[0033] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0034] Example 1: This application discloses an automated production line for EVA female external urinary catheters, such as... Figure 1As shown, the machine includes a frame 1, on which are sequentially arranged a tube cutting and feeding mechanism 101, a drain connector feeding mechanism 102, an EVA bag body film feeding rack 103, an EVA bag body film punching mechanism 104, a water storage net cotton feeding mechanism 105, a catheter welding mechanism 106; an EVA bag body bottom film feeding rack 107, a CCD product inspection mechanism 108, a blister packaging feeding rack 109, a blister forming mechanism 110, a UDI inkjet coding mechanism 111, a UDI code reading and inspection mechanism 112, and a CCD packaging appearance inspection mechanism 113. The catheter feeding mechanism 101 is used to heat and cut the catheter; the drain connector feeding mechanism 102 is used to install the connector onto the catheter; the EVA bag body mask feeding rack 103 is used to place the EVA bag body mask; the EVA bag body mask punching mechanism 104 is used to punch holes in the EVA bag body mask; the water storage mesh feeding mechanism 105 is used to place the water storage mesh on the bottom film; the catheter welding mechanism 106 is used to weld the EVA mask and the EVA bottom film; and the EVA bag bottom... The film feeding rack 107 is used to place the bottom film of the EVA bag, the CCD product inspection mechanism 108 is used to inspect the catheter, the blister packaging feeding rack 109 is used to place the packaging bag, the blister forming mechanism 110 is used to install the catheter into the packaging bag, the UDI coding mechanism 111 is used to code the packaging bag, the UDI code reading and inspection mechanism 112 is used to inspect the packaged bag after coding, and the CCD packaging appearance inspection mechanism 113 is used to inspect the packaged bag after coding.

[0035] The implementation principle of the automated production line for EVA female external urinary catheters in this application embodiment is as follows: In actual operation, the operator places the coiled tubing, EVA bag face film, bottom film, and blister packaging materials in a fixed position. The catheter, after passing through the tube cutting and feeding mechanism 101, is heated to straighten any bent or deformed sections. Then, the catheter is cut at an angle, and the drain connector is inserted into the catheter via the drain connector feeding mechanism 102. The face film is perforated by the EVA bag face film punching mechanism 104. The catheter and water-retaining mesh are placed on the bottom film, and the face film covers the bottom film containing the catheter and water-retaining mesh. The bag is then welded at the catheter welding mechanism 106, and the catheter is then heat-sealed at the edges. The conveyor belt transports the product to the CCD product inspection mechanism 108 for visual inspection, and any defective products are identified. The vacuum forming mechanism 110 operates to package the product. The UDI coding mechanism 111 prints the code, and the UDI code reading and detection mechanism 112 detects and rejects unqualified products. Subsequently, the CCD packaging appearance inspection mechanism 113 detects and removes unqualified products, thus completing the entire product production and packaging process. No manual operation is required, which reduces the labor intensity of operators and improves the production efficiency of the product.

[0036] Example 2: like Figure 2As shown, this embodiment of the application, based on Embodiment 1, further includes an impregnation mechanism 2. The impregnation mechanism 2 is located between the tube cutting and feeding mechanism 101 and the drainage feeding mechanism. The impregnation mechanism 2 includes an impregnation frame 21, an impregnation box 22, an impregnation assembly 3, a feeding assembly 4, and a discharging assembly 5. The impregnation frame 21 is mounted on the frame 1, and the impregnation box 22 is fixedly mounted inside the impregnation frame 21. The impregnation box 22 is used to hold the adhesive solution. The impregnation assembly 3 is located above the impregnation box 22, the feeding assembly 4 is located on one side of the impregnation assembly 3, and the discharging assembly 5 is located on the other side of the impregnation assembly 3. The impregnation assembly 3 is used to move the urinary catheter into the impregnation box 22 for impregnation, the feeding assembly 4 is used to move the unelectrified urinary catheter onto the impregnation assembly 3, and the discharging assembly 5 is used to remove the impregnated urinary catheter from the impregnation assembly 3. After the catheter passes through the catheter cutting and feeding mechanism 101, the catheter needs to be impregnated with glue to improve the surface hydrophilicity of the catheter and reduce the possibility of the catheter surface causing damage to human soft tissue.

[0037] like Figure 2 and 3 As shown, the impregnation assembly 3 includes a drive box 31, an mounting box 32, and a mounting post 33. The drive box 31 and the impregnation frame 21 slide relative to each other. The drive box 31 reciprocates along the direction of catheter travel. An electric slide 34 for controlling the movement of the drive box 31 is fixedly mounted on the impregnation frame 21. The mounting box 32 and the drive box 31 are rotatably connected. The drive box 31 is provided with a rotating assembly 6 for controlling the rotation of the mounting box 32. The rotating assembly 6 includes a first bevel gear 61, a second bevel gear 62, and a first motor 63. Both the first bevel gear 61 and the second bevel gear 62 are located inside the drive box 31. The rotating shaft 321 of the first bevel gear 61 and the first motor 63 is fixedly connected. The first motor 63 is fixedly mounted on the drive box 31. A rotating rod is fixedly connected to one end of the mounting box 32. The end of the rotating rod away from the mounting box 32 extends into the drive box 31 and is coaxially fixedly connected to the second bevel gear 62. The first bevel gear 61 and the second bevel gear 62 mesh. The mounting post 33 is used for the catheter. One end of the mounting post 33 is located inside the mounting box 32, and the other end extends out of the mounting box 32. The mounting post 33 and the mounting box 32 are rotatably connected. A second motor 35 is fixedly installed inside the mounting box 32. A worm gear 351 is fixedly connected to the rotating shaft 321 of the second motor 35. A worm wheel 331 that cooperates with the worm gear 351 is coaxially fixedly connected to the mounting post 33.

[0038] When the catheter is fitted onto the mounting post 33, the operator can drive the first motor 63, causing its rotating shaft 321 to rotate the first bevel gear 61. The rotation of the first bevel gear 61 then drives the second bevel gear 62, which in turn rotates the rotating rod and the mounting box 32. The rotation of the mounting box 32 then rotates the mounting post 33, thus rotating the catheter on the mounting post 33 into the impregnation box 22 for impregnation. When the catheter is impregnated in the impregnation box 22, the operator drives the second motor 35, causing its rotating shaft 321 to rotate the worm gear 351. The worm wheel 331 then rotates, causing the mounting post 33 to rotate the catheter, improving the impregnation effect.

[0039] like Figure 2 and 4 As shown, the feeding assembly 4 includes a feeding frame 41, a feeding pressure plate 42, and a feeding slide plate 43. The feeding frame 41 and the dip frame 21 are slidably connected. A slider is fixedly connected to the feeding frame 41. The dip frame 21 has a groove for the slider of the feeding frame 41 to slide. The feeding frame 41 slides closer to or further away from the mounting box 32. The feeding pressure plate 42 and the feeding frame 41 are slidably connected in the vertical direction. A slider is fixedly connected to the feeding pressure plate 42. The feeding frame 41 has a groove for the slider of the feeding pressure plate 42 to slide. A screw is threadedly connected to the slider of the feeding pressure plate 42, and a motor controls the rotation of the screw, thereby realizing the reciprocating movement of the feeding pressure plate 42 in the vertical direction. The feeding slide plate 43 is used to place the urinary catheter. The feeding slide plate 43 and the feeding rack 41 are slidably connected in the horizontal direction. A slider is fixedly connected to the bottom of the feeding slide plate 43. The feeding rack 41 has a groove for the slider of the feeding slide plate 43 to slide, a screw threadedly connected to the slider of the feeding slide plate 43, and a motor that controls the rotation of the screw, thereby realizing the reciprocating movement of the feeding slide plate 43 in the horizontal direction. When the urinary catheter needs to be impregnated with glue, the feeding slide plate 43 is moved away from the feeding rack 41 and slides. Then, the urinary catheter is moved onto the feeding slide plate 43 by a robotic arm. After that, the feeding slide plate 43 is reset into the feeding rack 41. The feeding pressure plate 42 moves toward the feeding slide plate 43 and abuts against the urinary catheter on the feeding pressure plate 42, so that the urinary catheter is fixed on the feeding slide plate 43. This makes it easy for the feeding rack 41 to move the urinary catheter toward the mounting box 32 and put the urinary catheter onto the mounting post 33, which facilitates the impregnation of the urinary catheter.

[0040] like Figure 2 and 5As shown, the unloading assembly 5 includes an unloading frame 51, an unloading pressure plate 52, and an unloading slide plate 53. The unloading frame 51 and the dip frame 21 are slidably connected. A slider is fixedly connected to the unloading frame 51. A groove is provided on the dip frame 21 for the slider of the unloading frame 51 to slide. The unloading frame 51 slides close to or against the mounting box 32. The unloading pressure plate 52 and the unloading frame 51 are slidably connected in the vertical direction. A slider is fixedly connected to the unloading pressure plate 52. A groove is provided on the unloading frame 51 for the slider of the unloading pressure plate 52 to slide. A screw is threadedly connected to the slider of the unloading pressure plate 52, and a motor controls the rotation of the screw, thereby realizing the reciprocating movement of the unloading pressure plate 52 in the vertical direction. The feeding slide plate 53 is used to place the catheter. The feeding slide plate 53 and the feeding frame 51 are slidably connected in the horizontal direction. A slider is fixedly connected to the bottom of the feeding slide plate 53. The feeding frame 51 has a groove for the slider of the feeding slide plate 53 to slide, a screw threadedly connected to the slider of the feeding slide plate 53, and a motor that controls the rotation of the screw, thereby realizing the reciprocating movement of the feeding slide plate 53 in the horizontal direction. After the catheter is impregnated with adhesive, the feeding rack 51 is moved toward the mounting box 32. At this time, the catheter is in contact with the surface of the feeding slide plate 53. The feeding pressure plate 52 is moved to abut against the catheter, so that the feeding slide plate 53 and the feeding pressure plate 52 clamp the catheter. Then the feeding rack 51 is moved back to its original position, so that the catheter can be removed from the mounting post 33. Then the feeding pressure plate 52 is moved back to its original position, and the feeding slide plate 53 is moved away from the feeding rack 51. The catheter is then removed from the feeding slide plate 53 by the robotic arm, which facilitates the subsequent processing of the catheter.

[0041] like Figure 2 and 6 As shown, the impregnation frame 21 is equipped with a control component 7, which includes a control gear 71, a first rack 72, a second rack 73, and a control motor 74. The control gear 71 is rotatably connected to the impregnation frame 21, and both the first rack 72 and the second rack 73 mesh with the control gear 71. The mounting box 32 rotates relative to the first rack 72, and a connecting rod 322 is fixedly connected to the mounting box 32, which is rotatably connected to the first rack 72. One end of the second rack 73 is fixedly connected to the feeding rack 41, and the other end is fixedly connected to the discharging rack. The control motor 74 is mounted on the impregnation frame 21, and the rotating shaft 321 of the control motor 74 is fixedly connected to the control gear 71. When the installation box 32, the loading rack 41, and the unloading rack 51 need to be moved, the drive control motor 74 causes the rotating shaft 321 of the control motor 74 to drive the rotation of the control gear 71. The movement of the control gear 71 can drive the movement of the first rack 72 and the second rack 73. The movement of the first rack 72 can drive the movement of the installation box 32, and the movement of the second rack 73 can drive the movement of the loading rack 41 and the unloading rack 51, thereby achieving synchronous movement of the three, which facilitates the installation of the catheter onto the installation post 33 and the removal of the catheter from the installation post 33.

[0042] like Figure 2 and 7 As shown, the mounting box 32 is provided with an auxiliary plate 8, which is attached to the upper surface of the mounting box 32. The auxiliary plate 8 has a through hole for the mounting post 33 to pass through. The auxiliary plate 8 and the mounting box 32 slide relative to each other. The mounting box 32 is provided with an auxiliary component 9, which includes an auxiliary gear 91, a third rack 92, a fourth rack 93, and an auxiliary spring 94. The auxiliary gear 91 is located inside the mounting box 32 and is rotatably connected to the mounting box 32. The third rack 92 and the fourth rack 93 both mesh with the auxiliary gear 91. The third rack 92 is located inside the mounting box 32 and is fixedly connected to the auxiliary plate 8. The fourth rack 93 is fixedly connected to the side of the unloading rack 51 facing the mounting box 32. One end of the auxiliary spring 94 is fixedly connected to the inner wall of the mounting box 32, and the other end is fixedly connected to the third rack 92. Under normal circumstances, the auxiliary spring 94 applies a pulling force to the third rack 92, thereby causing the third rack 92 to apply a pulling force to the auxiliary plate 8, facilitating the contact between the auxiliary plate 8 and the surface of the mounting box 32. When it is necessary to remove the catheter from the mounting post 33, the feed rack 51 moves toward the mounting box 32. The movement of the feed rack 51 can drive the movement of the fourth rack 93, so that the fourth rack 93 passes through the auxiliary plate 8 and the mounting box 32 and meshes with the auxiliary gear 91, thereby causing the auxiliary gear 91 to rotate. The rotation of the auxiliary gear 91 can drive the rotation of the third rack 92, causing the third rack 92 to move away from the mounting box 32. The third rack 92 can push the auxiliary plate 8, causing the auxiliary plate 8 to move away from the mounting box 32, thereby pushing out the catheter on the mounting post 33, making it easy to remove the catheter from the mounting post 33.

[0043] The implementation principle of the automated production line for EVA female external urinary catheters in this application embodiment is as follows: When the catheter needs to be impregnated with adhesive, the catheter is moved onto the feeding slide plate 43, and the feeding pressure plate 42 abuts against the catheter. The first motor 63 drives the mounting box 32 to rotate the mounting post 33, so that the tip of the mounting post 33 faces the feeding rack 41. Then, the control motor 74 moves the feeding rack 41 and the mounting box 32 closer together, thereby placing the catheter onto the mounting post 33. Afterwards, the control motor 74 resets the mounting box 32, and the first motor 63 drives the mounting box 32 to rotate the mounting post 33 into the impregnation box 22 to impregnate the catheter with adhesive. After the catheter is impregnated with adhesive, the first motor 63 moves the tip of the mounting post 33 toward the unloading rack 51, the control motor 74 moves the mounting box 32 and the unloading rack 51 closer to each other, the fourth rack 93 moves the auxiliary plate 8 away from the mounting box 32, and the unloading pressure plate 52 and the unloading slide plate 53 clamp the catheter on the mounting post 33, thereby removing the catheter from the mounting post 33.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
