Description

Technical Field

[0001] The invention belongs to the technical field of medical device production equipment and relates to an automatic assembly line, in particular to an automatic assembly line for syringes. Background Art

[0002] A syringe is a common medical device. It consists of a syringe with a small hole at the front end and a matching piston core rod. The syringe is used to inject a small amount of liquid or gas into areas that are inaccessible by other methods or to extract it from those places. When the core rod is pulled out, the liquid or gas is sucked into the small hole at the front end of the syringe, and when the core rod is pushed in, the liquid or gas is squeezed out. The process of extracting or injecting gas or liquid with a syringe and needle is called injection.

[0003] In current medical treatment, syringes can be reused when using the same medicine, but the injection needle that comes into contact with the patient needs to be replaced, which requires the use of disposable needles. Disposable needles can save medicine and have no side effects on patients.

[0004] However, in the traditional disposable needle assembly production line, manual sorting is required in the rejection process. Such sorting is not only not strict enough, but also wastes time and resources, reduces the speed of disposable needle assembly production, and also reduces the quality of disposable needle assembly production, thereby reducing production benefits.

[0050] In the above-mentioned automatic assembly line for syringes, a horizontally arranged material shifting rod I9 is ​​provided on the translation frame I2, and both ends of the material shifting rod I9 are fixedly connected with horizontally arranged guide rods I10, and two horizontally arranged guide sleeves I11 are fixedly connected to the translation frame I2 and the guide rods I10 pass through the guide sleeves I11.

[0051] In the above-mentioned automatic assembly line of syringe, the two ends of the material-dispensing rod 19 are provided with horizontally protruding material-dispensing heads 19a, and the material-dispensing heads 19a are wedge-shaped. The material-dispensing heads 19a are wedge-shaped, which are convenient for inserting between two syringes of the tooling strip, and are convenient for the advantage of accurate material dispensing.

[0052] In the above-mentioned automatic assembly line for syringes, the guide sleeve I11 is sleeved with a spring I12, and the two ends of the spring I12 respectively abut against the material-moving rod I9 and the translation frame I2. When unloading, when the fork I3 pushes the syringe, the material-moving rod I9 abuts against the outer wall of the syringe and compresses the spring I12. When the fork I3 lifts the syringe from the positioning rod, under the action of the elastic force of the spring I12, the material-moving rod I9 pushes the syringe horizontally outward to remove the syringe from the tooling bar, which has the advantages of simple structure and good unloading effect.

[0053] In the above-mentioned automatic assembly line of syringes, the workbench is fixedly connected with a limit rod I13 and the limit rod I13 is arranged parallel to one side of the fork I3 and the limit rod I13 is provided for the tooling strip to abut against. By providing the limit rod I13 for the tooling strip to abut against, when the translation frame I2 pushes the fork I3 to the tooling strip, the tooling strip can abut against the limit rod I13, which has a better limit effect and enables the unloading to proceed smoothly.

[0054] In the above-mentioned automatic assembly line for syringes, a plurality of blocking wheels I14 are axially fixedly connected to the workbench, the blocking wheel I14 is located on one side of the roller I4, the blocking wheel I14 is located on the lower side of the fork I3, and the lower end of the fork I3 can abut against the blocking wheel I14. By providing the above-mentioned blocking wheel I14, the fork I3 can be restricted from falling off from the translation frame I2, which has the advantage of reliable operation.

[0055] In the above-mentioned automatic assembly line for syringes, a feed opening is provided on one side of the workbench, and a material guide trough I15 is provided at the feed opening. The lower end of the material guide trough I15 is connected to the workbench, and the notch at the lower end of the material guide trough I15 has a blocking plate I16 and a lifting cylinder I8 that drives the blocking plate I16 up and down. The lifting cylinder I8 can drive the blocking plate I16 to rise and block the notch of the material guide trough I15. The notch of the material guide trough I15 is blocked by driving the blocking plate I16 by the lifting cylinder I8, so that the syringe can be blocked in the material guide trough I15, which has the advantage of being more convenient to use.

[0056] Compared with the prior art, the automatic assembly line of the syringe has the following advantages:

[0057] 1. The automatic assembly line of the syringe uses a conveying mechanism to make the tooling strip pass through the above-mentioned device in sequence to complete the assembly of the syringe, which has the advantages of high assembly efficiency and high qualified rate of assembled syringes;

[0058] 2. The lifting cylinder C3 drives the lifting plate C2 to descend and insert the needle tube into the corresponding syringe, and then the cylinder C8 drives the needle rubbing plate C7 to move, so that the needle rubbing plate C7 drives the needle tube to rotate around its axis, so that the glue is evenly coated between the needle tube and the needle seat, which has the advantage of better gluing effect;

[0059] 3. The translation cylinder I7 drives the translation frame I2 to move horizontally so that the abutting surface I3b of the fork I3 abuts against the roller I4. Since the abutting surface I3b is inclined, the translation frame I2 drives the fork I3 to move horizontally and longitudinally. At the same time, the roller I4 pushes the fork I3 to move up and down, so that the fork I3 pushes the syringe upward to remove the syringe from the positioning rod, which has the advantages of convenient unloading and not easy to damage the syringe.

[0060] 4. When the shift fork I3 pushes the syringe, the material pusher rod I9 rests against the outer wall of the syringe and compresses the spring I12. When the shift fork I3 lifts the syringe from the positioning rod, under the action of the elastic force of the spring I12, the material pusher rod I9 pushes the syringe horizontally outward to remove the syringe from the tooling bar, which has the advantages of simple structure and good material unloading effect.
