Description

Technical Field

[0001] The present invention relates to the field of automated production equipment, in particular to automatic assembly equipment for heparin caps. Background Art

[0002] Heparin caps are typically used with IV catheters. The cap connector can be repeatedly punctured for patients to receive infusions and medications. Heparin sodium is injected to prevent blood reflux and anticoagulation. Using a heparin cap to seal the catheter can extend the life of the IV catheter, alleviate patient pain, reduce medical expenses, and improve nurse efficiency.

[0003] Heparin caps are widely used in clinical medicine due to their advantages. Heparin caps consist of a rubber pad and an injection base. Production requires placing the pad into the mounting opening of the injection base, followed by heat pressing of the base, which deforms the opening and secures the pad. The injection base and rubber pad are relatively small, making manual assembly of heparin caps time-consuming, labor-intensive, and inefficient. Heat pressing poses significant safety risks and can easily injure assemblers. Therefore, there is an urgent need for equipment that can efficiently produce heparin caps. Summary of the Invention

[0004] The object of the present invention is to provide an automatic heparin cap assembly device to solve one or more technical problems existing in the prior art and at least provide a beneficial option or create conditions.

[0005] The technical solutions adopted to solve the above technical problems are:

[0006] A heparin cap automatic assembly device comprising:

[0007] A hot pressing device, wherein the hot pressing device is provided with a hot pressing head that moves up and down, and a hot pressing end is provided at the lower end of the hot pressing head;

[0008] A material supply device, wherein the material supply device is provided with an injection seat supply port for continuously supplying the injection seat and a rubber pad supply port for continuously supplying the rubber pad;

[0009] An injection seat feeding device, wherein the injection seat feeding device is provided with an injection seat feeding trough, and the injection seat feeding trough slides back and forth between the injection seat feeding port and directly below the hot pressing end;

[0010] The rubber pad feeding device is provided with a rubber pad feeding claw for taking and placing the rubber pad, and the rubber pad feeding claw slides back and forth between the rubber pad feeding port and the rubber pad feeding port just below the hot pressing end.

[0011] The beneficial effects of the present invention are as follows: the injection seat is transported from the injection seat feed port to the bottom of the hot pressing head via the injection seat feeding trough, the rubber pad is transported from the rubber pad feed port to the injection seat of the injection seat feeding trough via the rubber pad feeding claw, and then the injection seat with the rubber pad is hot-pressed downwardly by the hot pressing head. The heparin cap automatic assembly equipment of the present invention combines the injection seat and the rubber pad via the rubber pad feeding claw and the injection seat feeding trough, and then presses down via the hot pressing head to hot-press the heparin cap, thereby automating the assembly of the heparin cap, improving efficiency and yield, and avoiding harm to the assembly personnel during the hot pressing process.

[0012] As a further improvement to the above technical solution, the hot pressing device further includes a hot pressing cylinder, which is mounted downwardly above the hot pressing head and is fixedly connected to the lower end of the piston rod of the hot pressing cylinder. Through this technical solution, the hot pressing head is driven by the hot pressing cylinder, allowing it to move up and down, and during the hot pressing process, the port of the injection seat can be bent and deformed to complete the assembly.

Through the above technical solution, the loading pressing plate is driven to slide left and right by the loading cylinder, so that the injection seat loading trough of the loading pressing plate can slide from the injection seat feed port to the bottom of the hot press head; when the loading pressing plate slides to the right, the blocking portion on its left side can block the injection seat feed port to prevent the injection seat from falling from the injection seat feed port.

[0014] As a further improvement to the above technical solution, a pusher assembly is provided at the front right portion of the injection station loading device. The pusher assembly comprises a pusher plate that slides back and forth and a pusher cylinder that drives the pusher plate to slide back and forth. A pusher portion is provided at the rear end of the pusher plate, and an inclined material receiving chute is provided at the lower rear side of the loading and pressing plate. Through the above technical solution, the pusher assembly pushes the hot-pressed heparin caps backward from the loading and pressing plate, causing them to fall into the material receiving chute and slide out for collection.

[0015] As a further improvement to the above technical solution, a push-up assembly is provided at the rear right portion of the injection seat loading device. This push-up assembly comprises a push-up plate that slides back and forth, and a push-up cylinder that drives the push-up plate's back and forth movement. A concave arc-shaped tightening portion is provided at the front end of the push-up plate. With this technical solution, the injection seat has a cylindrical outer circumference, and the push-up cylinder drives the push-up plate's back and forth movement. This allows the tightening portion to press the injection seat forward into the injection seat loading trough during assembly and hot pressing, ensuring assembly repeatability.

[0016] As a further improvement to the above technical solution, the material supply device includes an injection seat material supply assembly and a rubber pad material supply assembly.

Through the above technical solution, the injection seat is continuously transported to the injection seat material supply port by the injection seat vibration disk and the injection seat material supply direct vibration. The injection seat material supply direct vibration enables the injection seat to keep being transported forward. When the injection seat material supply trough is aligned with the injection seat material supply port, the injection seat can enter the injection seat material supply trough.

[0017] As a further improvement of the above technical solution, the rubber pad feeding assembly includes a rubber pad feeding straight vibration and a rubber pad vibration disk, the rubber pad feeding straight vibration is provided with a rubber pad material channel, the front end of the rubber pad material channel is provided with an offset loading plate and an offset cylinder for driving the offset loading plate to slide left and right, the rubber pad feeding port is provided at the rear side of the offset loading plate, the rubber pad feeding port is provided with a rearward opening, and the rubber pad feeding port is flush with the rubber pad material channel. Through the above technical solution, the rubber pad is continuously conveyed forward on the rubber pad material channel by the rubber pad vibration disk and the rubber pad feeding straight vibration, the offset loading plate is driven to slide left and right on the front side of the rubber pad material channel by the offset cylinder, when the rubber pad feeding port is aligned with the rubber pad material channel, the rubber pad enters the rubber pad feeding port from the rubber pad material channel, and when the offset cylinder is actuated and the rubber pad feeding port is offset from the rubber pad material channel, the rubber pad is blocked in the rubber pad material channel to prevent the rubber pad from falling from the rubber pad material channel.

[0018] As a further improvement to the above technical solution, the rubber pad feeding device is located on the right side below the hot press head, and the rubber pad feeding claw is mounted above the rubber pad feeding port in a lateral sliding manner. The rubber pad feeding device is provided with a lateral translation cylinder, which is used to drive the rubber pad feeding claw to slide left and right. With the above technical solution, the lateral translation cylinder drives the rubber pad feeding claw to move left and right, so that after the rubber pad is grabbed from the rubber pad feeding port, the rubber pad feeding claw can be moved to the bottom of the hot press head to place the rubber pad.

[0019] As a further improvement to the above technical solution, the rubber pad loading gripper includes a lifting slide cylinder and a nozzle mounting plate. The lifting slide cylinder is arranged in the vertical direction, and the nozzle mounting plate is fixedly connected to the slide of the lifting slide cylinder. The nozzle mounting plate is mounted with a rubber pad suction nozzle for absorbing rubber pads. With the above technical solution, the rubber pad suction nozzle can absorb the rubber pad, and the slide cylinder drives the nozzle mounting plate up and down, so that the rubber pad loading gripper can achieve the rubber pad picking and placing action through the coordination of up and down sliding and suction action.

[0020] As a further improvement to the above technical solution, the rubber pad suction nozzle is located on the lower side of the nozzle mounting plate, and a pressure plate is also provided on the lower side of the nozzle mounting plate. The pressure plate is slidably mounted on the outer side of the rubber pad suction nozzle in the vertical direction, and the nozzle mounting plate is equipped with a pressure cylinder for driving the pressure plate to slide up and down. With the above technical solution, when the rubber pad suction nozzle descends to place the adsorbed rubber pad into the injection seat, the pressure plate is driven downward by the pressure cylinder, so that the downward pressure plate can ensure that the rubber pad is pressed into the injection seat, avoiding assembly abnormalities that affect the subsequent hot pressing action.

[0046] The rubber pad loading device 300 is arranged on the right side below the hot pressing head 110, and the rubber pad loading claw is installed above the rubber pad feeding port 541 for sliding along the left and right directions. The rubber pad loading device 300 is provided with a translation cylinder 310 arranged along the left and right directions, and the translation cylinder 310 is used to drive the rubber pad loading claw to slide left and right.

[0047] The rubber pad feeding gripper includes a lifting slide cylinder 320 and a suction nozzle mounting plate 330. The lifting slide cylinder 320 is arranged in the up and down directions. The suction nozzle mounting plate 330 is fixedly connected to the slide of the lifting slide cylinder 320. The suction nozzle mounting plate 330 is installed with a rubber pad suction nozzle 331 for adsorbing the rubber pad. The rubber pad suction nozzles 331 are arranged at equal intervals along the left and right sides, and the arrangement spacing is consistent with the arrangement spacing of the injection seat feeding trough 211.

[0048] The rubber pad suction nozzle 331 is arranged on the lower side of the suction nozzle mounting plate 330, and a pressing plate 340 is also provided on the lower side of the suction nozzle mounting plate 330. The pressing plate 340 is slidably sleeved on the outer side of the rubber pad suction nozzle 331 along the up and down directions. The suction nozzle mounting plate 330 is installed with a pressing cylinder 350 for driving the pressing plate 340 to slide up and down.

[0049] A pushing assembly 600 and a lifting assembly 700 are respectively provided at the front and rear of the right side of the injection seat loading device 200. The pushing assembly 600 is provided with a pushing plate 610 that slides back and forth and a pushing cylinder 620 that drives the pushing plate 610 to slide back and forth. Four pushing parts 611 are provided at the rear end of the pushing plate 610. An inclined material receiving slide 230 is provided at the lower rear side of the loading and pressing plate 210. The lifting assembly 700 is provided with a lifting plate 710 that slides back and forth and a lifting cylinder 720 that drives the lifting plate 710 to slide back and forth. Four concave arc-shaped tightening parts 711 are provided at the front end of the lifting plate 710.

[0050] Reference Figures 1 to 7 When using the heparin cap automatic assembly device of the present invention to assemble heparin caps:

[0051] First, pour the injection seat incoming material and the rubber pad incoming material into the injection seat vibration plate 420 and the rubber pad vibration plate 520 respectively, so that the injection seat vibration plate 420 can continuously transport the injection seat to the injection seat incoming material direct vibration 410; the rubber pad vibration plate 520 can continuously transport the rubber pad to the rubber pad incoming material direct vibration 510.

[0052] The injection seat is sent to the injection seat feed port 412 via the injection seat material channel 411 on the injection seat material straight vibration 410 and falls forward from the injection seat feed port 412 into the injection seat loading trough 211. The loading cylinder 220 drives the loading pressing plate 210 to slide to the right: the blocking part 212 on the left part of the loading pressing plate 210 blocks the injection seat feed port 412; the injection seat loading trough 211 drives the injection seat therein to move to the right to the bottom of the hot pressing head 110.

[0053] At this time, the ejection cylinder 720 of the ejection assembly 700 extends forward, driving the ejection plate 710 to move forward. The ejection portion at the front end of the ejection plate 710 presses the injection seat in the injection seat loading groove 211 forward to prevent the injection seat from swinging in the injection seat loading groove 211.

[0054] The rubber pad is transported forward via the rubber pad material channel 511 on the rubber pad inlet vibration machine 510 to the rubber pad feed port 541 of the offset loading plate 540. The offset cylinder 530 drives the offset loading plate 540 to slide leftward, causing the rubber pad feed port 541 to be offset from the rubber pad material channel 511. Next, the lifting slide cylinder 320 drives the nozzle mounting plate 330 to move up and down, allowing the rubber pad suction nozzle 331 to absorb the rubber pad at the rubber pad feed port 541 and lift it upward.

[0055] Then, the translation cylinder 310 drives the rubber pad loading claw to move to the left, and the rubber pad loading claw moves to between the hot pressing head 110 and the loading pressing plate 210. The rubber pad suction nozzle 331 that adsorbs the rubber pad descends and places the rubber pad in the injection seat of the injection seat feeding groove 211 and then resets upward. The translation cylinder 310 drives it to reset to the right above the rubber pad feeding port 541.

[0056] When the rubber pad suction nozzle 331 descends to place the adsorbed rubber pad in the injection seat, the negative pressure of the rubber pad suction nozzle 331 is interrupted, and the pressing cylinder 350 drives the pressing plate 340 to move downward, and the downward pressing plate 340 ensures that the rubber pad is pressed into the injection seat.

[0057] Then, the hot pressing cylinder 120 drives the hot pressing head 110 to move downward, so that the hot pressing end 111 performs hot pressing on the injection seat on the loading pressing plate 210 to deform it and press the rubber pad to fix it, thereby completing the assembly.

[0058] The hot pressing head 110 that has completed hot pressing retracts upward, and the ejecting cylinder 720 drives the ejecting plate 710 to retract backward. The pushing cylinder 620 of the pushing assembly 600 extends backward, driving the pushing plate 610 to move backward. The pushing portion 611 at the rear end of the pushing plate 610 pushes the heparin cap that has completed hot pressing in the injection seat loading groove 211 backward, so that the heparin cap falls into the material receiving slide 230 and slides out.

[0059] The injection seat feeding trough 211 in the present invention can be set to any number. The number of the hot pressing ends 111, the number of the injection seat material channels 411, the number of the rubber pad material channels 511 and the number of the rubber pad feeding ports 541 are all consistent with the number of the injection seat feeding troughs 211 and the arrangement spacing is consistent, so that the injection seat and the rubber pad can be assembled in batches to improve efficiency.

[0060] The above specifically describes the preferred embodiments of the present invention, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
