Description

Technical Field

[0001] The utility model relates to the field of infusion set assembly equipment, in particular to a high-efficiency Y-type three-way assembly device for an infusion set. Background Art

[0002] An infusion set is a medical device composed of an intravenous needle, an infusion hose, a drug filter, a flow regulator, a drip pot, a bottle stopper puncture device and other components. The Y-type tee of the infusion set is also one of the components of the infusion set. It can connect two infusion hoses, mix different drug solutions in proportion, and then inject them into the patient's veins. Therefore, the Y-type tee has hose connectors at two ends for connecting infusion hoses, and the last end serves as an injection head. The two hose connectors of the Y-type tee are a straight head and an oblique joint. The straight head is coaxial with the injection head, and the oblique joint is inclined on the upper surface of the Y-type tee body, so that the Y-type tee is Y-shaped.

[0003] The Y-type three-way assembly device of the infusion set is one of the devices of the infusion set assembly equipment. The hose conveying device in the infusion set assembly equipment can clamp the infusion hose and rotate it along the track of the guide rail, and the assembly devices of each station of the infusion set are distributed around the hose conveying device. The Y-type three-way assembly device of the infusion set is one of the stations, which can assemble the Y-type three-way and the infusion hose together. Since the direct head of the Y-type three-way and the injection head are in a coaxial state, it is only necessary to straightly convey the Y-type three-way through the vibration plate and make the oblique joint face upward to carry out the assembly of the direct head of the Y-type three-way. At this time, the assembly of the direct head will be carried out first. After the assembly of the direct head and the infusion hose is completed, the assembly of the oblique joint will be carried out. When assembling the direct head of the Y-type three-way, as the Y-type three-way moves to the corresponding position in an orderly manner under the action of the vibration plate, the three-way clamping mechanism will clamp the Y-type three-way and the infusion hose for assembly, completing the assembly between the Y-type three-way and the infusion hose.

[0004] Therefore, when assembling the direct head of the Y-type tee and the infusion hose, it mainly involves a vibration plate for conveying the Y-type tee, a tee clamping mechanism for clamping the Y-type tee, and a hose conveying device for conveying the infusion hose. The vibration plate is an existing device, and its specifications cannot be changed at will. Therefore, the number of conveying tracks on the vibration plate for outputting the Y-type tee is fixed, and the hose conveying device has enough space to place the hose clamping rack for clamping the infusion hose. Even if the number of hose clamping racks is twice the conveying tracks of the vibration plate, the normal operation of the hose conveying device can be guaranteed, resulting in an inequality between the number of Y-type tees that can be assembled at one time and the number of infusion hoses that can be assembled at one time. In this case, even if the number of clamping arms of the tee clamping mechanism is doubled, the actual number of Y-type tees and infusion hoses that can be assembled at one time cannot be increased, which ultimately leads to the ineffective utilization of assembly resources, affecting the assembly efficiency of the Y-type tee. Summary of the invention

[0005] The utility model aims to solve the existing technical problem by providing a high-efficiency Y-type three-way assembly device for an infusion set, which can effectively improve the assembly efficiency between the Y-type three-way and the infusion hose without changing the number of conveying tracks of the vibration plate, thereby improving the overall efficiency of the infusion set.

[0036] The method of using the utility model is as follows:

[0037] The vibration plate 7 and the vibrator 9 are both existing vibration devices that can generate vibration force, so that the product can be moved in an orderly manner under the action of the vibration force. When the vibration plate 7 is started, the Y-shaped tees 6 initially placed in the vibration plate 7 in large quantities will be fed into the conveying track 10 from the feeding port 701 of the vibration plate 7 under the action of the vibration force. At this time, the vibrator 9 is in a vibrating state, and the vibrator 9 can exert the vibration force on the conveying track 10 on the upper surface of the conveying plate 8, so that the Y-shaped tees 6 entering the conveying track 10 The tee 6 can move backward in an orderly manner under the action of the vibration force. At this time, the straight head 601 of the Y-type tee 6 faces backward, the oblique joint 602 of the Y-type tee 6 faces upward, and the injection head 603 of the Y-type tee 6 faces forward. The inner walls on both sides of the upper acting part of the conveying track 10 are provided with limiting ribs 1001. The oblique joint 602 of the Y-type tee 6 is restricted between the limiting ribs 1001 on the left and right sides, thereby ensuring that the Y-type tee 6 always remains in a non-shaking state when moving, and can be stably transferred to the rear end of the conveying track 10.

[0038] When the Y-type tee 6 is conveyed to the rear end port of the conveying track 10, the rear end port of the conveying track 10 is connected with the material passing notch 507 on the block 506. Under the push of the subsequent Y-type tee 6, the direct head 601 of the Y-type tee 6 located on the rear side will pass through the material passing notch 507. Since the diameter of the injection head 603 of the Y-type tee 6 is larger than the diameter of the main body of the Y-type tee 6, when the direct head 601 of the Y-type tee 6 passes through the material passing notch 507 backward, the injection head 603 can limit the Y-type tee 6 from moving backward, and the direct head 601 that passes through the material passing notch 507 backward can be clamped.

[0039] When the direct head 601 of the Y-type tee 6 passes backward through the material passing gap 507, the optical fiber detection probe installed in the optical fiber detection probe installation hole 508 can sense it at the first time. The optical fiber detection probe is the front-end component of the existing optical fiber sensor, which is used to receive signals. After detecting the corresponding object, it can feed back information to the optical fiber sensor, so that the screw cylinder 509 is synchronously opened after the optical fiber detection probe detects the Y-type tee 6. At this time, the piston rod of the screw cylinder 509 will directly penetrate into the conveying track 10 through the positioning hole 510, and the second Y-type tee 6 will be stopped by blocking the oblique joint 602, so that it will not interfere with the subsequent action of the Y-type tee 6 in the state to be clamped.

[0040] When the direct joint 601 of the Y-type tee 6 is in a clamped state, the front-rear shift cylinder 102 is started, and the piston rod of the front-rear shift cylinder 102 will be retracted inward into the front-rear shift cylinder 102. When the fixed plate 15 and the fixed seat 103 are fixed, the front-rear shift plate 16 moves forward stably along the trajectory of the first slide rail 17, thereby realizing the forward movement of the front clamping mechanism 3 and the rear clamping mechanism 4. After the front clamping mechanism 3 and the rear clamping mechanism 4 move forward to the actual required position, the front-rear shift cylinder 102 is closed, and then the lifting cylinder 205 is started, and the piston rod of the lifting cylinder 205 drives the connecting plate 207 to move downward, thereby realizing the lifting plate 20 , when the lifting plate 20 moves downward, the front clamping mechanism 3 and the rear clamping mechanism 4 move downward synchronously. After the front clamping mechanism 3 and the rear clamping mechanism 4 move downward to the actual required position, the lifting cylinder 205 stops running. At this moment, the distribution position of the front clamping mechanism 3 corresponds to the distribution position of the conveying track 10. The front clamping arms 303 on the clamping claws on the left and right sides of the front pneumatic fingers 302 are just on the left and right sides of the direct head 601 of the rearmost Y-type tee 6. Then the front pneumatic fingers 302 can be started. At this moment, the front pneumatic fingers 302 control the front clamping arms 303 on the clamping claws on the left and right sides to approach each other to clamp the Y-type tee 6, thereby completing the clamping work of the first batch of Y-type tees 6.

[0041] After the first batch of Y-shaped tees 6 are clamped by the front clamping mechanism 3, the material blocking cylinder 503 is started, so that the piston rod of the material blocking cylinder 503 drives the stopper 506 to move downward, so that the Y-shaped tee 6 is completely separated from the material passing notch 507, so that the Y-shaped tee 6 is conveniently clamped by the front clamping mechanism 3, and then the lifting cylinder 205 drives the front clamping mechanism 3 to move upward, so that the first batch of Y-shaped tees 6 are separated from the conveying track 10, and then the material blocking cylinder 503 can be started again to make the stopper 506 move downward. 06 is blocked at the rear side of the conveying track 10. At this time, the screw cylinder 509 can be started again to reset the piston rod of the screw cylinder 509, and the second Y-type tee 6 that was originally stopped is inserted into the material passing notch 507 on the block 506. When the optical fiber detection probe detects the second Y-type tee, the screw cylinder 509 is started again, and the piston rod of the screw cylinder 509 is inserted into the conveying track 10 again, and the third Y-type tee is stopped by blocking the oblique joint 602.

[0042] When the second Y-shaped tee 6 enters the material passing gap 507 under the push of the subsequent Y-shaped tee 6 and is sensed by the optical fiber detection probe installed in the optical fiber detection probe installation hole 508, the second clamping can be performed. When the second clamping is required, the left and right shift cylinder 202 can be started. At this time, the piston rod of the left and right shift cylinder 202 will drive the left and right shift plate 203 to move along the track of the second slide rail 19, thereby realizing the left and right movement of the front clamping mechanism 3 and the rear clamping mechanism 4. At this time, the rear clamping mechanism 4 moves to the position corresponding to the conveying track 10. The position of the front clamping mechanism 3 is staggered with the position of the conveying track 10. When the lifting cylinder 205 controls the front clamping mechanism 3 and the rear clamping mechanism 4 to move down to the actually required position, the rear clamping arms 403 on the left and right clamping claws of the rear pneumatic fingers 402 are just on the left and right sides of the new Y-type tee 6. When the rear pneumatic fingers 402 are started, the clamping claws on the left and right sides of the rear pneumatic fingers 402 will control the left and right rear clamping arms 403 to clamp the new Y-type tee 6. The stopper 506 moves down again under the action of the blocking cylinder 503, thereby completing the clamping work of the second batch of Y-type tees 6.

[0043] When the rear clamping arms 403 on the clamping claws on the left and right sides of the rear pneumatic fingers 402 clamp the second batch of Y-type tees 6, the lifting cylinder 205 will control the front clamping mechanism 3 and the rear clamping mechanism 4 to rise to the position corresponding to the hose end limiting mechanism 11, and the hose end limiting mechanism 11 is an existing limiting mechanism that can use the pressure of the cylinder to clamp the end of the hose for assembly through the upper and lower clamping plates after the hose clamping frame 35 of the hose conveying device is transported to the clamping position. After the hose end limiting mechanism clamps the hose end, the hose end is opposite to the direct head 601 of the Y-type tee 6. At this time, it is only necessary to control the front and rear shifting plates to move backward through the front and rear shifting cylinders to move the front and rear shifting plates backward, so that the front clamping mechanism 3 and the rear clamping mechanism 4 can move backward, so that the direct heads 601 of all Y-type tees 6 clamped by the front clamping mechanism 3 and the rear clamping mechanism 4 can be directly inserted into the corresponding hose ends, completing the assembly between the Y-type tee 6 and the infusion hose.

[0044] In summary, the utility model can control the front clamping mechanism 3 and the rear clamping mechanism 4 to move left and right through the left and right shifting mechanism 2, and the front clamping mechanism 3 and the rear clamping mechanism 4 can clamp and take out two batches of Y-type tees 6 from the conveying track 10 in a short time by means of left and right shifting, thereby realizing a double change in the number of Y-type tees 6 in disguised form. At this time, it is only necessary to cooperate with the hose clamping frame 35 that clamps the infusion hoses that are twice the number of the conveying track 10, so that the Y-type tees 6 that are twice the number of the conveying track 10 can be assembled at one time, which effectively improves the assembly efficiency.

[0045] A shift opening 206 is provided in the middle of the front and rear shift plates 16. The lower end of the piston rod of the lifting cylinder 205 passes downward through the shift opening 206 and is provided with a connecting plate 207. The existence of the shift opening 206 can ensure that the left and right movement of the left and right shift plates will not be restricted by the lifting cylinder 205, ensuring that the left and right shift plates 203 can be smoothly shifted left and right.

[0046] Symmetrical guide columns 208 are provided on the left and right sides of the upper surface of the connecting plate 207, and guide holes coaxial with the guide columns 208 are provided on the left and right sides of the left and right shift plates 203. A guide sleeve 209 matching the guide column 208 is provided in the guide hole, and the upper end of the guide column 208 passes upward through the corresponding guide sleeve 209. The existence of the guide column 208 can play a guiding role when the lifting plate 20 drives the front clamping mechanism 3 and the rear clamping mechanism 4 to move up and down, thereby ensuring the stability when clamping the Y-type tee 6.

[0047] A limit plate 210 corresponding to the position of the left and right shift plates 203 is provided on the upper surface of the left end of the front and rear shift plates 16. The existence of the limit plate 210 can effectively limit the travel of the left and right shift plates 203 when they move left, thereby preventing the left and right shift plates 203 from moving too far to the left, causing the guide column 208 to collide with the inner wall of the shift opening 206.

[0048] A plurality of front mounting parts 301 are evenly arranged on the front side wall of the lifting plate 20, and a plurality of rear mounting parts 401 are evenly arranged on the rear side wall of the lifting plate 20. At the same time, the positions of the front mounting parts 301 and the rear mounting parts 401 are staggered with each other, so that the front clamping mechanism 3 and the rear-front clamping mechanism 3 are distributed front and back, and the front clamping arm 303 and the rear clamping arm 403 can be adjacently distributed in parallel on the left and right, so that space resources are effectively utilized, and the stroke required for the front clamping mechanism 3 and the rear clamping mechanism 4 to move left and right for clamping two batches of Y-type tees 6 is controlled within the shortest range, thereby further improving the assembly efficiency of the Y-type tees 6.
