Description

Technical Field

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

[0002] The existing disposable blood bag products are assembled by manual gluing of the catheter, blood bag and three-way joint. The operator glues a proper amount of cyclohexanone glue on one end of the catheter in the length direction and then inserts it into the blood bag or three-way joint. The assembly is all done manually. When the demand for the product is large, the operator frequently repeats the assembly, which is inefficient. Moreover, it is not easy for each operator to apply the glue evenly, and the stable and reliable assembly of the blood bag product cannot be ensured. Therefore, it is urgently necessary to develop a catheter gluing assembly mechanism. Summary of the invention

[0003] In view of the above problems, the utility model provides a catheter gluing assembly mechanism, which realizes the automatic gluing operation of the catheter and ensures that the gluing is uniform and reliable.

[0007] and a rear glue coating assembly, which includes a front-rear movable seat, a single-row glue coating head, a front-rear driving module, and a glue feed pump;

[0008] The upper lifting positioning plate and the lower lifting positioning plate are assembled to form a plurality of equally spaced positioning holes, which are used to reliably position the end of the catheter and ensure that the protrusion of the end of the catheter faces the corresponding glue coating head;

[0009] The front-to-back movable seat is supported on the upper surface of the upper plate by a front-to-back movable guide rail structure. A single row of gluing heads is arranged laterally at a position of the front-to-back movable seat close to the front initial positioning component. The number of the single row of gluing heads is the same as the number of positioning holes, and the spacing distance is the same. The glue inlet of each gluing head is connected to the glue feed pump at the rear through a pipeline. The front-to-back driving module is fixedly mounted on the rear of the upper plate, and the output end of the front-to-back driving module is connected to the front-to-back movable seat. The glue feed pump is fixedly mounted on the fixed structure of the equipment.

[0010] It is further characterized by:

[0011] The upper lifting and positioning plate includes a first lifting cylinder and an upper positioning plate, and the lower lifting and positioning plate includes a second lifting cylinder and a lower positioning plate. The upper part of the upper plate is connected to the first lifting cylinder through a lifting column, and the lower output end of the first lifting cylinder is connected to the upper positioning plate through a connecting plate. The upper positioning plate is arranged vertically, and its bottom edge is a first contour positioning edge. The bottom surface of the upper plate is connected to the second lifting cylinder through a connecting seat. The upper output end of the second lifting cylinder is connected to the lower positioning plate, and the lower positioning plate is arranged vertically, and its top edge is a second contour positioning edge. The first contour positioning edge and the second contour positioning edge are assembled and assembled to form a plurality of positioning holes.

[0012] The position of the forward and backward movable seat body corresponding to the rising column is provided with an avoidance notch, which ensures the reliable forward and backward movement of the forward and backward movable seat body;

[0013] There are two glue feed pumps, and each glue coating head is externally connected to an output port of a three-way joint. The two glue feed pumps are respectively connected to the corresponding input ports of the three-way joint through independent pipelines, so that the glue coating head is provided with two parallel glue feed ports. When one of the ports fails, the other port can still reliably and stably discharge glue.

[0014] After the utility model is adopted, after the catheter moves to the set position, the upper lifting positioning plate and the lower lifting positioning plate are assembled and the positioning holes are used to complete the reliable positioning of the catheter. Then the front and rear driving modules drive the front and rear moving seat to move, so that each glue coating head is reliably located at the outer circumference of the end of the catheter. Then the glue feeding pump is activated to send a certain amount of colloid into the glue coating head to complete the stable and reliable gluing operation of the catheter end, which realizes the automatic gluing operation of the catheter and ensures uniform and reliable gluing.
