Description

Technical Field

[0001] The invention relates to the technical field of spring tube processing, in particular to a full-automatic medical spring tube hot-film laminating flexible feeding device. Background Art

[0002] Medical spring tube is a special type of tube used in medical devices and medical equipment. It has certain elasticity and flexibility and is widely used in various medical devices such as endoscopes, guidewires, catheters, stents, etc. The medical spring tube hot lamination flexible feeding device is an automated equipment used to feed the medical spring tube into the hot lamination process for processing.

[0003] Existing medical spring tube loading usually uses a robot for transfer loading, which has the following defects:

[0004] 1. Use a robot to place the spring tube on the conveyor belt in the laminating area. After each placement, the robot needs to return to the material picking area to pick up the material again. This process is a blank period for loading, which can easily cause loading interruptions and affect loading efficiency. If multiple robots are used in combination, encoding settings for different motion paths are required, which is difficult to operate and has high production costs.

[0005] 2. At the same time, in the existing loading method, the spring tube is cleaned and then prepared for lamination. However, before lamination, it is easy to adhere to dust or there is floating dust in the processing area. The spring tube and the spring tube processing area during the loading process are not dust-removed, which can easily cause dust to be entrained into the spring tube and the film during the later lamination, affecting the lamination effect.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0037] Example 1

[0038] See also Figure 1-6 In the present invention, a fully automatic medical spring tube hot coating flexible feeding device includes a motor 1, the output end of the motor 1 is fixedly connected to a mounting block through a coupling, hydraulic rods 2 are installed on the upper and lower sides of the mounting block, feeding mechanisms 4 are provided on the upper and lower sides of the motor 1, and a coating component 3 is provided on the outer side of the bottom feeding mechanism 4.

[0039] A servo 14 is installed on the outside of the hydraulic rod 2. The output end of the servo 14 is fixedly connected to a connecting shaft 15 through a coupling. The back end of the connecting shaft 15 passes through and is rotatably connected to the outside of the hydraulic rod 2. The connecting shaft 15 passes through and is fixedly connected to the outside of the cross plate 41.

[0040] In the present invention, during the laminating process, the top loading mechanism 4 can be used in advance to prepare the storage of the spring tube, and then the motor 1 can be started to move, so that it drives the hydraulic rod 2 and the corresponding loading mechanism 4 to be transported. During the movement, the servo 14 can be used in conjunction with the connecting shaft 15 to adjust the angle of the cross plate 41. After the top cross plate 41 moves to the bottom, the cross plate 41 is rotated one hundred and eighty degrees compared with the original state, and the hydraulic rod 2 is used to perform a contraction movement during the movement to reduce the accidental collision between the loading mechanism 4 and the laminating component 3. After the movement is completed, the spring tube on the cross plate 41 that moves to the bottom is loaded before laminating. At this time, the cross plate 41 that moves from the bottom to the top is used to prepare the spring tube. After the loading process of the spring tube before laminating is completed, the motor 1 is started again to rotate, so that the two loading mechanisms 4 perform preparation and loading operations alternately, shortening the loading blank period and improving processing efficiency. The equipment occupies a small space and is more in line with production needs.

[0041] Example 2

[0042] Based on the above examples, please refer to Figure 1-6, wherein: the feeding mechanism 4 includes a horizontal plate 41, a group of electric push rods 42, a group of clamping boxes 43 and push plates 44 arranged opposite to each other, the two clamping boxes 43 are provided with arc surfaces on the opposite sides to facilitate the introduction of the spring tube when preparing materials, the electric push rod 42 is located between the two clamping boxes 43 and embedded in the inside of the horizontal plate 41, and the push plate 44 is installed on the top of the electric push rod 42.

[0043] The interior of the clamping box 43 is slidably connected to the piston plate 5, and a pull rope 6 is installed at the bottom of the piston plate 5. Guide rollers 7 rotatably connected to the inside of the cross plate 41 are provided on the left and right sides of the electric push rod 42 to guide the pull rope 6. One end of the pull rope 6 is wrapped around the outside of the guide roller 7 and fixedly connected to the bottom of the push plate 44. A group of first conduits 8 and a group of second conduits 9 are installed on the opposite sides of the two clamping boxes 43. The second conduits 9 are on the arc surface. A one-way valve 10 is installed on the outside of the first conduit 8 and the second conduit 9. The outside of the pull rope 6 is provided with a first spring 11 inside the clamping box 43. The top of the first spring 11 is fixedly connected to the bottom of the piston plate 5, and the bottom end of the first spring 11 is fixedly connected to the inner bottom wall of the clamping box 43.

[0044] In the present invention, when the horizontal plate 41 at the bottom is discharging the spring tube, that is, when the material is being fed before laminating, the movable end of the electric push rod 42 is directed downward, and the electric push rod 42 can be used to move to drive the push plate 44 to drive the spring tube to move downward. During the movement, the pull rope 6 will pull the piston plate 5, so that the inside of the clamping box 43 is in a negative pressure state. At this time, the one-way valve 10 on the first conduit 8 is opened by pressure, and then the first conduit 8 is used to perform dust collection on the outside of the spring tube during the feeding process (such as Figure 5 shown).

[0045] After the spring tube is loaded, that is, the spring tube is on the left conveyor belt 31 and separated from the clamping box 43, the electric push rod 42 will drive the push plate 44 to reset. During the reset process, the first spring 11 will push the piston plate 5 to reset, so that the gas inside the clamping box 43 will be discharged to the outside. At this time, the one-way valve 10 on the second conduit 9 is pressurized and opened, and then the gas is ejected along the second conduit 9 to the outside of the spring tube. After the gas is guided by the spring tube, the area where the spring tube is located is blown and dusted (such as Figure 6 As shown), it ensures a better laminating environment and reduces the dust entrainment during the subsequent laminating process, thus ensuring the laminating effect.

[0046] See also Figure 1-2 , wherein: the bottom of the clamping box 43 is provided with a sliding block 12 slidably connected to the inside of the horizontal plate 41, and the side of the sliding block 12 away from the push plate 44 is fixedly connected to a second spring 13 installed inside the horizontal plate 41.

[0047] In the present invention, the second spring 13 is combined with the sliding block 12 to clamp and fix spring tubes of different specifications, with a flexible clamping effect and greater applicability. For the preparation of the spring tube, a material guide mechanism can directly guide the spring tube into the corresponding two clamping boxes 43.

[0048] See also Figure 1-6 , wherein: the laminating assembly 3 includes two conveyor belts 31, two sets of film guide rollers 32, a hot melt component 33 and a chassis 34, the left conveyor belt 31 is arranged below the bottom horizontal plate 41, the two conveyor belts 31 are arranged horizontally, the chassis 34 is installed to the outside of the right conveyor belt 31, the two sets of film guide rollers 32 are installed to the inside of the chassis 34 and are distributed up and down, the hot melt component 33 is installed to the inside of the chassis 34; the hot melt component 33 includes a cylinder 331, a frame 332 and a frame-shaped hot melt strip 333, the cylinder 331 is installed to the inner top wall of the chassis 34, the frame 332 is installed to the bottom end of the cylinder 331, and the frame-shaped hot melt strip 333 is installed to the bottom of the frame 332; a heating box 16 connected to it is installed on the right side of the chassis 34.

[0049] In the present invention, after the spring tube is transported to the left conveyor belt 31 and loaded, the left conveyor belt 31 is used to transport the spring tube to the right conveyor belt 31. After being transported to the right conveyor belt 31, the films on the two sets of film guide rollers 32 will be on the upper and lower sides of the spring tube respectively. Then, when the spring tube moves to the bottom of the cylinder 331, the conveyor belt 31 stops, and then the cylinder 331 drives the frame 332 and the frame-shaped hot melt strip 333 to move downward, and the films on the upper and lower sides of the spring tube are hot-melted and separated. Then, the spring tube and the film wrapped around its outside are moved to the inside of the heating box 16 by the right conveyor belt 31 for heating treatment, completing the heat shrinkage operation of the film and completing the coating.

[0050] See also Figure 1-6 , wherein: a filter plate 17 is installed inside the clamping box 43, and the filter plate 17 is located between the first conduit 8 and the second conduit 9; and in order to complete the dust removal inside the clamping box 43, a cleaning port (not shown in the figure) can be opened in the non-operating area of ​​the clamping box 43 to complete the dust collection and cleaning operation.

[0051] In the present invention, the filter plate 17 is used to intercept the dust after the dust collection operation, thereby reducing the phenomenon of pushing the dust to the outside during the air jet dust removal.

[0052] It should be noted that the circuit connection relationships of the devices in this application all belong to simple series and parallel connection circuits. There is no innovation in the circuit connection. Those skilled in the art can implement it relatively easily. It belongs to the existing technology and will not be elaborated on.

[0053] The above is a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
