Description

Technical Field

[0001] This invention relates to the field of nasal spray applicator processing and assembly technology, and more particularly to a nasal spray applicator assembly machine. Background Technology

[0002] Nasal mucosal administration is considered a method of drug delivery where drugs can be absorbed rapidly and efficiently. The nasal mucosa cells have numerous microvilli, significantly increasing the effective absorption area. The submucosal cells are richly supplied with blood vessels and lymphatic vessels, allowing drugs to directly enter the systemic circulation after absorption. Furthermore, the metabolic activity of enzymes in the nasal cavity is far less than in the gastrointestinal tract. Current nasal spray devices typically consist of a drug storage and extrusion section. These products require separate manufacturing and assembly, followed by testing for robustness to prevent loosening and poor sealing, which could lead to failure. However, current technology lacks dedicated machinery for manufacturing such devices, requiring customization based on specific product needs. This results in low assembly efficiency and an inability to adjust the assembly process to suit different product applications.

[0003] For example, a Chinese patent document, "An Assembly and Testing Device for a Nasal Spray Pump," with publication number CN110524246A, discloses a device comprising a turntable module, a transmission module, a feeding module, a distributing module, a picking module, a pressing module, and a testing module. The turntable module and the transmission module are located within the space formed by the feeding module, the distributing module, the picking module, the pressing module, and the testing module. The turntable module includes a main plate, a lower auxiliary plate, an upper auxiliary plate, a cam divider, a linear bearing, an upper spring fixing block, a lower spring fixing block, an encoder follower shaft, and an encoder. The main plate is mounted on the cam divider. The encoder follower shaft is mounted on the output shaft of the cam divider, and the encoder is mounted on the encoder follower shaft. The turntable module has multiple workstations. However, this design is complex in structure, has limited efficiency, and cannot adjust the pressing process. Summary of the Invention

[0004] To address the limited assembly efficiency of nasal spray applicators in existing technologies, this invention provides a nasal spray applicator assembly machine that can automatically assemble the tube and cap of the nasal spray applicator, and distinguish and recycle defective nasal spray applicators, thereby improving the yield rate.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A nasal spray applicator assembly machine includes: an installation plate, on both sides of which are respectively provided a cap fixing part and a tube fixing part, which move towards or away from the installation plate as the installation plate rotates; the installation plate is connected to a detection part, which is provided with a detection mechanism that abuts against the top of the tube, and the detection mechanism distinguishes applicators with different assembly results according to the different heights of the top of the tube. The mounting plate is a circular component with mounting slots arranged in an edge array. The mounting slots are used to snap the tube in place and rotatably connect it to the tube. The tube fixing part is located on the upper side of the mounting plate, corresponding to the mounting slots. The tube fixing part includes a push rod that can extend into the tube within the mounting slot. The lowest point of the push rod's movement range is at the bottom of the tube, and the highest point is at the upper surface of the mounting plate. The upper surface of the mounting slot is lower than the upper surface of the mounting plate. The cap fixing part is located on the lower side of the mounting plate. The uppermost point of the cap fixing part's movement range is at the lowest point of the push rod's movement range. It is used to push the cap upwards to the lower end face of the tube and install it. The detection part is used to detect the relative position of the installed tube and cap. The detection part includes a qualified height range, and medication dispensers outside the qualified height range are screened and rejected. This system can quickly and reliably assemble the tube and cap of the medication dispenser, and simultaneously classify the assembled medication dispensers according to the height of the cap, rejecting those that are not properly assembled.

[0007] Preferably, the detection mechanism is connected to a recycling mechanism. The detection mechanism includes a detection plate, and a detection ring is provided on the outside of the detection plate that is higher than the detection plate. The detection ring surrounds the detection plate and extends gradually away from the detection plate. The recycling mechanism is located in the middle of the detection ring and is located on both sides of the detection ring, respectively. The detection disc is a circular disc arranged horizontally and tangent to the mounting disc. A detection ring with a diameter slightly larger than the detection disc is located above it. The end of the detection ring connects to the detection disc and gradually increases in height as it surrounds the detection disc. The inner wall of the detection ring abuts against the top of the tube. The inner wall of the detection ring and the detection disc respectively abut and fix the upper and lower ends and inner and outer sides of the tube. This screens drug delivery devices whose top height does not reach the detection ring and those whose top height exceeds the detection ring. It can screen assembled drug delivery devices. The position of the retrieval mechanism can move relative to the detection ring and rotate relative to the detection disc, allowing for adjustment of the screening height and thus enabling the screening of different products. The detection disc has a mounting slot corresponding to the mounting disc. The detection disc and the mounting disc rotate synchronously. The detection disc follows the rotation of the mounting disc and retrieves the assembled drug delivery device from the mounting disc at the same speed. Both the mounting slots of the detection disc and the mounting disc can engage half of the tube, thus achieving seamless transfer.

[0008] Preferably, the recovery mechanism includes a pusher that pushes the drug delivery device off the detection plate by airflow or mechanical means; and a recovery chamber corresponding to the pusher, with the recovery chamber and pusher located on opposite sides of the detection ring. When the pusher pushes the drug delivery device out by airflow, the pusher includes a nozzle located below the detection plate, which generates a downward-sloping airflow from the center of the detection plate towards the lower edge of the plate, pushing the airflow towards the cap and tube connection. When the pusher pushes the drug delivery device out mechanically, the pusher includes a push rod located below the detection plate and parallel to it, which pushes the cap and tube connection radially along the detection plate. The recovery chamber includes a recovery channel with its inlet corresponding to the pusher and located on opposite sides of the detection ring below the pusher. The recovery chamber and pusher have a fixed relative position, but can move synchronously by rotating around the center of the detection plate. The recovery mechanism can be used to reject and recover drug delivery devices that are not up to standard after assembly, as needed.

[0009] Preferably, the tube fixing part includes a rigid moving mechanism and an elastic moving mechanism connected in sequence. The rigid moving mechanism is displaced by changes in height, and the elastic moving mechanism is located between the tube and the rigid moving mechanism and generates a reverse elastic force after abutting the bottom of the tube. The tube fixing part includes a push rod that can extend into the tube in the mounting groove. The upper end of the push rod is connected to a push rod spring in an elastic moving mechanism. The upper end of the push rod spring is connected to a guide rod mounting plate, which rotates coaxially and synchronously with the mounting plate. Near the center of the guide rod mounting plate is a light shaft in a rigid moving mechanism, which is connected to a guide plate. A tube fixing punch is located at the upper end of the light shaft, and a light shaft spring is sleeved on the outside of the light shaft. The two ends of the light shaft spring are connected to the tube fixing punch and the guide plate, respectively. A first height inclined block, a gradually increasing annular component, abuts above the tube fixing punch. The tube fixing punch moves up and down as the height of the first height inclined block changes. The push rod spring has a first working mode and a second working mode. In the first working mode, the push rod spring is only subjected to pressure from the guide rod mounting plate and exerts pressure on the push rod. In the second working mode, the push rod spring is subjected to pressure from both the guide rod mounting plate and the push rod. This provides a damping effect after installation, preventing excessive pressure on the tube.

[0010] Preferably, the cap fixing part includes a cap support block connected to a support block push rod. The support block push rod reciprocates and pushes the cap support block, which is not on the center line, to move. The cap support block is an annular disc. The edge of the cap support block has an array of cap mounting slots corresponding to the mounting slots on the mounting disc. The cap support block rotates coaxially and synchronously with the mounting disc, and the cap mounting slots engage with the cap. A push rod spring is sleeved on the outside of the support block push rod. A cap fixing punch is provided at the lower end of the support block push rod. A second height inclined block abuts below the cap fixing punch. The second height inclined block is an annular component with a reciprocatingly changing height. The second height inclined block has more than one bend with the same height change, causing the height of the cap fixing punch to reciprocate. The cap fixing punch applies the same reciprocating thrust to the cap as the height of the second height inclined block changes. This generates a repetitive force to assemble the cap with the tube from bottom to top, and the installation efficiency can be changed according to the arrangement of the second height inclined block.

[0011] Preferably, the outer side of the mounting plate is provided with a cap inlet and a tube inlet, both of which include an inlet connected to a slide rail. The slide rail and the inlet have a height difference. An obliquely arranged air-blowing mechanism is located at the connection between the slide rail and the inlet. The slide rail guides the cap and cap into the inlet respectively. The inlet connects to the cap mounting slot of the cap holder and the mounting slot of the mounting plate, respectively. The airflow generated by the air-blowing mechanism at the inlet creates an airflow at the same angle as the slide rail. The airflow blows the cap or tube that has slid to the inlet into the cap mounting slot of the cap holder and the mounting slot of the mounting plate, respectively, ensuring tight contact between the cap or tube and the mounting slot of the mounting plate. This allows for separate fixation of the cap and tube, preventing installation failures caused by loosening of the cap and tube during assembly and improving the yield rate.

[0012] Preferably, the mounting plate has an inlet plate and an outlet plate abutting its edge. Both the inlet and outlet plates are on the same horizontal plane as the mounting plate and rotate synchronously. The inlet plate is used to transfer the tube into the mounting plate, and the outlet plate connects to the detection unit. Both the inlet and outlet plates have mounting grooves identical to and corresponding to the mounting plate. These mounting grooves engage with the side wall of the tube. The inlet and outlet plates are located on opposite sides of the mounting plate. The inlet plate conveys unmounted tubes into the mounting plate, and the outlet plate delivers the assembled drug delivery device from the mounting plate to the detection unit. This system enables efficient and rapid tube transport, allowing each tube to be independently transported and assembled, improving tube transport efficiency and facilitating positioning, thereby increasing assembly efficiency.

[0013] Preferably, the mounting plate is connected to a main shaft, with both ends of the main shaft connected to the tube fixing part and the cap fixing part, respectively. The tube fixing part and the cap fixing part abut against both ends of the mechanism frame. The main shaft drives the mounting plate to rotate, simultaneously causing the tube fixing part and the cap fixing part to rotate. The first height wedge and the second height wedge are fixed at the upper and lower ends of the mechanism frame, respectively, and face the mounting plate. The first height wedge and the second height wedge do not rotate with the mounting plate. The inlet plate and the outlet plate are connected to the lower end face of the mechanism frame. This design allows for the simultaneous arrangement of the assembly mechanism and the transmission mechanism within the mechanism frame, saving layout space.

[0014] The present invention has the following advantages:

[0015] (1) It can quickly and reliably assemble the tube and cap of the drug delivery device, and classify the assembled drug delivery devices according to the height of the cap, and remove the unqualified drug delivery devices; (2) The detection plate rotates with the installation plate and picks up the assembled drug delivery device from the installation plate at the same speed. The installation slots of the detection plate and the installation plate can both lock half of the tube, thereby achieving seamless transmission; (3) It can efficiently and quickly transport the tube, so that each tube can be independently transported and assembled, improving the tube transport efficiency and facilitating positioning, thereby improving the assembly efficiency; (4) It can generate a damping effect after installation, avoiding excessive pressure on the tube; (5) It can generate a repeating force to assemble the cap with the tube from bottom to top, and the installation efficiency can be changed according to the arrangement of the second height inclined block.

[0021] The following specific embodiments illustrate the implementation of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] like Figs. 1-2 As shown, in a preferred embodiment, the present invention discloses a nasal spray applicator assembly machine, comprising: an installation plate 1, wherein a cap fixing part and a tube fixing part are respectively provided on both sides of the installation plate 1, and the cap fixing part and the tube fixing part move toward or away from the installation plate 1 simultaneously as the installation plate 1 rotates; the installation plate 1 is connected to a detection part, the detection part is provided with a detection mechanism that abuts against the top of the tube, and the detection mechanism distinguishes applicators with different assembly results according to the different heights of the top of the tube. Mounting disc 1 is a disc with mounting grooves arranged in an edge array. The mounting grooves are used to snap the tube in place and are rotatably connected to the tube. The tube fixing part is located on the upper side of mounting disc 1 and corresponds to the mounting groove. The tube fixing part includes a push rod that can extend into the tube inside the mounting groove. The lowest point of the push rod's movement range is at the bottom of the tube, and the highest point of the push rod's movement range is at the upper surface of mounting disc 1. The upper surface of the mounting groove is lower than the upper surface of mounting disc 1. The cap fixing part is located on the lower side of mounting disc 1. The uppermost point of the cap fixing part's movement range is at the lowest point of the push rod's movement range. It is used to push the cap upward to the lower end face of the tube and install it. The detection part is used to detect the relative position of the tube and cap after installation. The detection part includes a qualified height range and screens out and rejects the drug delivery device outside the qualified height range.

[0023] During use, the cap fixing part moves the cap toward the mounting plate 1, and the tube fixing part presses the tube into the mounting groove. When the cap fixing part reaches the uppermost point of the moving range and the top rod reaches the lowest point of the moving range, the assembly is completed. After the assembled drug delivery device reaches the detection part, if the height of the tube relative to the cap exceeds the qualified height range, it proves that the installation of the tube and the cap is unqualified.

[0024] The detection mechanism is connected to the recycling mechanism 2. The detection mechanism includes a detection plate, and a detection ring is provided on the outside of the detection plate that is higher than the detection plate. The detection ring surrounds the detection plate and extends gradually away from the detection plate. The recycling mechanism 2 is located in the middle of the detection ring and is located on both sides of the detection ring, respectively, with the detection plate. The detection disc is a circular disc arranged horizontally and tangent to the mounting disc 1. A detection ring with a diameter slightly larger than the detection disc is located above it. The end of the detection ring is connected to the detection disc, and its height gradually increases as it surrounds the detection disc. The inner wall of the detection ring abuts against the top of the tube. The inner wall of the detection ring and the detection disc respectively abut and fix the upper and lower ends and inner and outer sides of the tube. This screens drug delivery devices whose top height does not reach the detection ring and those whose top height exceeds the detection ring. It can screen assembled drug delivery devices. The position of the recovery mechanism 2 can move relative to the detection ring and rotate relative to the detection disc, allowing for adjustment of the screening height and thus enabling the screening of different products. The detection disc has a mounting slot corresponding to the mounting disc 1. The detection disc and mounting disc 1 rotate synchronously. The detection disc follows the rotation of the mounting disc 1 and retrieves the assembled drug delivery device from the mounting disc 1 at the same speed. Both the mounting slots of the detection disc and the mounting disc 1 can engage half of the tube, thus achieving seamless transmission.

[0025] During use, the position of the recovery mechanism 2 relative to the detection ring is adjusted so that the recovery mechanism 2 corresponds to the target height of the detection ring, thereby determining the qualified and unqualified ranges. When the height of the drug delivery device does not match the qualified height, the two ends of the drug delivery device are not fixed by the inner wall of the detection ring and the detection plate, causing the drug delivery device to be rejected and recovered by the recovery mechanism 2. When the height of the drug delivery device exceeds the recovery mechanism 2, the drug delivery device is rejected when passing through the recovery mechanism 2 due to the lack of fixation by the inner wall of the detection ring.

[0026] The recovery mechanism 2 includes a pusher that pushes the drug delivery device off the detection plate by airflow or mechanical means; and a recovery chamber corresponding to the pusher, with the recovery chamber and pusher located on opposite sides of the detection ring. When the pusher pushes the drug delivery device out by airflow, the pusher includes a nozzle located below the detection plate, which generates a downward-sloping airflow from the center of the detection plate towards the lower edge of the plate, pushing the airflow towards the cap and tube connection. When the pusher pushes the drug delivery device out mechanically, the pusher includes a push rod located below the detection plate and parallel to it, which pushes the cap and tube connection radially along the detection plate. The recovery chamber includes a recovery channel with its inlet corresponding to the pusher and located on opposite sides of the detection ring below the pusher. The recovery chamber and pusher have a fixed relative position, but can rotate synchronously around the center of the detection plate to move.

[0027] In use, the airflow is pushed to blow open loosely assembled tubes and caps, and blows the caps out of the detection plate. This causes the tube height to drop, and at the same time, it loses the fixation of the inner wall of the detection ring and the mounting groove. As a result, the tube is also blown out of the detection plate, thus eliminating defective products.

[0028] When the pusher is a push rod, if the assembly is correct, the upper end of the drug delivery device is abutted against the inner wall of the detection ring, and the lower end of the drug delivery device is located in the groove of the detection plate; the push rod cannot push the drug delivery device out. If the assembly is incorrect, the middle part of the drug delivery device abuts against the inner wall of the detection ring, and the push rod pushes the tube, loosening the connection between the tube and the cap, thus causing the cap to be pushed off the detection plate, and the tube to be pushed off the detection plate.

[0029] The pipe fixing part includes a rigid moving mechanism and an elastic moving mechanism connected in sequence. The rigid moving mechanism is displaced by changes in height, and the elastic moving mechanism is located between the pipe and the rigid moving mechanism and generates a reverse elastic force after abutting the bottom of the pipe. The tube fixing part includes a push rod that can extend into the tube in the mounting groove. The upper end of the push rod is connected to a push rod spring 10 in an elastic moving mechanism. The upper end of the push rod spring 10 is connected to a guide rod mounting plate. The guide rod mounting plate rotates synchronously with the mounting plate 1 on the same axis. The guide rod mounting plate is connected to a light shaft in a rigid moving mechanism near its center. The light shaft is connected to a guide plate. The upper end of the light shaft is provided with a tube fixing punch. A light shaft spring is sleeved on the outside of the light shaft. The two ends of the light shaft spring are connected to the tube fixing punch and the guide plate, respectively. A first height inclined block is abutted above the tube fixing punch. The first height inclined block is a ring-shaped piece with gradually increasing height. The tube fixing punch moves up and down as the height of the first height inclined block changes. The push rod spring 10 has a first working mode and a second working mode. In the first working mode, the push rod spring 10 is only subjected to the pressure of the guide rod mounting plate and exerts pressure on the push rod. In the second working mode, the push rod spring 10 is subjected to the pressure of both the guide rod mounting plate and the push rod.

[0030] In use, when the tube fixing punch rotates to the first height inclined block, the tube fixing punch is pushed downward. The downward movement of the tube fixing punch drives the optical axis to move downward. The optical axis movement is connected to the rotation of the guide plate. The optical axis movement drives the guide rod mounting plate to move. The downward movement of the guide rod mounting plate drives the top rod to move through the top rod spring 10. The top rod moves until its end abuts against the bottom of the tube. At this time, the top rod spring 10 is in the first working mode. If the top rod mounting plate continues to move downward, the top rod spring 10 is in the second working mode.

[0031] The cap fixing part includes a cap support block 5, which is connected to a support block push rod 6. The support block push rod 6 is used for reciprocating motion and pushing the cap support block 5, which is not on the center line, to move. The cap support block 5 is a circular disc. The edge of the cap support block 5 has an array of cap mounting slots corresponding to the mounting slots on the mounting plate 1. The cap support block 5 rotates coaxially and synchronously with the mounting plate 1, and the cap mounting slots engage with the cap. A push rod spring is sleeved on the outside of the support block push rod 6. A cap fixing punch is provided at the lower end of the support block push rod 6. A second height inclined block abuts below the cap fixing punch. The second height inclined block is a circular ring with a reciprocating and cyclically changing height. The second height inclined block has more than one bend with the same height change. The second height inclined block reciprocates and changes the height of the cap fixing punch. The cap fixing punch applies the same reciprocating thrust to the cap as the height of the second height inclined block changes.

[0032] When in use, when the cap fixing punch follows the installation plate 1 to the second height inclined block, the cap fixing punch moves upward due to the height change of the second height inclined block. The movement of the cap fixing punch drives the support block push rod 6 to move upward, and the upward movement of the support block push rod 6 drives the cap support block 5 to move. At the same time, the up-and-down reciprocating motion allows the cap support block 5 to hit the bottom of the cap multiple times to connect and fasten the cap to the bottom of the tube.

[0033] The outer side of the mounting plate 1 is provided with a cap inlet 3 and a tube inlet 4 in sequence. Both the cap inlet 3 and the tube inlet 4 include an inlet, which is connected to a slide. The slide and the inlet have a height difference. An obliquely arranged air blowing mechanism is provided at the connection between the slide and the inlet. The slide drops the cap and the cap into the inlet respectively. The inlet is connected to the cap mounting groove of the cap support block 5 and the mounting groove of the mounting plate 1 respectively. The airflow generated by the air blowing mechanism at the inlet produces an airflow at the same angle as the slide. The airflow blows the cap or tube that has slid to the inlet into the cap mounting groove of the cap support block 5 and the mounting groove of the mounting plate 1 respectively, and tightly abuts the cap or tube against the cap mounting groove of the cap support block 5 and the mounting groove of the mounting plate 1 respectively.

[0034] In use, the caps are inserted into the slide rail of the cap inlet 3. The caps slide along the slide rail under the influence of gravity to the inlet and are then blown into the cap mounting slot by the air blowing mechanism. Similarly, the tubes are inserted into the slide rail of the tube inlet 4. The tubes slide along the slide rail under the influence of gravity to the inlet and are then blown into the mounting slot by the air blowing mechanism. The slide rails are connected to an arrangement mechanism, which is a rotating spiral channel that allows for adaptive adjustment of the position and orientation of the tubes or caps.

[0035] The mounting plate 1 has an inlet plate 7 and an outlet plate 8 abutting its edge. Both inlet plate 7 and outlet plate 8 are on the same horizontal plane as the mounting plate 1 and rotate synchronously. The inlet plate 7 is used to transfer the tube into the mounting plate 1, and the outlet plate 8 is connected to the detection unit. Both inlet plate 7 and outlet plate 8 have mounting grooves that are identical and corresponding to those on the mounting plate 1. The mounting grooves engage with the side walls of the tubes. The inlet plate 7 and outlet plate 8 are located on opposite sides of the mounting plate 1. The inlet plate 7 is used to transfer unassembled tubes into the mounting plate 1, and the outlet plate 8 is used to transfer the assembled drug delivery device from the mounting plate 1 to the detection unit. This system enables efficient and rapid tube transport, allowing each tube to be independently transported and assembled, improving tube transport efficiency and facilitating positioning.

[0036] During use, the tubes before and after assembly can be conveyed in a fixed order and position through the inlet disc 7 and the outlet disc 8, which avoids the tubes or caps not being able to correspond during the assembly process, thus reducing the assembly efficiency. At the same time, the synchronous control of the inlet disc 7 and the outlet disc 8 links the assembly process with the feeding and discharging process, further improving the processing efficiency.

[0037] The mounting plate 1 is connected to a main shaft 9, with its two ends connected to a tube fixing part and a cap fixing part, respectively. The tube fixing part and the cap fixing part abut against the two ends of the mechanism frame. The main shaft 9 is used to drive the mounting plate 1 to rotate, which in turn drives the tube fixing part and the cap fixing part to rotate. The first height inclined block and the second height inclined block are fixed at the upper and lower ends of the mechanism frame and face the mounting plate 1, respectively. The first height inclined block and the second height inclined block do not rotate with the mounting plate 1. The inlet plate 7 and the outlet plate 8 are connected to the lower end face of the mechanism frame.

[0038] When in use, the frame can be arranged according to the requirements to achieve the desired functionality, saving factory space.

[0039] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
