Description

Technical Field

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

[0002] Medical adhesives are a special type of material designed specifically for medical applications. They achieve adhesion and repair between human tissues and devices through chemical or biological effects. The production process includes the following steps:

[0003] Pour medical adhesive into glass ampoule and seal it by melting;

[0004] Place the sealed ampoule into the outer tube through the installation equipment;

[0005] Connect the handle to one end of the outer tube and install the filter column and nozzle in sequence on the other end;

[0006] Finally, the components are assembled in the order of "handle-outer tube-glass ampoule-filter column-nozzle".

[0007] However, the connection between the handle and the outer tube is a critical step. Since the outer tube is usually made of soft materials (such as rubber or soft plastic) to adapt to the deformation of the handle when it is squeezed, this design causes new problems in actual operation: if the handle and the outer tube have defects, such as if either the handle or the outer tube is deformed, it will cause the handle and the outer tube to be misaligned. At this time, if the handle and the outer tube are assembled, the outer tube will be prone to plastic deformation due to the soft material and uneven force, and the handle will break due to excessive squeezing. The above problems mainly arise from slight alignment deviations when the two are assembled. Summary of the Invention

[0014] Furthermore, the limit assembly includes a limit frame, a first trapezoidal block and a second trapezoidal block, the limit frame slides along the first L-shaped frame, a second tension spring is fixed between the limit frame and the first L-shaped frame, the limit frame is used to limit the first L-shaped frame to the sliding plate, the first trapezoidal block is fixed to the second L-shaped frame, the second trapezoidal block is fixed to the side of the limit frame close to the arc block, and the first trapezoidal block is used to squeeze the second trapezoidal block.

[0015] Furthermore, the feeding assembly includes a connecting frame, a first feeding shell, a second feeding shell, a third feeding shell, a first driving member and a feeding tray. The connecting frame is fixedly connected to the workbench. The connecting frame is fixedly connected to the first feeding shell, the second feeding shell and the third feeding shell in order from bottom to top, and the three are in contact with each other. The first driving member is fixedly connected to the workbench. The power output end of the first driving member is fixedly connected to three feeding trays that rotate in the first feeding shell, the second feeding shell and the third feeding shell respectively.

[0016] Furthermore, the feeding assembly also includes a sliding frame and a second driving member, the feeding frame is slidably connected to an electric slider for driving the sliding frame to slide on the feeding frame, the sliding frame is fixed with evenly distributed second driving members, the number of the second driving members corresponds one to one to the number of the feeding frames, and the second feeding shell, the third feeding shell and the three adjacent feeding trays are all provided with evenly distributed through holes, and the through holes in the second feeding shell, the third feeding shell and the three adjacent feeding trays are all used to guide adjacent second driving members.

DETAILED DESCRIPTION

[0042] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0043] In order to solve the problem of alignment failure between the handle and the outer tube due to assembly defects, the present invention introduces force detection and handle swinging, as well as circumferential rotation adjustment during the installation process. When the installation force exceeds a threshold, the handle will automatically rotate. The purpose is to adjust the relative position of the handle and the outer tube so that the two are realigned. After the handle rotates, the circumferential rotation (i.e., rotation along the circumferential direction of the outer tube) is used to further calibrate the alignment accuracy of the two, thereby eliminating the alignment failure caused by assembly defects.

[0044] A medical adhesive production device, such as Figures 1-8 As shown, it includes a workbench 1, a plurality of evenly distributed feed racks 2 are arranged above the workbench 1, the workbench 1 is fixedly connected to a fixed frame 3, the fixed frame 3 is provided with an electric push rod 4, the workbench 1 is slidably connected to a sliding plate 5 fixed to the telescopic end of the electric push rod 4, the sliding plate 5 is slidably connected to a plurality of evenly distributed first L-shaped frames 6, the number of the first L-shaped frames 6 corresponds to the number of the feed racks 2, and the first L-shaped frames 6 are located above the adjacent feed racks 2, a first tension spring is fixed between the first L-shaped frame 6 and the fixed frame 3, and further includes a second L-shaped frame 7, an arc block 8, a sliding frame 9 and a rotating member 10. The second L-shaped frame 7 slides along the first L-shaped frame 6, the arc block 8 is fixed to the second L-shaped frame 7, and the sliding frame 9 slides along the arc block 8 through an electric slider (the electric slider here can be understood as an electric wheel, which is used to drive the sliding frame 9 to slide in the arc block 8), and the rotating member 10 rotates along the sliding frame 9, and a torsion spring is provided between the two. A guide component for driving the rotating member 10 to rotate is provided on the arc block 8, and a uniformly distributed feeding component for conveying glass ampoules 103, filter columns 104 and nozzles 105 is provided on the workbench 1. The number of feeding components corresponds to the number of feeding frames 2.

[0045] In the above scheme, 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 first L-shaped frames 6, and the number of first L-shaped frames 6 in the accompanying drawings is only an example and does not limit the specific number), so that the external manipulator controls the installation and removal of the handle 101. A conveying device for conveying the outer tube 102 to the conveying frame 2 is provided on the conveying frame 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 frame 3, and the monitoring device is used to monitor the handle 101 in real time and the outer tube 102), the telescopic end of the electric push rod 4 extends, causing the sliding plate 5 to drive all the first L-shaped frames 6 to move downward, and the first L-shaped frame 6 drives the handle 101 to move to contact the outer tube 102 through the adjacent rotating member 10. When the handle 101 and the outer tube 102 are flawless, the handle 101 is easily inserted into the outer tube 102 as the rotating member 10 moves. When the handle 101 and the outer tube 102 have defects, the handle 101 and the outer tube 102 cannot be aligned. At this time, the monitoring equipment on the fixed frame 3 detects the abnormality of the handle 101 and the outer tube 102, and the staff will handle the abnormal position (the handle 101 and the outer tube 102 that cannot be aligned can be manually removed directly).

[0046] like Figure 6 and Figure 7As shown, a displacement sensor 11 is fixedly connected to one side of the first L-shaped frame 6 close to the second L-shaped frame 7 , and a telescopic portion of the displacement sensor 11 is fixedly connected to the second L-shaped frame 7 .

[0047] In the above scheme, the displacement sensor 11 is used to monitor the resistance when the handle 101 is put on the outer tube 102. When the resistance increases, the telescopic part of the displacement sensor 11 retracts, thereby obtaining the status of the handle 101 and the outer tube 102 during assembly (the displacement sensor 11 can be used instead of the above-mentioned monitoring equipment to realize the monitoring of the handle 101 and the outer tube 102).

[0048] like Figures 8-10 As shown, the guide assembly includes a fixed plate 12, a first guide rod 13 and a telescopic frame 14, the fixed plate 12 is fixed to the side of the arc block 8 close to the second L-shaped frame 7, the fixed plate 12 is fixed to the first guide rod 13, the rotating member 10 is fixed to the telescopic frame 14, the first guide rod 13 is used to squeeze the telescopic frame 14, the guide assembly also includes an arc-shaped slider 15 and a second guide rod 16, the arc-shaped slider 15 slides along the sliding frame 9, the fixed plate 12 is fixed to the second guide rod 16, the arc-shaped slider 15 slides along the second guide rod 16, the telescopic portion of the telescopic frame 14 slides along the arc-shaped slider 15, the second guide rod 16 is used to guide the telescopic portion of the telescopic frame 14, and the first L-shaped frame 6 is provided with a The limiting assembly, the rotating part 10 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 10 rotates along the sliding frame 9. The center of the circle where the arc edge of the symmetrical cross-section of the arc-shaped slider 15 is located coincides with the center of the hemisphere on the rotating part 10. The center of the circle where the projection of the first guide rod 13 on the horizontal plane is located coincides with the center of the hemisphere on the rotating part 10. The middle part of the second guide rod 16 in the vertical direction and the middle part of the hemisphere on the rotating part 10 in the vertical direction are located in the same horizontal plane. The distance between the second guide rod 16 and the center of the hemisphere on the rotating part 10 gradually decreases from the side close to the fixed plate 12 to the side away from the fixed plate 12.

[0049] In the above scheme, the hemisphere and the arc shell in the rotating member 10 are both made of elastic material to facilitate fixing the handle 101. The fixing plate 12 is used to fix the first guide rod 13 and the second guide rod 16. The first guide rod 13 is composed of two arc rods and an arc oblique rod. The arc oblique rod is located between the two arc rods, and the center of the circle where the two arc rods and the arc oblique rod are projected on the horizontal plane coincides with the center of the hemisphere of the upper part of the rotating member 10. The arc slider 15 slides back and forth along the sliding frame 9 to adapt to the bending degree of the second guide rod 16. When the telescopic part of the telescopic frame 14 contacts the second guide rod 16, the telescopic part of the telescopic frame 14 slides along the second guide rod 16, driving the rotating member 10 to rotate in the circumferential direction and gradually swing, so that the rotating member 10 gradually swings to a vertical shape to achieve adjustment of the horizontal rotation angle of the rotating member 10.

[0050] like Figure 5-Figure 7 As shown, 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 fixed 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 to the sliding plate 5. The first trapezoidal block 18 is fixed to the second L-shaped frame 7. The second trapezoidal block 19 is fixed to the side of the limiting frame 17 close to the arc block 8. The first trapezoidal block 18 is used to squeeze the second trapezoidal block 19.

[0051] In the above scheme, when the second trapezoidal block 19 is squeezed by the first trapezoidal block 18, the second trapezoidal block 19 drives the limiting frame 17 to move backward, so that the upper side of the limiting frame 17 moves backward along the sliding plate 5, so that the first L-shaped frame 6 can slide up and down along the sliding plate 5, so that the sliding plate 5 no longer drives the first L-shaped frame 6 to move synchronously during the downward movement.

[0052] like Figure 4 、 Figure 11 、 Figure 12 and Figure 14 As shown, the 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 order 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. The power output end of the first driving member 24 is fixedly connected with three feeding trays 25 that rotate in the first feeding shell 21, the second feeding shell 22 and the third feeding shell 23 respectively.

[0053] In the above scheme, a feeding device can be installed on the rear side of the first feeding shell 21, the second feeding shell 22 and the third feeding shell 23, which is used to feed the glass ampoule 103, the filter column 104 and the nozzle 105 into the three respectively. Through the rotation of the feeding tray 25, the glass ampoule 103, the filter column 104 or the nozzle 105 are respectively fed into the front side of the first feeding shell 21, the second feeding shell 22 and the third feeding shell 23 to facilitate the assembly of the glass ampoule 103, the filter column 104 and the nozzle 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 to the three adjacent feeding trays 25.

[0054] like Figure 11As shown, the feeding assembly also includes a sliding frame 26 and a second driving member 27. The feeding frame 2 is slidably connected to an electric slider for driving the sliding frame 26 to slide on the feeding frame 2. The sliding frame 26 is fixed with evenly distributed second driving members 27. The number of second driving members 27 corresponds to the number of feeding frames 2. Evenly distributed through holes are provided in the second feeding shell 22, the third feeding shell 23 and the three adjacent feeding trays 25. The through holes in the second feeding shell 22, the third feeding shell 23 and the three adjacent feeding trays 25 are all used to guide the adjacent second driving members 27.

[0055] In the above scheme, 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 center of the adjacent through holes on the three adjacent feed trays 25. During subsequent assembly, the glass ampoule 103, filter column 104 and nozzle 105 corresponding to the defective handle 101 and outer tube 102 do not participate in the subsequent assembly process.

[0056] like Figure 13 As shown, the feed frame 2 is fixedly connected to the adjacent third feed shell 23 , and the feed frame 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 two adjacent limit pins 29 are used to support the bottom of the outer tube 102 .

[0057] In the above scheme, 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 smaller than the diameter of the outer tube 102, so as to prevent the outer tube 102 from falling down when it is located on the upper side of the two adjacent limit pins 29, and to enable the glass ampoule 103 to easily pass through the two limit pins 29 when moving upward.

[0058] Working principle: Before assembling the handle 101, outer tube 102, glass ampoule 103, filter column 104 and nozzle 105, the external manipulator first feeds the handle 101 into the hemisphere and arc shell on the rotating part 10, so that the handle 101 is stuck in the hemisphere and arc shell to fix the handle 101, and then the feeding equipment feeds 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, and then the first driving member 24 drives the three adjacent 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 where Figure 10 The outer tube 102 is in the state of (during this process, the conveying equipment connected to the conveying rack 2 conveys the outer tube 102 to the upper side of the two adjacent limit pins 29, and the outer tube 102 is then fixed by the clamping member 28). The above operation completes the assembly action of the handle 101, outer tube 102, glass ampoule 103, filter column 104 and nozzle 105 before assembly.

[0059] After completing the assembly of the handle 101, outer tube 102, glass ampoule 103, filter column 104 and 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 limit frames 17 (the first L-shaped frame 6 pulls the adjacent first tension spring during the sliding process of the sliding plate 5). The first L-shaped frame 6 drives the sliding frame 9, the rotating part 10 and the handle 101 clamped by it to move downward synchronously through the second L-shaped frame 7.

[0060] When the rotating member 10 drives the handle 101 to move to contact the outer tube 102 and there are no defects between the two, the handle 101 is slowly put 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.

[0061] When defects appear on the handle 101 and the outer tube 102, the handle 101 cannot be put on the outer tube 102. At that time, resistance occurs between the two, causing the second L-shaped frame 7 and the first L-shaped frame 6 to slide relative to each other, and the telescopic part of the displacement sensor 11 is squeezed. The displacement sensor 11 transmits an electrical signal to the electric slider on the sliding frame 9 via the control terminal, so that the electric slider drives the sliding frame 9 to move right along the arc block 8. During the movement of the sliding frame 9, the handle 101 is rotated by the rotating member 10, and the rotating member 10 drives the telescopic frame 14 to slide along the first guide rod 13. As the rotating member 10 rotates, the telescopic part of the telescopic frame 14 is squeezed by the arc-shaped oblique rod inside the first guide rod 13, thereby sliding downward along the arc slider 15. Figure 7As an example, the rotating member 10 rotates 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.

[0062] As the telescopic frame 14 swings downward, when the telescopic portion of the telescopic frame 14 contacts the second guide rod 16, along with the rotation of the rotating member 10, the telescopic portion of the telescopic frame 14 and the arc-shaped slider 15 are guided by the second guide rod 16, the telescopic portion of the telescopic frame 14 gradually contracts, and the arc-shaped slider 15 moves to the side close to the handle 101, so that the rotating member 10 and the handle 101 rotate along the circumferential direction of the outer tube 102, and the rotating member 10 gradually returns to the vertical state, further adjusting the alignment accuracy, simulating the operation of manually turning the pen cap to cover the pen cap on the pen.

[0063] After the handle 101 is rotated to the point where it can be sleeved onto the outer tube 102, the electric slider on the sliding frame 9 drives the rotating member 10 and the parts thereon to rotate until the telescopic portion of the telescopic frame 14 no longer contacts the second guide rod 16, and the telescopic portion of the telescopic frame 14 no longer contacts the first guide rod 13. Under the action of the torsion spring on the sliding frame 9, the rotating member 10 is reset and rotated.

[0064] After the above calibration, when the handle 101 and the outer tube 102 are not yet assembled, the second L-shaped frame 7 continues to move upward, and 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 to the side away from the first L-shaped frame 6 and stretches the second spring. During the movement of the limit frame 17, it breaks away from the contact with the sliding plate 5. Under the action of the first tension spring on the first L-shaped frame 6, the first L-shaped frame 6 drives the parts thereon 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 tension spring).

[0065] 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 center of the adjacent through holes on the three adjacent feeding trays 25, so that the glass ampoule 103, filter column 104 and nozzle 105 corresponding to the defective handle 101 and outer tube 102 do not participate in the subsequent assembly process.

[0066] When the handle 101 is put 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 inserted into the outer tube 102 one by one. When the nozzle 105 moves to the point where its upper side contacts the lower side of the outer tube 102, , the sliding frame 26 stops moving, and the electric turntable on the second driving member 27 controls the second connecting column to rotate. The second connecting column drives the nozzle 105 to rotate, so that the nozzle 105 is screwed into the outer tube 102, thereby completing the assembly of the handle 101, outer tube 102, glass ampoule 103, filter column 104 and nozzle 105. After completing the assembly of the handle 101, outer tube 102, glass ampoule 103, filter column 104 and nozzle 105, the clamping member 28 no longer fixes the outer tube 102.

[0067] When the assembly 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 the Figure 10 The electric push rod 4 then drives the parts of the telescopic part to reset and move to Figure 4 After the state is in the middle, the robot will remove 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, and then the staff will manipulate the parts on the rotating part 10 to reset (the premise of this action is that the rotating part 10 corresponding to the defective handle 101 and outer tube 102 exists). The staff will first manually pull 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. The upper side of the limit frame 17 can After the sliding plate 5 is 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. Then the staff controls 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 slider 15 with the second guide rod 16 so that the arc slider 15 slides along the second guide rod 16 when resetting. Then, the telescopic frame 14 is calibrated with the first guide rod 13 so that the telescopic portion of the telescopic frame 14 slides along the lower side of the first guide rod 13 when resetting. The above parts move to Figure 8 After entering the state, the reset action of the above parts is completed.

The first driving member 24 drives the three adjacent feeding trays 25 to rotate;

[0071] Step 3: The conveying frame 2 conveys the outer tube 102, and the clamping member 28 fixes the outer tube 102;

[0072] Step 4: The telescopic end of the electric push rod 4 extends, so that the sliding plate 5 drives the rotating member 10 and the handle 101 clamped therein to move synchronously through the first L-shaped frame 6;

[0073] Step 5: After the handle 101 moves along with the rotating member 10 to fit with the outer tube 102, if there are no defects on the handle 101 and the outer tube 102, the handle 101 is put on the outer tube 102. If there are defects on the handle 101 and the outer tube 102, adjust the contact position of the handle 101 and the outer tube 102, and then put the handle 101 on the outer tube 102. If the handle 101 still cannot be put on the outer tube 102 after the adjustment, the handle 101 and the outer tube 102 will no longer participate in the subsequent assembly process;

[0074] Step 6: After the handle 101 is put 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, thereby completing the assembly of the handle 101, the outer tube 102, the glass ampoule 103, the filter column 104 and the nozzle 105.
