[0037] The present application is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

The anti-needle-stick shrapnel 221 is fixedly connected, and a slot 21 is opened on the needle tube 2 corresponding to the shrapnel seat 22. The shrapnel seat 22 can be embedded in the slot 21. When the shrapnel seat 22 is embedded in the slot 21, the anti-needle-stick shrapnel 221 abuts against the end of the needle tube 2 and the end of the needle tube 2 passes through the shrapnel seat 22. In specific implementation, when the needle tube assembly is pulled out after the indwelling needle puncture is completed, the anti-needle puncture spring 221 in the spring seat 22 can be triggered so that the needle tip is accommodated in the spring seat 22. At the same time, the slot 21 is engaged with the anti-needle puncture spring 221 in the spring seat 22. The leftmost end of the anti-needle puncture spring 221 rebounds and covers the needle tip through the arc set in the front. At the same time, an upward force is applied to the needle tip, so that the slot 21 on the needle tube 2 is engaged with the anti-needle puncture spring 221, thereby fixing the anti-needle puncture spring 221.

[0040] Working principle: The needle tube 2 is connected to the handle 1 through UV glue. The connection between the needle tube 2 and the handle 1 can further increase stability. At the same time, it can also reduce the situation of needle collision during processing, further improving the processing convenience.

[0041] Embodiment 2 A high connection strength indwelling needle tube assembly processing equipment, such as Figure 3 and Figure 4 As shown, the assembly of the indwelling needle with high connection strength in Example 1 also includes a feeding assembly 3, a clamping assembly 4, a processing assembly 5, and a discharging assembly 6.

During specific implementation, the first mounting seat 531 and the second mounting seat 541 can move toward each other under the push of the corresponding cylinders. During the installation process, the needle tube can be inserted into the handle, and then the tail of the needle tube can be flattened by the flattening cylinder 56.

[0044] like Figure 3 and Figure 5As shown, the processing assembly 5 also includes a glue dripping rack 51, which is arranged on the upper side of the processing table 52. The processing table 52 is also provided with a needle clamp 521 for clamping the needle tube. The glue dripping rack 51 is provided with a glue dripping tank 511 and a glue dripping head 512. The glue dripping tank 511 is used to store UV glue. The glue dripping head 512 is connected to the glue dripping tank 511 through a hose. The glue dripping head 512 is rotatably connected to the glue dripping rack 51 and is adjustable. The glue dripping head 512 is used to drip UV glue toward the handle. In specific implementation, during processing, the needle tube needs to be first sent into the handle by the needle clamp 521, and then the needle tube is flattened, and then the needle tube is clamped out and lifted, and glue is dripped, and then the processed needle tube is sent out.

[0045] like Figure 3 and Figure 5 As shown, the rotating material taking disc 41 is also provided with ultraviolet lamps 411 corresponding to each needle tube clamp 42, and the ultraviolet lamps 411 are used to irradiate the connection between the needle tube 2 and the handle 1. In specific implementation, the needle tube 2 and the handle 1 can be connected during the rotation of the needle tube clamp 42, and the connected needle tube 2 and the handle 1 can also be rotated, and the product can be irradiated with ultraviolet light to accelerate the curing of the UV glue.

[0046] like Figure 3 and Figure 6 As shown, the feeding assembly 3 includes a loading platform 31, a feeding rack 32, and a feeding rack 33. The loading platform 31 is arranged between the feeding rack 32 and the feeding rack 33. A plurality of feeding channels 311 are arranged on the loading platform 31. The feeding channels 311 penetrate the loading platform 31. The feeding channels 311 are arranged at equal intervals along the vertical direction of the loading platform 31. A servo motor 34 for driving the loading platform 31 to move up and down is arranged on the lower side of the loading platform 31. A feeding cylinder 321 is arranged on the feeding rack 32. The piston rod of the feeding cylinder 321 corresponds to the feeding channel 311 of the loading platform 31. A feeding pipe 331 is arranged on the feeding rack 33. A feeding channel 332 is opened in the feeding pipe 331. The feeding channel 332 penetrates the feeding pipe 331 and corresponds to the needle tube clamp 42 on the rotating material picking tray 41. In specific implementation, when feeding, first place multiple needle tubes 2 on the loading platform 31 manually or mechanically. When feeding, the needle tube 2 in each feed channel 311 can be pushed by the feeding cylinder 321. The feeding cylinder 321 passes through the feed channel 311 of the loading platform 31 and pushes the needle tube 2 into the feeding tube 331. The needle tube 2 is sent out to the needle tube clamp 42 under the guidance of the feeding tube 331. At this time, continue to push the needle tube 2 to push the needle tube 2 out of the feeding tube 331, so that it can be clamped by the needle tube clamp 42. After pushing, you only need to control the loading platform 31 to move up and down to complete the discharge, thereby further improving the convenience of feeding.

[0047] like Figure 3 and Figure 6 As shown, a guide frame 35 is further provided at the lower side of the loading platform 31, a screw rod 341 is provided on the rotating shaft of the servo motor 34, the screw rod 341 is threadedly connected to the loading platform 31, a guide rod 351 is provided on the guide frame 35, the loading platform 31 is slidably connected to the guide rod 351, and when the screw rod 341 rotates, the loading platform 31 can slide up and down along the guide rod 351. In other embodiments, a cylinder can also be used to drive the loading platform 31.

[0048] like Figure 3 and Figure 6 As shown, a limit rod is provided at the lower side of the feed rack 32, and the limit rod is used to abut against the loading platform 31. When the limit rod abuts against the loading platform 31, the piston rod of the feed cylinder 321 is aligned with the material passage 311 at the top of the loading platform 31. In specific implementation, the limit rod can abut against the loading platform 31 to limit the displacement of the loading platform 31 and reduce the situation of excessive displacement.

[0049] like Figure 3 and Figure 6 As shown, the discharging assembly 6 includes a discharging conveyor belt 61 , and the discharging conveyor belt 61 is arranged on the lower side of the rotating material taking tray 41 .

[0050] Working principle: The needle tube 2 is sent into the loading platform 31 and pushed by the feeding cylinder 321. The feeding cylinder 321 can send the needle tube 2 to the processing component 5 for processing, and then the needle tube 2 and the handle are hinged by UV glue to realize processing.

[0051] Embodiment 3 like Figure 7 As shown, the main difference between the third embodiment and the second embodiment is that the third embodiment is further provided with a flattening assembly 7 beside the loading platform 31, and the flattening assembly 7 includes a flattening track 71, on which a flattening cylinder 72 is slidably provided, and a flattening block 73 is provided on the piston column of the flattening cylinder 72, and a flattening groove 731 corresponding to the shape of a needle tube is provided in the flattening block 73. An air pumping groove 732 is also provided in the flattening block 73, and the air pumping groove 732 is connected to the flattening groove 731, and an air pump is also provided on the flattening block 73 corresponding to the air pumping groove 732, and the air pump is connected to each air pumping groove 732. During specific implementation, in order to facilitate the alignment of the needle tube 2 and the handle, each needle tube 2 is preferably clamped in the same position when transported to the needle tube clamp 42. If the initial positions of each needle tube 2 are different, it is difficult for the feed cylinder 321 to push the needle tube 2 to the position required for processing. Therefore, providing a flattening block 73 is more convenient for flattening each needle tube 2, reducing the situation where the needle tube 2 has different positions when being fed into the needle tube clamp 42, and further increasing the accuracy of processing.

[0052] like Figure 7As shown, the flattening block 73 is also provided with an adsorption groove 733, one end of which is connected to the air extraction groove 732, and the other end of the air extraction groove 732 is arranged close to the loading platform 31. When the flattening block 73 abuts against the loading platform 31, the air extraction groove 732 is blocked. In specific implementation, when the flattening block 73 abuts against the loading platform 31, the flow channel is blocked, and no air leakage occurs. The needle tube 2 can be normally drawn out for flattening. However, when the flattening block 73 is not abutted, air will be extracted from the adsorption groove 733 during air extraction, making it difficult to extract the needle tube 2. Therefore, it is impossible to extract air to flatten the needle tube 2, and air extraction can only be continued after the flattening block 73 abuts, thereby further improving the accuracy of flattening. In other embodiments, a rubber pad can also be arranged at the position of the loading platform 31 corresponding to the adsorption groove 733 to increase the sealing during adsorption and further reduce air leakage.

[0053] Working principle: The basic working principle is the same as that of the second embodiment, but on the basis of the second embodiment, a component capable of flattening each needle tube 2 is added, so that each needle tube 2 can be more accurately delivered into the needle tube clamp 42 at the same position when clamped.

[0054] Embodiment 4 like Figure 8 As shown, the main difference between Example 4 and Example 3 is that a matching groove 734 is provided in the loading platform 31 of Example 4 corresponding to the adsorption groove 733, one end of the matching groove 734 is connected with the material transfer channel 311, and one end of the matching groove 734 can be connected with the matching groove 734, and a rubber sheet 735 is fixedly provided on the side of the matching groove 734 close to the material transfer channel 311. During specific implementation, the rubber sheet 735 has a tendency to move toward the feed channel 311 under normal conditions, and can form friction with the needle tube 2 to a certain extent, thereby reducing the movement speed of the needle tube 2. However, it is difficult for the feed cylinder 321 to play a significant deceleration role under the movement of a longer distance. Therefore, when flattening is performed, when the flattening block 73 is not in contact with the loading platform 31, the rubber sheet 735 can prevent the air pump from sucking out the needle tube 2, and can also prevent the flattening speed from being too fast and causing an impact. At the same time, the air pump can suck the rubber sheet 735 toward the matching groove 734 when inhaling, thereby reducing the impact on flattening. After flattening is completed, the position of the needle tube 2 can also be stabilized, further improving the accuracy of processing.

[0055] Working principle: The basic working principle is the same as that of the third embodiment, but a matching groove 734 and a rubber sheet 735 are added to determine whether flattening is accurate, which further improves the flattening effect and thus improves the accuracy of subsequent processing.

[0056] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
