[0026] Example 1

[0027] Reference Figures 1 to 4 This embodiment provides an automatic riveting connection device for a medical spring tube, comprising a base 100, a guide column 101 being provided on the base 100, a lifting block 102 being provided on the guide column 101, a crimping block 103 being provided on the side of the lifting block 102, and a first arc groove 103a being provided on the bottom of the crimping block 103;

[0028] A pressure platform 200 is provided on the base 100 . A delivery pipe 300 is provided on the pressure platform 200 in the transverse direction. A catheter platform 400 is provided in the longitudinal direction. A spring tube 301 is provided in the delivery pipe 300 . A sleeve 401 is provided on the catheter platform 400 .

[0029] In this embodiment, the purpose of this device is to set a sleeve at the end of the medical spring tube and crimp it to fix it. The purpose of setting the sleeve on the medical spring tube is to make the spring tube and the surgical forceps fixed more firmly. There are two guide columns 101, and the lifting block 102 is driven by air pressure to control the lifting and moving of the lifting block 102 to crimp and fix the spring tube 301 with the sleeve 401 set on the pressure platform 200. The delivery tube 300 is used to transport the spring tube 301. The spring tube 301 is set in the delivery tube 300 through the spring tube vibration screening device and is pushed to move.

[0030] The cannula 401 is placed on the catheter platform 400 for transportation.

[0031] The pressure platform 200 and the catheter platform 400 are provided with a slide groove 402 , and the sleeve 401 is arranged in the slide groove 402 .

[0032] It should be noted that the sliding groove 402 is inclined downward toward the pressure platform 200, so the sleeve 401 thereon can slide downward into the second arc groove 402a by itself.

[0033] A pipe groove 201 is horizontally arranged on the upper side of the pressure platform 200 . The pipe groove 201 passes through the slide groove 402 . The slide groove 402 is arranged corresponding to the end of the conveying pipe 300 . An arc slope 201 a is arranged at the end of the pipe groove 201 .

[0034] The end of the spring tube 301 can be tilted along the arc slope 201a.

[0035] A second arc groove 402a is provided in the sliding groove 402 corresponding to the first arc groove 103a. The second arc groove 402a is provided corresponding to the tube groove 201. When the sleeve 401 is placed in the second arc groove 402a, the inner wall of the sleeve 401 is flush with the bottom of the tube groove 201.

[0036] That is, the depth of the second arc groove 402 a is the same as the wall thickness of the sleeve 401 , so when the sleeve 401 is placed in the second arc groove 402 a , the spring tube 301 slides in the tube groove 201 and can pass through the sleeve 401 .

[0037] The pressure platform 200 is provided with an end block 202 and a side block 203 . The end block 202 is provided at the end of the tube groove 201 , and the side block 203 is provided at the side of the tube groove 201 . A through groove 204 is left between the end block 202 and the side block 203 .

[0038] A sub-screen plate 403 is provided on the catheter platform 400. The sub-screen plate 403 includes a first vertical plate 403a and a second vertical plate 403b. The first vertical plate 403a is provided with a square hole 403c, and the end of the second vertical plate 403b is provided with a cone tip 403d.

[0039] The distance between the first vertical plate 403a and the second vertical plate 403b is the thickness of a sleeve 401. The screen plate 403 is driven to rise and fall by a hydraulic mechanism, and is used to separate multiple sleeves 401 set in the slide groove 402, and move the first sleeve 401 out separately and move it to the second arc groove 402a for crimping.

[0040] A first vertical slot 404 and a second vertical slot 405 are provided on the catheter platform 400 . The first vertical plate 403 a is disposed in the first vertical slot 404 , and the second vertical plate 403 b is disposed in the second vertical slot 405 .

[0041] Specifically, multiple sleeves 401 are arranged in the slide groove 402. In the initial state, the sleeves 401 are all separated above the side of the second vertical plate 403b. When the second vertical plate 403b is lifted, the first vertical plate 403a is separated in the middle of the slide groove 402, and the sleeves 401 are all moved to the side above the first vertical plate 403a. When the second vertical plate 403b is lowered, the second vertical plate 403b separates the first sleeve 401 between the first vertical plate 403a and the second vertical plate 403b, and during the lowering process of the first vertical plate 403a, the first sleeve 401 will pass through the square hole 403c and slide into the second arc groove 402a.

[0042] The pressure platform 200 is further provided with a transverse groove 205 , in which a push plate 205 a is provided.

[0043] The push plate 205 a can also be driven by air pressure. The transverse groove 205 is provided between the end block 202 and the tube groove 201 .

[0044] The push plate 205a is used to push the end of the spring tube 301 after the crimping is completed, so that it moves into the through groove 204. The spring tube is then pushed into the through groove 204, and then the push plate 205a is withdrawn. At this point, the crimping of one spring tube is completed. After passing through the through groove 204, the spring tube is continued to be transported to the next process by other power, and the next spring tube is transported to the tube groove 201 for further crimping.

[0045] Therefore, the present invention can realize automatic crimping of the spring tube after being matched with the sensor.

[0046] Specifically, first, the sieve plate 403 moves to move the sleeve 401 to the second arc groove 402a, and then the spring tube is driven to pass through the sleeve 401. The end of the spring tube contacts the end block 202, and then the crimping block 103 presses down to crimp the sleeve 401, and then the push plate 205a is driven to enter the through groove 204 and push the spring tube to move to the next process. The specific driving device can be set in the through groove 204, and then the next sleeve 401 moves to the second arc groove 402a to continue working.

[0047] It will be appreciated that in the development of any actual embodiment, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will, for those of ordinary skill having the benefit of this disclosure, be a routine undertaking of design, fabrication, and production without undue experimentation.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
