Description

Technical Field

[0001] The utility model relates to the technical field of blood bag product assembly, in particular to a catheter variable distance assembly mechanism. Background Art

[0002] The existing disposable blood bag products are assembled by manual gluing. The operator glues a proper amount of cyclohexanone glue on one end of a group of evenly spaced catheters in the length direction and then inserts them into the blood bag. The assembly is all done manually. Now, the insertion of the catheters and the blood bag needs to be performed by automated operation. However, since the intervals between the blood bags are relatively large when they are laid flat, if the catheters are arranged according to the intervals between the blood bags when gluing, the gluing mechanism needs to occupy a large amount of space. Therefore, it is necessary to develop a catheter margin assembly mechanism suitable for the insertion of the catheters and the blood bag. Summary of the invention

[0003] In view of the above problems, the utility model provides a variable-distance assembly mechanism for a catheter, which realizes the variable-distance assembly of the catheter and the blood bag and saves space on the entire production line.

[0008] and a plurality of sets of catheter clamping mechanisms, each set of catheter clamping mechanisms comprising a connecting bracket, a front clamping jaw, and a rear clamping jaw, wherein the connecting bracket comprises a horizontal plate and a vertical plate arranged in a front-to-back direction;

[0009] A forward and backward driving module is arranged on one of the supporting side beams, and the bottom supporting ends at both ends of the mounting bracket in the length direction are respectively supported on the corresponding forward and backward tracks of the two supporting side beams, and the output end of the forward and backward driving module is fixedly connected to the bottom supporting end of one of the mounting brackets, and a first lifting driving mechanism is fixedly installed on the top of the vertical connecting plate of the mounting bracket, and the guide rail pair of the vertical movable vertical plate is embedded in the first vertical track on the front end surface of the vertical connecting plate, and the lower output end of the first lifting driving mechanism is directly or indirectly connected to the vertical movable vertical plate, and the front end surface of the vertical movable vertical plate is arranged on both side areas There is a second vertical track, the guide rail pair of the horizontal vertical plate is embedded in the second vertical track, and the front end surface of the vertical movable vertical plate is also provided with at least two groups of horizontal tracks, and each group of vertical plates is respectively embedded in the horizontal track through the guide rail pair. The number of the catheter clamping mechanism is the same as the number of the variable pitch guide grooves. The upper part of the vertical plate is respectively provided with a front protrusion, and the front protrusion is inserted into the corresponding variable pitch guide groove. When the variable pitch guide groove is lifted and lowered under the drive of the horizontal vertical plate, the front protrusion moves laterally along the variable pitch guide groove, thereby driving the catheter clamping mechanism to produce a lateral distance change.

[0010] It is further characterized by:

[0011] The vertical connection plate of the mounting bracket is provided with an upper limit stopper corresponding to the upper limit position of the vertical movable vertical plate, and the vertical connection plate of the mounting bracket is provided with a lower limit stopper corresponding to the lower limit position of the vertical movable vertical plate, so as to ensure that the position of the conduit is stable and reliable during the assembly operation;

[0013] The number of the catheter clamping jaw mechanisms is four, and the number of the variable pitch guide grooves is four;

[0014] The four groups of variable-pitch guide grooves are formed into a structure that expands the lateral distance from bottom to top;

[0015] When the transverse vertical plate moves downward to the lower limit position, the transverse distance between the catheters clamped by the adjacent catheter clamping mechanisms is the distance between the catheter insertion ports of the blood bag;

[0016] When the transverse vertical plate moves upward to the upper limit position, the transverse distance between the catheters clamped by the adjacent catheter clamping mechanisms is the distance between the adjacent glue coating ports of the glue coating mechanism.

[0017] After the utility model is adopted, the gluing station at the front of the catheter is transferred to the station where the blood bag needs to be inserted. At this time, the variable distance mechanism makes the catheter clamped by the catheter clamping claw mechanism be at the position with the smallest lateral distance. Then the front and rear driving modules and the first lifting driving mechanism are actuated to make the front clamping claw and the rear clamping claw of the catheter clamping claw mechanism be aligned with the length direction alignment end of the catheter. The front clamping claw and the rear clamping claw clamp the catheter. Then the front and rear driving modules and the first lifting driving mechanism are actuated again. At the same time, the second lifting driving mechanism is actuated, so that the variable distance mechanism makes the catheter clamped by the catheter clamping claw mechanism be at a position that matches the lateral distance with the blood bag tube mouth. Then the front and rear driving modules are actuated again to stably and reliably insert the catheter into the blood bag tube mouth. This realizes the variable distance assembly of the catheter and the blood bag and saves the space of the entire production line. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] A catheter variable pitch assembly mechanism, see Figure 1 and Figure 2 , which includes supporting side beams on both sides, a lifting module 30, a variable distance mechanism 40, and four sets of catheter clamping mechanisms 50;

[0024] The supporting side beams on both sides are specifically a left supporting side beam 10 and a right supporting side beam 20;

[0025] The lifting module 30 includes a mounting bracket 31, a first lifting drive mechanism 32, and a vertical movable stand 33;

[0026] The pitch-changing mechanism 40 includes a transverse vertical plate 41 and a second lifting drive mechanism 42. Four pitch-changing guide grooves 43 are arranged on the transverse vertical plate 41.

[0027] Each set of catheter clamping mechanism 50 includes a connecting bracket 51, a front clamping jaw 52, ​​and a rear clamping jaw 53. The connecting bracket 51 includes a horizontal plate 511 and a vertical plate 512 arranged in a front-to-back direction.

[0028] A forward and backward driving module 60 is arranged on the right supporting beam 20, and the bottom supporting ends 311 at both ends of the length direction of the mounting bracket 31 are respectively supported on the corresponding forward and backward tracks 1 of the two supporting side beams, and the output end of the forward and backward driving module 60 is fixedly connected to the bottom supporting end 311 on the right side of the mounting bracket, and the top of the vertical connecting plate 312 of the mounting bracket 31 is fixedly equipped with a first lifting driving mechanism 32, and the guide rail pair of the vertical movable vertical plate 33 is embedded in the first vertical track 2 on the front end surface of the vertical connecting plate 312, and the lower output end of the first lifting driving mechanism 32 is indirectly connected (the connecting mechanism is not drawn, and it can be a connecting block or a connecting rod) to the vertical movable vertical plate 32, and the second vertical track 3 is arranged on both sides of the front end surface of the vertical movable vertical plate 32, and the horizontal vertical plate 41 The guide rail pair is embedded in the second vertical rail 3, and the front end surface of the vertical movable vertical plate 32 is also provided with two groups of horizontal rails 4 arranged in parallel up and down. Each group of vertical plates 512 is respectively embedded in the horizontal rail 4 through the guide rail pair. The number of catheter clamping mechanisms 50 is the same as the number of variable pitch guide grooves 43, both of which are four. The upper part of the vertical plate 512 is respectively provided with a front protrusion, which is inserted into the corresponding variable pitch guide groove. In specific implementation, the front protrusion is a rotating shaft structure 513, and the rotating shaft structure 513 ensures that no wear occurs during movement; when the variable pitch guide groove 43 is lifted and lowered under the drive of the horizontal vertical plate 41, the rotating shaft structure 513 moves laterally along the variable pitch guide groove 43 under the interference of the horizontal rail 4, thereby driving the catheter clamping mechanism 50 to produce a lateral distance change.

[0029] In a specific implementation, the vertical connecting plate 312 of the mounting bracket 31 is provided with an upper limit stopper 5 corresponding to the upper limit position of the vertical movable vertical plate 32, and the vertical connecting plate 312 of the mounting bracket 31 is provided with a lower limit stopper 6 corresponding to the lower limit position of the vertical movable vertical plate 32, so as to ensure that the position of the conduit is stable and reliable during the assembly operation;

[0030] The four groups of front clamping jaws 52 and rear clamping jaws 53 act synchronously to clamp the corresponding end positions of the catheter in the length direction.

[0031] In specific implementation, the four sets of variable-pitch guide grooves 43 are formed into a structure that expands the lateral distance from bottom to top;

[0032] When the transverse vertical plate 41 moves downward to the lower limit position, the transverse distance between the catheters clamped by the adjacent catheter clamping jaw mechanisms 50 is the distance between the catheter insertion ports of the blood bag;

[0033] When the transverse vertical plate 41 moves upward to the upper limit position, the transverse distance between the catheters clamped by the adjacent catheter clamping jaw mechanisms 50 is the distance between the adjacent glue coating ports of the glue coating mechanism.

[0034] After the utility model is adopted, the gluing station at the front of the catheter is transferred to the station where the blood bag needs to be inserted. At this time, the variable distance mechanism makes the catheter clamped by the catheter clamping claw mechanism be at the position with the smallest lateral distance. Then the front and rear driving modules and the first lifting driving mechanism are actuated to make the front clamping claw and the rear clamping claw of the catheter clamping claw mechanism be aligned with the length direction alignment end of the catheter. The front clamping claw and the rear clamping claw clamp the catheter. Then the front and rear driving modules and the first lifting driving mechanism are actuated again. At the same time, the second lifting driving mechanism is actuated, so that the variable distance mechanism makes the catheter clamped by the catheter clamping claw mechanism be at a position that matches the lateral distance with the blood bag tube mouth. Then the front and rear driving modules are actuated again to stably and reliably insert the catheter into the blood bag tube mouth. This realizes the variable distance assembly of the catheter and the blood bag and saves the space of the entire production line.
