Detailed implementation manners

[0018] Next, the technical solutions of the present application will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0019] Next, in conjunction with Figures 1 - 7 , the medical clamp 920 rubber ring 910 assembly device provided in the embodiment of the present application will be described.

[0020] Refer to Figure 1 , Figure 2 , Figure 6 , Figure 7As shown in the figure, the rubber ring 910 assembling device for the medical clip 920 provided by the embodiment of the present application includes a fixing frame 100, an expanding mechanism 200, a clamping mechanism 300 and a baffle 400, which are used to sleeved the rubber ring 910 on the medical clip 920. The expanding mechanism 200 is installed at the upper end of the fixing frame 100 and is used to expand the rubber ring 910; the clamping mechanism 300 is located below the expanding mechanism 200 and is arranged opposite to the expanding mechanism 200, and the clamping mechanism 300 is used to clamp the medical clip 920; the baffle 400 is located between the expanding mechanism 200 and the clamping mechanism 300, and an avoidance hole is formed on the baffle 400. At least part of the expanding mechanism 200 can penetrate through the avoidance hole, and the baffle 400 can also block the expanded rubber ring 910 from penetrating through the avoidance hole. The expanding mechanism 200 expands the inner diameter of the rubber ring 910 so that it can be smoothly sleeved on the medical clip 920 downward. The baffle 400 can block the rubber ring 910 from retracting upward during the process of the expanding mechanism 200 retracting upward, so that the rubber ring 910 is sleeved on the medical clip 920.

[0021] Referring to Figure 3 , Figure 4 As shown in the figure, in some specific embodiments, the expanding mechanism 200 includes at least three expanding heads. For example, the expanding heads are four arranged in a ring shape, and the four expanding heads expand the inner diameter of the rubber ring 910 by moving radially along the rubber ring 910. Specifically, each expanding head includes a sleeve rod 210 and a connecting block 220. The sleeve rod 210 can penetrate through the avoidance hole, and the side wall of the sleeve rod 210 abuts against the inner wall of the rubber ring 910; the connecting block 220 is connected to the end of the sleeve rod 210 and is used to drive the sleeve rod 210 to move radially along the rubber ring 910.

[0022] In some embodiments, a cylindrical surface is formed on the side wall of the sleeve rod 210 close to the inner wall of the rubber ring 910. For example, the sleeve rod 210 is a quarter cylinder, and the four sleeve rods 210 form a complete cylinder after combination. A quarter conical surface is formed at the end of the sleeve rod 210, and the ends of the four sleeve rods 210 can form a complete conical surface after combination. In this way, it is convenient for the sleeve rod 210 to be smoothly inserted into the unexpanded rubber ring 910.

[0023] In some embodiments, a heating rod is further disposed between the four sleeve rods 210. The heating rod is cylindrical. For example, the heating rod is an electric heating rod. The four sleeve rods 210 are respectively disposed around the heating rod. In this way, the sleeve rods 210 can be heated by the heating rod, so that the temperature of the sleeve rods 210 is maintained within a certain range. Thus, after the unexpanded rubber ring 910 is sleeved on the sleeve rods 210, the temperature of the part where the rubber ring 910 is in direct contact with the sleeve rods 210 can be increased, making it soft. In this way, the temperature of the part where the rubber ring 910 is in direct contact with the sleeve rods 210 is relatively high, while the temperature of other parts is relatively low. Experiments have shown that during the expansion process, the rubber ring 910 in direct contact with the sleeve rods 210 is subjected to the greatest tensile force and is most likely to break. This can prevent the position where the rubber ring 910 is in direct contact with the sleeve rods 210 from breaking during the expansion process. At the same time, the other parts of the rubber ring 910 can still maintain a relatively low temperature, so that the overall rubber ring 910 can have a certain axial supporting force to prevent the rubber ring 910 from being too soft and wrinkling during the process of pulling out the sleeve rods 210.

[0024] In a possible design, the expansion mechanism 200 further includes a guide seat 230, a guide block 240, and a first driving member 250. The guide seat 230 is cylindrical. Four guide rails are formed on the lower end surface of the guide seat 230 and are distributed radially along the guide seat 230. Correspondingly, there are also four guide blocks 240. The guide blocks 240 are respectively disposed in the guide rails one by one. The upper end of the guide block 240 is slidably engaged with the guide rail. The lower end of the guide block 240 is connected to the connecting block 220 by screws. The first driving member 250 is installed on the guide seat 230. The first driving member 250 is a multi-piston cylinder. Each piston is respectively connected to a different guide block 240 through a connecting rod. When the multi-piston cylinder intakes or exhausts air, multiple pistons act simultaneously, pushing the respective connected guide blocks 240 to expand and contract along their respective guide rails, realizing the unified control of four guide blocks 240 by one air source, ensuring the synchronism of the actions of the four guide blocks 240. When the guide blocks 240 move, they simultaneously drive the connecting block 220 and the sleeve rods 210 to move radially.

[0025] Refer to Figure 5 As shown, convex edges 410 extending radially along the inner wall of the avoidance hole of the baffle 400 are arranged at intervals. A reserved space for the sleeve rod 210 to pass through is formed between two adjacent convex edges 410. Specifically, the avoidance hole is square, and the four convex edges 410 are respectively disposed on the four inner walls of the avoidance hole. The sleeve rods 210 can respectively pass through the positions of the four corners of the avoidance hole. When the sleeve rods 210 expand the rubber ring 910, the inner diameter of the rubber ring 910 is larger than the inner diameter of the four convex edges 410. Only in this way, when the sleeve rods 210 move upward, the four convex edges 410 can block the upward movement of the rubber ring 910, thereby retaining the rubber ring 910 on the medical clip 920.

[0026] Refer to Figure 1 、 Figure 2As shown in the figure, the assembly device for the rubber ring 910 of the medical clip 920 further includes a first linear module 500, a second linear module 600, a movable seat 700, and a second driving member 800. The first linear module 500 is horizontally installed on the fixed frame 100. The second linear module 600 is vertically arranged and connected to the slider of the first linear module 500. The movable seat 700 is connected to the slider of the second linear module 600. The expansion mechanism 200 and the baffle 400 are both installed on the movable seat 700. In this way, the first linear module 500 drives the movable seat 700 to move left and right, realizing the overall synchronous left and right movement of the expansion mechanism 200 and the baffle 400. The second linear module 600 drives the movable seat 700 to move up and down, realizing the overall synchronous up and down movement of the expansion mechanism 200 and the baffle 400. The second driving member 800 is installed on the movable seat 700. The second driving member 800 uses a motor or a cylinder, and the driving end is connected to the guide seat 230. The second driving member 800 drives the guide seat 230 to move down close to the clamping mechanism 300 to sleave the rubber ring 910 on the medical clip 920. The second driving member 800 drives the guide seat 230 to move up away from the clamping mechanism 300 to retract the sleeve rod 210. At the same time, the baffle 400 blocks the upward movement of the rubber ring 910 to retain the rubber ring 910 on the medical clip 920.

[0027] In some specific embodiments, the clamping mechanism 300 includes a first fixture 310, a second fixture 320, and a third driving member 330. The shapes of the first fixture 310 and the second fixture 320 are adapted to the shape of the medical clip 920. The second fixture 320 is arranged opposite to the first fixture 310. The medical clip 920 is placed between the first fixture 310 and the second fixture 320. The third driving member 330 uses a motor or a cylinder, and the driving end of the third driving member 330 is connected to the second fixture 320. The second fixture 320 is moved closer to the first fixture 310 to clamp the medical clip 920, and the second fixture 320 is moved away from the first fixture 310 to release the medical clip 920.

[0028] The working process of the assembly device for the rubber ring 910 of the medical clip 920 in this application: The third driving member 330 acts to move the second fixture 320 closer to the first fixture 310 to clamp the medical clip 920; The first linear module 500 acts to drive the sleeve rod 210 and the baffle 400 to move horizontally synchronously to the picking and placing table of the rubber ring 910; The second driving member 800 acts to move the sleeve rod 210 downwards. The sleeve rod 210 passes through the avoidance hole of the baffle 400 and inserts into the rubber ring 910 on the picking and placing table; The first driving member 250 acts to push the four guide blocks 240 to move outwards synchronously along their respective guide rails, causing the four sleeve rods 210 to move radially synchronously, and expanding the inner diameter of the rubber ring 910; The first linear module 500 operates to drive the sleeve rod 210 and the baffle 400 to move horizontally synchronously as a whole to directly above the clamping mechanism 300, so that the rubber ring 910 is directly above the medical clip 920; The second linear module 600 operates to drive the sleeve rod 210 and the baffle 400 to move downward synchronously as a whole, so that the rubber ring 910 moves downward, and one end of the medical clip 920 extends upward outside the rubber ring 910; The second driving member 800 and the first driving member 250 operate simultaneously. While the four sleeve rods 210 move upward, they synchronously move radially inward. The four sleeve rods 210 are withdrawn from the avoidance holes of the baffle 400. The rubber ring 910 is blocked by the convex edge 410 on the baffle 400 and stays on the medical clip 920. The rubber ring 910 retracts and tightly sleeves on the medical clip 920 to complete the assembly.
