DETAILED DESCRIPTION

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0054] Example

[0055] like Figure 3 As shown, the present drop chamber loading assembly machine includes a bracket 001, on which a drop chamber material taking device 100 and a transverse driving mechanism 002 are provided. The transverse driving mechanism 002 is provided with a first driving mechanism 003, which is connected to the catheter clamping device 200. The transverse driving mechanism 002 is an electric cylinder, and the first driving mechanism 003 is a driving cylinder. Figure 4 As shown, the catheter clamping device 200 includes a catheter front end tube clamping assembly 201, a catheter middle tube clamping assembly 202, and a catheter rear end tube clamping assembly 203. The catheter middle tube clamping assembly 202 and the catheter rear end tube clamping assembly 203 are fixed on a second lifting plate 204. The second lifting plate 204 is also provided with a second driving mechanism 206. The second driving mechanism 206 is connected to the catheter front end tube clamping assembly 201, and the second driving mechanism 206 is a driving cylinder.

[0056] like Figure 20 As shown, the drip chamber material taking device 100 includes a drip chamber clamping finger assembly 101 and a drip chamber clamping adjustment assembly 102. The drip chamber clamping finger assembly 101 is fixed on the first lifting plate 103, and the first lifting plate 103 is connected to the first longitudinal driving mechanism 104. The drip chamber clamping adjustment assembly 102 is connected to the second longitudinal driving mechanism 105, and the second longitudinal driving mechanism 105 is arranged on the first lifting plate 103.

[0057] like Figure 3As shown, the first drop chamber 004 is located on the drop chamber jig 011, the drop chamber taking device 100 is located above the first drop chamber 004, and the catheter clamping device 200 is located on the side of the drop chamber taking device 100. When the drop chamber taking device 100 is in working condition, the first longitudinal driving mechanism 104 drives the drop chamber clamping finger assembly 101 and the drop chamber clamping adjustment assembly 102 to move downward, and the drop chamber clamping finger assembly 101 and the drop chamber clamping adjustment assembly 102 are in a non-clamping state. When moving to the first drop chamber 004, the drop chamber clamping finger assembly 101 clamps one end of the first drop chamber 004, the drop chamber clamping adjustment assembly 102 clamps the other end of the first drop chamber 004, the first longitudinal driving mechanism 104 drives the first drop chamber 004 to move upward, the first drop chamber 004 is aligned with the catheter 007 on the catheter clamping device 200, and the catheter clamping device 200 is waiting to assemble the catheter 007 to the interface 006 of the first drop chamber 004. The first driving mechanism 003 drives the second lifting plate 204 to move downward, and drives the catheter front end clamping assembly 201, the catheter middle part clamping assembly 202 and the catheter rear end clamping assembly 203 to move downward to the catheter 007, the catheter front end clamping assembly 201 clamps the front end of the catheter 007, the catheter middle part clamping assembly 202 clamps the front end of the catheter 007, and the catheter rear end clamping assembly 203 clamps the rear end of the catheter 007.

[0058] After the drop chamber taking device 100 completes the clamping of the first drop chamber 004 and the catheter clamping device completes the clamping of the catheter 007, the catheter clamping device moves to the first drop chamber 004 and inserts the front end of the catheter 007 into the corresponding interface 006 of the first drop chamber 004. The assembled first drop chamber 004 needs to be placed on the drop chamber jig 011 again, and before the drop chamber taking device 100 and the catheter clamping device 200 move downward, the catheter front end clamping assembly 201 releases the catheter 007, and the second driving mechanism 206 drives the catheter front end clamping assembly 201 to move upward by a certain distance, at this time the catheter 007 is in a relaxed state, even if the drop chamber taking device 100 and the catheter clamping device 200 are slightly out of sync during the downward movement process, there will be no pipe pulling phenomenon. By clamping the catheter 007 at multiple points, even if the catheter front end clamping assembly 201 releases the catheter 007, the middle part of the catheter 007 will not sag, reducing the tension of the catheter 007. The transverse driving mechanism 002 drives the first driving mechanism 003 and the catheter clamping device 200 to move transversely, the first driving mechanism 003 drives the catheter clamping device 200 to move longitudinally, and the first driving mechanism 003 adopts a small-power driving cylinder, so that the whole drop chamber feeding and assembling machine has small volume, occupies small space, and has low energy consumption and low cost.

[0059] As shown in the drawings, Figure 4 , 5As shown, the catheter front end clamping assembly 201 includes a first catheter clamping jaw cylinder 207, a first catheter clamping jaw cylinder 207 is provided with a first catheter clamping jaw 208 and a second catheter clamping jaw 209, the first catheter clamping jaw cylinder 207 is fixed on the first connecting plate 210, and the first connecting plate 210 is also provided with a catheter pressing plate 211 located on the side of the first catheter clamping jaw 208 and the second catheter clamping jaw 209. Figure 6 As shown, the catheter pressing plate 211 has an open guide port 212 and a positioning port 213 connected with the guide port 212.

[0060] Because the catheter 007 is soft, when the catheter 007 is placed on the jig 008, it is slightly curved. During the clamping process of the catheter front end clamping assembly 201, the catheter pressing plate 211 moves down, the guide port 212 is open, and if the front end of the deflected catheter 007 is deflected, the deflected front end of the catheter 007 gradually approaches the center of the positioning port 213 along the edge 249 of the guide port 212, and finally enters the positioning port 213. The first catheter clamping jaw cylinder 207 drives the first catheter clamping jaw 208 and the second catheter clamping jaw 209 to clamp the front end of the catheter 007, and the catheter pressing plate 211 guides the deflected front end of the catheter 007, which is beneficial to the accurate clamping of the front end of the catheter 007 by the first catheter clamping jaw 208 and the second catheter clamping jaw 209.

[0061] As shown, Figure 10 , 11 As shown, the first catheter clamping jaw 208 is provided with a first clamping groove 214, and the second catheter clamping jaw 209 is provided with a second clamping groove 215. One end of the first clamping groove 214 is provided with a first clamping block 216, and one end of the second clamping groove 215 is provided with a second clamping block 217. Figure 9 As shown, when the catheter front end clamping assembly 201 is in a clamping state, a clamping space 218 is formed between the first clamping block 216 and the second clamping block 217, the clamping space 218 is through, and the clamping space 218 is smaller than the diameter of the catheter 007. Figure 7 As shown, when the first catheter clamping jaw 208 and the second catheter clamping jaw 209 clamp the catheter 007, the first clamping block 216 and the second clamping block 217 press the catheter 007, but not completely, avoiding damaging the catheter 007 while clamping the catheter 007. The clamping groove 263 formed by the first clamping groove 214 and the second clamping groove 215 is slightly larger than the catheter 007, and does not form extrusion to the catheter 007. The catheter 007 maintains a natural circular shape, and the catheter 007 is directed to the front, i.e. the direction of the first drop port chamber 004, so as to accurately position the catheter 007, which is beneficial to subsequent assembly.

[0062] As shown, Figure 8As shown, the inner wall of the first clamping groove 214 comprises a first arc surface 219 and a first downward inclined surface 220, the first downward inclined surface 220 is tangent to the first arc surface 219, the inner wall of the second clamping groove 215 comprises a second arc surface 221 and a second downward inclined surface 222, the second downward inclined surface 222 is tangent to the second arc surface 221. The clamping groove 263 is surrounded by the first arc surface 219, the second arc surface 221, the first downward inclined surface 220 and the second downward inclined surface 222, the clamping groove 263 comprises a circular area 250 and a squeezing area 251, when the catheter 007 is clamped by the first clamp block 216 and the second clamp block 217, the catheter 007 is deformed, the deformed part is located in the squeezing area 251, the first arc surface 219 and the second arc surface 221 are tightly attached to the catheter 007, and the catheter 007 is accurately positioned, and the catheter 007 faces the front, avoiding deflection or up and down displacement of the catheter 007.

[0063] As shown in Figure 10 , 11 As shown, the second catheter taking clamp finger 209 is provided with a side guide block 223 and a middle guide block 224, and the first catheter taking clamp finger 208 is provided with a side guide groove 225 and a middle guide groove 226. The side guide block 223 is inserted into the side guide groove 225, and the middle guide block 224 is inserted into the middle guide groove 226, which guides the clamping and loosening of the first catheter taking clamp finger 208 and the second catheter taking clamp finger 209, and the first clamping groove 214 and the second clamping groove 215 can be accurately positioned, which is beneficial to the accurate clamping and positioning of the catheter 007.

[0064] As shown in 12-14, the catheter middle clamping assembly 202 comprises a second catheter clamp jaw air cylinder 227, the second catheter clamp jaw air cylinder 227 is provided with a third catheter taking clamp finger 228 and a fourth taking clamp finger 229, and the second catheter clamp jaw air cylinder 227 is fixed on a second connecting plate 230. The third catheter taking clamp finger 228 is provided with a third through groove 231, and the third through groove 231 divides the third catheter taking clamp finger 228 into a third front sub-clamp finger 252 and a third rear sub-clamp finger 253. The fourth taking clamp finger 229 is provided with a fourth through groove 232, and the fourth through groove 232 divides the fourth taking clamp finger 229 into a fourth front sub-clamp finger 254 and a fourth rear sub-clamp finger 255, and when the catheter middle clamping assembly 202 is in a clamping state, the third through groove 231 and the fourth through groove 232 jointly form a middle clamping groove 33.

[0065] As shown in Figure 3 , 19As shown, the catheter 007 is arranged on two jigs 008, and each jig 008 has two clamping blocks 009, and the clamping block 009 is provided with a catheter slot 010. Since the catheter 007 is relatively soft, it is not straight on the jig 008, but is in a natural curved state, and the position of the catheter 007 part at the clamping block 009 is more certain, and the position of the other catheter 007 part is not certain. As shown in the figure, Figure 5 As shown, the process of clamping the catheter 007 by the catheter middle clamping assembly 202: the third catheter taking clamp finger 228 and the fourth taking clamp finger 229 move downward to the catheter 007, the clamping block 009 is inserted into the third through slot 231 and the fourth through slot 232, the third front sub-clamp finger 252 and the fourth front sub-clamp finger 254 are located on one side of the clamping block 009, the third rear sub-clamp finger 253 and the fourth rear sub-clamp finger 255 are located on the other side of the clamping block 009, the position of the catheter 007 part on both sides of the clamping block 009 is more certain, the third front sub-clamp finger 252 and the fourth front sub-clamp finger 254 clamp from the front of the clamping block 009, and the third rear sub-clamp finger 253 and the fourth rear sub-clamp finger 255 clamp from the rear of the clamping block 009, which can accurately clamp the catheter 007.
