Description

Technical Field

[0001] The invention belongs to the field of novel medical technology, and in particular relates to an automatic assembly machine for a core rod retaining spring. Background Art

[0002] Generally, the structure of syringes produced by syringe production equipment on the market is relatively simple, with one assembly line, and the internal core rod can be pulled out after completion, resulting in secondary or even multiple uses.

[0003] A new device is added on the basis of the original structure. The main function of this device is to fix the retaining spring (which acts as a limiter) at the exact center of the core rod, so that the retaining spring will be stuck inside the syringe after the syringe is used, making it impossible to pull out the core rod. If it is pulled out forcibly, the core rod will break and cannot be used again, thus achieving the effect of forcing it to be unable to be used a second time. Summary of the invention

[0046] The core rod turntable 22 and the retaining spring turntable 42 rotate synchronously towards each other, the cam follower 23 obtains the core rod from the corresponding core rod feeding mechanism 1 and clamps and rotates, the retaining spring fixing module 43 absorbs the retaining spring from the corresponding retaining spring feeding mechanism 3 and fixes and rotates, and then the two are in a tangent position, and the retaining spring is assembled to the core rod through the retaining spring fixing module 43. The assembled core rod continues to rotate with the core rod turntable 22 for detection and discharge, and the retaining spring turntable 42 continues to rotate to absorb new retaining springs for assembly.

In the clockwise direction, they are the assembly station, the first rotation station, the second rotation station, and the discharge station, respectively.

[0051] In the station marking module 8 on the retaining ring turntable 42, four station marking rods 82 are arranged, and one station marking rod 82 is arranged at the 1-2 o'clock position, one station marking rod 82 is arranged at the 4-5 o'clock position, one working marking rod 82 is arranged at the 7-8 o'clock position, and one station marking rod 82 is arranged at the 1-11 o'clock position.

[0052] Furthermore, if Figure 7 , 8 As shown, it also includes a circlip distribution mechanism 7, which is arranged between the circlip feeding mechanism 3 and the circlip turntable mechanism 4, and is used to distribute the circlips provided by the circlip feeding mechanism 3 to the circlip turntable mechanism 4 one by one.

[0053] The retaining spring dividing mechanism 7 includes an arc material channel 71, a retaining spring pulling-down module 72, a retaining spring blanking platform 73, and a guide and limiting module 74. The arc material channel 71 is connected to the feeding channel 12 of the retaining spring feeding mechanism 3. The retaining spring pulling-down module 72 is arranged on the arc material channel 71 and is used to pull the retaining spring on the feeding channel 12 of the retaining spring feeding mechanism 3 down into the arc material channel 71. The retaining spring blanking platform 73 is arranged at the lower end of the arc material channel 71, and a part of the guide and limiting module 74 passes through the retaining spring blanking platform 73.

[0054] When the retaining ring is adsorbed, the thrust cylinder is actuated to move the first fixed seat 432 and the second fixed seat 433 of the clamping fixed suction head 434 toward the discharge port at the lower end of the arc material channel 71 for loading the retaining ring. After reaching the position, the vacuum generator is actuated, and the fixed suction head 434 adsorbs and fixes the retaining ring.

[0055] The retaining spring pull-down module 72 includes a fixed rod 721, a tension spring 722, a pressure plate 723, and a first thrust cylinder 724. One end of the pressure plate 723 abuts against a position between the arc material channel 71 and the feeding material channel 12, and the other end is connected to the upper side of the fixed rod 721 through the tension spring 722. Any position in the middle area of ​​the pressure plate 723 is hinged to the lower side of the fixed rod 721. A clamping cylinder 7241 is provided at the front end of the piston rod of the first thrust cylinder 724, and a clamping claw 7242 is provided on the clamping claw cylinder 7241 for clamping the retaining spring.

[0056] The clamping spring is sent to the end by the feeding channel 12, and the front clamping spring lies on the small block, and the forward direction is blocked by the pressing plate 723. When the clamping spring needs to be grabbed, the first propulsion cylinder 724 is pushed forward, and the clamping claws 7242 will be on the left and right sides of the clamping spring. The clamping claw cylinder 7241 clamps and holds the clamping spring. The first propulsion cylinder 724 is retracted again, driving the clamping claws 7242 and the clamping spring to move forward, and they will pass the small blocking point at the lowest position of the pressing plate 723. When the clamping claw cylinder 7241 is released again, the clamping spring will slide down along the arc material channel 71, and the top of the pressing plate 723 is connected to the spring 722, so that the small blocking point at the lowest position blocks the front end of the clamping spring downward, so that there is no need to worry too much about the size error of the clamping spring, and the clamping spring can be blocked, and the first propulsion cylinder 724, the clamping claw cylinder 7241 and the clamping claw 7242 can pull the clamping spring over.

[0057] A limiting column 711 is arranged on one side of the arc channel 71 close to the retaining spring turntable 42 , a fixing block 435 is arranged on the side of the first fixing seat 432 on the retaining spring fixing module 43 facing the arc channel 71 , and a matching groove is arranged on the side of the fixing block 435 facing the limiting column 711 .

[0058] The guide limit module 74 includes a limit cylinder 741 and a semicircular core puller 742. The semicircular core puller 742 passes through the retaining spring blanking platform 73 and is connected to the circular arc material channel 71. The limit cylinder 741 is arranged on one side and is connected to the lower end of the semicircular core puller 742 to drive it to move up and down.

[0059] In the initial state of the limiting cylinder 741, the semicircular core pulling 742 serves as a guide to allow the retaining spring to fall smoothly on the retaining spring blanking platform 73, and the limiting cylinder 741 drives the semicircular core pulling 742 to move downward. At this time, the upper end surface of the semicircular core pulling 742 is lower than the retaining spring blanking platform 73, and the falling retaining spring will fall on the retaining spring blanking platform 73. At the same time, it is pushed to a position close to the retaining spring by the fixed suction head 434 of the retaining spring fixing module 43, and then the vacuum generator puts the fixed suction head 434 in a negative pressure adsorption state to adsorb the retaining spring, and then the limiting cylinder 741 is reset to prepare for the next step.

[0060] Furthermore, it also includes a retaining spring detection mechanism 6, which is arranged on the control cabinet 5 and located on the rotating side of the core rod turntable mechanism 2, and is used to detect whether the core rod and the retaining spring are qualified after assembly.

[0061] The retaining spring detection module is composed of a CCD camera, and determines whether the retaining spring is assembled in a proper position according to the imaging of the core rod.

[0062] Furthermore, if Fig. 9 As shown, it also includes a retaining spring positioning mechanism 9, at least one of which is provided and is located at one side of the rotating station after the assembly station of the core rod turntable mechanism 2.

[0063] The spring positioning mechanism 9 includes a lifting cylinder 91, a connecting piece 92, a positioning claw 93, and a second propulsion cylinder 94. The lifting cylinder 91 is vertically arranged on the control cabinet 5, and the output end is connected to the second propulsion cylinder 94 through the connecting piece 92 arranged horizontally. The output end of the second propulsion cylinder 94 is connected to the positioning claw 93.

[0064] In the initial position, the lifting cylinder 91 is in a raised state, and the second propulsion cylinder 94 is pushed forward so that the positioning claw 93 can clamp the retaining spring on the core rod, and then the lifting cylinder 91 is lowered to a specified stroke, so that the positioning claw 93 pulls the retaining spring down to a specified position, and then the second propulsion cylinder 94 retreats backward, the positioning claw 93 separates from the retaining spring, and the lifting cylinder 91 is reset, completing a process of pulling down the retaining spring.

[0065] The described circlip positioning mechanisms 9 can be provided with two in succession. If the first circlip positioning mechanism 9 fails to be pulled down, the circlip can be pulled down again by the second circlip positioning mechanism 9 .

[0066] After the clamping spring is pulled down, the clamping spring detection mechanism 6 performs detection, and according to the detection result, the material is discharged to different discharge ports through the discharge mechanism 10.

[0067] Furthermore, if Fig.10 As shown, it also includes a discharging mechanism 10, which is arranged on the control cabinet 5 and is located between the loading station and the rotating station of the core rod turntable mechanism 2, and is used to discharge qualified products and unqualified products respectively.

The unqualified product discharging port 102 is located between the loading station and the qualified product discharging port 101 of the core rod turntable mechanism 2, and the fourth propulsion cylinder 104 is arranged on the lower side of the core rod turntable mechanism 2, which is used to push the unqualified products off the core rod turntable mechanism 2 and drop them into the unqualified product discharging port 102.

[0069] The third propulsion cylinder 103 is arranged on the upper side of the cam follower 23 and is used to lift the spring mechanism of the cam follower 23 , so that the core rod lacks the limit of the spring mechanism and can be separated from the U-shaped groove on the core rod turntable 22 .

[0072] Step 1, the retaining ring is sent from the material turntable 11 to the feeding channel 12 under the action of the direct vibration feeder 13;

[0073] Step 2: The first propulsion cylinder 724 controls the pressing plate 723 from the outlet of the feeding channel 12, grabs the clip and pulls it back for a distance before releasing it, and it falls into the arc channel 71;

[0074] Step 3: After the retaining spring slides down the slideway on the arc material channel 71, the cylinder is pushed out, and the vacuum generator is turned on, so that the fixed suction head 434 sucks the retaining spring and temporarily fixes it;

[0075] Step 4: Rotate to the second rotation position, the third rotation work, no action;

[0076] Step 5. Rotate to the assembly station, push the cylinder out, and close the vacuum generator at the same time to fix the retaining ring on the core rod. If the core rod / retaining ring position deviates by chance and the two are not engaged, the retaining ring will fall off, resulting in defective products.

[0077] Step 6: Rotate to station No. 4, no action.

[0078] Step 7. Repeat steps 1-6.

[0081] Step 2: The core rod is fixed to the core rod turntable mechanism 2 and rotated to the assembly station. The double turntables work together, and the right retaining ring is pushed out by the propulsion cylinder to the core rod of the corresponding station on the left, and supported. Fig.11 As shown;

[0082] Step 3, rotate to the first rotating station, the spring positioning mechanism 9 starts to work, the second propulsion cylinder 94 controls the positioning claw 93 to grab the core rod and the lifting cylinder 91 controls it to slide from top to bottom, forcing the spring to be fixed at a certain position (at the 1 / 2 position of the core rod);

[0083] Step 4: Rotate to the second rotation position, and the second clip positioning mechanism 9 starts to work;

[0084] Step 5, the circlip detection mechanism 6 starts to work, and the circlip detection mechanism 6 detects from above whether there is a circlip fixed on the core rod and determines the next action. If not, it rotates to the next station; if yes, it is pushed out by the third propulsion cylinder 103;

[0085] Step 6, rotate to the discharging station, the fourth propulsion cylinder 104 pushes out the core rod, and the core rod pushed out at this position can be manually put back into the feeding channel 12 for the next round of fitting action.

[0086] Step 7. Repeat steps 1-6.
