Description

Technical Field

[0001] The utility model relates to the technical field of medical device manufacturing, and particularly relates to a double-station ablation needle primary packaging sealing device. Background Technique

[0002] In the technical field of medical device manufacturing, the primary packaging sealing of cryoablation needles is a key link. Traditionally, the primary packaging process of ablation needles includes loading the ablation needles into a blister box and sealing the blister box with Tyvek paper. This step is crucial for protecting the ablation needles from external environmental interference and ensuring their safety during storage and transportation.

[0003] However, the traditional sealing method has obvious deficiencies in terms of efficiency and automation. Generally, operators need to manually place the Tyvek paper on the blister box and fix it on the blister box by some means (such as heat pressing, tape, etc.). This manual operation is not only inefficient but also prone to problems such as loose sealing and deviation of the position of the Tyvek paper, thus affecting the quality and aesthetics of the packaging.

[0004] To solve this problem, the industry has started to explore the application of automated sealing equipment. However, the existing automated sealing equipment often can only operate in a single station, that is, it can only process the sealing of one blister box at a time, which to a certain extent limits the improvement of production efficiency. In addition, these equipment also have deficiencies in the positioning and fixing of Tyvek paper, and are prone to problems such as inaccurate positioning and insecure fixing.

[0005] In view of the above problems, a double-station ablation needle primary packaging sealing device is proposed. Content of the Utility Model

The limit post installation holes are stepped holes with a larger lower aperture than the upper aperture. The upper rod of the limit post has a clearance fit with the upper hole of the stepped hole. The outer diameter of the shoulder of the limit post is larger than the upper hole of the stepped hole.

[0010] The elastic element is a spring. A bottom cover is arranged at the bottom of the stepped hole. The bottom cover is fixedly connected to the static plate. The spring is installed between the shoulder of the limit post and the bottom cover.

[0011] The heating element is an electric heating tube. The electric heating tube is installed in a tube groove provided at the top of the moving plate.

[0043] As Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 12 shown, the double-station ablation needle primary packaging sealing device is used to bond the Tyvek paper 5 to the opening of the blister box of the ablation needle. There is an adhesive on the back of the Tyvek paper 5 that has adhesive performance after being softened by heating. It includes a static plate 21, a moving plate 34 and a frame 4. Two horizontally arranged static plates 21 are fixed on the frame 4. A groove 212 for placing the blister box is provided on the static plate 21. A number of limit posts 22 that can move in the vertical direction are provided around the groove 212. An elastic element that always applies an upward force to the limit posts 22 is provided on the static plate 21. In the initial state, the top of the limit posts 22 protrudes from the upper surface of the static plate 21 under the action of the elastic element; corresponding to the two static plates 21, two moving plates 34 are respectively installed on the frame 4 so as to be movable in the vertical direction through two sets of driving devices. A heating element is installed on the moving plate 34.

[0044] As Figure 7 shown, the limit post 22 is composed of an upper rod 221 of the limit post, a shoulder 222 of the limit post and a lower rod 223 of the limit post. A limit post installation hole is provided on the static plate 21. The limit post installation hole is a stepped hole with a larger lower hole diameter than the upper hole diameter. The upper rod 221 of the limit post is in clearance fit with the upper hole of the stepped hole. The outer diameter of the shoulder 222 of the limit post is larger than the upper hole of the stepped hole.

[0045] The elastic element is a spring 23. A bottom cover 24 is provided at the bottom of the stepped hole. The bottom cover 24 is fixedly connected to the static plate 21. The spring 23 is installed between the shoulder 222 of the limit post and the bottom cover 24.

[0046] As Figure 8 shown, the heating element is an electric heating tube 33. The electric heating tube 33 is installed in the tube groove 341 provided at the top of the moving plate 34.

[0047] A guiding structure is provided between the frame 4 and the moving plate 34.

[0048] As Figure 9 shown, the guiding structure includes a moving plate slider 342 and a slideway 41. The moving plate sliders 342 are provided on both sides of the moving plate 34, and the slideway 41 cooperating with the moving plate sliders 342 is provided on the frame 4.

[0049] The driving device includes a push rod motor 31 fixedly installed on the frame 4, and the moving plate 34 is fixedly connected to the end of the push rod 311 of the push rod motor 31.

[0050] As Figure 13 shown, a positioning hole 211 is provided on the top surface of the static plate 21, and a positioning post 344 cooperating with the positioning hole 211 is provided on the bottom surface of the moving plate 34.

[0051] The double-station ablation needle primary packaging sealing device further includes a control console 1, and the control console 1 is communicatively connected to the driving device and the heating element; the control console 1 includes a PLC with a touch screen, and the interface is as Figure 3 and Figure 4 shown.

[0052] In a specific embodiment:

[0053] The double-station ablation needle primary packaging sealing device includes a control console, 2 mother board assemblies, 2 driving assemblies, and a frame.

[0054] For the primary packaging sealing of the ablation needle, the ablation needle needs to be loaded into the blister box, and then the blister box is sealed with Tyvek paper; the control console controls the primary packaging sealing of the ablation needle at two stations and can adjust the sealing speed of the device; in addition, the temperature of the electric heating tube can also be adjusted; in addition, the sealing quantity and total time of each station are recorded on the control panel, which is convenient for recording.

[0055] The mother board assembly includes a static plate, a limit post, a spring, and a bottom cover.

[0056] The static plate fixes the primary packaging of the ablation needle, that is, the blister box and Tyvek paper.

[0057] The limit post prevents the installation position of the Tyvek paper from deviating and provides a certain buffer for the impact caused by the movement of the moving plate towards the static plate.

[0058] One end of the spring is connected to the limit post, and the other end is fixed to the bottom cover to reset the limit post after the sealing process of the device is completed.

[0059] One end of the bottom cover is fixedly installed at the bottom of the static plate by screws, and one end limits and fixes one side of the spring.

[0060] The driving assembly includes a push rod motor, a moving plate, an electric heating tube, and a top cover.

[0061] The push rod motor provides power and stroke control for the upward and downward movement of the moving plate.

[0062] When the moving plate seals, it moves downward towards the static plate, pressing the Tyvek paper and the blister box to make them fastened.

[0063] The heating pipe is fixed on the moving plate, providing the temperature for softening the back glue of the Tyvek paper to bond it with the blister box.

[0064] The top cover fixes the push rod motor and is bolted to the frame.

[0065] The frame is the fixing frame of the equipment, bolts are used to fix the static plate and the top cover, and it provides a sliding track for the up and down sliding of the moving plate.

[0066] As Figure 2 shown in the explosion diagram, the double-station ablation needle primary packaging sealing equipment includes a control console 1, a motherboard assembly 2, a drive assembly 3, and a frame 4.

[0067] The control console controls the primary packaging sealing of the ablation needles at two stations, and can adjust the stroke and speed of the moving plate as well as the temperature of the heating pipe; in addition, the control panel records the sealing quantity and total time of each station as Figure 3 and Figure 4 shown.

[0068] As Figure 5 shown in the explosion diagram of the motherboard assembly and Figure 6 、 Figure 7 the cross-sectional view of the motherboard assembly, the motherboard assembly 2 includes a static plate 21, a limit post 22, a spring 23, and a bottom cover 24. The specific installation process is as follows. There are variable-diameter through holes of different sizes on the static plate 21. The limit post 22 enters this through hole from the bottom up through the bottom of the static plate 21. The large-diameter bottom surface of the static plate 21 abuts against the shoulder 222 of the limit post, so that the limit post 22 no longer moves upward. At this time, a part of the upper rod 221 of the limit post extends beyond the upper end surface of the static plate 21. The spring 23 moves upward along the lower rod 223 of the limit rod until the shoulder 222 of the limit post restricts the upward movement of the spring 23. The lower rod 223 of the limit rod restricts the radial movement of the spring. And at this time, the spring 23 gives a certain elastic force to the limit post 22 to make the latter in force balance and stationary. The other side of the spring 23 extends into the base limit groove 242. The base limit groove 242 restricts the downward displacement and radial position of the spring 23. The base through hole 241 is screwed and connected with the threaded hole of the static plate 21, so the base 24 is fixed on the lower end surface of the static plate 21.

[0069] As Figure 8As shown in the figure, it is an exploded view of the driving component. The driving component 3 is composed of a push rod motor 31, a top plate 32, an electric heating tube 33, and a moving plate 34. The specific installation method is as follows: The electric heating tube 33 is installed into the tube slot 341. After the fixing small plate 313 of the push rod motor 31 passes through the square hole 321, it is fixed to the end face of the moving plate 34 by screwing with the screw hole 343 of the moving plate; the fixing large plate 312 of the push rod motor 31 is fixed to the upper end face of the top plate 32 by screwing with the screw hole 322 of the top plate. When running, the push rod 311 can be extended and retracted. As Figure 8 shown, there is a slideway 41 on the frame 4, and the moving plate slider 342 moves along the slideway. Therefore, the moving plate slides on both sides of the frame, which can replace the traditional slider connection structure.

[0070] As Figure 10 shown, it is the state before sealing of the double-station ablation needle primary packaging sealing equipment. At this time, the blister box is placed into the groove of the static plate 21, and a part of the limit post 22 extends beyond the static plate 21 to facilitate the installation of Tyvek paper on the blister box. At this time, the state of the mother board assembly is as Figure 7 shown. At this time, the limit post extends beyond the static plate. At this time, the stroke of the push rod 311 of the push rod motor 31 is 0, and the electric heating tube 33 has started working for half an hour, and the preheating is completed.

[0071] When starting the sealing program of the double-station ablation needle primary packaging sealing equipment, the push rod motor 31 is started, and the push rod 311 drives the moving plate 34 to move downward. When the push rod reaches the maximum stroke, as Figure 11 the moving plate 34 moves to the lowest point, the limit post 22 moves downward under the pressure of the moving plate 34, and gives a buffer to the falling of the moving plate 34. At this time, the spring 33 is compressed to give the limit post an elastic force, so that the latter stops at this position, as Figure 12 shown. In addition, the moving plate 34 gives the maximum pressure between the Tyvek paper and the blister box. Since the electric heating tube has been preheated before, the high temperature of the moving plate melts the back glue of the Tyvek paper, completing the sealing process. When the sealing process is over, the push rod motor 31 drives the stroke of the push rod 311 back to 0, and the limit post 22 is reset due to the elastic force of the spring 23.

[0072] To prevent the moving plate 34 from deviating during the installation process or the falling process, there are two positioning posts 344 on the lower end face of the moving plate, and two positioning holes 211 on the upper end face of the static plate 21. Once there is a deviation, the moving plate will not be able to fall to the lowest point. Therefore, the accuracy of the position has a monitoring function.

[0073] This double-station ablation needle primary packaging sealing equipment is convenient to operate and has high automation; double-station processing improves efficiency; the static plate is installed with limit posts to prevent the deviation of the installation position of the Tyvek paper and bring a certain buffer to the impact caused by the movement of the moving plate towards the static plate.
