform corresponding actions, realizing a high degree of automated production.

[0016] In this drip filter feeding device, the horizontal conveying vibratory feeder mechanism includes a vibratory feeder mounting frame, a vibratory feeder, a vibratory feeder dispensing assembly, a feeding track, and a vibration assembly. The vibration assembly drives the vibratory feeder to adjust the posture of the filter and convey it through the feeding track. The vibratory feeder dispensing assembly is used to dispense the filter.

[0017] In this drip filter feeding device, the feeding track includes a flat feeding plate and a cover plate. The flat feeding plate is equipped with a feeding trough, and the outlet of the feeding trough corresponds to the opening of the transition trough. The width of the feeding trough is adapted to the diameter of the filter. Multiple filter sheets are fed in a queue, and the outlet of the feeding trough corresponds to the opening of the transition trough to ensure that only one filter sheet passes through at a time.

[0018] Compared with the prior art, the technical effects of this utility model are as follows:

[0019] First, this drip filter feeding device is better suited to the shape of the filter. With the inner arc-shaped clamping groove of the clamping fingers and the clamping pressure block, the filter can be clamped more conveniently and firmly, while also preventing the filter from flipping or loosening during transportation.

[0020] Secondly, the drip filter feeding device ensures that only one filter is in the clamping slot each time it is clamped through the staggered mechanism, avoiding multiple filter sheets from being squeezed and shifted. At the same time, the position of the filter sheet is positioned by the positioning column, which improves the clamping accuracy.

[0021] Third, the positioning column and receiving block of this drip filter feeding device are separate. After the filter is positioned, the staggered lifting component can drive the positioning column to descend and disengage, leaving an empty receiving slot so that the gripper can extend in to complete the gripping of the filter, thus improving the gripping accuracy.

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0033] like Figure 1 As shown, a drip filter feeding device includes a horizontal conveying vibratory feeder mechanism 1, a misalignment mechanism 2, and a material handling mechanism 3. The horizontal conveying vibratory feeder mechanism 1 includes a vibratory feeder mounting frame 11, a vibratory feeder 12, a vibratory feeder dispensing assembly 13, a feeding track 14, and a vibration assembly 15. The vibration assembly 15 drives the vibratory feeder 12 to adjust the posture of the filter and convey it through the feeding track 14. The vibratory feeder dispensing assembly 13 is used to dispense the filter. Further, as... Figure 9 As shown, the feeding track 14 includes a flat feeding plate 141 and a cover plate 142. The flat feeding plate 141 is provided with a feeding trough 143, and the circular filter sheets are arranged in the feeding trough 143.

[0034] Preferred, such as Figure 2 As shown, the material handling mechanism 3 includes a material handling mounting frame 31 and a material handling transverse moving component 32 fixedly connected to the material handling mounting frame 31. The material handling transverse moving component 32 is connected to a material handling lifting component 33 and can drive the material handling lifting component 33 to move. The material handling lifting component 33 is connected to a clamping component 34 and can drive the clamping component 34 to lift.

[0035] Preferred, such as Figure 3 , Figure 4 As shown, two sets of clamping components 34 are fixedly connected to the lower end of the material lifting assembly 33. Each clamping component 34 includes a material picking finger 341 and a clamping drive 342 that drives the material picking finger 341 to open and close. The clamping drive 342 is a cylinder that drives the material picking finger 341 to open and close by air pressure. The upper end of the material picking finger 341 is connected to the clamping drive 342, and the lower inner side is provided with an arc-shaped clamping groove 343, which fits more closely with the outer circumference of the filter sheet, making it easier to clamp and providing better clamping stability. A clamping pressure block 344 is also fixedly provided on the side of the clamping assembly 34. The clamping pressure block 344 is hook-shaped with a wider upper end and a narrower lower end. The hook-shaped part of the lower end of the clamping pressure block 344 extends into the two clamping grooves 343. The lower end surface of the clamping pressure block 344 is flat and can press against the upper end of the filter sheet, further preventing the filter sheet from flipping or loosening during the clamping process.

[0036] Preferred, such as Figure 5 , Figure 6 , Figure 7 As shown, the misalignment mechanism 2 includes a misalignment mounting frame 21 and a misalignment lateral movement component 22 fixedly connected to the misalignment mounting frame 21. A receiving connector 23 is fixedly connected to the misalignment lateral movement component 22 and can drive the receiving connector 23 to move laterally. A receiving block 24 is fixedly connected to the upper end of the receiving connector 23 through two connecting rods. The receiving block 24 has two receiving ports 241 on its side. The receiving block 24 has two concave receiving grooves 242 and a support block 243 inside. The two receiving ports 241 are respectively connected to the two receiving grooves 242. When the horizontal conveying vibratory feeder mechanism 1 delivers the filter sheet to the designated position, the receiving port 241 connects with the horizontal conveying vibratory feeder mechanism 1. The filter sheet passes through the receiving port 241, enters the receiving groove 242, and falls onto the support block 243. Subsequently, the offset transverse shifting component 22 drives the receiving block 24 to move laterally to close the connection between the receiving port 241 and the horizontal conveying vibratory feeder mechanism 1, ensuring that only one filter sheet enters the receiving groove 242 at a time. This facilitates subsequent clamping and also avoids multiple filter sheets entering at the same time, which could lead to squeezing or positional displacement.

[0037] Preferred, such as Figure 5 , Figure 6 , Figure 7As shown, a staggered lifting assembly 25 is fixedly connected to the outside of the receiving connector 23. A lifting connecting plate 26 is fixedly connected to the upper end of the staggered lifting assembly 25 and can drive the lifting connecting plate 26 to rise and fall. A top material block 27 is fixedly connected to the lifting connecting plate 26. Four positioning posts 271 are provided on the top material block 27. A positioning groove 272 is formed between every two positioning posts 271. In this embodiment, the receiving groove 242 is vertically connected. The support block 243 is located in the middle of each receiving groove 242. The receiving groove 242 forms two channels on both sides of the support block 243. The positioning posts 271 can be inserted into the receiving groove 242 under the drive of the staggered lifting assembly 25. The height of the positioning posts 271 is higher than the height of the support block 243. A space for positioning the filter sheet is formed between the parts of the two positioning posts 271 that are higher than the support block 243, which reduces the error of the filter sheet position and improves the accuracy of clamping. When the misaligned lateral movement component 22 moves the receiving block 24 laterally and closes the receiving port 241, the misaligned lifting component 25 moves the top block 27 down. At this time, the two receiving slots 242 are empty, making it easier for the picking fingers 341 to extend into the receiving slots 242 to pick up the filter sheet.

[0038] Preferred, such as Figure 5 , Figure 8 As shown, a receiving transition block 28 is also fixedly connected to the misalignment mounting bracket 21. The upper end face of the receiving transition block 28 is provided with a transition groove 281, and the openings at both ends of the transition groove 281 correspond to the feeding groove 143 and the receiving port 241, respectively. The filter sheet enters the transition groove 281 from the feeding groove 143 first, which can avoid the displacement caused by vibration, and at the same time guide the path of the filter sheet, so that the filter sheet can fall into the preset position more accurately. The setting of the receiving transition block 28 can also better cooperate with the misalignment mechanism 2 for misalignment.

[0039] Preferably, a fixing frame 282 is fixedly connected to the receiving transition block 28, and a positioning detection component 283 is provided on the fixing frame 282, which can detect the positioning status of the filter and control the misalignment mechanism 2 to make corresponding actions, so as to realize highly automated production.

[0040] The working principle of this drip filter feeding device is as follows:

[0041] The filter sheet is fed into the vibratory feeder 12 via the vibratory feeder feeding assembly 13. After being adjusted in attitude within the vibratory feeder 12, it is conveyed to the feeding trough 143 of the feeding track 14. The filter sheet moves along the feeding trough 143 and enters the transition trough 281. Subsequently, it is pushed by the following filter sheet and enters the receiving trough 242 between the two positioning columns 271. At this time, the positioning detection assembly 283 detects that the filter sheet is in place and controls the misalignment lateral movement assembly 22 to drive the receiving block 24 to move laterally. At the same time, the misalignment lifting assembly 25 drives the positioning column 271 to descend. The picking mechanism 3 controls the clamping assembly 34 to clamp and convey the filter sheet. The outer periphery of the filter sheet fits into the clamping groove 343 of the picking fingers 341, and the flat lower end surface of the clamping pressure block 344 presses against the upper end surface of the filter sheet, thereby achieving a more stable conveying.

[0042] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection defined by the claims of the present utility model.
