Description

Technical Field

[0001] The present invention relates to the technical field of adhesive production and preparation, and particularly to a medical adhesive production device and process. Background Art

[0002] Medical adhesives are a special type of material designed specifically for medical scenarios. They achieve the adhesion and repair between human tissues and instruments through chemical or biological actions. The production process includes the following steps: Pour the medical adhesive into a glass ampoule and seal it by melting. Place the sealed ampoule into an outer tube through an installation device. Connect a handle to one end of the outer tube, and sequentially install a filter column and a nozzle at the other end. Finally, complete the assembly of the components in the order of "handle - outer tube - glass ampoule - filter column - nozzle".

[0003] However, the connection between the handle and the outer tube is a key step. Since the outer tube usually uses a soft material (such as rubber or soft plastic) to adapt to the deformation during the extrusion of the handle, this design causes new problems in actual operation: If there are defects in the handle and the outer tube, such as deformation of either the handle or the outer tube, it will lead to misalignment between the handle and the outer tube. At this time, if the assembly of the handle and the outer tube continues, the outer tube is prone to plastic deformation due to its soft material and uneven force, while the handle will break due to excessive extrusion. The above problems are mainly due to the small alignment deviation during their assembly. Summary of the Invention

[0004] To solve the problems mentioned in the above background art, the present invention provides a medical adhesive production device and process.

[0005] The technical implementation solution of the present invention is: A medical adhesive production device includes a workbench. Above the workbench, there are several uniformly distributed material conveying racks. The workbench is fixedly connected with a fixed frame. The fixed frame is provided with an electric push rod. The workbench is slidably connected with a sliding plate fixedly connected to the telescopic end of the electric push rod. The sliding plate is slidably connected with several uniformly distributed first L-shaped frames. The number of the first L-shaped frames corresponds one-to-one with the number of the material conveying racks. It also includes a second L-shaped frame, an arc-shaped block, a sliding frame, and a rotating member. The second L-shaped frame slides along the first L-shaped frame. The arc-shaped block is fixedly connected with the second L-shaped frame. The sliding frame slides along the arc-shaped block through an electric slider. The rotating member rotates along the sliding frame, and a torsion spring is arranged between the two. The arc-shaped block is provided with a guiding component for driving the rotating member to rotate. The workbench is provided with uniformly distributed material conveying components for conveying materials. The number of the material conveying components corresponds one-to-one with the number of the material conveying racks.

[0006] Further, a displacement sensor is fixedly connected to one side of the first L-shaped frame close to the second L-shaped frame, and the telescopic part of the displacement sensor is fixedly connected to the second L-shaped frame.

[0007] Further, the guiding assembly includes a fixing plate, a first guiding rod and a telescopic frame. The fixing plate is fixedly connected to one side of the arc-shaped block close to the second L-shaped frame. The fixing plate is fixedly connected to the first guiding rod. The rotating part is fixedly connected to the telescopic frame. The first guiding rod is used to squeeze the telescopic frame.

[0008] Further, the guiding assembly further includes an arc-shaped slider and a second guiding rod. The arc-shaped slider slides along the sliding frame. The fixing plate is fixedly connected to the second guiding rod. The arc-shaped slider slides along the second guiding rod. The telescopic part of the telescopic frame slides along the arc-shaped slider. The second guiding rod is used to guide the telescopic part of the telescopic frame. A limiting assembly for restricting its position is arranged on the first L-shaped frame.

[0009] Further, the rotating part is composed of a hemisphere, an arc-shaped shell and a connecting plate. The hemisphere and the arc-shaped shell are respectively fixed on both sides of the connecting plate. The hemisphere on the rotating part rotates along the sliding frame. The center of the circle where the arc-shaped edge of the symmetric section of the arc-shaped slider is located coincides with the center of the sphere of the hemisphere on the rotating part. The center of the circle where the projection of the first guiding rod on the horizontal plane is located coincides with the center of the sphere of the hemisphere on the rotating part. The middle part of the second guiding rod in the vertical direction and the middle part of the hemisphere on the rotating part in the vertical direction are located on the same horizontal plane. The distance between the second guiding rod and the center of the sphere of the hemisphere on the rotating part gradually decreases from the side close to the fixing plate to the side far from the fixing plate.

[0010] Further, the limiting assembly includes a limiting frame, a first trapezoidal block and a second trapezoidal block. The limiting frame slides along the first L-shaped frame. A second tension spring is fixedly connected between the limiting frame and the first L-shaped frame. The limiting frame is used to limit the first L-shaped frame on the sliding plate. The first trapezoidal block is fixedly connected to the second L-shaped frame. The second trapezoidal block is fixedly connected to one side of the limiting frame close to the arc-shaped block. The first trapezoidal block is used to squeeze the second trapezoidal block.

[0011] Further, the feeding assembly includes a connecting frame, a first feeding shell, a second feeding shell, a third feeding shell, a first driving part and a feeding disc. The connecting frame is fixedly connected to the workbench. The connecting frame is fixedly connected with the first feeding shell, the second feeding shell and the third feeding shell in sequence from bottom to top, and the three are in contact with each other. The first driving part is fixedly connected to the workbench. The power output end of the first driving part is fixedly connected with three feeding discs respectively rotating in the first feeding shell, the second feeding shell and the third feeding shell.

[0012] Further, the material feeding assembly further includes a sliding frame and a second driving member. An electric slider for driving the sliding frame to slide on the material feeding frame is slidably connected to the material feeding frame. The second driving members are fixedly connected to the sliding frame and are evenly distributed. The number of the second driving members corresponds to the number of the material feeding frames one by one. Uniformly distributed through holes are provided in the second material feeding shell, the third material feeding shell, and three adjacent material feeding trays. The through holes in the second material feeding shell, the third material feeding shell, and three adjacent material feeding trays are all used to guide the adjacent second driving members.

[0013] Further, the material feeding frame is fixedly connected to the adjacent third material feeding shell. The material feeding frame is provided with a clamping member and two limit pins. The clamping member is used to keep the outer tube stable during installation, and the two adjacent limit pins are used to support the bottom of the outer tube.

[0014] A production process of medical adhesive, based on the above-mentioned medical adhesive production device, the specific steps are as follows: Step 1: Assemble the handle to the rotating member; Step 2: The glass ampoule, the filter column, and the nozzle are respectively conveyed to the three material feeding trays by the first material feeding shell, the second material feeding shell, and the third material feeding shell, and the first driving member drives the three adjacent material feeding trays to rotate; Step 3: The material feeding frame conveys the outer tube, and the clamping member fixes the outer tube; Step 4: The telescopic end of the electric push rod extends out, so that the sliding plate drives the rotating member and the handle clamped by it to move synchronously through the first L-shaped frame; Step 5: When the handle moves with the rotating member to fit with the outer tube, when there are no defects on the handle and the outer tube, the handle is sleeved on the outer tube. When there are defects on the handle and the outer tube, the contact position between the handle and the outer tube is adjusted, and then the handle is sleeved on the outer tube. If the handle still cannot be sleeved on the outer tube after the adjustment, this handle and outer tube will no longer participate in the subsequent assembly process; Step 6: After the handle is sleeved on the outer tube, the sliding frame drives the glass ampoule, the filter column, and the nozzle to be connected to the outer tube in sequence through the second driving member, so as to complete the assembly of the handle, the outer tube, the glass ampoule, the filter column, and the nozzle.

[0015] Compared with the prior art, the present invention has the following advantages: To solve the problem of misalignment during assembly, the present invention introduces a real-time force monitoring mechanism during the assembly process and combines a handle swing and circumferential rotation adjustment strategy: when it is detected that the applied force exceeds a preset threshold, the automatic rotation mechanism of the handle is triggered to realign their positions, and then the rotation angle of the handle along the circumferential direction of the outer tube is adjusted. Subsequently, a squeezing force is continuously applied to the handle to align the handle and the round tube, further improving the alignment accuracy; If the extrusion force between the handle and the outer tube still continuously exceeds the safety threshold after the above adjustments, the system will pause the assembly operation at the current station and release the residual stress, and finally forcibly terminate the installation process to avoid irreversible damage caused by plastic deformation or structural overload of the handle and the outer tube.

Detailed implementation manners

[0018] The present invention will be further described in detail below in conjunction with the attached drawings and specific implementation manners, but the protection scope and application scope of the present invention are not limited.

[0019] In order to solve the problem that the alignment fails due to assembly defects between the handle and the outer tube, the present invention introduces force detection, handle swing, and circumferential rotation adjustment during the installation process. When the installation force exceeds the threshold, the handle will automatically rotate, aiming to adjust the relative position between the handle and the outer tube to realign the two. After the handle rotates, through circumferential rotation (i.e., rotation along the circumferential direction of the outer tube), the alignment accuracy of the two is further calibrated, thereby eliminating the alignment failure caused by assembly defects.

[0020] A medical adhesive production device, as Figures 1-8 shown, includes a workbench 1. Above the workbench 1, a plurality of uniformly distributed material conveying racks 2 are arranged. The workbench 1 is fixedly connected with a fixing rack 3. The fixing rack 3 is provided with an electric push rod 4. The workbench 1 is slidably connected with a sliding plate 5 fixedly connected to the telescopic end of the electric push rod 4. The sliding plate 5 is slidably connected with a plurality of uniformly distributed first L-shaped racks 6. The number of the first L-shaped racks 6 corresponds one-to-one to the number of the material conveying racks 2, and the first L-shaped racks 6 are located above adjacent material conveying racks 2. A first tension spring is fixedly connected between the first L-shaped racks 6 and the fixing rack 3. It further includes a second L-shaped rack 7, an arc-shaped block 8, a sliding frame 9, and a rotating part 10. The second L-shaped rack 7 slides along the first L-shaped rack 6. The arc-shaped block 8 is fixedly connected with the second L-shaped rack 7. The sliding frame 9 slides along the arc-shaped block 8 through an electric slider (here, the electric slider can be understood as an electric wheel for driving the sliding frame 9 to slide within the arc-shaped block 8). The rotating part 10 rotates along the sliding frame 9, and a torsion spring is arranged between the two. The arc-shaped block 8 is provided with a guiding component for driving the rotating part 10 to rotate. The workbench 1 is provided with a uniformly distributed material conveying component for conveying glass ampoules 103, filter columns 104, and nozzles 105. The number of the material conveying components corresponds one-to-one to the number of the material conveying racks 2.

[0021] In the above solution, a control terminal is provided on the front side of the workbench 1, and all electrical components in the device are electrically connected to the control terminal. Before using the device, it is first connected to an external manipulator or other conveying device (the number of external manipulators depends on the number of the first L-shaped frames 6, and the number of the first L-shaped frames 6 in the attached drawings is only for example, not limiting the specific number). The external manipulator controls the installation and disassembly of the handle 101. A conveying device for conveying the outer tube 102 onto the material conveying rack 2 is provided on the material conveying rack 2, and the conveying device can be a belt conveyor. When the handle 101 needs to be installed on the outer tube 102 (before this, a monitoring device can be installed on the fixing rack 3, and the monitoring device is used to monitor the alignment process of the handle 101 and the outer tube 102 in real time), the telescopic end of the electric push rod 4 extends out, so that the sliding plate 5 drives all the first L-shaped frames 6 to move downward. The first L-shaped frame 6 drives the handle 101 to move to contact with the outer tube 102 through the adjacent rotating member 10. When there are no defects on the handle 101 and the outer tube 102, the handle 101 is easily inserted onto the outer tube 102 along with the movement of the rotating member 10. When there are defects on the handle 101 and the outer tube 102, the handle 101 and the outer tube 102 cannot be aligned. At this time, the abnormality of the handle 101 and the outer tube 102 is detected by the monitoring device on the fixing rack 3, and at this time, the staff processes the abnormal position (the misaligned handle 101 and outer tube 102 can be manually taken out directly).

[0022] As Figure 6 and Figure 7 shown, a displacement sensor 11 is fixedly connected to the side of the first L-shaped frame 6 close to the second L-shaped frame 7, and the telescopic part of the displacement sensor 11 is fixedly connected to the second L-shaped frame 7.

[0023] In the above solution, the displacement sensor 11 is used to monitor the resistance when the handle 101 is sleeved on the outer tube 102. When the resistance increases, the telescopic part of the displacement sensor 11 retracts, so as to obtain the state of the handle 101 and the outer tube 102 during assembly (the monitoring of the handle 101 and the outer tube 102 can be realized by using the displacement sensor 11 instead of the above-mentioned monitoring device).

[0024] As Figures 8-10As shown in the figure, the guiding assembly includes a fixing plate 12, a first guiding rod 13, and a telescopic frame 14. The fixing plate 12 is fixedly connected to one side of the arc-shaped block 8 close to the second L-shaped frame 7. The fixing plate 12 is fixedly connected to the first guiding rod 13. The rotating member 10 is fixedly connected to the telescopic frame 14. The first guiding rod 13 is used to squeeze the telescopic frame 14. The guiding assembly further includes an arc-shaped slider 15 and a second guiding rod 16. The arc-shaped slider 15 slides along the sliding frame 9. The fixing plate 12 is fixedly connected to the second guiding rod 16. The arc-shaped slider 15 slides along the second guiding rod 16. The telescopic part of the telescopic frame 14 slides along the arc-shaped slider 15. The second guiding rod 16 is used to guide the telescopic part of the telescopic frame 14. A limiting assembly for restricting its position is provided on the first L-shaped frame 6. The rotating member 10 is composed of a hemispherical body, an arc-shaped shell, and a connecting plate. The hemispherical body and the arc-shaped shell are respectively fixed on both sides of the connecting plate. The hemispherical body on the rotating member 10 rotates along the sliding frame 9. The center of the circle where the arc-shaped edge of the symmetric cross-section of the arc-shaped slider 15 is located coincides with the center of the sphere of the hemispherical body on the rotating member 10. The center of the circle where the projection of the first guiding rod 13 on the horizontal plane is located coincides with the center of the sphere of the hemispherical body on the rotating member 10. The middle part of the second guiding rod 16 in the vertical direction and the middle part of the hemispherical body on the rotating member 10 in the vertical direction are located on the same horizontal plane. The distance between the second guiding rod 16 and the center of the sphere of the hemispherical body on the rotating member 10 gradually decreases from the side close to the fixing plate 12 to the side far from the fixing plate 12.

[0025] In the above solution, both the hemispherical body and the arc-shaped shell in the rotating member 10 are made of elastic materials to facilitate the fixation of the handle 101. The fixing plate 12 is used to fix the first guiding rod 13 and the second guiding rod 16. The first guiding rod 13 is composed of two arc-shaped rods and an arc-shaped inclined rod. The arc-shaped inclined rod is located between the two arc-shaped rods. The center of the circle where the projections of the two arc-shaped rods and the arc-shaped inclined rod on the horizontal plane are located coincides with the center of the sphere of the hemispherical body on the rotating member 10. The arc-shaped slider 15 slides back and forth along the sliding frame 9 to adapt to the bending degree of the second guiding rod 16. When the telescopic part of the telescopic frame 14 contacts the second guiding rod 16, the telescopic part of the telescopic frame 14 sliding along the second guiding rod 16 drives the rotating member 10 to rotate in the circumferential direction and gradually swing, so that the rotating member 10 gradually swings into a vertical state to realize the adjustment of the rotation angle of the rotating member 10 in the horizontal direction.

[0026] As Figures 5-7 shown in the figure, the limiting assembly includes a limiting frame 17, a first trapezoidal block 18, and a second trapezoidal block 19. The limiting frame 17 slides along the first L-shaped frame 6. A second tension spring is fixedly connected between the limiting frame 17 and the first L-shaped frame 6. The limiting frame 17 is used to limit the first L-shaped frame 6 on the sliding plate 5. The first trapezoidal block 18 is fixedly connected to the second L-shaped frame 7. The second trapezoidal block 19 is fixedly connected to the side of the limiting frame 17 close to the arc-shaped block 8. The first trapezoidal block 18 is used to squeeze the second trapezoidal block 19.

[0027] In the above solution, when the second trapezoidal block 19 is squeezed by the first trapezoidal block 18, the second trapezoidal block 19 drives the limit frame 17 to move backward, causing the upper side of the limit frame 17 to move backward along the sliding plate 5, enabling the first L-shaped frame 6 to slide up and down along the sliding plate 5, so that the sliding plate 5 does not drive the first L-shaped frame 6 to move synchronously during the downward movement.

[0028] As Figure 4 , Figure 11 , Figure 12 and Figure 14 shown, the material feeding assembly includes a connecting frame 20, a first feeding shell 21, a second feeding shell 22, a third feeding shell 23, a first driving member 24 and a feeding tray 25. The connecting frame 20 is fixedly connected to the workbench 1. The connecting frame 20 is fixedly connected with the first feeding shell 21, the second feeding shell 22 and the third feeding shell 23 in sequence from bottom to top, and the three are in contact with each other. The first driving member 24 is fixedly connected to the workbench 1, and the power output end of the first driving member 24 is fixedly connected with three feeding trays 25 that are respectively located in the first feeding shell 21, the second feeding shell 22 and the third feeding shell 23 and rotate therein.

[0029] In the above solution, a feeding device can be installed at the rear sides of the first feeding shell 21, the second feeding shell 22 and the third feeding shell 23 for respectively feeding the glass ampoules 103, the filter columns 104 and the nozzles 105 into the three. Through the rotation of the feeding tray 25, the glass ampoules 103, the filter columns 104 or the nozzles 105 are respectively fed to the front sides of the first feeding shell 21, the second feeding shell 22 and the third feeding shell 23 to facilitate the assembly of the glass ampoules 103, the filter columns 104 and the nozzles 105. The first driving member 24 is composed of a first electric turntable and a first connecting column. The power output end of the first driving member 24 is the first connecting column, and the first connecting column is fixedly connected with the adjacent three feeding trays 25.

[0030] As Figure 11 shown, the material feeding assembly further includes a sliding frame 26 and a second driving member 27. An electric slider for driving the sliding frame 26 to slide on the material feeding frame 2 is slidably connected to the material feeding frame 2. The sliding frame 26 is fixedly connected with uniformly distributed second driving members 27. The number of the second driving members 27 corresponds one-to-one to the number of the material feeding frames 2. Through holes are uniformly distributed in the second feeding shell 22, the third feeding shell 23 and the adjacent three feeding trays 25. The through holes in the second feeding shell 22, the third feeding shell 23 and the adjacent three feeding trays 25 are all used to guide the adjacent second driving members 27.

[0031] In the above solution, the second driving member 27 is composed of a second electric turntable and a second connecting column. The second connecting column is used to drive the corresponding nozzle 105 to rotate, so that the nozzle 105 can be screwed into the lower side of the corresponding outer tube 102. When the handle 101 and the outer tube 102 are defective and cannot be assembled, the first electric turntable of the first driving member 24 drives the first connecting column to rotate, so that the center of the second connecting column on the second driving member 27 coincides with the centers of the adjacent through holes on the adjacent three feeding trays 25, so that during subsequent assembly, the defective handle 101 and the glass ampoule 103, filter column 104 and nozzle 105 corresponding to the outer tube 102 do not participate in the subsequent assembly process.

[0032] As Figure 13 shown, the feeding rack 2 is fixedly connected to the adjacent third feeding shell 23. The feeding rack 2 is provided with a clamping member 28 and two limit pins 29. The clamping member 28 is used to keep the outer tube 102 stable during installation, and the adjacent two limit pins 29 are used to support the bottom of the outer tube 102.

[0033] In the above solution, the clamping member 28 is used to fix the outer tube 102 during the assembly process, and the two limit pins 29 are used to temporarily support the bottom of the outer tube 102 before assembly. The distance between the two limit pins 29 is greater than the diameter of the glass ampoule 103 and less than the diameter of the outer tube 102, so that the outer tube 102 will not fall down when it is located above the adjacent two limit pins 29, and the glass ampoule 103 can easily pass through the two limit pins 29 when moving upward.

[0034] Working principle: Before assembling the handle 101, outer tube 102, glass ampoule 103, filter column 104 and nozzle 105, an external manipulator first sends the handle 101 into the hemispherical body and the arc-shaped shell on the rotating member 10, so that the handle 101 is clamped into the hemispherical body and the arc-shaped shell to fix the handle 101. Subsequently, the feeding device sends the glass ampoule 103, filter column 104 and nozzle 105 into the first feeding shell 21, the second feeding shell 22 and the third feeding shell 23 respectively, and then the first feeding shell 21, the second feeding shell 22 and the third feeding shell 23 slide into the three feeding trays 25 respectively. At this time, the first driving member 24 drives the adjacent three feeding trays 25 to rotate, so that the three feeding trays 25 drive the glass ampoule 103, filter column 104 and nozzle 105 to rotate to the position shown in Figure 10 (during this process, the conveying device connected to the feeding rack 2 conveys the outer tube 102 to the upper side of the adjacent two limit pins 29, and at this time the clamping member 28 fixes the outer tube 102). Through the above operations, the assembly actions of the handle 101, outer tube 102, glass ampoule 103, filter column 104 and nozzle 105 before assembly are completed.

[0035] After completing the assembly actions of the handle 101, the outer tube 102, the glass ampoule 103, the filter column 104, and the nozzle 105 before assembly, the staff controls the telescopic end of the electric push rod 4 to extend through the control terminal. The telescopic end of the electric push rod 4 drives the first L-shaped frame 6 to move downward through the sliding plate 5 and all the limiting frames 17 (the first L-shaped frame 6 pulls the adjacent first tension spring during the process of sliding with the sliding plate 5). The first L-shaped frame 6 drives the sliding frame 9, the rotating member 10, and the handle 101 clamped by it to move downward synchronously through the second L-shaped frame 7.

[0036] When the rotating member 10 drives the handle 101 to move into contact with the outer tube 102 and there are no defects between them, the handle 101 is slowly sleeved onto the outer tube 102 (at this time, the telescopic part of the displacement sensor 11 will not be squeezed), thereby completing the assembly of the handle 101 and the outer tube 102.

[0037] When there are defects in the handle 101 and the outer tube 102, the handle 101 cannot be sleeved onto the outer tube 102. At this time, there is resistance between them, causing the second L-shaped frame 7 to slide relative to the first L-shaped frame 6 and squeezing the telescopic part of the displacement sensor 11. The displacement sensor 11 transmits the electrical signal to the electric slider on the sliding frame 9 through the control terminal, causing the electric slider to drive the sliding frame 9 to move to the right along the arc-shaped block 8. During the movement of the sliding frame 9, the handle 101 is driven to rotate by the rotating member 10. The rotating member 10 drives the telescopic frame 14 to slide along the first guiding rod 13. Along with the rotation of the rotating member 10, the telescopic part of the telescopic frame 14 is squeezed by the arc-shaped inclined rod in the first guiding rod 13, so as to slide downward along the arc-shaped slider 15. Now, taking Figure 7 the front view as an example, the rotating member 10 is rotated clockwise along the sliding frame 9 (the torsion spring is gradually tightened during the rotation of the lower side of the rotating member 10), and the position of the handle 101 aligned with the outer tube 102 is adjusted.

[0038] As the telescopic frame 14 swings downward, when the telescopic part of the telescopic frame 14 contacts the second guiding rod 16, along with the rotation of the rotating member 10, the telescopic part of the telescopic frame 14 and the arc-shaped slider 15 are guided by the second guiding rod 16. The telescopic part of the telescopic frame 14 gradually contracts, and the arc-shaped slider 15 moves toward the side close to the handle 101, causing the rotating member 10 and the handle 101 to rotate along the circumferential direction of the outer tube 102, and making the rotating member 10 gradually return to the vertical state, further adjusting the alignment accuracy, simulating the operation of manually rotating the pen cap to cover the pen cap on the pen.

[0039] After the handle 101 rotates to be sleeved onto the outer tube 102, the electric slider on the sliding frame 9 drives the rotating member 10 and its components to rotate until the telescopic part of the telescopic frame 14 no longer contacts the second guiding rod 16, and the telescopic part of the telescopic frame 14 also no longer contacts the first guiding rod 13. Under the action of the torsion spring on the sliding frame 9, the rotating member 10 rotates back to its original position.

[0040] After the above calibration, when the handle 101 and the outer tube 102 are still not assembled, the second L-shaped frame 7 continues to move upward. The second L-shaped frame 7 drives the first trapezoidal block 18 to squeeze the second trapezoidal block 19, so that the second trapezoidal block 19 drives the limit frame 17 to move away from the first L-shaped frame 6 and stretch the second spring. During the movement of the limit frame 17, it disengages from the contact with the sliding plate 5. Under the action of the first pulling spring on the first L-shaped frame 6, the first L-shaped frame 6 drives the parts on it and the handle 101 to move upward rapidly through the second L-shaped frame 7, so that the handle 101 no longer participates in the subsequent assembly process (after the first L-shaped frame 6 moves upward, the telescopic part of the displacement sensor 11 extends, and the limit frame 17 moves and resets under the action of the second pulling spring).

[0041] When the handle 101 cannot be assembled with the outer tube 102, the first electric turntable in the first driving member 24 corresponding to the two drives the first connecting column to rotate, so that the center of the second connecting column of the second driving member 27 coincides with the centers of the adjacent through holes on the adjacent three feeding disks 25, so that the defective handle 101 and the corresponding glass ampoule 103, filter column 104 and nozzle 105 of the outer tube 102 do not participate in the subsequent assembly process.

[0042] After the handle 101 is sleeved on the outer tube 102, the electric slider on the sliding frame 26 drives the sliding frame 26 and all the second driving members 27 to move upward. When the second connecting column in the second driving member 27 contacts the nozzle 105, the second connecting column in the second driving member 27 drives the filter column 104 and the glass ampoule 103 to move upward through the nozzle 105, so that the glass ampoule 103 and the filter column 104 are successively inserted into the outer tube 102. When the nozzle 105 moves to contact the lower side of the outer tube 102 on its upper side, the sliding frame 26 stops moving. At this time, the electric turntable on the second driving member 27 controls the second connecting column to rotate, and the second connecting column drives the nozzle 105 to rotate, so that the nozzle 105 is screwed into the outer tube 102, thus completing the assembly of the handle 101, the outer tube 102, the glass ampoule 103, the filter column 104 and the nozzle 105. After the assembly of the handle 101, the outer tube 102, the glass ampoule 103, the filter column 104 and the nozzle 105 is completed, the clamping member 28 no longer fixes the outer tube 102.

[0043] When the assembly work is completed, the electric slider on the sliding frame 26 drives the sliding frame 26 and all the second driving members 27 to reset and move to Figure 10 the state in, and then the electric push rod 4 drives the parts of its telescopic part to reset and move to Figure 4After reaching the state in , the manipulator takes out the assembled handle 101, outer tube 102, glass ampoule 103, filter column 104 and nozzle 105 or the defective handle 101 and outer tube 102. Subsequently, the staff manipulates the parts on the rotating member 10 to reset (the prerequisite for this action is that there is a rotating member 10 corresponding to the defective handle 101 and outer tube 102). The staff first manually pulls the limit frame 17 to the side away from the first L-shaped frame 6, so that the limit frame 17 pulls the second tension spring and moves to insert into the sliding plate 5. After the upper side of the limit frame 17 can be inserted into the sliding plate 5, the staff releases the limit frame 17, and the limit frame 17 is inserted into the sliding plate 5 under the action of the second tension spring. Subsequently, the staff manipulates the electric slider on the sliding frame 9 through the control terminal to drive the sliding frame 9 to reset and rotate. During this process, the staff calibrates the arc-shaped slider 15 with the second guide rod 16, so that the arc-shaped slider 15 slides along the second guide rod 16 during reset. Subsequently, the telescopic frame 14 is calibrated with the first guide rod 13, so that the telescopic part of the telescopic frame 14 slides along the lower side of the first guide rod 13 during reset. The above parts move to Figure 8 After reaching the state in , the reset action of the above parts is completed.

When there are defects in the handle 101 and the outer tube 102, the contact position between the handle 101 and the outer tube 102 is adjusted, and then the handle 101 is sleeved on the outer tube 102. If, after the adjustment is completed, the handle 101 still cannot be sleeved on the outer tube 102, this handle 101 and outer tube 102 will no longer participate in the subsequent assembly process; Step 6: After the handle 101 is sleeved on the outer tube 102, the sliding frame 26 drives the glass ampoule 103, the filter column 104 and the nozzle 105 to be connected to the outer tube 102 in sequence through the second driving member 27, so as to complete the assembly of the handle 101, the outer tube 102, the glass ampoule 103, the filter column 104 and the nozzle 105.
